Like land use, soil type coverages/grids can be used to map model parameters. Tables with corresponding runoff coefficients, Green & Ampt parameters, or CASC2D values for different can be mapped. The CASC2D tables are the same as defined in the land use section. Runoff coefficient table definitions and examples are given in Figure 1 and Figure 2.

Green & Ampt mapping file definitions and an example are given in Figure 3 and Figure 4.
