WebDetermination of an actual runoff hydrograph from a storm event (term convolution) is accomplished when measured 5-min blocks of rainfall (termed a rainfall hyetograph) are multiplied by the ordinates of this unit hydrograph, shifted in time by 5-min steps and added together. use of unit hydrographs involves the determination of excess rainfall ... WebAlso, plot the gross rainfall mass curve and the hyetograph, Sketch the SCS triangular and curvilinear UHs for a 100-mi2 watershed which is 60% good condition meadow and 40% good cover forest land. The watershed consists of 70% soil group C and 30% soil group A. The average slope is 100 ft/mi, the rainfall duration is 3 hr, and the length to ...
