Hi
I am exploring options in HecRAS 2D run only. I have created a mesh and give upstream BC as flow hydro-graph and downstream BC as normal depth.
My major concern about adding flow change locations. Could we add separate BC to insert flow hydro-graph in the route of major stream next to upstream BC that we generally do in HecRAS steady flow. For the same do we need to give accumulated flow or difference of flow from upstream BC flow value. Could anyone please help me in this regard.
