Planning Flood Control Measures By Digital Computer, James Norris Cline, L. Douglas James

KWRRI Research Reports

The purpose of this study was to develop adequate guidelines whereby those interested in flood control planning would be able to apply a pair of digital computer programs known as the University of Kentucky Flood Control Planning Programs to ease the computational burden of evaluating specific flood control situations. Program II determines the economically optimum combination of channel improvement, land use restriction, and flood proofing for flood damage abatement. Program III also incorporates reservoir storage into the planning process. The Programs are not intended to provide a finished design but rather to select the optimum combination of flood control measures …

The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James

KWRRI Research Reports

It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

If reservoir storage is to be considered in a flood control program, it is necessary to …

Antelope Creek, Dead Mans Run And Middle Creek: Salt Creek Basin, Volume Ii: Summary Report, United States Army Corps Of Engineers, Omaha District

United States Army Corps of Engineers, Omaha District

Antelope Creek and Dead Mans Run, right bank tributaries of Salt Creek, rise within the Lincoln metropolitan area near the town of Cheney, and 84th and A Streets, respectively. These streams flow in a northwesterly direction and drain 14 and 10.5 square miles, respectively. Middle Creek, a left bank tributary of Salt Creek, rises in eastern Seward County and drains 100 square miles as it flows in an easterly direction to join Salt Creek in Lincoln. Urban development in these valleys is concentrated within the Lincoln city limits. Elsewhere the valleys are rural in character, with the land devoted to …

Antelope Creek, Dead Mans Run And Middle Creek: Salt Creek Basin, Volume Ii: Technical Appendix, United States Army Corps Of Engineers, Omaha District

United States Army Corps of Engineers, Omaha District

This report on Antelope Creek, Dead Mans Run, and Middle Creek is the second in a series of flood plain information reports being prepared for streams in the Lincoln, Nebraska metropolitan area. Volume I of this series, published in August 1964, described flood hazard areas of Salt Creek Haines Branch, and Beal Slough.

This Technical Appendix, covering Antelope Creek, Dead Mans Run, and Middle Creek, is presented in four sections. Section A presents information applicable to all three streams. Sections B, C, and D are devoted to information applicable to the individual streams.

Economic Analysis Of Alternative Flood Control Measures By Digital Computer, Thomas M. Rachford

KWRRI Research Reports

The purpose of this project was to develop a digital computer program for selecting the optimum combination of flood proofing, flood-plain land use, channel improvement, and residual flood damage for a given floodplain. Based on economic efficiency, the optimum policy is selected for each planning unit of the total flood-plain for each period of time called a planning stage. The program was written in Fortran IV for the IBM 7040 and the University of Kentucky Computing Center compiler. The program requires about 23,000 words of core storage and about 30 seconds of execution time per planning-unit-stage for typical conditions. The …

Thunderstorms And Tornadoes Of February 1, 1955, Jean T. Lee

National Oceanographic and Atmospheric Administration: Technical Reports and Related Materials

The purpose of this paper is to describe and illustrate some of the features that are of particular interest in the forecasting of one of the most death-dealing series of convective storms of the 1950s that occurred during the afternoon and evening of February 1, 1955. This series of severe storms included tornadoes, destructive winds, hail, and heavy rain that first struck near Marianata, Arkansas, then roared through Commerce Landing, Mississippi and northern Mississippi. then moved on to near Huntsville, Alabama.

Includes features at the surface, at 850 mb, 700 mb, and 500 mb, and upper air conditions, along with …
