The higher rate of slope erosion in the Himalayan basins is contributing to rapid change landform mountainous terrain, which has caused sedimentation, and inundation downstream. Tamakoshi basin a trans-boundary river that originates from Tibet flows through Dolakha Ramechap districts before joining Sapta Koshi river. Few studies exist Nepal attempting quantify susceptibility. However, they are ...

Soil erosion is a globally challenging issue that hinders agricultural productivity by enhancing land degradation and loss to the top fertile soil. Although it global issue, its effect adverse on farmers dwell in developing countries. Hence, providing information soil crucial plan implement appropriate water conservation measures. Accordingly, estimation models were developed grouped as empiric...

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, a...

Soil erosion is one of the most severe forms land degradation, which has a wide range adverse on-site and off-site impacts in highlands Ethiopia general study area particular. The objective this was to estimate soil erosion, identify prioritize hotspot microwatersheds Antsokia-Gemiza district. Revised Universal Loss Equation (RUSLE) used potential annual loss. Geographic Information System (GIS...

Soil erosion is an important environmental problem that can have various negative consequences, such as land degradation, which affects sustainable development and agricultural production, especially in developing countries like Tunisia. Moreover, soil a major around the world because of its effects on fertility by nutriment loss siltation water bodies. Apart from this, most serious type severa...

سابقه و هدف: ورود گونه­­ های ماهی مهاجم دراکوسیستم ­های آبی، سبب بروز انواع اثرات منفی اکولوژیکی اقتصادی-اجتماعی می ­­شود. اولین گام در تجزیه تحلیل مخاطرات ناشی از گونه­ غیر­بومی، شناسایی خطر است بر این اساس ابزارهای متعددی برای ارزیابی خطرات تهاجمی غیربومی به منظور پشتیبانی تصمیم گیرندگان گونه ­­ها ایجاد شده است. هدف پژوهش قدرت تیلاپیای شکم قرمز (Coptodon zillii) حوضه آبریز تالاب شادگان (حوضه‌...

هدفت هذه الدراسة إلى تطبيق نموذج المعادلة العامة لفقدان التربة (RUSLE) لتقدير قابلية للتعرية في حوض وادي بريشو، الواقع الشمال الغربي من قضاء ئاكرى . واتبع الباحث دراسته المنهج الاستقرائي للمعطيات المختلفة ليتبلور خلال متغيرات منها: الارتفاع الرقمي (DEM)، بيانات خصائص ، والمرئية الفضائية (Landsat8)، والبيانات المناخية، ثم انتقل التعامل معها بيئة نظم المعلومات الجغرافية (GIS) عبر برنامج (ArcMap 1...

Abstract Flat lakes with a large catchment area are especially affected by sediment inputs. The Kolleru Lake (south-eastern India) surface of approximately 6121 km 2 belongs to such types lake basins. study’s main objective was the assessment both soil erosion and yield concentration rate catchment. study conducted using revised universal loss equation (RUSLE) model due its simple good applicab...
