fr_equiv_depavg_shstr_coef()

double fr_equiv_depavg_shstr_coef	(	double	depth,
		double	roughness_height
	)

This routine calculates a coefficient , such that the shear stress is found as follows: where is the shear stress as calcuated using near bed velocity. Hence, this routine yields a coefficient that will convert the shear stress found using near bed velocity into an approximate shear stress that would result from using depth averaged valocity.

Parameters

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

Returns

c_eda (double)

Note

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