Abstract

There are many parameters of the watershed that govern the hydrologic responses in the process of rainfall-runoff process. One of the parameters is geomorphological parameters. Some parameters have been well known for their contribution to streamflow discharge, the other parameters do not. We explore some geomorphological parameters that strongly influence the hydrologic response of a watershed but received inadequate attention to be investigated and discussed. We refer to a rainfall-runoff model in which rainfall is the primary input parameter and runoff in the stream is the output. By identifying a number of rainfall-runoff and other hydrologic models, the data parameters required to run the mode and obtain the output i.e. flood could be identified. We concluded that the watershed parameters of the hypsometric curve, watershed shape, drainage density, channel length, channel slope, channel cross-section, Horton’s stream, and degree of meandering, are important watershed parameters but lack attention from scholars.
