  1. Water Management Tools 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 3D

  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
