Surface evaporation is calculated per cell.
- Δw = min( WLsurface , Δt * Eweather * Eoverlay )
where:
- Δw = The amount of evaporation which takes place.
- Δt = Computational timestep.
- Wsurface = The amount of water (the water column) on the surface.
- Eweather = The evaporation rate of the weather.
- Eoverlay = The SURFACE_WATER_EVAPORATION_FACTOR.
