FluidFlux Small River

heyy, I’m currently trying my hand at FluidFlux. There’s a lot on Youtube, but not what I’m looking for. I want to build a small river that flows into the FluidFluxOcean. Well. This FluidFluxDOmaine does not make it easy for me that the water simply follows this depression. It constantly runs over the edge in between or at the end. It then builds up at the end. I used UIWS before, but it doesn’t look as authentic as I would like. Does anyone have any tips?
