The stage storage relationship at a pond site is described by S = 450 h^1.2 where S = storage in the pond in m^3 and h = water level in meters above the spillway crest. The discharge over the spillway is described by O = k_wL(2g)^0.5 h^1.5 where the discharge (O) is in m^3/sec, k_w = 0.40 (discharge coclTicicnt), L = 1.0 m (spillway crest length), and g = 9.81 m/sec^2 (gravitational acceleration). Initially, h = 0 and S = 0. Build a [2S/Delta t) + O] versus (O) relationship for pond stages in 0.2 m increments up to 0.6 m over the spillway crest. Perform storage routing computations for the inflow hydrograph provided below to determine the peak outflow and stage. A spreadsheet program may prove helpful.
