Soil water balance has response to climate change and evaluation of soil water change is one of the most important items of climate change impact assessment. GCM outputs under three scenarios were statistically downscaled during 2010~2039 to simulate the potential change of soil water balance in Wangdonggou watershed on the Loess Plateau with WEPP model. GCM predicted a 1.8 to 17.5% increase in...

Distributed watershed hydrological and erosion modeling is gaining popularity in recent years due to increased computing power and availability of detailed spatial hydrological data. Models of this type are widely believed to provide greatest opportunities to examine hydrologic impact of land use change and climate change (Sharika et al. 2000); they also have immense utility to forecast the mov...

Irrigation furrows allow detailed study of sediment transport relationships because of gradually decreasing flow rates in long, uniform, ...

Equations used to calculate erodibility in the Water Erosion Prediction Project soil erosion Ž . model WEPP are based on erodibility studies in the USA and may not function well in another Ž . region. This study was conducted to: i analyze erodibility and infiltration characteristics of some Ž . predominant soils of southern Spain, and ii test equations used to calculate interrill erodibility i...

شرایط افروزش و اشتعال سوخت‌های گداخت هسته‌ای در حضور ناخالص­‌ها، یکی از موارد مهمی است که طراحی قرص‌های سوخت باید مورد توجه قرار گیرد. این مقاله اثر ناخالصی هسته سنگین طلا بر کلیه فرایندهای احتراق پلاسمای غیرتعادلی دوتریم- تریتیم مدل چهار دمایی آن شکل تابع توزیع انرژی رفتار فوتون‌ها تأثیر می‌گذارد بررسی گرفته است. مطالعه شامل اثرات منفی سوخت، طول زمان تشکیل لکه داغ نتایج محاسبات عددی به­ دست آم...
