AbstractThe characteristics of bed material at selected sites

within the Sacramento–San Joaquin Delta, California, during 2010–13 are described in a study conducted by the U.S. Geological Survey in cooperation with the Bureau of Recla-mation. During 2010‒13, six complete sets of samples were collected. Samples were initially collected at 30 sites; how-ever, starting in 2012, samples were collected at 7 additional sites. These sites are generally collocated with an active streamgage. At all but one site, a separate bed-material sample was collected at three locations within the channel (left, right, and center). Bed-material samples were collected using either a US BMH–60 or a US BM–54 (for sites with higher stream velocity) cable-suspended, scoop sampler. Samples from each location were oven-dried and sieved. Bed material finer than 2 millimeters was subsampled using a sieving riffler and processed using a Beckman Coulter LS 13–320 laser diffrac-tion particle-size analyzer. To determine the organic content of the bed material, the loss on ignition method was used for one subsample from each location. Particle-size distributions are presented as cumulative percent finer than a given size. Median and 90th-percentile particle size, and the percentage of subsample mass lost using the loss on ignition method for each sample are also presented in this report.

IntroductionThe Sacramento–San Joaquin Delta (the Delta) is a

large interconnected network of mixed fluvial-tidal channels formed by the confluence of the Sacramento and San Joaquin Rivers. These two major rivers drain most of California’s Central Valley (fig. 1). The Delta is important ecologically and economically to the region. Bed material in the Delta is of par-ticular importance as it relates directly to channel morphology, sediment load and availability for marsh restoration, habitat for benthic invertebrates, potential contaminant transport (and exposure of those contaminants to aquatic organisms), and dredging activities in major shipping channels. Numerical models that predict hydrodynamics and sediment transport in the Delta are often used to evaluate management scenarios

(for example, Bever and MacWilliams, 2013; Achete and others, 2015). These models, however, require accurate sediment data such as bed-material particle size for calibra-tion and validation. In response to this need for sediment data, the U.S. Geological Survey (USGS), in cooperation with the Bureau of Reclamation, began a sampling program in 2010 to collect and analyze bed-material samples at 37 sites through-out the Delta, which continued through 2013.

Purpose and Scope

The purpose of this report is to present the methods used to collect, process, and analyze bed-material samples collected at selected sites in the Sacramento–San Joaquin Delta and to report characteristics of those samples. The characteristics presented in this paper are cumulative particle-size distribu-tions, median and 90th-percentile particle sizes (D50 and D90, respectively), and loss on ignition (LOI) data for bed-material samples. These data can be used to develop sediment transport models for the Delta and support ongoing scientific investiga-tions of sediment dynamics in the Delta.

Description of the Study Area

The study area lies within the Sacramento–San Joaquin Delta which is a triangular area generally defined by the confluence of the Sacramento and San Joaquin Rivers in the west, the Sacramento River reach near the Freeport Bridge in the north, and the San Joaquin River reach near the Mossdale Bridge in the south (Thompson, 1969). The study area and sample sites are shown in figure 1.

The hydrodynamics of the Delta are driven externally by climate, upstream dam operation, wind, and tides and internally by water diversions and a gate at the Delta Cross Channel (fig. 1). The Delta watershed has a drainage area of approximately 153,000 square kilometers (km2), which includes most of the Central Valley. Discharge in the Delta is primarily from the Sacramento and San Joaquin Riv-ers, which drain most of the north and south Central Valley area, respectively; the Mokelumne and Calaveras Rivers, which drain parts of the Sierra Nevada to the east; and a few smaller tributaries, which drain part of the eastern flank of

the Coast Ranges. Average annual discharge to the Delta is 660 cubic meters per second (m3/s) from the Sacramento River and 126 m3/s from the San Joaquin River; the maximum recorded instantaneous peak discharges are 3,300 m3/s and 2,240 m3/s, respectively (U.S. Geological Survey National Water Information System, variously dated). Climate in the Central Valley is characterized by hot, dry summers and cool, wet winters but with highly variable annual precipita-tion (Mount, 1995). In general, average annual precipitation in the low-lying areas of the Central Valley can range from 38 centimeters (cm) in the northern areas to less than 20 cm in the southern areas and, on the western slope of the Sierra Nevada, can exceed 127 cm (National Oceanic and Atmo-spheric Administration, 1985). During high-flow events on the Sacramento River, water can spill over two weirs, which serves to provide flood protection to the city of Sacramento. Water spilling over the weir enters the Yolo Bypass where it flows into the Delta at the northern end of now-flooded Liberty Island (fig. 1). The major tributary rivers are regulated by upstream dams, which maintain constant freshwater discharge during the summer (for water exports through the Clifton Court Forebay) and, to some extent, reduce peak flows during storm events that usually occur during the winter and spring. Discharge and stage data are available for most bed-material sample sites through the USGS National Water Information System (NWIS) web data server (U.S. Geological Survey National Water Information System, variously dated).

Methods

Bed-Material Sample Collection

Samples were collected from a motorized boat using US BM–54 and US BMH–60 cable-suspended, bed-material scoop samplers following standard USGS protocols for use of these samplers (Subcommittee on Sedimentation, 1958; Edwards and Glysson, 1999; Davis, 2005). At all but one site, a sample of the bed material was collected from the center of the channel and from the left and right sides of the channel (at the approximate midpoint between the channel center and the bank). One site was not in a channel (Liberty Island near Prospect Island near Rio Vista, CA, Station 381504121404001 at http://waterdata.usgs.gov/nwis/inventory/?site_no=381504121404001&agency_cd=USGS) (table 1), and at this site, only one sample of the bed material was collected. At most sites, the edge of the channel was a well-defined armored bank; however, at some sites emergent vegetation grew near the bank. At these locations, the edge of the main channel was defined as the edge of the emergent vegetation. All references to the left or right side of the river in this report refer to the perspective of an observer looking downstream. The coordinates for each sample were logged using the boat’s on-board Global Positioning System (GPS). Site information, location in the channel (expressed as percent of channel width

from left bank), date, and time were recorded for each sample. Approximate sample depth, in feet below water surface, was also recorded for most samples.

Bed-material samples were collected initially from 30 sites in the Delta, all of which are collocated with active USGS streamgages, except for the Sacramento River at Hood, CA, Station 382205121311300, which is a California Department of Water Resources streamgage (table 1). Sam-ples were collected at an additional seven sites starting in fall 2012 at locations corresponding to new streamgages or water-quality monitoring stations in the Delta. The additional sample sites are at Cache Slough at South Liberty Island near Rio Vista, CA, Station 11455315 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11455315&agency_cd=USGS), Lindsey Slough near Liberty Farms, CA, Sta-tion 3814481214208010 (http://waterdata.usgs.gov/nwis/inventory/?site_no=381448121420801&agency_cd=USGS), Liberty Island near Prospect Island near Rio Vista, CA, Station 381504121404001 (http://waterdata.usgs.gov/nwis/inventory/?site_no=381504121404001&agency_cd=USGS), Suisun Bay at Mallard Island, CA, Station 11185185 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11185185&agency_cd=USGS), North Mokelumne River near Walnut Grove, CA, Station 11336685 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11336685&agency_cd=USGS), South Mokelumne River at New Hope Bridge near Walnut Grove, CA, Station 11336680 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11336680&agency_cd=USGS), and Ulatis Creek near Elmira, CA, Station 11455268 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11455268&agency_cd=USGS). Sample sets were gen-erally collected each fall (prior to the winter‒spring flood season) and again after the winter‒spring flood season (if one or more high-flow events occurred) to document any variability in the particle-size distribution, which could have occurred as a result of the high-flow event. However, because there were no major high-flow events during winter‒spring of water years1 2012 or 2014, a second sample set was not collected later in those water years. The approximate sampling periods in relation to streamflow discharge recorded at USGS streamgages on three of the major tributaries to the Delta are shown in figure 2.

Collection of Supplemental Bed-Material Samples

Supplemental bed-material samples were collected at seven sites during the winter 2013 sampling period. Five of those sites were sampled more intensely to determine whether three samples per site were sufficient to describe bed-material composition at the site. The other two sites are near bridges, which could induce scour at the sample site; therefore, addi-tional samples were collected downstream.

1A water year is the 12-month period from October 1 to September 30. It is designated by the calendar year in which it ends.

Figure 2. Hydrograph of major tributaries in the Sacramento–San Joaquin Delta, California, with vertical lines indicating bed-material sampling periods.

The five sites selected for more intensive sampling are Sacramento River Deep Water Ship Channel near Rio Vista, CA, Station 11455335 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11455335&agency_cd=USGS), Little Potato Slough at Terminous, CA, Station 11336790 (http://waterdata.usgs.gov/ca/nwis/inventory/?site_no=11336790&agency_cd=USGS), Middle River at Middle River, CA, Station 11312676 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11312676&agency_cd=USGS), Moke-lumne River at Andrus Island near Terminous, CA, Station 11336930 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11336930&agency_cd=USGS), and Cache Slough at Ryer Island, CA, Station 11455350 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11455350&agency_cd=USGS). The supplemental samples, numbered 1–4, were collected between each primary sample location and between the bank and the nearest primary sample location, such that there were seven evenly spaced sample locations ordered 1, left, 2, center, 3, right, and 4 (fig. 3).

The results of the intensive sampling show that when the results were averaged across the channel, there was little difference between sampling at only three locations within the channel and sampling at seven locations. The site aver-ages for the 50th (median) and 90th percentiles of particle size (D50, D90) and the LOI were compared simply, by calcu-lating the averages from the typical three sample locations at each site (left, center, and right) and the averages from the seven sample locations (left, center, right, 1, 2, 3, and 4) and determining the difference between the two. The D50 differed among the five sites by 0.01‒0.03 millimeter (mm), D90 dif-fered by 0.02‒0.04 mm, and there was less than 0.5 percent difference in LOI test results.

The mass of sample material collected at two sites—North Mokelumne River near Walnut Grove, CA, Station 11336685 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11336685&agency_cd=USGS) and Sutter Slough at Courtland, CA, Station 11447830 (http://waterdata.usgs.gov/nwis/inventory/?site_no=11447830&agency_cd=USGS)—was sometimes insufficient to process and analyze. A small sample quantity will often occur if the sampler encounters either a bed composed of hard-pan clay or material that is too large for the scoop. Because both of these sites were adjacent to bridges, it is possible that bridge-induced scour prevented accumula-tion of bed material at the sample locations and that the bed composition at the sample location differed from that found downstream. Therefore, during the winter 2013 bed-material sample collection, additional bed-material samples were col-lected about 90–120 meters downstream from the streamgage at those two sample sites.

Sampling downstream from the original North Moke-lumne River site resulted in samples with generally greater mass than those collected at the original site. At the original site during the winter 2013 sampling period, the sampler failed to collect any bed material at the sample location on the right side of the channel, and the sample mass collected at the remaining two locations was only about 4 grams (g). At


the downstream North Mokelumne River site, samples were collected at all three channel locations; however, the mass col-lected from the left side of the channel was small (only about 13 g). At the original Sutter Slough site, bed material was collected at all three channel locations, but the sample mass from the left channel location was small (about 17 g). At the downstream Sutter Slough site, the sample mass of each addi-tional channel location was very similar to that of the original site, and the mass of the sample collected at the left channel location was small. Thus, sampling downstream from the original Sutter Slough sample site did not result in an increase in the volume of sample material obtained. The results from those two sites are best used with caution for any of the six sample sets, particularly if the quantity of the sample material is small. None of the collected samples were excluded from the resulting dataset used for this report.

Sample Preparation

Bed-material samples were first dried in an oven at 105 degrees Celsius. After samples were dried and cooled to room temperature, clumps of sediment were disaggregated using a mortar and pestle. Mollusk shells (which were often found in samples) were removed, and the total mass of sedi-ment in each sample was recorded. The average mass of sedi-ment samples after shell removal was 155 g. Samples were then split into subsamples using a Quantachrome Instruments Sieving Riffler™ (Riffler). Sample material was poured into

a 2-mm sieve mounted directly above the Riffler’s cylindrical hopper. If coarse material (greater than 2 mm) was present, it was weighed and set aside for further evaluation (see section “Samples Containing Coarse Material” for a detailed explana-tion). The Riffler was used to split each sample into eight well-mixed subsamples. Large samples were often split a second time to reduce the size of the subsample. After a subsample of adequate size (generally 2–10 g) was obtained, it was placed in a ceramic saucer and wetted with a solution containing 5 percent sodium hexametaphosphate to deflocculate clay par-ticles. Two to three subsamples were treated with the defloc-culating solution prior to processing (as explained in the next section). One additional subsample from each sample was set aside for LOI analysis. The subsample used for LOI analysis was not treated with deflocculating solution.

Particle-Size Distribution Analysis

The primary instrument used to measure the particle-size distribution of bed-material samples was a Beckman Coulter LS™ 13–320 Laser Diffraction Particle Size Analyzer (analyzer) with an Aqueous Liquid Module. The steps used for the particle-size distribution analysis are described briefly here and then explained in further detail in the following subsections. First, two subsamples were processed, and the results were compared to determine whether a third subsample was needed. Results of the analyzed subsamples were then averaged. The analyzer is limited to processing material finer

than 2 mm. Therefore, if coarser material was present in the original sample, it was sieved and measured separately. The results of the sieving (for the coarse material) were then com-bined with the analyzer data. In addition to processing samples using the analyzer, one sample set was processed using both the standard sieving method and the analyzer. A comparison of these results is provided in subsequent sections along with an explanation of the limitations of the sieving method and the rationale for using the analyzer to process all remaining samples.

Comparison of Sieving and Analyzer MethodsThe first set of bed-material samples was processed using

the standard wet-sieving method (Guy, 1969), which uses wire-mesh square-hole sieves, and also using the analyzer. For sieved samples, the fraction of particles finer than 0.063 mm, 0.125 mm, 0.25 mm, 0.5 mm, 1 mm, and 2 mm were weighed and recorded. The analyzer measures the percent volume of particles for 96 size classes between 0.000375 mm and 2 mm.

The D50 was calculated using linear interpolation between the nearest sieve sizes or between the nearest size classes recorded by the analyzer. The D50 and silt/clay fraction (finer than 0.0625 mm) for both methods are plotted in figure 4A and 4B. The precision of the wire-mesh sieve is limited to 0.001 mm; therefore, for the silt/clay fraction (typically considered finer than 0.0625 mm), the results for fraction of particles finer than the 0.063-mm sieve were used. The D50 could not be calcu-lated using the sieve results for 16 samples because more than one-half of the particles were finer than the smallest sieve size (0.063 mm); therefore, these data could not be shown on figure 4B. In addition, one of the original samples was lost (therefore was not processed with the analyzer), and the original sieving notes for a different sample were lost, so the comparisons of results for these two samples are not shown in figure 4A and 4B (data provided in appendix 1, table 1-1). The number of samples shown in figure 4A and 4C is 88, and the number of samples shown in figure 4B and 4D is 72. Residu-als from the line of equivalence were also calculated and are shown in figure 4C and 4D.

Median particle size using thesieve method, in millimeters

Portion of sample finer than 0.0625 millimeterusing the sieve method, in percent


A visual inspection and statistical test show that the two datasets shown in figure 4A and 4C were correlated. Visual inspection of the plots in figure 4A and 4C reveals that the portion of sediment finer than sand measured using the sieving method and the analyzer method is generally linearly corre-lated. The visual appearance of correlation strength also agrees with calculations of the Pearson’s r coefficients, which were 0.92 and 0.88 for figure 4A and 4B, respectively.

The residuals were also calculated for the two datasets and are shown in figure 4C and 4D. The probability plot correlation coefficient test (Looney and Gulledge, 1985) was used to check if the residuals were normally distributed. The r value calculated in this test was 0.93 for the portion finer than 0.0625 millimeter dataset (fig. 4A) and 0.87 for the median grain size dataset (fig. 4D). Neither value exceeded the r critical value for α=0.05 (table B3 in Helsel and Hirsch, 2002), indicating that they were not normally distributed. For non-normal distributions, a nonparametric test—the signed-rank test (Wilcoxon, 1945)—was used to check for differences between the sieve and analyzer data in each dataset.

The Wilcoxon signed-rank test was used to test for differences between the sieve data and the analyzer data for both the median grain-size dataset (fig. 4B) and the portion finer than 0.0625 millimeter dataset (fig. 4A). The p-values calculated from the Wilcoxon signed rank test were 0.00002 and 0.040 for the median grain size and portion finer than 0.0625 millimeter datasets, respectively (fig. 4B and 4A).

A linear regression equation was also calculated for the two residual datasets (that is, the data plotted in fig. 4C and 4D). The slope coefficients calculated from linear regression for these datasets were –0.22 and –0.28 (for the median dataset and the silt/clay fraction dataset, respectively). This indicates there was negative bias for the finer samples and there was a slightly positive, possibly negligible, bias for the coarser samples.

The sieves and the analyzer measured sample percentages finer than 0.063 mm, whereas the samples’ D50 was calculated through linear interpolation between sieve sizes or analyzer bin sizes. Therefore, a greater number of sieves or analyzer bins will improve the approximation of the D50. The sieving method provided only 5 size classes; the analyzer method provided 96 size classes.

The analyzer method was the preferred method for calcu-lating particle-size distribution because of the greater number of size classes and because size classes are much smaller than those of the sieving method. As indicated above, it was not possible to calculate the D50 using the sieving method for samples when more than one-half of the particles were finer than the 0.063-mm sieve (the smallest sieve size). Owing to these limitations, the sieving method was not used for other sample sets. The results from the sieve analysis are provided in appendix 1 of this report.

Particle-Size Distribution Using the Analyzer

Subsamples of bed material for all sample sets were pro-cessed using the analyzer. This instrument is limited, however, in its ability to accurately analyze particles with a nominal diameter greater than 2 mm (Beckman Coulter Inc., 2009). If such coarse material was present in any sample, it was sieved during sample preparation and weighed separately using sieves ranging from 2 mm to 32 mm (no samples contained particles larger than 32 mm). The analyzer measures the percent volume of particles for 96 size classes ranging from 0.000375 to 2 mm. The D50 and D90 were calculated using linear interpo-lation between the nearest size classes. The analyzer used the Fraunhofer Model to estimate particle size on the basis of the measurements of light diffraction. Size classes for 0.004 mm, 0.008 mm, 0.016 mm, 0.0313 mm, 0.0625 mm, 0.125 mm, 0.25 mm, 0.5 mm, 1 mm, and 2 mm (corresponding to 1 phi increments) were interpolated between the nearest size classes recorded by the analyzer. For samples containing particles larger than 2 mm, the percent by mass of particles larger than 2 mm was used to recalculate the particle-size distribution, and D50 and D90. Details on this procedure are described later in the section “Samples containing coarse material.”

Replicate Analyzer MeasurementsTo assure that subsamples were well mixed during

splitting (and thus representative of the original sample), the selected subsamples were processed, and the D50 of each subsample was compared to the original and (or) to the previ-ous subsample by calculating the relative standard deviation (RSD). The RSD is calculated by dividing the standard devia-tion of the subsamples’ D50 (S) by the mean of the subsamples’ D50 (X) using equation 1.

RSD S

X= 100

(1)

If RSD for a pair of subsamples was less than 10 percent, the particle-size distribution results for the two initially selected subsamples were averaged for each of the 96 size classes. If the RSD was 10 percent or greater and the abso-lute difference was greater than 0.05 mm, a third subsample (triplicate) was processed. The particle-size distribution results of all three subsamples were averaged unless the D50 of one subsample deviated substantially from the D50 of the other two subsamples; in which case, the results of that subsample were discarded and the results of the remaining two subsamples were averaged. Using these criteria, additional subsamples were needed in about 5 percent of all cases.

Samples Containing Coarse MaterialSamples containing coarse material (greater than 2 mm)

required separate measurement because the analyzer is limited to measuring only particles up to 2 mm in size. Particles between 2 mm and 19 mm were dry sieved in a Ro-Tap® sieve shaker using the standard sieving method (Guy, 1969). Particles larger than 19 mm were measured by hand using an SAH–97 Hand-Held Particle Size Analyzer (Potyondy and Bunte, 2002). The analyzer method particle-size distribution, along with sieved (2–19 mm) and hand-measured portions (19–32 mm), were combined to recalculate the full-range particle-size distribution. The particle-size distribution output from the analyzer is in the form of volumetric percentage of each size class. To obtain the gravimetric distribution, the volumetric particle-size distribution was multiplied by the mass of the sample portion that was finer than 2 mm, as shown in the following equation:

M Vp Vp m mmm mm mm mm mm<( ) …[ ]= …[ ]2 0 000375 2 0 000375 2. . (2)

where

M<2 mm represents the mass of that portion of a sample finer than 2 mm;

VP represents the percent volume for each size class, as measured by the analyzer; and

m represents the mass of the particles for each size class (subscripts of VP and m denote the upper limit of the size class).

The calculated values of mass for the particles finer than 2 mm were combined with all measurements of mass in the sieved and hand-measured portions (2 mm and coarser) to calculate the full-range particle-size distribution.

Loss on Ignition

The LOI method (Heiri and others, 2001) was used on one subsample from each sample to determine the fraction of organic material. The samples were heated to 550 degrees Celsius for 4 hours (Heiri and others, 2001) and then weighed; this weight was then subtracted from the initial weight. The difference between the two weights is the weight of organic material. Next, the weight of the organic material was divided by the initial weight and multiplied by 100 to obtain the percentage of organic material in the subsample. The mass of material combusted during heating is assumed to equal the amount of organic material that was initially present in the

subsample (Heiri and others, 2001). In this study only one sub-sample from each sample was tested using the LOI method. The uncertainty of the LOI results were not measured for this study.

Results For each of the 37 sample sites, the sample-location iden-

tifier, California Data Exchange Center (CDEC) code, nearest USGS streamgage site name and identification, and GPS coordinates of sample locations are presented in table 1. The sample-location identifier for each sample is a combination of the CDEC code of the site and a letter designating the location in the channel (L, left; C, center; R, right). If a CDEC code did not exist for a site, an alternative three-letter abbreviation was used, and in some cases appending a single digit as neces-sary for uniqueness. Coordinates of the sample locations are referenced to the North American Datum of 1983 (NAD 83) geodetic reference system and are provided as latitude and longitude, in decimal degrees, and as eastings and northings, in meters (using the Universal Transverse Mercator) coordi-nate system in Zone 10 North).

Particle-size distribution results for the six sample sets are presented in tables 2–13. Tables 2–7 contain particle char-acteristic and other information, including (1) date and time of collection, (2) approximate water depth at sample locations, (3) total sample mass, D50, D90, site-average D50, site-average D90, LOI subsample mass, LOI as a percentage of total mass, and site-average LOI. Tables 8–13 contain the cumulative particle-size distribution data for the full range of particle sizes observed, reported as the fractions of sediment finer than 0.004 mm, 0.008 mm, 0.016 mm, 0.0313 mm, 0.0625 mm, 0.125 mm, 0.25 mm, 0.5 mm, 1 mm, 2 mm, 2.8 mm, 4 mm, 4.75 mm, 5.6 mm, 8 mm, 9.5 mm, 11.2 mm, 16 mm, 19 mm, 22.4 mm, and 32 mm. The size classes for sand, silt, and clay, which are the classes 2 mm and finer, were based on 1 phi increments. The larger-size classes listed above correspond to the original sieve sizes used after the first sample set. Over time, other sieves were added or removed. A map showing the spatial distribution of average D50 for the study period (2010–13) at each site is shown in figure 5.

Cumulative particle-size distributions for selected sites are plotted in figure 6A–F using results from the fall 2012 sample set. For each of these sites, the cumulative particle-size distribution for samples collected in the center, left, and right is plotted, as well as the site average cumulative particle-size distribution.
