Semi-distributed rainfall-runoff modeling utilizing ASTER DEM in Pinang catchment of Malaysia

This paper presents the application of TOPMODEL in the Pinang catchment of Malaysia for stream flow simulation. An attempt has been made to use remote-sensing data (ASTER DEM of 30 m resolution) as a primary input for TOPMODEL in order to simulate the stream flow pattern of this tropical catchment....
