Purpose: Sediment delivery from headwater catchments to reservoirs is a serious threat to reservoir sustainability, and is a critical issue in Mediterranean environments where water resources are scarce. In this study we assessed the consequences of two landscape management scenarios (natural vegetation recovery and scrub clearance) on soil erosion and sediment yield. The results were analyzed ...
Investigation about the influence of land-cover and land use changes on soil erodibility potential, case study: Gharesou, Gorganrood Land use and land cover (LUC) change associated with climatic and geomorphologic conditions of the area have an accelerating impact on the land degradation. Natural as well as human-induced land use land cover change (LUCC) has significant impacts on regional soi...
Soil erosion will have impact in the land productivity, water resource and watershed as a whole. The loss of top soil leads to degradation for an agrarian area like Jhimruk which also known “The rice bowl Nepal”, it would be huge consequence on productivity. Therefore, is essential know spatial distribution areas susceptible assess potential plan effective mitigation measures. Revised Universal...
â increase in wastage of soil resources in watershed is a persistent challenge that with increase in population and pressure on natural sources and unstable plantation on gradient farms and soils cause production reduces on farms, and also decrease in daily ratio of farms to population can cause more pressure on lands and natural resources.lavarefin watershed placed in 60 km from bandarabass in...
soil erosion is a serious environmental problem in vazroud watershed, which is located in the centre of the mazandaran province, iran. unfortunately, vazroud watershed like most iran watersheds don’t have recorded data and erosion and sedimentation gages to research, monitor and model soil erosion at large watershed. in order to assess the soil erosion risk, soil erosion modeling at the watersh...
Soil erosion is one of the most common types land degradation. To provide useful information for proper management, quantitative soil evaluation and identifying influential factors are needed. However, rare studies have been reported on spatial modeling in connection with affective to prioritize locality type control measures. Hence, aim this study was (1) assess erosion-prone areas Talar water...
مدلسازی میتواند نوعی رویکرد کمی و سازگاری در برآورد فرسایش خاک و تولید رسوب تحت دامنۀ وسیعی از شرایط را فراهم کند. در این مطالعه بهمنظور شناسایی توزیع مکانی خطر فرسایش خاک و تولید رسوب در حوضۀ آبخیز تالار روش یکپارچهسازی معادلۀ جهانی هدررفت خاک اصلاحشده، سامانۀ اطلاعات جغرافیایی و فن سنجش از دور بهکار گرفته شد. عوامل فرسایندگی باران، فرسایشپذیری خاک، طول و درجۀ شیب و پوشش گیاهی بهمنظور ...
