Development of a flood forecasting system and its application to upper reaches of Zhangweihe River Basin
With changes of underlying surface in Zhangwei River Basin in recent years,it is necessary to build distributed flood forecasting model in upper stream of Zhangwei River Basin to study the hydrologic processes,which can also provide technical support for the flood control department.Based on the physically characterized distributed hydrological model – EasyDHM – a more generalized and expandable method,a flood forecasting system (FFS) has been developed that is equipped with updated modules for pre-processing and automatic parameter optimizing.The general functions of FFS consists of three major parts:(1) a preprocessing module for hydrological analysis and modeling inputs,(2) a model calculation module,and (3) a results analysis module.With its application in the upper reaches of Zhangwei River Basin,this system exhibited a satisfactory performance so that it can provide more information for flood control and dispatch.
