Abstract
Evaluation of the effects of soil and water protection operations on soil characteristics, erosion and sedimentation in the Rimele watershed of Lorestan province
Abstract
Introduction
Evaluating the effectiveness of various water and soil protection measures on soil properties and erosion and sedimentation is of great importance in soil planning and management. And it is considered to be one of the measures of moving towards sustainable development. Based on this, this research has evaluated the effects of water and soil protection measures in terms of erosion and sedimentation and soil characteristics in the Rimele watershed of Lorestan province.
Materials and methods
EPM model was used to predict erosion before and after the implementation of water and soil protection measures. In order to investigate the characteristics of the soil, the apparent specific mass factors, soil texture, acidity, electrical conductivity and soil permeability were evaluated at two depths of 0-30 and 30-60 cm.
Results
The results of comparing the physical and chemical properties of soil in two areas under protection operation and the control area, showed that with water and soil protection measures, the apparent specific gravity, soil texture, acidity and electrical conductivity of surface soil did not increase significantly. The comparison of permeability data in control areas and protected areas showed that the implementation of water and soil protection operations had a positive effect on soil permeability. Also, the amount of total annual erosion and sedimentation in the current conditions compared to before the implementation of water and soil protection measures have decreased by an average of 6793 cubic meters and 5712 tons, respectively. The results of the paired t-test showed that the water and soil protection measures implemented in the Rimele basin have been able to create a significant difference in reducing erosion and sedimentation.
Conclusion
According to the findings of the research, it can be stated that water and soil protection measures have a significant positive effect in reducing erosion and sedimentation, but its effect on improving soil quality is not absolute and is completely dependent on the different climatic and geological conditions of each region.
