Rainfed Agriculture and Slope Gradient Interactions in Soil Erosion and Redistribution Using 137Cs |
|
| چکیده انگلیسی مقاله |
Understanding the processes of displacement and redistribution of soil particles caused by different erosion types is considered as an efficient sediment management tool in various scales from the field plot to the watershed. Due to the effective role of plowing on surface roughness, soil structure, the rainfed agriculture on high gradient slopes is one of the main sources of accelerated soil erosion. Therefore, the present study aimed to investigate the synergistic effect of rainfed agriculture and slope gradient on soil erosion using 137Cs in Khamsan experimental watershed, western Iran. The distribution map of soil erosion and deposition of the watershed was prepared using 137Cs method and the interactions between rainfed agriculture and slope gradient (as the most effective geomorphological factor) on erosion rate and sediment redistribution were evaluated. The results indicated that the highest rates of soil erosion in rainfed agriculture (11.46 ton.ha-1yr-1) and rangeland (1.27 ton.ha-1yr-1) was recorded in the slope classes of 20-30% and >60%, respectively. In addition, the maximum sedimentation in rainfed agriculture (5.78 ton. ha-1yr-1) and rangeland (0.89 ton. ha-1yr-1) occurred in the slope classes of 30-60% and in >60%, respectively. |
