Dear all,
I am new to the HEC-RAS model, but have some experience with SOBEK.
I am trying to set-up a HEC-HMS (hydrological) and HEC-RAS (hydraulic) models. For the rainfall-runoff model (hydrological), I am required to set-up a 2D model that is able to connect to HEC-RAS which would be 1D. I will save you the explanation why 2D is necessary for hydrology and 1D for hydraulic.
The main question is: is the rainfall-runoff available in 2D grid? I need to describe the street drainage processes and simulate fast-responding rainfall events.
Thanks in advance.
