Abstract

This research was aimed to estimate streamflow using Dawdy-O'Donnell  model based the climate data. The result of estimation showed that peak pattern streamflow was matching with observation data, but differ of  discharge amount. Nash-Sutchcliffe coefficient(E) obtained inthis modelwas worth49%. Theresults  of correlationbetweensimulation withobservationswas 0,72. The coefficient values (E) indicate that the estimation was not accurate. This causedthe parametersmodel usedhave not beenable togenerate models ofdaily fluctuations. Therefore, itis necessary tocalibratebased the characteristics on the watershed.
