摘要

摘要我们提出了一种新的多维地表-地下流动耦合方法。该方法不需要网格到运河的细化或对齐，并且基于一维水力物体床和三维四面体网格的表面相交的数值特征。该方法使用公认的倾斜v型集水区和地下和波登集水区基准进行了验证。

Mesh-independent multidimensional coupling of surface and subsurface water flow models

Abstract We present a new approach for multidimensional surface–subsurface flow coupling. The method does not require mesh-to-canal refinement or alignment and is based on numerical characteristics of the intersection of one-dimensional hydraulic object beds and the surface faces of the 3D tetrahedral mesh. The method is validated using widely recognized tilted v-catchment with subsurface and Borden catchment benchmarks.
