1 Meredith Shiflet

2 Outline Watershed mapping Structure Design Irrigation Water management Erosion modeling

3 Watershed Mapping Foundation for water management decisions Getting Data - Arc GIS Easy way….OR…Hard way

4 Watershed Mapping Arc GIS Boundary mapping Elevation, contours Flow length State/Storage Soil mapping Handheld GPS units SO MANY MORE!

5 Watershed Mapping Hydrologic Engineering Centers River Analysis System (HEC- RAS)

6 Watershed Mapping AutoCAD- Civil 3 D

7 Structure Design WinDam Large flood control structure design Over 11,000 watershed dams in 47 states (many exceeding design life) WinPond Small flood control structure design (Ponds, Grade Control Structures)

8 Irrigation Water Management CPED Center Pivot Evaluation and Design Evaluate performance of a center pivot design Models water distribution under a center pivot from various commercial nozzles CPNOZZLE Estimate runoff potential of a sprinkler package

9 Irrigation Water Management DRAINMOD Simulates hydrologic characteristics of poorly drained soils and analyzes the effectiveness of subsurface drainage systems SPAW Soil-Plant-Air-Water Balance Uses NRCS Curve Number Method

10 Erosion Modeling RUSLE 2 Predicts rill and sheet erosion by rainfall runoff Cannot estimate erosion in highly concentrated flow Primary NRCS water erosion tool

11 Erosion Modeling WEPP Water Erosion Prediction Project applicable sheet and rill erosion, as well as simulation of the hydrologic and erosion processes on small watersheds WEPS Wind Erosion Prediction System Replaces the Wind Erosion Equation
