Abstract

Background and Objectives: Soil erosion is one of the most serious and irreversible threat for the sustainable development in each region. Cesium has been produced due to nuclear testing in the last decades and entered into the stratosphere and then comes to the soil by rainfall. These radionuclides have an importance in Soil erosion studies because it is absorbed by the clay soil in a way that it is exchanged hardly. Materials and Methods: This study was conducted to investigate the use of 137Cs in measuring the rate of Soil erosion and distribution of sediments in forest and unforest soils and on different parent material. So, six regions (three in forest with loess, Jurassic material, alluvium loess and other in cultivated area) were selected. Samples were taken from surface to 100 cm depth. Results: Results showed that 137Cs had progressed from surface to depth of 40 cm in these soils. The vertical distribution of Cs in soil profiles under forest Land use indicated that Cs concentration decreased with increasing depth, indicating the stability and non-permeability of the soil, while the Cs concentration changed irregularly with increasing depth in cultivated soils. Also, soil organic matter had a positive correlation with Cs at level 5%. The average rates of Soil erosion are estimated between 18 and 47 t ha-1 y-1 at the different Land use. Conclusion: Generally, it can be concluded that Cesium 137 could be considered as a high accuracy and fast method to estimate soil loss and sedimentation. It is also possible to measure the Soil erosion rate over a period of several years.
