The purpose of this manual is to describe and explain the use of the "Unified Soil Classification System" in order that identification of soil types will be on a common basis throughout the agencies using this system.

Report describing various kinds of soils and their characteristics, for use in constructing embankments and foundations: "The major properties of a soil proposed for use in an embankment or foundation that are of concern to the design or construction engineer are its strength, permeability, and consolidation and compaction characteristics. Other features may be investigated for a specific problem, but in general some or all of the properties mentioned above are of primary importance in an earth embankment or foundation project of any magnitude" (p. 1).

Report on tests of permeability and triaxial of mass concrete as well as tests of permeability, pore pressure, and uplift in gravity dams.

"This report contains a summary of construction of procedures and field observations made during and after construction of Benbrook Dam, a brief review of the original design data, and comparisons of design predictions with performance data" (p. 1). It is part of a series to compare field experience and performance of existing structures with design predictions.

This report provides a summary and analysis of field observations and performance of the Tom Jenkins Dam in Ohio, compared with original design predictions.
