随着我国经济的发展，蓄滞洪区内不断进行开发利用，洪灾造成的生命与财产损失越来越严重，对滞洪区的调度运用就显得至关重要。建立蓄滞洪区一二维多口门衔接的洪水演进数学模型，根据1956年洪水资料，应用此模型对永定河泛区洪水演进过程进行模拟计算，通过计算对泛区的代表位置的水位和进行了验证。验证结果表明计算值与调查值吻合较好，同时模型对不同来流情况进行数值模拟，通过模拟得到泛区内分洪口门水位启用时间、淹没情况等信息。从而为泛区的防洪调度提供理论依据。
隨著我國經濟的髮展，蓄滯洪區內不斷進行開髮利用，洪災造成的生命與財產損失越來越嚴重，對滯洪區的調度運用就顯得至關重要。建立蓄滯洪區一二維多口門銜接的洪水縯進數學模型，根據1956年洪水資料，應用此模型對永定河汎區洪水縯進過程進行模擬計算，通過計算對汎區的代錶位置的水位和進行瞭驗證。驗證結果錶明計算值與調查值吻閤較好，同時模型對不同來流情況進行數值模擬，通過模擬得到汎區內分洪口門水位啟用時間、淹沒情況等信息。從而為汎區的防洪調度提供理論依據。

With the economic development and the utilization of flood detention areas ,the loss of life and property becomes increas‐ingly serious .The operation of flood detention areas is vitally important ..This paper establishes a flood routing numerical model linked up by 1-D and 2-D at muti-entrance .Based on 1956 flood data ,it simulates the flood routing of Yongding River flood plains through the calculation ,the water level of representative sites and the starting time of flood gates are tested .The test results show that the calculated values are in good agreement with the investigated ones .At the same time ,different flood stages are simulated , and the starting time of flood gates and other submerged information are obtained to provide a theoretical basis for the flood control scheduling of the flood plains .
