This component has been tested on the reach and watershed scale (<= 100 km^2), but can likely run effectively on even larger scales as needed. +
After infiltration occurs, the component returns an updated 'surface_water__depth' field, as well as an updated 'soil_water_infiltration__depth' field that tracks how much water has been infiltrated into the soil column. +
Soil infiltration, as calculated using the Green-Ampt equation. +
The component has been tested on event to annual time scales, on a range of resolutions (1 m to 100 m) but would likely run efficiently on even longer time scales and finer resolutions). +
As is, no updates are provided +
For each time step, this component calculates an infiltration rate for a given model location and updates surface water depths. Based on the Green-Ampt method, it follows the form of Julien et al., 1995. +
