Military Hydrology. Report 17. A Quasi-Conceptional Linear Model for Synthesis of Direct Runoff with Potential Application to Ungaged Basins

Abstract

A quasi-conceptual linear model is developed for synthesis of the instantaneous unit hydrograph (IUH) by employing drainage network properties. This IUH is then employed in convolution for synthesis of the direct runoff resulting from a rainfall event. Because the approach contains parameters that can be determined from basin morphology, it is potentially applicable to ungaged basins. A computer model, designated as GMHS, is developed using this approach for hydrograph synthesis. This model is verified on five small agricultural basins. The model results compare well with observations in light of accuracy of the parameters and data. Keywords: Geomorphology; Hydrology; Military hydrology; Streamflow; Computer programs; Streamflow forecasting.
