نمذجة تعرية التربة لتركيب متين شمال العراق باستخدام GIS&RS

الملخص EN

This study dealt with modeling of soil erosion by estimating the size of erosion and drift and determining its quantities and the areas most exposed to the risk of erosion through the use of the global equation for soil drift (RUSLE) for a solid structure in northern Iraq, with the aim of reducing this problem.

The digital elevation model (DEM) was used, in addition to using space visualizations and calculating the drift equation using GIS and remote sensing software.

While the study concluded that the area has a very high and high classification, which represented an area estimated at (404.9) km2, out of the total area of the basin, which amounted to (684.1) km2, and this means that the study area is exposed to erosion and dangerous soil drift.

It also showed that the most exposed areas for erosion and drift are the most receiving rain and the steepest, as the drift values reached 650 tons / hectare / year, in areas with very high erosion, and technology was of great importance for estimating the size of erosion in the study area; Through the use of remote sensing and geographic information systems to represent the vegetation cover, and then make a layer for each factor of soil erosion and drift.
