سیل از جمله مخاطرات ناشی از تغییرات اقلیمی و کاربری اراضی در اکثر نقاط دنیاست که سالانه خسارات بسیار زیادی بر جوامع تحمیل میکند. برای مدیریت و پیشبینی سیل خیزی یک منطقه، تخمین پتانسیل ارتفاع رواناب نقش مهمی دارد؛ در این راستا سازمان حفاظت خاک آمریکا (SCS) یکی از مؤثرترین روش ها را ارائه داده است که برای حوضه های فاقد آمار بسیار مناسب میباشد. مطالعه ی حاضر نیز با هدف محاسبه و تحلیل پتانسی...
The present study was conducted in Baitarani basin up to Anandapur gauging station of Odisha covering an area 8603.7 km2. Pre-processing from digital elevation model (DEM) done using HEC-Geo-HMS extension and spatial analyst tool ArcGIS. These pre-processed files were then imported HEC-HMS for simulating runoff. In this study, runoff simulation two methods, viz., composite distributed curve num...
Analysis of vegetation-based management scenarios using MCDM in the Ramian watershed, Golestan, Iran
This research has concentrated on the physical and socio-economic impacts of vegetation-based management scenarios targeting on flooding and soil erosion issues in the Ramian watersheds. The Ramian watershed with an approximate area of 24000 ha is located in Golestan, Iran. For each sub-watershed, four biological actions (activities) and 16 management scenarios have been considered. Physical im...
The soil and water conservation structures are constructed to overcome scarcity as a result of interannual rainfall variability paucity the perennial source water. present study was aimed estimate design runoff for efficient hydrologic various soils using machine techniques enabling harvesting available with economical which can support in developing climate resilience Saurashtra region Gujarat...
Evaluation of soil loss estimation using the RUSLE model and SCS-CN method in hillslope mining areas
infiltration and its modeling are important in design and implementation of irrigation projects, drainage, water-resources management, soil-conservation, hydrological studies, and artificial-recharge of groundwater and are influenced by different characteristics of soil and infiltrated water including the amount of salinity and sodium. the aim of this study was to evaluate the infiltration mode...
