Due to issues of dongting lake districts flood composition, the evolution of sediment flow, the river and lake ( r & l ) distribution characteristic as well as the layout of r & l - dredging engineering, the article simulated the model of the dongting lake terrain change by using the gis technology and adopted the limited volumetric method to establish the two - dimensional hydraulics computation model of lake in order to forecast the water level, the flow capacity, the speed of flow and changes of flow field after implemented the project, which have provided the reliable theoretic basis for the decision - making and implementation of renovation for river course, canal and harbor and river course - dredging engineering
摘要針對洞庭湖區的洪水組成、水流泥沙演變、河道湖泊水系分佈特點以及河道湖泊疏浚工程布局情況，利用gis技術模擬洞庭湖地形變化，採用有限體積法建立了湖泊二維水力學計算模型預測疏浚工程實施后的水位、流量、流速流場變化，為河道、航道港口整治、河道疏浚清淤等工程決策與實施提供了可靠理論依據。Using flood progress model and the different discharge of feilaixia reservoir, we can calculate in time the water level and discharge of middle - lower reaches of beijiang, thus increase the accuracy of flood forecast and provide the important technical support for the further research on the optimal dispatch method of f lood control system
其中依據水文學和水力學相結合的洪水演進模型，可根據飛來峽水庫不同的下泄流量，及時計算北江中下遊河道的水面線和下泄流量，提高了洪水預報的精度，為進一步研究防洪體系優化調度方法提供極其重要的技術支撐。
