Account Number: 20-5708-86 1 Collaborators: Gordon Wittmeyer

Objective: transport and dilution.

Develop a groundwater flow model for Yucca Mountain region to study radionuclides

4/22/97 Model Selection:

After carefully reviewing various commercial software (Groundwater Vistas, Visual Modflow, Processing Modflow, and Modflow Win32) Groundwater Modeling System (GMS) was selected as the user interface for the modeling. The GMS is developed by BYU for DOD and is a very widely used interface for MODFLOW, MODPATH, and MT3D models. The demo version of the software was downloaded from the website and after satisfactory review it was requisitioned through purchase order no. 40367 on 4/18/97.

The GMS was licensed on 4/21/97. The current password which expires on 10/97 is given below. (The expiring password was requested for easier migration to Sun Solaris System.)

1. The ECGL will ship GMS 2.1 reference and tutorial manuals, as well as manuals for MODFLOW I & 11, MT3D, and MODPATH when GMS 2.1 is released, anticipated for July 1997.

2. With the reference manuals ECGL will ship a Sunsolaris 8mm tape.

4/28/97 Methodology:

The preliminary model grid is bounded by following UTM coordinates. east-west: 530000-56oooO north-south: 4030000-4090000

The preliminary grid will consists of 16 rows, 32 columns, and 3 layers. This grid will be refined after the conceptual model is complete. The groundwater flow will be modeled by MODFLOW and the redionuclide transport will be modeled by MT3D.

The conceptual groundwater flow model will be based on hydrogeologic data from regional models developed by IT Geotrans and USGS.

5120197 The preliminary model grid is not attaining steady state heads similar to regional model. The input file as provided by USGS are not reproducing the results published in the draft report. Discussions with Frank D’Agnese and Mary Hill clarified this discrepancy. Frank suggested to recreate the files to produce results submitted in the draft version of the report.

. .

5/23/97 The input files were created to reproduce the results. The regional model simulation were utilized for pathline model MODPATH. Preliminary results will be discussed with NRC on the upcoming meeting next week in NRC Headquarters.

Amit Armstrong Scientific Notebook No. 214 Printed on:June 6, 1997

6/4/97 The regional model was used to simulate pathline under different pumping scenario as discussed during the meeting at NRC. Based on these results, model will be discretized for the smaller domain with finer grid spacing as the current grid spacing is not fine enough for a accurate representation of pathline capture.

71151199 Using Unsupervised Classification of SPOT HRVIR Scenes to Establish Ground Cover Types in the Reveille Range, Nevada

Goal: Determine ground cover types in Reveille Range and environs in order to monitor Bromus infestation through the since may 1988.

Collaborators: Dr. Michael Conway (Consultant), Arizona Western College Dr. David Groeneveld (Consultant)

Data Resources: SPOT xS: 3 July 1998,31 May 1988 Landsat MSS Scenes HAP-83 black & white aerial photos of the Reveille Range

(sequence 74- 124 through - 13 1 loaned by Britt Hill)

Data Processing

Data processing of satellite images was minimized to facilitate classification analysis. However, to facilitate other types of analysis, fundamental image processing (histogram equalization) was performed on the SPOT images. (The algorithm for this process is provided in the ERDAS- IMAGINE manual).

Method & Results

Geocoded SPOT imagery was used to conduct ground cover classification experiments of the Reveille Valley situated between the Kawich and Reveille Ranges (Fig. 1). a reasonable classification system, unsupervised ISODATA (iterative self-organizing data analysis) classification experiments of 6, 8, and 12 ground cover classes, respectively, were tested. Classifications experiments were performed on two-band subsets of the July 98 and May 88 SPOT images; subsets were of the northern and central Reveille Valley. The bands used in this analysis were band 2 (red: 0.61 - 0.68 um) and band 3 (near-infrared: 0.79 - 0.89). Band 1 (green: 0.5 - 0.59) was ignored because it does not generally provide insight into vegetation analysis.

In order to establish

In this preliminary analysis it quickly became apparent that a classification system consisting of six classes was preferred over systems with either eight or 12 classes, respectfully. Increasing the number of classes beyond six resulted in minor, and at this phase of the project, unimportant subdivisions of the six major classes. The larger class-number experiments could, however, provide insight into peripheral subclasses and should be a component of future ground-truthing work.

Page 1-8

Am i t Arm stron g Scientific Notebook No. 214 Printed on: October 29. 1999

Results of the unsupervised classification are shown in Fig. 2A, 2B, and 3 (z:Wx-revill-4~ 1 ss-2bnd-unckimg and 4x l~revill~ss2bnd~uncls.img). Unsupervised classification provided results that were readily interpreted when examined in conjunction with oblique, color aerial photos (scale undetermined), black & white aerial photos (1:80,000), and the processed SPOT images. Interpretation of the six major ground cover classes are described in some detail below.

Six Ground Cover Classes: The six ground cover classes established in unsupervised classification experiments and arranged in order of increasing brightness are:

Basaltic lava flows -- This is the ground cover class with the lowest digital values. The general accuracy of this interpretation is confirmed by black & white aerial photographs of the Reveille Valley.

Rock outcrop and debris -- this ground cover type is areally restricted to the Kawich and Reveille Ranges. The spectral signal is apparently the result of reflectance from exposures of bedrock surfaces and rock debris.

Bromus & other vegetation -- The area identified as Bromus is areally restricted to bajadas on the east side of Reveille Valley adjacent to the Reveille Range. Identifying this ground cover class as Bromus is problematic. In all likelihood, the spectral signature is a mixture of reflection from vegetation (Bromus?) and weakly developed soils.

Drainages -- These are long, narrow areas that extend the Reveille and Kawich Range fronts to the valley floor. The spectral signal probably reflects the presence of vegetation that envelops these ephemeral streams.

Recently active Fan surface -- areas with intermediate brightness values that surround areas with particularly high brightness values. I interpret the former as part of the fan surface that is relatively inactive.

Inactive Fan Surface -- Particularly effective reflectors in the green, red, and near infrared are interpreted as inactive fan surface. High reflectance is probably caused by ubiquitous desert varnish (manganese-based stain) on rock surfaces in these portions of the fan.

Comment on SPOT Images

The later SPOT image (3 July 98) shows distinct diagonal bands. Digital numbers from pixels immediately adjacent to one another on either side of these distinct bands are similar. Nonetheless, the banding impacts on the classification process and produces discrete thin diagonal bands in the classification output. This banding is most evident in the fan surface at the west foot of the Reveille Range. Radiometric techniques could be used to removed banding from the original data. However, this would result in changes in the digital numbers (i.e. pixel values)

and would preclude comparison with earlier data sets.

I suggest requesting SPOT to remit a replacement data set. Ideally, the replacement data would be from a period in late-May to early-June to complement the comparative data set collected on 3 1 May 1988. If a replacement data set is unavailable, SPOT should make efforts to correct radiometric anomalies within the 3 July 98 digital data.

Future Work

The validity of any unsupervised classification rests wholly on systematic ground-truthing of the classification experiments. Thus, in order to validate these classification experiments it is necessary to visit the Reveille Valley and examine material making up the valley floor and surrounding ranges. While this ground-truthing will provide insight into the veracity of the unsupervised classification, it will not in and of itself assist with a more robust supervised classification, which requires a-priori knowledge of the spectral signature of ground cover classes. I strongly suggest that ground-truthing should involve collecting spectral data from ground cover materials. This will require use of a field spectrometer that samples in the red, near- and mid-IR spectral range.

Listed below are a series of tasks that should accompany ground-truthing in the Reveille Range area.

Tasks

0 Request action from SPOT on radiometric banding of 3 July 98 image

0 Obtain either DEM, DLG or DTED data for the Reveille Range

0 Rectify MSS images (Not particularly necessary for work in Reveille Range area).

0 Check USGS for high resolution (1 :40,000 to 1 :80,000) color or IR images

0 Investigate potential of adding 1 st derivative (slope) and 2nd derivative (aspect) to classification analysis.

0 Obtain geologic maps and soil classification maps for Reveille Valley Select multiple training areas for the six ground cover classes and note their UTM coordinates

Conduct ground truthing of the classification system

Obtain spectral signatures on ground cover types

0 Determine density of Brornus grasses in training area
