Abstract
Land-use and land cover (LULC) changes for the Jackson, TN area from 1992–2011 were evaluated based on data from the National Landcover Database. During the time of study, this area underwent noted changes in LULC with an increase in the area defined as urban and decreases in forested and agricultural areas. This study also makes note of the increase in the number of days flash flood warnings were issued during the 1990’s as compared to the 2000’s. During the same time period, high intensity rainfall events during 1990’s (n=198) did not appreciably increase when compared to the 2000’s (n=208); therefore, increases in flash flood warnings were not influenced by changes in rainfall events. The purpose of this work was to determine if changes in LULC and increases in flash flood warnings were statistically significance. Overall, an increase in runoff of 25% for the study area between 1990-2011 was determined. The majority of correlation analyses between runoff/urban and runoff/agriculture were also found to be significant.
