Directions: The ordinates of a 2-h unit hydrograph at 1 hour intervals starting from time t = 0, are 0, 3, 8, 6, 3, 2 and 0 m3/s. Use trapezoidal rule for numerical integration, if required.
A storm of 6.6 cm occurs uniformly over the catchment in 3 hours. If 0-index is equal to 2 mm/h and base flow is 5 m3/s, what is the peak flow due to the storm?
