A catchment soil is found to have the following Horton infiltration parameters: fo = 100 mm/h, fc = 20 mm/h, k = 0.030 min 1, %3D %3D %3D and the depression storage on the ground surface is estimated as 2 mm. The design storm is given by the following hyetograph: Interval (min) Rainfall (mm/hr) 10 0-10 10-20 | 20-30 | 30-40 40-50 50-60 10 20 80 100 80 Estimate the time (min) at which ponding begins, O 27 O 35 O 20 О 38 O None of the choices
