No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? No If above answer is yes Other visualization software Describe processes represented by the model This model is designed to represent infiltration (Green-Ampt), rainfall interception, and runoff (kinematic wave). Hydraulic roughness is accounted for using a depth-dependent Manning-type flow resistance equation.
