本文提出了一种高非均质介质中非饱和渗流的放大模型。高导电域中的流动用Richards方程描述，而与导电性差的块体之间的水交换则用具有扩散记忆核的非局部汇项来描述。通过数值算例对模型进行了检验。
This paper presents an upscaled model for unsaturated flow in highly heterogeneous media. Flow in the highly conductive domain is described with Richards' equation, while water exchange with poorly conductive blocks is captured by a non‐local sink term with a diffusive memory kernel. The model is tested with a numerical test case.
