用数值法模拟一维均质土壤水分运动的数学模型和计算方法,及其在降雨入渗和蒸发条件下的运用已分别在文献[1]、[2]论述过。本文阐述文献[1]所提出的数学模型和计算方法在不同地下水位控制和蒸发条件下的具体运用。公式序号续文献[2]。一、在定水位和蒸发条件下的运用在水平排水系统或水井控制下,地下水位可以保持在一定水位。当有河流、湖泊、水库或地下水侧向径流补给的情况时,地下
Mathematical models and calculation methods of numerical simulation of one-dimensional homogeneous soil moisture movement, and their application under rainfall infiltration and evaporation have been discussed in [1] and [2] respectively. This article describes the specific application of mathematical models and calculation methods proposed in [1] under different groundwater level control and evaporation conditions. Formula serial number continued reference [2]. First, the use of fixed water level and evaporation conditions Under the control of horizontal drainage system or wells, groundwater level can be maintained at a certain level. When there are rivers, lakes, reservoirs or groundwater lateral runoff recharge, underground
