For an infiltration capacity curve for a watershed the following is given:Initial infiltration capacity f0 =11.66 in./hr time constant k = 0.07 1/hrultimate infiltration capacity fc = 0.83 in./hr.

 Estimate the infiltration rate at times = 0, 10, 20, 30, 40, 50, 60, 70 minutes?(Answer: for example, at t = 20 mins, fp = 3.50 in/hr)

 Derive an infiltration capacity versus time curve? For the 70-minute period, estimate the total volume of water infiltrated in inches?(Answer: approximately 3.7 in).

I need step by step solving!
