The key of the utilization of flood resource is to know flood occurrence course and movement rule, and floodrouting state can be reappeared.
洪水资源利用的关键在于了解洪水的发生过程及其运动规律，再现洪水的演进状态。

The GIUH based on the width function considering the spatial changes of hydrodynamic parameters is built, by which the results of floodrouting of watershed are satisfactory.
A floodrouting model for river-type reservoirs was developed to calculate the dynamic reservoir capacity during the real-time flood regulation based on the hydrodynamic method.
