Subject: Large-scale Slope Testing of EarthGuard® Fiber Matrix HECP over Sandy Loam

Dear Mr. Dabbs:

This letter report presents the results for large-scale slope erosion tests performed on

EarthGuard® Fiber Matrix hydraulically-applied erosion control product (HECP) over sandy

loam. All testing work was performed in general accordance with the ASTM D 6459, Standard

Test Method for Determination of Rolled Erosion Control Product (RECP) Performance in

Protecting Hillslopes from Rainfall-Induced Erosion modified as necessary to accommodate

hydraulically-applied mulch. The product was allowed to cure on the slopes for approximately

48 hours prior to testing. Generated results were used to develop the following general cover

factor (C-Factor) for the tested material:

C-Factor EarthGuard® Fiber Matrix HECP@ 3000lbs/acre = 0.001 for cumulative R-Factor < 162

Eqn: C = 0.001 (Upper threshold value at all R-Factors)

TRI is pleased to present this final report. Please feel free to call if we can answer any questions

or provide any additional information.

Sincerely,

C. Joel Sprague, P.E.

SLOPE TESTING REPORT

EarthGuard® Fiber Matrix HECP over Sandy Loam TESTING EQUIPMENT AND PROCEDURES

Overview of Test and Apparatus

TRI/Environmental, Inc.'s (TRI's) large-scale slope erosion testing facility is located at the

Denver Downs Research Farm in Anderson, SC. Testing oversight is provided by C. Joel

Sprague, P.E. The large-scale testing reported herein was performed in accordance with ASTM

D 6459 modified as necessary to accommodate hydraulically-applied mulch, on 3:1 slopes using

loamy soil test plots measuring 40 ft long x 8 ft wide. The simulated rainfall was produced by ten

“rain trees” arranged around the perimeter of each test slope. Each rain tree has four sprinkler

heads atop a 15 ft riser pipe. The rainfall system has been calibrated prior to testing to determine

the number of sprinkler heads and associated pressure settings necessary to achieve target

rainfall intensities and drop sizes. The target rainfall intensities are 2, 4, and 6 in/hr and are

applied in sequence for 20 minutes each. Three replicate test slopes covered by the same

hydraulically-applied erosion control product (HECP) submitted were tested. The application

rate of the HECP was 3000 lb/acre. (Note: The mixing ratio was 65 gallons of water to 50 lb

mulch.) The product was allowed to cure on the slopes for approximately 48 hours prior to

testing. The erosion resistance provided by the product tested is obtained by comparing the

protected slope results to control (bare soil) results. Tables and graphs of rainfall versus soil loss

are generated from the accumulated data.

Preparation of the Test Slopes

The initial slope soil veneer (12-inch thick minimum) is placed and compacted. Compaction is

verified to be 90% (± 3%) of Proctor Standard density using ASTM D 2937 (drive-cylinder

method). Subsequently, the test slopes undergo a “standard” preparation procedure prior to each

slope test. First, any rills or depressions resulting from previous testing are filled in with test soil

and subject to heavy compaction. The entire test plot is then tilled to a depth not less than four

inches. The test slope is then raked to create a slope that is smooth both side-to-side and top-to-

bottom. Finally, a steel drum roller is rolled down-and-up the slope 3 times proceeding from one

side of the plot to the other. The submitted erosion control product is then installed using the

spray technique acceptable to the client. For this testing, TRI applied the product to the slopes.

Installation of Erosion Control Product on Test Slopes

As noted, the submitted erosion control product was installed as directed by the client. For the

tests reported herein, the HECP was mixed at a rate of 50 lbs mulch per 65 gallons of water and

applied at the rate of 3000 lb/acre. The applied material was allowed to cure for approximately

48 hours prior to testing.

Specific Test Procedure

Immediately prior to testing, rain gauges are placed at the quarter points (i.e. 10, 20, 30 ft) on the

slope. The slope is then exposed to sequential 20-minute rainfalls having target intensities of 2,

4, and 6 inches per hour. All runoff is collected during the testing. Additionally, periodic

sediment concentration grab samples are taken and runoff rate measurements are made. Between

rainfall intensities, the rainfall is stopped and rainfall depth is read in the three rain gauges,

valves are adjusted to facilitate the subsequent rainfall intensity, and empty collection vessels are

positioned to collect subsequent runoff. After allowing for sediments to settle, water is decanted

from the collected runoff. The remaining solids are used to determine “bulk” soil loss. Bulk soil

loss is measured by drying all collected sediments.

TEST RESULTS The Cover Management (C) Factor from the Revised Universal Soil Loss Equation (RUSLE) of the

USDA-ARS Agricultural handbook 703 is the reported performance measure for slopes determined

from this testing. The C-Factor and R-Factor reported herein are related through RUSLE by the

following relationship:

A = R x K x LS x C x P

where: A = the computed soil loss in tons per acre (measured/calculated from test);

R = the rainfall erosion index (measured/calculated from test);

K = the erodibility of the soil (calculated from test – see Figure 9);

LS = the topographic factor (2.78 for 8 x 40 ft slope);

C = the cover factor = ratio of protect soil loss to control soil loss (1.0 for control); and

P = the practice factor (1.0 for all test slopes).

Total soil loss and the associated rainfall depth measured during the testing are the principle data

used to determine the C Factor. The cumulative C-Factors shown in Table 3 are the ratio of the soil

loss from the protected condition at a calculated cumulative R-Factor divided by the cumulative soil

loss from the control plot (Figure 9) at that same R-Factor.

In all cases, the soil loss and associated rainfall data for both protected and control conditions are

used to develop a graph of cumulative R-Factor versus C-Factor (R factor = total kinetic energy of

the storm (E) times its maximum 30-minute Intensity (I)). The theoretical cumulative R-Factor

calculated for the target test events: 2 in/hr for 20 minutes + 4 in/hr for 20 minutes + 6 in/hr for 20

minutes, is R = 231 assuming all raindrops achieve terminal velocity. Since this is not the case, the

R-Factor must be normalized to reflect the kinetic energy associated with the actual velocity

achieved by each size of raindrop. For the tests reported herein, the C-Factor associated with this

normalized R-Factor of 162 is the reported performance value. This facilitates product-to-product

comparison of test results at a common point of the storm event.

Graphs of R-Factor versus C-Factor for the protected condition and Soil Loss versus R-Factor for

the control condition are shown in Figures 8 and 9, respectively. Figure 8 includes the best

regression line fit to the test data to facilitate the determination of the C-factor. Figure 8

additionally allows users of this report to evaluate performance at other points in the model storm

by selecting the R factor (and the corresponding C Factor) that may fit local conditions.

According to the test procedure ASTM D6459, a test may be stopped in the event of catastrophic

soil loss, as determined by the lab. AASHTO NTPEP ECP Panel has determined this practice

places an undue amount of subjectivity into the test. In lieu of stopping the test, the test is run to

completion. The runoff and sediment loss just prior to a catastrophic failure is separated from that

occurring after. This additional point is used in the creating of the Soil Loss verses R Factor Graph.

The tests reported herein did not experience sudden (i.e. catastrophic) soil loss occurrence. Linear

(R2

< 0.1), power (R2

< 0.1), exponential (R2

< 0.1), and polynomial (R2 < 0.1) fits were evaluated.

Since all were poor fits, an upper threshold approach was used.

The overall C-Factor information shown in Table 4 is derived from Figure 8 which relates the C-

Factors and associated R-Factors given in Table 3.
