Metadata

Also known as
Model type Single
Model part of larger framework LandLab
Incorporated models or components:
Spatial dimensions 2D
Spatial extent Regional-Scale, Landscape-Scale, Watershed-Scale
Model domain Terrestrial, Hydrology
One-line model description Compute the decay of soil moisture saturation at storm-interstorm time period
Extended model description Landlab component that simulates root-zone average soil moisture at each cell using inputs of potential evapotranspiration, live leaf area index, and vegetation cover.

This component uses a single soil moisture layer and models soil moisture loss through transpiration by plants, evaporation by bare soil, and leakage. The solution of water balance is based on Laio et. al 2001. The component requires fields of initial soil moisture, rainfall input (if any), time to the next storm and potential transpiration.
