USING KIRPICH METHOD IN DETERMINING TIME OF CONCENTRATION: L 1.15 tc 51H0.385 Where: . L S H Time of concentration (minutes) Length of watercourse (m) Average basin slope (S=HL) Difference in elevation (m) i = 5.41270.1614 (10)(1+0.56)0.936 where: i = rainfall intensity(mm/h) T = Return period (years) D = rainfall duration, tc (hours) Storm water quantity can be estimated by this method. Q=C.I.A / 360 Where, Q = quantity of storm water, m3/sec C= coefficient of runoff I = intensity...
