Summary: Enid Dam, a unit in the flood-control plan for the Yazoo River, is a rolled-fill structure about 85 ft high and 8400 ft long, and contains about 5-3/4 million cu yd of fill.

The purpose of the assessment is to provide background information on the Corps' practices, identify shortcomings in specifications, estimates, grout placement techniques, and, in general, to determine the effectiveness of the Corps' grouting programs. The report reviews past grouting projects and describes the planning, execution, and performance evaluation of the programs.

"The objectives of this report are as follows: (a) To present the design and details utilized on the precast concrete panel rehabilitation at Troy Lock. (b) To compare the results of precast concrete panel rehabilitation with previous cast-in-place repairs, with respect to quality, cost, and schedule. (c) To recommend refinements in the details and methods of fabrication and erection of the precast panels, based on lessons learned from work performed at Troy Lock." (p. 2).

The purpose of the investigation reported herein was to develop data on the suitability of Prepakt concrete for mass concrete dams and for reinforced concrete construction. Prepakt concrete is made by packing the forms with coarse aggregate and then pumping in a cement base intrusion mixture (grout) to fill the voids.

This report provides a review of the design and performance of the embankment and foundation of Blakely Mountain Dam in Arkansas. "This study is one of a series of similar studies of the foundation and soil mechanics features of earth dams [...] In these studies field experience is analyzed and performance of the completed structures is compared with design predictions to provide information for use in the design and construction of future projects" (p. 1).

Report on model tests related to drainage structures for the Tennessee-Tombigbee Waterway to provide recommendations about construction.

Preface: The study was initiated in early 1951 to develop methods of predicting the moisture content of several soils in the vicinity of Vicksburg, Mississippi.

This report documents the results of a site investigation conducted to support free-field ground shock calculations and field operations for Project MIDDLE GUST, Events I, II, and III. The site is characterized by a 6- to 9-ft-thick section of sandy clay (CL) and clayey sand (SC) overburden overlying almost 500 ft of clay shale of the Pierre Formation which overlies older sedimentary rocks. A perched groundwater table in the overburden, approximately 4 ft below the ground surface, is fed by water from the Colorado Canal, which borders the site on three sides.

This report describes a study to measure redistribution in sand due to cyclic shear and gyratory shear including descriptions of the apparatus and equipment, with shop drawings; test procedures; test results; and discussion of the study and findings.

From foreword: This report covers one phase of a comprehensive study to determine the relationship between the trafficability of soils and the mobility of military vehicles.

From abstract: "This report develops a process for the selection of areas appropriate for artificial marsh construction using dredged material. By application of the methodology set forth, Engineer District personnel will be able to efficiently identify such areas...The selection rationale is tested in Volume II by the choice and description of 50 prime candidate project areas, 10 within each of five major coastal geographical regions. From this compilation, 10 optimum project areas, two in each geographical region, were selected and described further using data gathered in project areas and from relevant Engineer Districts."
