The initial infiltration capacity (fo) of a catchment is estimated as 5.5 mm/hr, the time constant as 0.45/hour, and the capacity (fc) as 0.5 mm/hr. Use Horton’s equation to find;
a) The value (ft) at t = 15 mins, 30 mins, 45 mins, 1 hr, and 3 hrs.
b) The total volume of infiltration over the 3 hrs period. Assume continuously ponded conditions.
