Thus, Farmer John has built a set of drainage ditches so that Bessie's clover patch is never covered in water. Instead, the water is drained to a nearby stream.
Method combining DEM with stream network leads to a more accurate drainage network from surface runoff modeling, especially for flat area. Method of modifying existing DEM by add…

A precipitation interpolation experiment is taken to test the model in Guxian drainage area. Guxian drainage area lies in down stream of Yellow river basin belong to a mountain area.
