This book was released on 1972 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pumping tests, chemical and biological analyses of water samples, and well screen inspection by means of a borehole TV camera were conducted in 1969 as part of a study of the efficiency of the relief well system along the Mississippi River between Alton and Gale, Illinois. The purposes of this study are to determine the extent and causes of well deterioration and to investigate methods for improving and maintaining the efficiency of the well system. The relief wells were designed by personnel of the U.S. Army Engineer Waterways Experiment Station and built under the supervision of the U.S. Army Engineering District, St. Louis (SLD). The wells included in this investigation were installed between 1953 and 1955. Since then, SLD has performed a series of well pumping tests, periodically inspected the relief well system, and observed the operation of the wells during high river stages of the Mississippi River.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The studies and data presented in this report are the result of the combined efforts of the Memphis, Vicksburg, and New Orleans Districts and the Waterways Experiment Station, under the general direction of the Mississippi River Commission. These studies have included a review and compilation of all underseepage reports made during and since the 1937 high water; exploration and geological studies of numerous sites where underseepage was a serious problem in 1937; installation of piezometers at selected sites to measure substratum pressures beneath and landward of levees; field pumping tests to determine the permeability of the sand aquifer at certain sites; theoretical, electrical- analogy, sand model, and prototype studies of relief wells, partial cutoffs, and landside berms for the control of underseepage; and observation and measurement of natural seepage at certain locations during the 1950 high water.

This book was released on 1964 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1940 the Mississippi River Commission initiated a comprehensive study of under seepage and its control along the Lower Mississippi River levees. The purpose of this study was to provide data on the relation of soil conditions, geologic features, and underseepage and to improve methods for analyzing subsurface seepage. One phase of the investigation consisted of installation of piezometers at selected sites along the Lower Mississippi River to obtain data on the development of substratum hydrostatic pressures, and distances from the levee to the effective source of seepage entry. Analysis of piezometric data was based primarily on the 1950 high-water data.
