Adding (turbulent) diffusion to the shallow water model (part of freeflow):
For now using constant eddy-viscosity. Turbulence models will be added in separate issues. The implementation also contains 2 wall shear stress implementations:
- no-slip implementation
- law-of-the-wall implementation
One test has been added: Poiseuille flow test: for flow in a channel with rough side walls. This test has an analytical solution.
Which issue this MR fixes: #706 (closed)
