在积水入渗条件下，累积入渗量是土壤性质、初始条件和土壤表面水层厚度的函数。对于任意土性和任意水层厚度随时间变化但初始含水率均匀的情况，通过对常微分方程组的积分来预测累积入渗量。如果水层厚度随时间不变，则可得到完整的分析结果。在实验室中进行的仔细的实验观察证明了结果的有效性和准确性。
Under ponded infiltration the cumulative infiltration is a function of soil properties, initial conditions, and water layer thickness above the soil surface. For arbitrary soil properties and arbitrary dependence of water layer thickness on time but uniform initial water content, an optimization technique predicts the cumulative infiltration from the integration of an ordinary differential equation. If the thickness of the water layer is constant with time, a fully analytical result is obtained. Careful experimental observations carried out in the laboratory illustrate the validity and accuracy of the result.
