Kinematic wave equation for sheet flow
WebKinematic Wave Equation Calculations T ti = sheet flow travel time (minutes) n = sheet flow roughness coefficient L = flow length (m) I = rainfall intensity (mm/hr) S = surface slope (m/m) K u = empirical coefficient equal to 6.92 in SI units or 0.933 in US units WebThe current practice of limiting the flow length in the kinematic-wave time-of-concentration equation is problematic. This paper presents and analyzes limiting criteria, including L , …
