Soil erosion in watersheds, causing problems such as the loss of agricultural land productivity and reduce soil surface layer, endangering the life of reservoirs and water utilities, loss of soil fertility, increasing flood, threatening human food security, etc. The negative effects of soil erosion, watershed management operations to improve care. According to the extent of the watershed and th...
Background: The 2019 American College of Rheumatology (ACR) guidelines strongly recommend oral nonsteroidal anti-inflammatory drugs (NSAIDs) for management hip and knee osteoarthritis (OA) topical NSAIDs OA. There are, however, important safety considerations with in terms increased rates gastrointestinal, cardiovascular, renal events. Given these risks, it is to understand the characteristics ...
مدلسازی فرآیند بارش-رواناب در حوضههای آبخیز از نظر مدیریت منابع آب، مهندسی رودخانه، سازههای کنترل سیل و ذخیره آن اهمیت ویژهای دارد. تنوع این مدلها انتخاب مناسبترین مدل با توجه به اهداف موردنظر را دشوار میکند. در این تحقیق از مدل یکپارچه IHACRES و مدل نیمهتوزیعی SWAT برای شبیهسازی رواناب حوضه آبخیز خرمآباد با مساحت 2467 کیلومترمربع استفاده شد. بعد از همپوشانی لایهها، 232 واحد پاسخ هی...
This study aims to simulate runoff and runoff quality of Zarrineh river basin by SWAT model. Calibration and verification were done respectively with monthly runoff statistics in SWAT CUP by SUFI2 method for 1992-2013, for 12 sub basin, 226 HRU and monthly nitrate data for 2006-2009. The highest runoff sensitivity and runoff quality with minimum Pvalue and maximum absolute value Ttest belong to...
Forest water conservation function is an important part of forest ecosystem services. The discontinuous distribution forests in semiarid areas brings difficulties to the quantitative evaluation functions at basin scale. In this paper, we took upstream Xiong’an New Area (Zijingguan—ZJG, Zhongtangmei—ZTM and Fuping—FP basins) as example combine soil assessment tool (SWAT) balance method calculate...
