Consider a rainstorm of duration tr = 7.5 h and constant rainfall intensity P = 50 mm/h. Assume an initial soil relative saturation of 50% and three soil types: silt loam, sand, and clay. 1. Determine if ponding is possible. 2. If ponding is possible, we will use the Philip model to calculate infiltration. Determine sorptivity, ponding time and compression time. 3. Plot the infiltration rates for the three soil types. 4. Determine the cumulative infiltration. Will there be runoff
