fr_bedshstr_drag_coef()

double fr_bedshstr_drag_coef	(	double	depth,
		double	roughness_height
	)

This routine calculates a coefficient c_f, such that the shear stress tau is found as follows: This coefficient is for depth integrated model velocity.

Parameters

[in]	depth	(double) - water depth
[in]	roughness_height	(double) - roughness height

Returns

double friction coefficient

Note

The minimum ratio of depth to roughness_height is 1./29.7
