Opis

Morphometry deals with the management and mathematical analysis of the configuration of the earths surface and of the slopes and dimensions of its landforms. It is used to determine the geometry of the watershed especially among its stream network. Morphometry gives a little idea of erodibility of soil. Watershed characteristics play a vital role on the hydrologic performance of watersheds. Hence, a number of parameters, which signify the watershed characteristics, are evaluated from the topographical maps. Various morphometric parameters are computed to evaluate the geomorphic stage of the basin, which is the indication of intensity of erosion from the basin.In the case of shortage of hydrologic data, morphometric parameters play an important role in predicting the response of the catchment. Hypsometric analysis aims at developing a relationship between horizontal cross section area of the subwatershed and its elevation in a dimensionless form. For determination of hydrologic variables, such as precipitation, evaporation etc. with respect to the altitude is useful by the hypsometric curve.
