The table below lists rainfall data recorded at a USGS gage for the storm of September 1, 1999. The basin area is 2050 acres. Using these data, develop a mass diagram (in vs. t) and a rainfall hyetograph (in./hr vs. t) in 15-min intervals and determine the time period with the highest intensity rainfall.
