Soil erosion continues to be a threat to agricultural productivity worldwide, with soil losses in the United States exceeding 3 billion tons annually. Wind and water erosion have caused dramatic declines in soil productivity. Erosion protection and associated conservation of nutrients, organic matter, soil water holding capacity and biota are significant concerns. Pimentel et al. (1995) estimat...

Representation of surface roughness effects on aeolian sediment transport is a key source of uncertainty in wind erosion models. Drag partitioning schemes are used to account for roughness by scaling the soil entrainment threshold by the ratio of shear stress on roughness elements to that on the vegetated land surface. This approach does not explicitly account for the effects of roughness confi...

UCHIYAMA, Y., 2007. Hydrodynamics and associated morphological variations on an estuarine intertidal sand flat. Journal of Coastal Research, 23(4), 1015–1027. West Palm Beach (Florida), ISSN 0749-0208. Hydrodynamics, sediment suspension, and morphological response on an estuarine intertidal sand flat in Tokyo Bay, Japan, are examined through a field experiment performed for 16 days in winter 20...

Inner Mongolia is located in the north of China, where the development of wind power industry is outstanding. Because of the surrounding environment’s destruction by frequent sandstorm phenomena in recent years, wind fan blades are severely damaged. The purpose of this paper is to use PLC and touch screen to realize quantitative content of sediment erosion wear in accurate control. The whole te...
