瞬时单位线在清水河宝钛工业园区洪水预报中的应用

Application of the Instantaneous Unit Line in Flood Forecast of Baotai Industrial Park Area in Qingshuihe River

针对清水河流域短缺资料的实际情况,姚家岭水位站距离下游报钛工业园区相对较近,出于安全考虑,根据地面净雨强度,将瞬时单位线转化为1小时的时段单位线推求洪水过程的方法和用单位线推求出面雨量和洪峰流量与重现期的关系查图法,能够满足预警预报的要求,可以应用于清水河流域宝钛工业园区的洪水预警预报中。

In view of the actual situation of the shortage of water resources in the Qingshui River Basin, Yaojialing water station is relatively close to the downstream Baotai industrial park. For safety, according to the ground rainfall intensity, the instantaneous unit line is converted into a 1 hour period unit line to calculate the flood process and to find out the relationship between the rainfall and the peak flow together with its reproduction period, The method can be applied to the flood forecasting of Baotai Industrial Park in Qingshui, which can be used to the flood warning and forecasting in Baotai Industrial Park area of Qingshui River Basin.
