Estimating the critical slope angle (CSA) for sheet erosion is important precision estimation of and development control practices. This study developed mathematical equations considering rainfall intensity soil infiltration to efficiently estimate both instantaneous (at a given instant during rainfall) cumulative CSAs, while also providing valuable explanation change in CSA. The were consisten...

In the United States, the USDA Natural Resources Conservation Service (NRCS) is the primary agency charged with the task of reducing wind erosion associated with production agriculture. The NRCS has used the Wind Erosion Equation (WEQ) (Woodruff and Siddoway, 1965) to assess the effects of field management on the potential for wind erosion for the last two and a half decades. The WEQ uses input...

Estuaries are submitted to a natural filling caused by the settling of cohesive sediments ( < 63 μm). Those sediments, coming mostly from the sea, are transported in estuaries by the tidal currents during ebb and flood flows. During slack water, fluid velocities vanish and particles are no more suspended by turbulent dispersion. Sediment particles settle towards the bottom, and then deposit on...

in iran due to the lack of long experience in the implementation of soil conservation and watershed management plans, these measures have not been evaluated quantitatively and specific methods for this purpose have not been provided. in this research effort is to investigate the effect of watershed management operations performed in can basin in 1379, on the amount of erosion and sedimentation ...

Modeling soil erosion, sediment yield, and runoff are crucial for managing reservoir capacity, water quality, watershed productivity. However, the monitoring modeling of erosion sedimentation rates in developing countries such as Ethiopia is not well practiced; thus, capacity diminishing at faster rates. In this study, Megech watershed, Upper Blue Nile Basin, were modeled using physically-based...

Wind erosion not only affects agricultural productivity but also soil, air, and water quality. Dust and specifically particulate matter ≤10 μm (PM-10) has adverse effects on respiratory health and also reduces visibility along roadways, resulting in auto accidents. The Wind Erosion Prediction System (WEPS) was developed by the USDA-Agricultural Research Service to simulate wind erosion and prov...

In recent decades, water erosion potential has been recognized as a severe threat against soil sustainability and resources. The present study was conducted to investigate the relation between geomorphometric parameters type simulate in Emamzadeh watershed located northeast of Khuzestan Province. primary secondary geomorphic parameters, including slope, plan curvature, profile flow length, accu...
