This book discusses basic procedures for soil survey for engineering projects as an aid to engineers, planners, geologists, and other earth scientists. It will be of particular benefit to practitioners in developing countries.
The 6th of a related series sponsored by the Committee on Surveying, Mapping and Classification of Soils. It tabulates useful information on the status of geologic and agricultural mapping in the United States, lists geologists and soil scientists who may be able to assist the engineer in obtaining more precise soil and subsurface information from the interpretation of these special purpose maps, and contains a series of five papers and one discussion on the development and application of soil survey information to the design and construction of highways.
Contains a group of related papers on the use of aerial photographs to abtain terrain information, such as, type of soils, parent material and drainage from the study of airphoto soil and rock patterns. The status of current geologic and agricultural soil mapping are indicated, and revised lists of geologists and soil scientists are given.
The Soil Survey Manual, USDA Handbook No. 18, provides the major principles and practices needed for making and using soil surveys and for assembling and using related data. The term ?soil survey? is used here to encompass the process of mapping, describing, classifying, and interpreting natural three-dimensional bodies of soil on the landscape. This work is performed by the National Cooperative Soil Survey in the United States and by other similar organizations worldwide. The Manual provides guidance, methodology, and terminology for conducting a soil survey but does not necessarily convey policies and protocols required to administer soil survey operations. The soil bodies contain a sequence of identifiable horizons and layers that occur in repeating patterns in the landscape as a result of the factors of soil formation as described by Dokuchaev (1883) and Jenny (1941).
