| 摘 要： | 介绍了应用水箱模型建立三峡入库洪水实时连续预报模型的方法。按照河段流量传播时间将入库站(寸滩)以上干、支流划分为若干子河段,各子河段按照计算时段长分成若干单元河段,各单元河段区间降雨径流预报采用水箱模型,河道流量演算采用连续马斯京根法。对河系洪水预报模型的检验表明,预报精度在85%以上,能够满足实时洪水预报的要求。

| Abstract: | An introduction was given to the method for developing the real-time continuous prediction model for the flood inflow of the Three-Gorges Reservoir with the tank model.The main stream and tributaries above the inflow reservoir station Cuntan were divided into several sub-reaches according to the propagation time of flow,and the sub-reaches were divided into unit reaches according to the calculation time interval.The tank model was used for predicting rainfall runoff for each unit reach,and the continuous Muskingum method was adopted for flow routing.The precision of the prediction model is verified to be higher than 85%,which can meet the requirement of real-time flood prediction. |
