摘要
The instantaneous unit hydrograph (IUH) derived from the geomorphologic characteristics of a basin and a timing component, the velocity of the discharge, was presented by Rodríguez‐Iturbe and Valdés (1979). To analyze this geomorphologic IUH in real world basins, a study was carried out on several basins in Venezuela and Puerto Rico. The gemorphologic IUH for each basin was compared with the IUH's derived from the discharge hydrograph produced by a physically based rainfall‐runoff model of the same basins. The effects that the nonlinearities of the rainfall‐runoff model have on the derivation of the IUH are analyzed, and further, controlled experiments are carried out in which the IUH is derived under constant velocity conditions. The geomorphologic IUH's and the ones obtained in the experiments are remarkably similar in all the basins analyzed. Copyright 1979 by the American Geophysical Union.
