Present And Prospective Technology For Predicting Sediment Yield And Sources

Excerpt from Present and Prospective Technology for Predicting Sediment Yields and Sources: Proceedings of the Sediment-Yield Workshop, Usda Sedimentation Laboratory, Oxford, Mississippi, November 28-30, 1972 This publication contains papers presented at the sediment-yield Work shop sponsored by 'the usda Sedimentation Laboratory, Oxford, Miss, on N ovember 28 - 30, 1972. The meeting was originally planned as a workshop between Agricultural Research Service and Soil Conservation Service per sonnel. However, because of an intense show of interest the meeting was broadened to include representatives of other Federal agencies, State groups, universities, and consulting firms. About 150 participants - soil scientists, engineers, geologists, and sediment chemists - attended. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This new edition of Soil Erosion Research Methods retains the themes and layout of the first edition. However, most chapters have been revised and some additional chapters have been added. There are new chapters on modeling wind and water erosion. Extensive revisions and updating have been done in chapters dealing with assessment of erosivity and erodibility, erosion, crop productivity, measuring sediment yield from river basins and field plot techniques. There is extensive updating of current statistics on the global magnitude of soil erosion by water and wind and on denudation rates. Several new authors have made significant improvements in revising and updating available information.

Since its introduction in 1979, CHEAPO, a computer based economic analysis program, has allowed users of the Stand Prognosis Model to evaluate silvicultural alternatives from an economic point of view. Subsequent modifications to the Prognosis Model have rendered CHEAP0 obsolete. This users guide covers a new computer model, CHEAP0 II, which is compatible with version 5.1 of the Prognosis Model and expands its economic analysis capabilities.
