parameters: fc, the equilibrium infiltration capacity is 17 mm/hr; fo, the initial infiltration is 123 mm/hr; k, the rate constant is 0.4 hr-1; Two rainstorms pass over identical basins of area 80 km2 with the above characteristics. The first storm has a continuous rainfall of 50 mm/hr for 6 hours. The second storm has a rainfall of 75mm/hr for 1 hour, followed by 25 mm/hr for 1hour, followed by 75 mm/hr for 1hour, followed by 25 mm/hr for 1 hour, followed by 75 mm/hr for 1hour, followed by 25 mm/hr for 1 hour also for a total of six hours. Calculate the volume of infiltrated water (in m3) over the first hour, over the first four hours, and over the total six hours. Do so for each of the storms. Comment and try to explain any similarity or difference in the answers for the two storms.
An infiltration capacity curve has the following parameters:
fc, the equilibrium infiltration capacity is 17 mm/hr;
fo, the initial infiltration is 123 mm/hr;
k, the rate constant is 0.4 hr-1;
Two rainstorms pass over identical basins of area 80 km2 with the above characteristics. The first storm has a continuous rainfall of 50 mm/hr for 6 hours. The second storm has a rainfall of 75mm/hr for 1 hour, followed by 25 mm/hr for 1hour, followed by 75 mm/hr for 1hour, followed by 25 mm/hr for 1 hour, followed by 75 mm/hr for 1hour, followed by 25 mm/hr for 1 hour also for a total of six hours.
