Predictions in Ungauged Small Watersheds Based on Improved GIUH
摘要
Abstract
In order to get higher precision of forecast results,combined with surface unevenness of areal precipitation,the initial probability was made an appropriate adjustments. At the same time,considering a certain degree of lag time compared overland flow concentration and subsurface flow concentration with channel flow concentration,the slope as a special river was introduced to geomorphological instantaneous unit,maintaining the computational structural consistency of geomorphological instantaneous unit. The application results show that the aver-age error of improved geomorphologic instantaneous unit hydrograph is 6. 02%,which is better than un-improved geomorphologic instanta-neous unit hydrograph with average error of 14. 70%.关键词
