🌧️ Hillslope Storm Runoff Lab: Green-Ampt Infiltration, Manning Sheet Flow and the Hydrograph

Rain a storm onto a 3D cut-away hillslope and watch the soil soak up what it can while the rest runs downhill as a sheet of water; change soil, cover, slope and intensity and read the hydrograph, the runoff coefficient and the time of concentration against closed-form solutions.
