Use of caesium-137 as a tracer of erosion and sedimentation: Handbook for the application of the caesium-137 technique. UK Overseas Development Administration research scheme R4579

Abstract

The caesium 137 technique has become an important tool for investigating soil erosion. It permits retrospective assessment of medium-term erosion rates. The application of the technique requires only one field visit, and the results can be provided within a relatively short time. The soil redistribution rates estimated represent an average for the last 30-35 years, and are therefore less influenced by extreme events. The rates estimated represent the sum of all erosive processes. Both rates and patterns of soil redistribution may be quantitatively assessed. A range of erosion estimates may be obtained, including mean rates of erosion and deposition and net rates of soil export from the field. The whole field may be studied without disturbance to the slope environment. The spatial resolution of the data obtained is defined by the sampling strategy. Chapters of part 1 discuss the basis of the {sup 137}Cs technique, the potential for its further development, and define a protocol for its application. Part 2 includes descriptions of case studies from China, Zimbabwe and Lesotho, which illustrate the value of the {sup 137}Cs technique in the assessment of soil erosion.
