Abstract Side scan sonar is a common tool for seafloor imaging and surveying due its efficiency high resolution. The backscatter information from side enables to identify sediment types seabed roughness, often used study dynamics. Theory suggests that can be correlated the geotechnical properties of surface. This could enhance prediction erodibility characterization, considering offer large spa...
Understanding erosion and sedimentation processes along the drainage network, from hillslopes to rivers reservoirs, is essential for water resources management river restoration. This work proposes a novel dynamic evaluation of landscape factor modeled runoff rates physically-based distributed hydrological modelling, estimate event-scale sediment connectivity. Four precipitation events moderate...
The aim of this research was to determine some erodibility factors, aggregate stability, structure stability and crust formation, in soils located at Ilgaz National Park generate their spatial distribution maps using fifteen different interpolation models GIS medium. For aim, total 151 soil samples were collected from surface (0-20 cm) depth. According analysis results, it determined that most ...
As an important type of soil erosion, freeze-thaw erosion occurs primarily at high latitude and altitude. The overview on the effect was provided. Soil affected by processes, as thawing water reinforce each other. Remote sensing provided unprecedented approach for characterizing timing, magnitude, patterns large-scale changes. Furthermore, essence freeze thaw moisture in pores soil. Freeze-thaw...
Investigation of desertification trend requires an understanding of phenomena that create changes singly or action and reaction together in an area that these changes were led to the desertification and land degradation. In the investigation of pedological criterion affecting on land degradation in Alluvial Fans, first, the map of units was created by overlaying and crossing maps of slope class...
Soil erosion is considered as one of the most significant indices of land degradation, which once evaluated, a wide gamut of changes in the environment could be evaluated. The aim of this study was to evaluate the risk of soil erosion by the application of the CORINE model, as a suitable means of soil erosion assessment, in the semi-arid western areas of Golestan province. In this study, soil, ...
حوضه آبخیز سدمخزنی شهید پارسا در جنوب شرقی شهرستان فردوس استان خراسان واق گردیده است . بااحداث این سد علاوه برآبیاری اراضی موجود، 700 هکتار از اراضی جدید پایین دست به زیر کشت می روند. عمده ترین معضل موجود در رابطه با حوضه آبخیز، وجود بار رسوب فراوان و تجمع آن در پشت مخزن سد می باشد. لذابه علت عدم وجود اطلاعات کافی از وضعیت فرسایش خاک در حوضه آبخیز، دراین رساله بررسی و مطالعه فرسایش پذیری خاک ان...
