Hello,
Is there a way I can add lateral inflows to a 2D model? (Similarly to assigning a lateral inflow hydrograph BC to a specific XS in a 1D model.)
I already have an upstream flow hydrograph BC, but I want to add to these flows at a downstream gauge location to account for lateral inflows.
But, when I add a flow hydrograph BC internally, the flow goes forwards and backwards from this BC line, causing the channel to flood excessively upstream of it.
Thank you,
DH
