Good day, I would like some assistance with something I am on.
I am current working on a floodline analysis project where I would like to have a development along the floodplain. It has been suggested that I add a berm along the channel to divert the water so the development can carry on. I managed to add a berm but editing my terrain but when I compute my analysis, water still goes through my berm.
As shown in the image, peach colour is the water and the berm is shown as red solid polygon
Thank you in advance
