Based on the application of Revised Universal Soil Loss Equation (RUSLE) and modern GIS technology (ArcGis 10.2.2.), article presents a method for calculating erosion potential relief (LS) Duruji river basin (north-eastern part Georgia). The most erosion-hazardous areas have been identified, which is approximately 75.1% total area the basin. It has established that special attention should be...
Soil loss is one of the most important causes land degradation. It an inevitable environmental and socio-economic problem that exists in many physiographic regions world, which, besides other impacts, has a direct bearing on agricultural productivity. A reliable estimate soil critical for designing implementing any mitigation measures. We applied widely used Revised Universal Loss Equation (RUS...
Soil erosion is a serious environmental issue in the Gomal River catchment shared by Pakistan and Afghanistan. The river segment between Zam dam diversion barrage (~40 km) brings huge load of sediments that negatively affects downstream irrigation system, but sediment sources have not been explored detail this sub-catchment. analysis flow data shows significant yield still contributing to despi...
The watershed area of the Mangla Reservoir spans across Himalayan region India and Pakistan, primarily consisting Jhelum River basin. is rugged with highly elevated, hilly terrain relatively thin vegetation cover, which significantly increases river’s sediment output, especially during monsoon season, leading to a decline in reservoir’s storage capacity. This work assesses soil erosion risk (Az...
The Garang watershed is one of the main rivers passing through Semarang City, Central Java. uptream mostly a buffer zone and catchment area for water soil resources conservation City surroundings. This research located in upstream watershed, with aim knowing level erosion or loss tolerance due to land use change.The model specific sheet which modeled RUSLE (Revised Universal Soil Loss Equation)...
افزایش هدر رفت منابع خاک در حوزه های آبخیز یک چالش مداوم است که با افزایش جمعیت و فشار وارده بر منابع طبیعی و کشت و کارهای ناپایدار در خاک ها و اراضی شیبدار، موجب کاهش تولید در اراضی گشته و همچنین کاهش روزانه نسبت اراضی به جمعیت ساکن باعث فشار بیشتر بر اراضی و منابع طبیعی شده است.حوزه ی آبخیز لاور فین در 60 کیلومتری شهر بندرعباس در استان هرمزگان قرار دارد و مساحت آن 91/7334 هکتار می باشد. پیش ب...
این تحقیق به منظور بررسی تاثیر تغییرات کاربری اراضی بر هدر رفت خاک در حوزه آبخیز دارابکلا، واقع در استان مازندران انجام شد. مساحت منطقه مورد مطالعه 5727 هکتار و حداقل ارتفاع آن 115 متر و حداکثر آن 681 متر می باشد. در این تحقیق برای تعیین اثر تغییرات کاربری اراضی و هم چنین میزان هدر رفت خاک ناشی از این تغییرات از مدل rusle، (معادله اصلاح شده جهانی فرسایش خاک) و تلفیق تکنیک های سنجش از دور و ساما...
The increasing use and capability of geocomputation tools, as well as increasing availability of land resource information, offer opportunities to utilise such tools for the effective management of information for planning purposes. One among those is the development of spatially-based models that may be used for efficiently undertaking land suitability assessment based on available information...
