摘要
在大庆市洪水模拟中引入坐标变换、交替方向、交错网格、线性递推、隐格式的二维非恒定流模型,可完全适应不规则的河流边界,实现水流的快速预报;同时,将GIS、RS和洪水模拟模型有机地结合起来,实现实时动态地率定模型参数、显示洪水演进过程与查询信息。
The twodimensional unsteady flow model is developed by coordinate transformation,alternating direction,staggered grid,linear recurrence,implicit scheme on the flood simulation in Daqing. The model can totally fit the irregular river boundary and predict quickly water flow. At the same time, the flood simulation model are combined with GIS,RS to dynamically test the parameters,show the flood routing process and inquire the flood message.
