A catchment area consist entirely of loamy sand, which typically has a saturated hydraulic conductivity of 30 mm/h, average suction head of 61 mm, and porosity of .44. Prior to a rain event the soil has an initial moisture content of θi = 0.076. The catchment area is estimated to have a depression storage of 5 mm. You are in the process of designing a stormwater management system to handle the runoff from this area, and have selected the following 1-h storm as the basis of your design:

a) The time of ponding (tp, minutes)

b) The infiltration depth (F) generated by the design storm,

c) The infiltration rate (f) of the soil at the end of the storm,

d) The volume of runoff (Q, m³) generated by the design storm.
