What is it?
Soils affect overland flow through how water infiltrates into, or evaporates from the ground surface. For example, water easily seeps into sands and gravels (high hydraulic conductivity, low initial runoff), while it may run over clays (low hydraulic conductivity, high initial runoff).How to use it:
To specify soil types for overland flow in the current model zone check the box next to "Soil Type" and set the parameter values. Soil parameters can be assigned to constant values, or using a lookup table they can be derived from a raster dataset (either from the IGW-NET server, or loaded by a user). If a raster from the Data Center is used (this is the default), click "Lookup Table" to open the Soil lookup table. By default lookup values are pulled from the USDA Soil Classification Guide .If the user uploads their own raster and it is not formatted as a IGW-NET raster, the "Non-IGW-NET Format" option must be selected.
