static

Computes the Manning bottom friction.

This function calculates the frictional using the empirical Manning formula. The result depends on the local water height and momentum components.

The friction coefficient is defined by the Manning parameter, which may need to be adjusted depending on the bathymetry, resolution, or physical characteristics of the domain.

Parameters

h	Water height
hu	x-direction
hv	y-direction

Returns

Bottom friction force contribution to the momentum equations
