Simulating the Effect of Land Use/Land Cover Changes on Soil Erosion Using RUSLE model and Google Earth Engine in Karkheh Basin, Iran |
|
| چکیده انگلیسی مقاله |
Soil erosion by water is a natural process in which particles are separated from the land surface and transported. In terms of managing and planning soil conservation in the revised universal soil loss equation (RUSLE), factors C and P are the most important and dynamic components at different time scales. This study aims to simulate the effect of land use/land cover changes on soil erosion using the RUSLE model in the Karkheh basin using remotely sensed data and geographic information systems. Time series of MODIS products, MCD12Q1 and MOD13Q1, 10-minute rainfall intensity data, soil properties, and digital elevation model were used. The results indicated that the average long-term soil erosion of the whole basin was 14.7 ton. ha-1 yr-1, and the average amount of soil erosion in its sub-basins was varied between 0.1 (Azadegan plain sub-basin) to 34.2 ton. ha-1 yr-1 (Cheghlvandi sub-basin). The results also revealed that the average trend of soil loss in this basin in the last two decades has been decreasing and in 2018 has reached its minimum level of 14.2 ton. ha-1 yr-1. The general results of this study showed that by dynamically considering the LULC from 2001 to 2018, the average annual rate of soil erosion changed by about 5%. |
