感潮河网区洪水水位预报--以温州龙湾区为例

Prediction of Flood Water Level of Tidal River Network Area:A Case Study of Longwan District in Wenzhou

温州龙湾区感潮段河网复杂,易受洪涝灾害影响。利用MIKE 11的水动力模块,根据河网情况、断面数据、边界条件等,建立感潮河网一维水动力模型。并基于所建模型,模拟优化水闸的调度方案,模拟不同降雨条件下的河道水位,并将最高水位与2007年实测水位进行比较,结果表明:模拟结果与实测数据基本一致,该模型具有一定的可靠度。

Longwan district of Wenzhou city is located in the tidal river network area,which is vulnerable to flood disasters.Based on the hydrodynamic module of MIKE 11,a one-dimensional hydrodynamic model of the tidal river network was established according to the river network,riverbed section data and boundary conditions.According to the model,the scheduling scheme of the sluices was simulated and optimized.The river water level was simulated under different rainfall conditions,and the highest water level was compared with the measured data in 2007.The results showed that the simulation results were basically consistent with the measured data,which proved that the model was reliable.
