闸坝控制感潮河道洪水位预报方法探讨

Discussion on the prediction method of flood level of tide rivers controlled by sluice and dam

针对闸坝控制感潮河道洪水位预报,应用雨洪定律的计算方法,从雨洪期间各时段降水量开始,按时序演算转化为入河虚拟断面流量,并建立水位-虚拟流量关系,由涨水之初水位及虚拟流量反推洪水位及涨水过程。研究方法简单便捷,预报快速高效,在闸坝控制感潮河道洪水位预报中具有一定的应用意义。

For the prediction of flood level in tidal rivers controlled by gates and dams,the calculation method of rain and flood laws is applied.Starting from the rainfall during each period of the rain and flood period,the time series calculation is converted into a virtual cross-sectional flow into the river,and a water level virtual flow relationship is established.The flood level and flood process are inferred from the initial water level and virtual flow during the flood.The research method is simple and convenient,with fast and efficient forecasting,and has certain application significance in the prediction of flood levels in tidal rivers controlled by gates and dams.
