Abstract Intensification of extreme rainfall-runo events in arid and semi-arid regions because climate change induce the water erosion that contributes considerably to loss vegetal layers soils reduce storage capacity dams by silting transported sediments from watershed impoundment. This paper aims at proposing means for protecting Mghila dam against identification delimitation vulnerable areas...

statement of problem: one of the factors in dental erosion is consumption of acidic soft drinks. although the effects of various additives to acidic soft drinks for the prevention of tooth erosion have been assessed, little data have been published on the possibility of preventing the erosion through soft drinks containing calcium-carbonate nanoparticles.  objectives: to examine the erosive fac...

in this work, the effect of erosion on corrosion behavior of coal tar epoxy coating was evaluated usingelectrochemical impedance spectroscopy (eis) measurements. the surface morphology of the coatingwas examined by scanning electron microscope (sem) after 10, 20, 30, 45 and 60 min of erosion processat an impact angle of 90º. after 10 min of erosion process, the nyquist plots showed just a singl...

Coastal defences have long been employed to halt or slow coastal erosion, and their impact on local sediment flux and ecology has been studied in detail through field research and numerical simulation. The nonlocal impact of a modified sediment flux regime on mesoscale erosion and accretion has received less attention. Morphological changes at this scale due to defending structures can be diffi...

The Three Gorges Reservoir Area is one of the most severe soil erosion in China. Serious erosion has degraded the soil productivity, deteriorated the ecological environment, and influenced the service life of Three Gorges Reservoir. The natural and social-economic factors which influence the soil erosion in Three Gorges Reservoir Area include topography, geological situation, vegetation, rainfa...
