3. a) For the following 15 min precipitation data from a 2-hr storm, fill out blanks in the table below using SCS curve number method CN=80, 1=0.28-0.5 inches (using the equation and Figure on p197, the cumulative excess/runoff Qoccurs when precipitation excess the initial abstraction at t-45 minutes). Keep three decimal points for results (26"). b) determine the total net rainfall and total loss (inches) (4) Incremental rainfall excess (inches) Incremental precipitation (inches) Incremental rainfall loss (inches) Cumulative Precipitation (inches) 0.0 0.1 0.3 0.6 0.9 1.1 1.2 cumulative excess/runoff using SCS method 0.0 0.0 0.0 0,25) 0.492 Time (minutes) 0 15 30 45 60 75 90 105 120 0.1 0.2 0.1 0.2 is 4428 01737 0.967 1 . 2012 . 1.3 1.4 947 . 9388 1714 c) if there is no initial abstraction, determine the O-index (in/hr) for the above storm (20) (P., 2:5² P+,..
