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.
