Soil Erosion Assessment Using the RUSLE Model, Remote Sensing, and GIS in the Shatt Al-Arab Basin (Iraq-Iran)

In the Shatt Al-Arab basin, soil erosion is a major problem due to steepness of terrain and significant difference in altitude between upstream downstream parts basin. Vast quantities are moved annually, resulting massive repercussions including degradation, structural damage, biodiversity loss, productivity reduction catchment area, huge sediment load, pollution streams rivers. Consequently, assessment risk geographical distribution essential for constructing database developing effective control strategies. Revised Universal Soil Loss Equation (RUSLE) was combined with Remote Sensing (RS) Geographic Information System (GIS) current work define hazard map The RUSLE model included various characteristics zonation rainfall erosivity, erodibility, slope length steepness, land cover management, conservation support practices. Annual rates this study tons per hectare were: extremely high (more than 50); very (50 16.5); (16.5 2.2); medium (2.2 1); low (1 0) ton ha−1year−1 representing 16, 4, 13, 7, 60 % basin’s respectively. loss associated heavy rainfall, loamy predominance, elevated terrains/plateau borders steep side slope, intensive farming.
