5- The initial rate of infiltration for a watershed is estimated as 2.1 in/hr, the final capacity is 0.2in/hr, and the time constant, k, is 0.4 hr1. Use Horton's Equation

to find: (A) The infiltration capacity at t = 2 hr and t = 6 hr. (4 pts) (B) The total volume of infiltration over the 6-hr period. (4 pts)
