in recent years, the occurrence of water and wind erosion indifferent parts of country due to the changes of land use from the forest andpasture into the agricultural and also construction of communication lineshave increased. the study and research on this phenomenon, the effectivefactors in creating them and also identification of geomorphology faciestypes are necessary to prevent the waste o...

IVind ttiimel tests on silty textured loessial soils throtigbout the Cohimhia Plateau of eastern Wa.shiitg{on slate and northern central Oregon were used ro define soil erndibiltiy for wind erosion predictions. Aggregate and primary particle size distributions were determined hy common techniques and correlated wiih the wind tunnel erosion values. Dry aerodynamic particle sizing by a laser meth...

Rain erosion damage, caused by repeated droplet impact on wind turbine blades, is a major cause for concern, even more so at offshore locations with larger blades and higher tip speeds. Due to the negative economic influence of blade erosion, all wind turbine Original Equipment Manufacturers (OEMs) are actively seeking solutions. In most cases, since the surface coating plays a decisive role in...

The main ecological services of the sand-fixed forest are windbreak, soil erosion control, and atmospheric dust retention. In this paper, the ecological services of Populus simonii forest were assessed by simultaneous measurements of wind speeds, daily amount of soil surface wind erosion, and amount of atmospheric dust deposition at different observation sites located within and outside the for...

In this paper work on image analysis methods extracting field boundaries and wind erosion obstacles from aerial imagery is presented. Describing the objects of interest and additional GIS-data together in an integrated semantic model is essential to get an overview of the numerous relations between the different objects and how to exploit the prior knowledge. The strategy is derived from the mo...
