Assuming that C = 0.25, compute the downstream hydrograph using the Convex method for the following upstream hydrograph: (0, 12, 27, 56, 53, 47, 38, 23, 15, 8, 4, 0) ft^3/s. Assume that the initial discharge at the downstream section is ft^3/s. Solution Using the formula of convex method Oi+1 = C * Ii + (1- C) Oi C = 0.25inflowDownstream001202735695320.754728.81253833.359382334.519531531.63965827.4 7974422.6098017.95735.
