WebEquation (14.14) can be re-arranged in the form: ( 2 / 3) H S 3 = q 2 / g. Hence, flow per unit width q = ( 2 / 3) ( 2 g / 3) H 1.5 and for a rectangular channel of width, b: (14.17) Q = ( 2 / 3) ( 2 g / 3) b H 1.5 This is now in the form of a weir equation, which can be generalized as: (14.18) Q = C d b H 1.5 where Cd is a discharge coefficient. http://www.civil-engineering-calculators.com/Soil-Test/Permeability-By-Falling-Head-Test-Calculator
