WebUnder the con- dition of rainfall, the overland flow is the main power for the soil erosion on the slope with the three- dimensional Geomat, which causes the soil detach- ment and the silt deposition. The overland flow is a shallow open flow, with its flux formed by the rainfall and deduced by the surface retention and infiltration. WebOverland flow is surface runoff that occurs in the form of sheet flow on the land surface without concentrating in clearly defined channels. This type of flow is the first …

WebNov 18, 2013 · Shallow Concentrated Flow - Lsc Now that we know the travel time for the overland flow, we need to calculate the travel time for the shallow concentrated flow … WebMar 16, 2011 · A method to improve the calculation of overland flow in distributed groundwater recharge models is presented and applied to two sub-catchments in the Thames Basin, UK. Recharge calculation studies tend to simulate the runoff flow component of river flow in a simplistic way, often as a fraction of rainfall over a particular period.
