摘要
Abstract
For calculating storm flood of special small watershed in Guangxi, each with catchment area less than 1km2, the Naci instantaneous unit hydrograph and reasoning formula were adopted respectively. The results of storm flood calculation for the small II-scale reservoirs located in various special small watershed of Guangxi demonstrate that the watershed parameter of θ value is much less than the minimum value specified by the Guangxi Hydrology Chart when applying reasoning formula, but the calculation results of flood peak and reservoir flood regulating are close to that out of Naci instantaneous unit hydrograph method which is not subject to limit of θ value. Therefore, calculating storm flood for special small watershed in Guangxi with reasoning formula is able to break the limit of θvalue, the watershed parameter specified by the Guangxi Hydrology Chart.关键词
