This model is in development for use in the NGen Water Modeling Framework Prototype. It includes wrapper functions for the Basic Model Interface. More BMI related references can be found here.

TOPMODEL is a physically based, distributed watershed model that simulates hydrologic fluxes of water (infiltration-excess overland flow, saturation overland flow, infiltration, exfiltration, subsurface flow, evapotranspiration, and channel routing) through a watershed. The model simulates explicit groundwater/surface water interactions by predicting the movement of the water table, which determines where saturated land-surface areas develop and have the potential to produce saturation overland flow. TOPMODEL was originally developed by Beven & Kirby (1979).
