WebbThe coefficients for the 2-, 5-, 10-, 25-, 50-, and 100-year rainfall events are given in the table below for each county in South Carolina. The intensity values for time of concentration of 5, 10, 15, 30, and 60minutes are also listed in the table for the same frequencies. Webb5.3.2 Precipitation Analysis Rainfall Hyetograph Rain is usually measured in incremental volumes at gauging stations. These increments take the form of daily volume, or volume at some other increment of time. It is possible to plot the rainfall volume, or its equivalent the rainfall intensity, for incremental times during the event.
