Problem 4.8. Determine the flood volume in ha-m (ac-ft) for a 50-year return period storm for the dormant season at your present location. The 360-ha (900-ac) watershed in row crops, terraced on Hydrologic Soil Group C in good condition for one-third of the area, and the remaining two- thirds is in woodland on Hydrologic Soil Group D in poor condition. Assume 25 mm (1 in.) of rainfall occurred 3 days prior to the design storm and the critical storm duration is 24 h.
