WebbThe incremental rainfall intensity data given in the table below were recorded at a gage located on a small urban watershed. Using a 0.5‐hour time step: (a) Plot the rainfall Hyetograph. (b) Determine the total rainfall depth during the storm event. (c) If the runoff depth is 4.65 mm, find the phi- index in mm/ hr. Webbof rainfall intensity and the pertaining time span. Since we are dealing with 1-hour time intervals, the rainfall depth ends up being numerically equal to intensity – e.g., the … thomas haveron mdWebbThe alternating block methodology is used to develop a design hyetograph from DDF values. Here, the cumulative rainfall depth D(T) is calculated for every 5 minute interval up to 24-hours using Equation [1]. The design storm is centered on the peak 5-minute rainfall depth at 12 hours, which corresponds to the 5 minute DDF value (5.7 mm). thomas haverty medfield ma
