Dear Experts,
The thing is, how to connect each 2D flow area if I divide a catchment into different 2D flow areas by Thiessen’s Polygon Method and establish the grids to enter gridded precipitation data respectively?
According to my course materials, it suggests that I connect each 2D flow area by hydraulic structure(SA/2D Area Conn). However, will it be unrealistic due to the possible influence of dam on hydraulic property? Furthermore, is hydraulic structure the only way to connect each 2D flow area? Or are there any better methods to precisely connect multiple 2D flow areas?
And every time I use SA/2D Area Conn to connect 2D areas it doesn’t work . I use a simple examlpe to try connect 2d areas and cut profile from terrian.
I would appreciate for your help.
