Research on Flood Control Planning in River Valley Basin Based on MIKE Hydrodynamic Model
To study the strategies for urban flash floods control in river valleys and basins,using measured terrain and river section data,and based on the project of Yunhe Water Network Construction Planning,thispaper used the MIKE11-21 Coupling software to establish a mathematical model for flood inundation in Fuyun River,Huangxi River,and region in their both sides in Yunhe County.Different planning and design schemes were proposed to simulate and analyze the impact of design floods on the region under various planning conditions.From the dynamic perspective of flood inundation and drainage process,it analyzed the problems of regional flood control.Through counting up the flood recurrence period,inundation area,and inundation duration,it quantitatively analyzed the impact of flood disasters.Research has shown that flood simulation models based on MIKE can reflect the characteristics of flood evolution in river valleys and basins well,and the analysis results are more accurate and reasonable with high application values.
