New Test Method for Determination of Saturated Hydraulic Conductivity of Field Soils by Sealed Single-Ring Infiltrometer and Multiple Pressure Head Procedure

1. Scope

2.1 Scope The scope of the Committee shall be: The promotion of knowledge; stimulation of research; the development of specifications and methods for sampling and testing; and the development of terminology, definitions, and practices relating to the physical and chemical properties and behavior of soil, rock, and the fluids contained therein. Included are the physical and chemical properties and behavior of: soil-like materials and fluids occupying the pore spaces, fissures and other voids in soil and rock insofar as such fluids may influence the properties, behavior and uses of the soil and rock materials. Excluded are the uses of rock for building stone and for constituent materials in portland cement and bituminous paving and structures coming under the jurisdiction of other committees of the Society.

2.2 Interest Area The areas of interest of the Committee are soil, rock, powders, and such materials that may be intimately associated with soil and rock. . It will be the policy of this Committee to avoid, insofar as possible, dealing with methods of design of engineered structures and all those features of general practice in the use of soil and rock which may not involve the development of standards. It will, however, be considered within the scope of the Committee's work to promote by every desirable means the close cooperation of other organizations and committees whose field of endeavor is closely allied to that of the Committee.

Rationale

There is new technology available for measuring field saturated hydraulic conductivity (Kfs) that have advantages over the traditional methods. These newere methods simplify the measurements and improve the accuracy of the measurement. There are only a few standards that apply to the field measurement of Kfs. 5.3 The simplicity of the procedure with the automated sealed single-ring infiltrometer allows for increased Kfs data collection compared to current standard methods (D3385 and D5093). Spatial variability of Kfs at test sites can be determined. 5.2 These data are particularly useful in, but not limited to, the fields of soil science, geotechnical engineering, civil engineering, environmental engineering, agronomy, and hydrology.

The title and scope are in draft form and are under development within this ASTM Committee.
