Floods of December 1978 in Kentucky

Severe flooding throughout the State of Kentucky occurred from December 3-10 as a result of intense precipitation from two storms. The storms of December 3-5 and December 7-10 produced record peak discharges in several areas throughout central and eastern Kentucky, resulting in damages of nearly 50 million dollars and the loss of five lives. This report summarizes data collected during the floods by the U.S Geological Survey, Water Resources Division, and other federal and state agencies in Kentucky. The data include precipitation, streamflow, and water quality data (including suspended-sediment) collected during the floods. Estimates of property damages in selected basins are also provided. The information in this report is preliminary and subject to revisions.

Floodflow characteristics at White River at U.S. Highway 167, at Batesville, Arkansas, supplement 1

The Arkansas State Highway Department plans to build a new two-lane highway bridge, parallel to and approximately 50 feet (15.2 metres) downstream from the centerline of the existing U.S. Highway 167 bridge, over the White River at Batesville. The existing bridge will be altered and remain in service, thus providing a four-lane crossing after completion of the new bridge. The State Highway Department requested a hydraulic analysis of the 50-year flood at the site, considering the effect of upstream flood storage in existing (1974) reservoirs. The purpose of this study was to determine for the regulated 50-year flood: (1) the discharge and elevation of peak flow and resulting backwater with existing bridge in place; (2) the discharge and elevation of peak flow and resulting backwater if an additional bridge of the same length, parallel to and 50 feet (15.2 metres) downstream from the existing bridge, is added; and (3) the effect that a reduction of the length of the relief span would have on backwater at existing buildings on the north bank of the up-stream flood plain.

Floodflow characteristics of White River at U.S. Highway 167 at Batesville, Arkansas

The Arkansas State Highway Department plans to build a new two-lane highway bridge, parallel to and approximately 50 feet (15.2 metres) downstream from the centerline of the existing U.S. Highway 167 bridge, over the White River at Batesville. The present bridge will be altered and remain in service, thus providing a four-lane crossing after completion of the new bridge. The State Highway Department requested a hydraulic analysis of the 5O-year flood at the site, considering the effect of upstream flood storage in existing (1974) reservoirs. The purpose of this study was to determine for the regulated 50-year food: (1) the discharge and elevation of peak flow and resulting backwater with existing bridge in place; (2) the discharge and elevation of peak flow and resulting backwater if an additional bridge of the same length, parallel to and 50 feet (15.2 metres) downstream from the existing bridge, is added; and 3) the reduction in length of relief span of proposed four-lane bridge that could be made without flooding existing buildings on the north bank of the upstream flood plain. Information is provided in this report to assist the Highway Department in deciding upon the most practical and economical river crossing within existing limitations. Floodflow characteristics of the design (50-year) flood are summarized in table 1 for (1) existing bridge and embankment, (2) proposed four-lane bridge the sane length as present structures, (3) proposed four-lane bridge with length of relief span reduced to 3,000 feet (914 metres), (4) Tenth of relief span reduced to 2,000 feet (610 metres), (5) length of relief span reduced to 1,000 feet X 305 metres), and (6) without a relief span. All elevations listed in this report are referenced to highway datum, which is mean sea level.

Floodflow characteristics of Fourche Creek at Interstate Highway 430, in southwest Little Rock, Arkansas

The Arkansas State Highway Department is constructing Interstate Highway 430 (1-430) across Fourche Creek in southwest Little Rock. The Highway Department requested the U.S. Geological Survey to determine the elevation, the discharge, and the frequency of the flood of April 21, 1974, and the elevation, the discharge, and the backwater for the 50-year flood, and to report on the hydrologic effects of alterations to the proposed bridges and roadway to accommodate the larger of the two floods. All elevations in this report are given to highway datum, which is mean sea level. This report was prepared under the provisions of the cooperative agreement between the Arkansas State Highway Commission and the Geological Survey.
