The soils, land use, and hydrologic conditions for a 500-hectares watershed are as follows: Soil Subarea Land Use Treatment and Hydrologic Hectares Condition Group 100 C Residential 25% imp 200 A Commercial and business 100 D Cultivated Straight Row, good condition 100 B Forest, dense The hydraulic length of the watershed is 1500 m and the mean slope is 0.05%. During the growing season, 25 mm and 15 mm of rain fell on the 1st and 2nd day of the month, respectively. A critical duration of storm causing flood of 3 hours with return period of 10 years resulted to 75 mm of precipitation fell on the 6th day. The AMC on the last day of the previous month was 50 mm and the value of CA is O.80. Compute the AMC of the 7th day of the month. determine the run off volume (in cu.m) for the flood on the 6th day using CN method. Use la =0.2S, Determine the peak run off rate using CN method
