A watershed in the neighborhood of Holly Springs has a total drainage area of 500 acres with an average slope of 0-3%. The soil is clayey loam (Soil group - C) with different land use types comprising 30% open spaces (CN = 74), 20% commercial business areas (CN = 94), 20% residential areas (CN = 83) and the rest of the land being wooded (CN = 74). Residential area is typically a single family home with a lot size of 0.25 acres. Assume 'g' = 232 and 'h' = 23 for the IDF curve. Based on this information, estimate the average discharge that would occur from the watershed over 8 hours. Also estimate the runoff depth, infiltration and average discharge at an increment of 2 hours over 8 hours.
