1. A 38-year annual maximum time series from the West Fork of the Trinity River near Fort Worth is given below. Using the Bulletin 178 approach, create the flood frequency curve along with 95% confidence intervals. On the same graph, plot the data using the Weibull plotting formula (P=m/(N+1)). 2590 | 1997 14000 | 1998 | 6480 | 1999 1981 | 7960 | 2000 | 22900 26700 | 2001 | 16500 5320 | 2002 8120 | 2003 6250 | 2004 9700 | 2005 23800 | 2008 46600 | 2009 | 2120 9210 | 2010 36100 | 2011 | 6170 11900 | 2012 | 20200 9430 | 2013 | 4650 1995 | 13700 | 2014| 6400 2. Ahighway bridge is designed to just pass a discharge with an annual exceedance probability of 0.02 without overtopping the roadway a. Compute the probability that the bridge will be overtopped at least once during the next 10 years. b. Compute the probability that the bridge will be overtopped exactly once during the next ten years c. Compute the probability the bridge will be overtopped in two of the next 50 years. 3. Using the Atlas 14 website, create the IDF curve plot for Miami, Florida for the 25-, 50- and 100-year return periods
