The water profile seems to be correct considering flow direction and terrain profile, I would understand you are modeling a reservoir. The velocity is near to zero in the whole profile except at the oulet

I am having a similar issue.

I’m running a 2d model, diffusion wave, 2m x 2m cell, and 1m x 1 m cell on brakelines around my channel.

The model behaves ok until peak flow comes, it seems flow spreads first towards banks and then goes downstream.

I established normal depth for boundary condition upstream with a 0.005 m/m slope. I have tested several time steps and cell dimension configuration.

I don´t know if th result is correct because I´m modeling a low slope to flat area with a big peak flow.

I´d really appreciate if someone tells me what I´m doing wrong.
