This book was released on 1987 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted in response to a problem definition workshop held in April 1984 for the Repair, Evaluation, Maintenance, and Rehabilitation (REMR) Research Program, Rehabilitation Alternatives to Control Adverse Effects of Levee Underseepage. The following research need was determined to have one of the highest priorities: Emergency flood flight guidance for observing underseepage and employing remedial actions. Documented in this report are the basic levee inspection responsibilities and flood fighting techniques of the Mississippi River Valley Districts (Rock Island, St. Louis, Memphis, and Vicksburg) and the Levee Boards. The need for a consistent terminology for the severity of underseepage, better flood fight training for young engineers, and better mobility for inspection were the main problems identified in this report. The following terminology is recommended as a standard to describe the severity of underseepage: Light - area is wet; Moderate - running water is observed; Heavy - pin boils (small pipe openings without sand cones) with running water; Sand boils - any pipe opening with sand cones; Large boils - sand boils with pipe openings 12 inches or more in diameter (size described by diameter of pipe opening).

Available in PDF, EPUB and Kindle. Book excerpt: The Federal Government through the U.S. Army Corps of Engineers (USACE) has a large investment in flood-control levees. Where such levees are built on pervious foundations, seepage beneath the levee (underseepage) during floods can produce pressure and flow conditions capable of initiating subsurface erosion leading to levee failure. Two adverse phenomena may occur; one is sand boils which involves the movement of subsurface sand to the surface by flowing water, and the other is heaving which involves the upward movement of a relatively impervious surface layer resulting from subsurface water pressures in excess of its weight. To prevent such occurrences, the USACE has developed a set of procedures to analyze underseepage conditions on a site-specific basis and a set of procedures to design underseepage control measures. For the most part, these procedures were developed in the 194Os and 1950s. Intensive construction of control measures was accomplished in the 195Os and l96Os. Several moderately large and major floods have provided data from which the validity of the procedures and the security of the constructed system can be inferred. Also, since the 195Os many technical advancements have been made in engineering analysis techniques and construction methods that may merit application to underseepage problems.
