Build a 2S/∆t + O versus O relationship in 0.2-m increments for a pond that is expected to reach a depth of 1.0 m over the top of the service spillway (normal pond level). The elevation-storage relationship for the pond is described by S = 600 h1.2, where S = storage in the pond in m3 and h = water level in meters above the service spillway. The discharge over the spillway is described by O = kwL(2g)0.5 h1.5, where O = discharge in m3/sec, kw = 0.45 (discharge coefficient), L = 0.3 m (spillway crest length), and g = gravitational acceleration. Initially, h = 0 and S = 0, and the routing interval (∆t) is 8 minutes.
