Influence of pit removal algorithms on surface runoff simulation

[摘要] The digital terrain model (DTM) with removed pits is a precondition for hydrologic analysis. Two pit removal methods, the carving method and the filling method, are investigated in the paper for three different geomorphometric areas. The input data are di
