The following rainfall data in 5-minute intervals were recorded for a storm: Time (min): Depth (in) 5 :0.07 10 :0.20 15: 0.25 20: 0.22 25 :0.21 30: 0.16 35 :0.12 40 :0.03 a) plot the rainfall hyetograph as intensity (in/hr) versus time (min) b) calculate the maximum depth (in.) and intensity (in/hr) recorded in 5, 10, 20 and 30 minutes
A 20-minute rainfall event occurred at a small catchment (without any base flow), which has 2 branch rivers (or tributaries) with individual sub-catchments. This storm generated a triangular runoff hydrograph with peak flow of 139 L/s at the catchment outlet. Base of the triangular hydrograph was 1 hr 12 minutes. The rainfall distribution and other relevant data is given in Table 1. Assume that the rainfall was uniform over the subcatchments. Calculate the followings: i) Total rainfall volume fallen on the catchment. ii) Total runoff volume generated from the catchment during this rainfall event. iii) Average runoff coefficient for the whole catchment for that particular rainfall event.

Determine average rainfall using Arithmetic mean method
During a storm, the rates of rainfall observed at a frequency of 15 min for one hour are 12.5, 17.5, 22.5 abd 7.5 cm/h. If the phi-index is 7.5 cm/h, then the total run-off will be 1. 22.50 2. 15.00 3. 30.00 4. 7.50
