Unformatted text preview: 2. Using the methods discussed in lecture packet 4 develop a 25-year, 24-hour storm for Flagler Beach, FL. Use a time increment of hour ( t = 0.5 hours) and a total rainfall (in inches) estimated from the figures of maximum rainfall provided in lecture packet 3 (hint: you will want to use the appropriate figure for 24-hour maximum rainfall published by St. Johns River Water Management District (SJRWMD)). Base your development on the NRCS Type II, FL Modified synthetic storm ratios. (Published by St. Johns River Water Management District and provided in Lecture Packet 4 of the course notes). a. Plot the design storm cumulative hyetograph (as rainfall depth versus time) b. Plot the design storm incremental hyetograph (as rainfall intensity versus time) What is the most intense period of rainfall during the design storm? Is the design storm front-loaded, back-loaded, or neutral?...
