Abstract: This report contains the results of four studies pertaining to shotcrete technology.

Abstract: The general objective of this research is to develop methods for analysis of stresses and movements in embankments.

A bibliography for the investigation of the hydraulic regime and physical nature of bottom sedimentation at the Columbia River dump site.

Partial abstract: "The principal subjects of the report are the often neglected changes in the interaction of soil and pressure cells with consequent changes in relative errors in cell registrations. The report contains (a) a brief account of the development and use of soil pressure cells; (b) a review of proposed theories for soil-cell interaction; (c) a delayed account of tests with Waterways Experiment Station pressure cells placed in a large triaxial device; and (d) tentative conclusions plus suggestions for calibration, installation, and measuring procedures."

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

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."

Abstract: "Results of an investigation conducted to determine the engineering feasibility of using dredged material to expand an existing marshland area are presented. Dredged material obtained from maintenance dredging operations was found suitable for use as marsh substrate and site conditions were found adequate for construction of a containment facility. Factors evaluated in the study include site-specific feasibility of marsh expansion using dredged material, sizing of the demonstration area to meet water-quality and storage needs, preliminary design of the containment facility, procedures for the placement of dredged material, and identification of alternative construction methods, materials, and costs. Overall feasibility of marsh expansion was demonstrated and additional investigations were recommended for the project."
