10 Norfolk, VA Problem I: A gutter is designed to drain the 25-year 30-min storm runoff from a small drainage area in Norfolk, VA. Figure 1 shows the IDF curves. For a computational time step of 5 min, (1) Develop the design storm by assuming a balanced triangular distribution Rainfall Intensity (in/hr) 100 Year 25 10 (2) Can the design storm be developed using the 24-hr NRCS rainfall distribution method? Explain your answer 10 20 Duration (min) Figure 1. The IDF curves for Norfolk, VA.
