Question: Use the Rational Method to determine the peak discharge generated by an 18-hr rainfall event with a recurrence-interval of 100 years for a watershed located

Use the Rational Method to determine the peak discharge generated by an 18-hr rainfall event with a recurrence-interval of 100 years for a watershed located in Western Kentucky. The watershed is dominated by sandy-loam soils with high infiltration rates, and has corn and soybean row crops. The time of concentration was estimated to be 90 minutes. Report peak discharge in metric and English units. Explain any assumptions that need to be done in order to solve the problem.
