Compute rate of runoff using the rational formula for a 256-acre rural drainage area consisting of three different watershed areas as follows:

Steep grass area = 15% Forested area = 30% Cultivated fields = 55% If the time of concentration for this area is 2.4 hours, determine the runoff rate for a storm of 50-year frequency. Use the rainfall intensity curves in Figure 16.2. Use Table 16.2 for runoff coefficients. What will be an ideal response?
