A current version of the model of a unit hydrograph and its use in Taiwan and Russia

K.T. Li, N.K. Cheng, B.I. Gartsman, and A.N. Bugayets

We examine the concept, the structure and the main algorithms of the model for a geomorphological instantaneous unit hydrograph based on the kinematic wave equation. The model has been developed and is successfully implemented in calculations and forecasts of rain-induced floods on Taiwan. We present the results from its comparative testing on small catchments of Taiwan and Russia (Primorski Krai) made to verify the validity of the model in the region with substantially differing conditions. The limitations of the model and the prospects of its perfection are discussed.
