Abstract:
The primary purpose of flood frequency analysis is to determine a timeframe of potential flood events. Analyzing flood frequency is a process that involves collecting years of quantitative data on discharge rates, calculating the probability of exceeding a certain rate of discharge, and calculating the average interval between events equaling or exceeding a certain rate of discharge. The Big Creek Watershed drainage area covers an area of 549 square miles in Western Kansas, including Ellis, Trego, Gove, and Sheridan Counties. This research analyzes 79 years of data collected manually and with automated sensors by the USGS at the intersection of Big Creek and US-183. This research aims to provide a statistical probability estimate for a period of time that major flooding events may occur within.
