abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

BACKGROUND AND OBJECTIVES: The study explored the capability of the geographic information system interface for the water erosion prediction project, a process-based model, to predict and visualize the specific location of soil erosion and sediment yield from the agricultural watershed of Taganibong. METHODS: The method involved the preparation of the fou...

• A methodology to select climate models model future soil erosion is proposed. under land use changes The most likely best- and worst-case scenarios are developed. Results show that will increase the mean of scenarios. Winter wheat an economically viable option reduce erosion. Soil by water from arable poses a serious threat on-field agricultural productivity wider environment through off-site...

wepp model needs a great deal of input data.  identifying the model’s sensitive parameters and their prioritization increases the accuracy and efficiency of the model. on the other hand, wepp model can simulate processes affecting on runoff, erosion and sediment throughout the year. thus, model sensitivity must vary based on the storm occurrence time and parameters value in different sections o...

The purpose of this Special Issue is to provide an opportunity for researchers publish novel results that could help landowners, land-users, farmers, politicians, and other representatives our global society protect, and, if possible, improve the quality quantity precious soil resources. Authors were encouraged submit papers related new ways mapping, showing more detailed input data, modeling r...

Soil erosion and sediment yield from watersheds confine sustainable use of land resources and is supposed as one of the most critical environmental issues. Prediction of storm wise soil erosion and sediment yield is very important, especially in arid and semiarid regions due to small number of events and high intensity of rainfall. Evaluation of soil erosion by existing models is needed as an i...

Danjiangkou reservoir area is the main water source and the submerged area of the Middle Route South-to-North Water Transfer Project of China. Soil erosion is a factor that significantly influences the quality and transfer of water from the Danjiangkou reservoir. The objective of this study is to assess the water erosion (rill and sheet erosion) risk and dynamic change trend of spatial distribu...

[1] The fate of soil organic carbon (SOC) transported and redistributed by erosion over steep agricultural landscapes is uncertain. The effect of topography, slope, and slope position on SOC redistribution must be considered. Our objectives were to (1) determine the spatial patterns of both tillage and water erosion-induced SOC redistribution, (2) evaluate the compensating effects of tillage-in...
