آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولDetermination of Main Agents Affecting Soil Erosion in Rainfed Land of Kermanshah Province Using Rainfall Simulator
In recent decades, low-yielding rainfed farms have become known as the main sources of sediment production and soil erosion in the country. Therefore, more research is needed on the factors affecting erosion and sediment production in these areas. This research was carried out with the aim of studying the effects of slope and rainfall intensity on erosion between rainbow trout in test farms in ...
متن کاملErodibility of road batters under simulated rainfall
Rainfall simulation experiments on road batters in a forest catchment in New South Wales, Australia, demonstrated the limits of small scale erosion studies. Comparable erodibility studies were carried out on road surfaces, road batters constructed of soil, bedrock and unconsolidated materials and the forest surfaces. There was no significant difference in sediment loss between any type of site,...
متن کاملRunoff and Soil Erosion Assessment on Forest Roads Using a Small Scale Rainfall Simulator
Forestry operations can significantly alter hydrological and erosional processes in a catchment. In the course of developing timberland, a network of persistent roads and skid trails causing soil compaction is usually established. Hereby, the infiltration rate of the soil is distinctly reduced, which leads to the generation of overland flow—this may also cause soil erosion. In this study, a sma...
متن کاملMeasure Soil Erodibility in Situ
The assessment of the erodibility of soil materials is essential for analyzing and modeling rill, gully, streambed, streambank, spillway, and embankment erosion. A submerged jet−testing apparatus has been developed and used for characterizing soil erodibility in several applications as cited in the literature. The apparatus has been developed based on knowledge of the hydraulic characteristics ...
