2. THE MODEL ~ Study Area Supplied by Guleid A. Artan of the USGS
Data for the Limpopo basin in Mozambique
Map Source:

3. Rainfall/Runoff Simulation
To bin32

4. Rainfall/Runoff Simulation con’t

5. Parameters

6. GIS-Based FEWS SF MODEL

7. Complete Terrain Analysis Option:
FEWS SF MODEL ~ Option 1
Complete Terrain Analysis Option:
INPUT: Hydro1K grids
OUTPUT: basins, downstream, flowlength, hilllength, outlets, streams, strlinks grids

8. HYDRO 1K Elevation Derivative Database

9. DATA PREPARATION
Project ESRI map data into Lambert Azimuthal Equal Area
Clip grids to buffered Mozambique polygon

10. FEWS SF MODEL Watershed Delineation

11. Work to be done… Generate Basins Characteristics File Command
Requires a CN grid, Soil Water Holding Capacity Grid, Soil Depth Grid, Soil Texture Grid, Hydraulic Conductivity Grid and Max. Impervious Cover Grid
Generate Basin Response File Command
Requires Velocity Coefficient Grid
