2.2 Understanding the 2D Mesh (Zone) in InfoSWMM 2D

The 2D zone, alternatively described as a mesh, consists of a series of contiguous triangles, whose shared boundaries cover the catchment surface. The height of each point on each triangle is derived from a ground model GRID or TIN.

It is … Read the rest
