Regression:

Joint Publications with Dr. D. Hansen:

George, G.H. & Hansen, D., “ Conversion between Quadratic and Power Law for Non-Darcy Flow ” , Journal of Hydraulic Engineering, vol. 118(5), pages 792-797, 1992.

This technical note outlined a method of obtaining best fit parameters   r   and   s   for a quadratic regression model
            i   =   r V + s V ²
(where   i   is the hydraulic gradient and   V   is the bulk speed (discharge per unit cross-sectional area) of water flow through partially obstructed media such as rock fill dams), given only the parameters   a and N   of a power law model
            i   =   a V ^N
for the same flow.
