Watershed depiction and information arrangement for groundwater demonstrating utilizing GIS in the Savannah River Site GIS term extend presentation November 25, 2003 Prepared by Jaehak Jeong

Slide 2

Outline Introduction Objective Data portrayal Watershed Delineation Infiltration rate Conclusion Future work

Slide 3

Objective To display the surface water hydrology by depicting the watershed To develop the penetration lattice which speaks to the topology and the topography for groundwater displaying To get amicable with the ArcGIS

Site depiction Located at the outskirt of SC and GA Occupies 310 square miles. (about the extent of the Washington, D.C. expressway) Constructed amid the mid 1950s to create the essential materials for atomic weapons (principally tritium and plutonium-239) Included on the National Priorities List (NPL) in 1989. Old Radioactive Waste Burial Ground (ORWGB) is distinguished as a RCRA/CERCLA unit

Slide 5

GIS Data Digital Elevation Model (DEM) Downloaded from the "seamless.usgs", EROS Data Center Grid cell measure = 30m National Hydrography Dataset (NHD) Stream arrange, downloaded from the USGS Statsgo - State Soil Database (1:250,000 scale), USDA Contains soil properties and soil translations for building, water administration, and so on and untamed life employments of the dirt. Hydrologic soil bunches (A,B,C and D) Land Use/Land Cover (LULC) information, EPA 9 classifications of significant land utilize sorts.

Slide 6

Data Preparation DEM quadrangles were converged into one. ( from "52" to "1" ) Merged DEM was veiled onto the 1Km cushioned limit scope. NHD, Statsgo, LandUse information were cut on the 1Km cushioned limit scope. Projection : UTM Zone 17 Datum : North American Datum 1983 Units : meters

Infiltration rate estimation Runoff at the Site No.7 at SRS Fac : 36,087 cells => 3.5 * 10 8 ft 2 Precipitation at CLARK HILL 1 W, SC Pan Evaporation rate - 50 in/yr Infiltration rate ( Precipitation – Runoff – Evaporation ) = 47 in/yr - 0.174 * 47 in/yr - 0.7 * 50 = 3.8 in/yr
