For a catchment area of 12 hectares, the S-curve (or s-hydrograph) due to rainfall intensity of 1 cm/hour is given -t (t by Q = 3 - - 1) Where, t is in hour and Q in m³/second). The ordinate of a 3-hour unit hydrograph at t equals to 5 hours for the given catchment is (in m³/s up to two decimal places)
