Revised Flood Hazard Data on West Chickamauga Creek in the Vicinity of East Ridge, Tennessee

摘要

This report provides flood hazard information for the portion of West Chickamauga Creek (stream mile 0.00 to mile 3.15) which lies within the corporate limits of East Ridge, Tennessee. TVA previously prepared the information contained in the 1980 flood insurance study published by the Federal Emergency Management Agency (FEMA). In mid-1977 the US Geological Survey (USGS) published a major revision of flood discharge records for the former gage on West Chickamauga Creek near Kensington, Georgia. This gage is the primary source of hydrologic data used to establish floodflow frequencies for this section of West Chickamauga Creek. An analysis of the gage data revision revealed a substantial change in the previously published information. FEMA has revised or intends to revise the flood insurance study maps and profiles to reflect these changes. (ERA citation 09:019092)
