摘要
万泉河流域面积大、降雨分布不均匀,洪水受多种复杂因素的影响,因此采用多单元的水文学模型与河道水力学模型相结合的预报系统。提高模拟精度的重点是水力学模型中内、外边界条件的处理及水流阻力项的计算。采用20世纪90年代10余场洪水资料对模型进行了率定和检验。
In order to study flood management problems of the Wanquan River basin, a hydrological multicell and hydraulics model has been built up to simulate complex flood routing behaviors. To increase modeling accuracy, some treatments of interior and exterior boundary conditions, and calculations of variable resistance terms are discussed. Finally, the model is calibrated and verified against tens flood events observed during 1990～2000.
