Plot the resulting DRH due to 3 rainfall events, assuming a phi-index of 0.20 cm/hr. • Recall that the phi-index represents the rate of infiltration. • The hydrograph plots RUNOFF rates, where runoff = precipitation - losses. Note that the rainfall magnitude is reported as total rainfall depth in 6 hrs, so convert infiltration as a total for every 6 hr period. b. Assuming a baseflow of 30 m3/s, what are the ordinates of the storm hydrograph?

Determine the magnitude of the friction force acting on the 100kg block shown if P=100N. The coefficient of friction is 0.20. The forces applied to the block is initially at rest.
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.
