摘要
本文对平原水文模型中如何充分而又实际地运用土壤水动力学的理论和方法进行了探讨,用数值法求解一维垂向饱和-非饱和里查兹方程来模拟垂向水流和土壤水及地下水动态;用稳定状态的近似解来计算潜水蒸发;用非线牲水库概念模型来模拟地下水对河道的排水过程.所建议的方法在五道沟实验区试用,效果良好.
An attempt has been made to apply soil moisture dynamics to the hydrologic modeling for plain areas. In the model, one dimentional Richards equation is solved numerically for the vertical fluxes of water in the unsaturated-saturated zone and in turn for the fluctuation of water table; the evaporation from the groundwater is estimated by a steady state approximation and the discharge simulated by means of a conceptual sub-model of nonlinear reservoir type. The proposed model has been tested at the Wudaogou E...
