The soilwat model simulates the flow of water through a plant canopy and soil layers. Rainfall interception, infiltration of water into soil, rapid and slow soil water drainage, and evaporation of water from the plant canopy and the soil layers are simulated on a daily timestep. The model can treat an arbitrary number of soil layers in each of which depth and soil type are specified.
