If the direction of advance of a storm is the same as the direction of the resulting runoff in the drainage basin, such runoff will generally

Direct runoff is made up of
Rainfall of magnitude 4.3 cm, followed by 3.7 cm, occurred on two consecutive 4 h durations on a catchment area of 25 km2 and there resulted a DRH (after isolation of base flow in the flood flow hydrograph) with the following ordinates starting from the beginning of the rainfall.

A canal is 80 km long and has an average surface width of 15 m. If the evaporation measured in a class A pan is 0.5 cm/day, the volume of water evaporated in a month of 30 days is (in m3)
Horton's infiltration equation was fitted to data from an infiltration test. It was found that the initial infiltration capacity was 20 mm/h, the final infiltration capacity was 5 mm/h and the exponential decay constant was 0.5 h-1. If the infiltration was at capacity rates, the total infiltration depth for a uniform atom of 10 h duration would be
For Western Ghats, the relation between runoff ‘R’ and rainfall ‘P’ (both in cm), given by Inglis and De Souza formula is:
A direct runoff hydrograph due to a storm idealized into a triangular shape has a peak flow rate of 60 m3 / s occurring at 25 hours from its start. If the base width of this hydrograph is 72 hours, and the catchment area is 777.6 km2, the runoff from the storm is
Maximum surface run-off is because of
Rain fall intensities in mm/hr at half an hour interval during a 4-hour storm were: 5, 9, 20, 13, 6, 8, 16 and 3 mm/hr. If the corresponding observed runoff is 27.45 million m3 from a basin having an area of 1830 Km2? The ϕ-index for storm is
