The rainfall on five successive days were measured as 100 mm, 80 mm, 60 mm, 40 mm and 20 mm respectively. If the infiltration index or the storm loss rate for the catchment area is earlier estimated as 50 mm/day, the total surface run off will be                        

The normal annual precipitation at stations X, A, B and C are 700 mm, 1000 mm, 900 mm and 800 mm respectively. If the storm precipitation at three station A, B and C were 100 mm, 90 mm and 80 mm respectively, then the storm precipitation for station X will be                        

The best unit duration of storm for a unit hydrograph is                        

The unit hydrograph due to a storm may be obtained by dividing the ordinates of the direct runoff hydrograph by                        

The unit hydrograph of a specified duration can be used to evaluate the hydrograph of storms of                        

S-hydrograph is used to obtain unit hydrograph of
