CIV E 632 - COMPUTATIONAL HYDRAULICS AND HYDROLOGY SPRING 2009 HOMEWORK No. 6 Prove that Eqs. 10-10 and 10-11 of the text (Ponce: Engineering Hydrology) are one and the same. A watershed has a drainage area of 1000 km2. The following rainfall hyetograph has a produced a peak of 491 m3/s at a time of 66 hr (11th time interval). Hyetograph time interval = 6 hr Effective rainfall duration = 24 hr. Increments of effective rainfall intensity (cm/hr): 0.2, 1.0, 0.8, 0.4 What are the parameters (K and n) of the method of cascade of linear reservoirs applicable to this watershed?
