online_routing_clark:   Comparison of Clark's original unit hydrograph with Ponce's Clark unit hydrograph   Formulas Q = Ij * Ak             Convolution (See text example). O2 = C0I2 + C1I1 + C2O1        C0 = (Δt/K)/[2+(Δt/K)] C1 = C0        C2 = [2-(Δt/K)]/[2+(Δt/K)] References Comparison of two types of Clark unit hydrograph Ponce, V. M. 1989. Engineering Hydrology, Principles and Practices. Prentice Hall, pages 311-313. Example INPUT DATA: Enter unit hydrograph duration tr (hr):      Enter time interval Δt (hr):      Enter storage constant K (hr):      Enter number of increments of [watershed] drainage area:      Enter increments of [watershed] drainage area Ak (km2) (separate each value with a comma; maximum string length is 200 characters). Ak:      ECHO OF INPUT: Unit hydrograph duration tr =   hr               Time interval Δt =   hr                Storage constant K =   hr                 Number of increments of [watershed] drainage area =   Ak  (0) =  .    OUTPUT: Time Interval Time (hr) C0I2 (Ponce's Clark) (km2-cm/hr) C1I1 (Ponce's Clark) (km2-cm/hr) C2O1 (Ponce's Clark) (km2-cm/hr) Outflow (Ponce's Clark) (km2-cm/hr) C0I2 (Clark's original) (km2-cm/hr) C1I1 (Clark's original) (km2-cm/hr) C2O1 (Clark's original) (km2-cm/hr) Outflow (Clark's original) (km2-cm/hr) Outflow (Ponce's Clark) (m3/s) Outflow (Clark's original) (m3/s) 0 0 0 0 0 0 0 0 0 0 0 0   Your request was processed at  10:29:25 pm on December 22nd, 2024   [ 241222  22:29:25 ].
