a storm of 3 hours duration has rainfall intensities of 30 mm/h for the first hour, 50 mm/h for the second hour, and 20 mm/h for the final hour. the initial infiltration rate, f0, and the terminal infiltration rate, fc, are 22 mm/h and 5 mm/h respectively. if the excess rain is equal to 70% of the total rain, calculate the value of the decay constant, k, in the hortons's model shown below:
