Book Description
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.

Book Description
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.
