Metalliferous mining activities produce a large quantity of waste materials (such as tailings), which frequently contain excessive concentrations of heavy metals. These mining activities and waste materials have created heavy metal pollution problems through wind and water erosion. An integrated vetiver technique (IVT) for remediation of heavy metal contamination raised from mining activities i...

soil erosion is a major problem for developing countries with arid and semi-arid climate. these of erosion is possible than two ways of water and wind. in this paper, with using of two methods irifer and hierarchical models, the rate and intensity of of soil erosion is estimated shadegan catchment. for this purpose, by using various maps alike dem, rainfall, land use index, ndvi, geology estima...

Wind erosion and dust storms are main issues in arid and semi-arid regions. Application of soil stabilizer on unstable land might be an eff ective and sustainable strategy in arid and semi-arid countries to minimized harmful eff ects on environment and human health. Th e aim of this study was to assess the eff ect of using nanoclay for increasing soil stability, as a result of increasing in siz...

[1] Wave-generated shear stresses are the main mechanism responsible for sediment erosion on tidal flats and regulate both sediment concentrations in the water column and, together with tidal currents, sediment export to salt marshes and to the ocean. We present herein a simple method to estimate sediment erosion potential in shallow tidal basins caused by wind wave events. The method determine...

Soil analyses and measurements with the Portable In Situ Wind Erosion Laboratory (PI-SWERL) were conducted on 16 soil types in an area heavily affected by off-road vehicle (ORV) driving. Measurements were performed in ORV trails as well as on undisturbed terrain to investigate how ORV driving affects the vulnerability of a soil to emit PM10 (particles<10microm), during the driving as well as du...

Soybean-urease induced calcite precipitation (SICP) is an effective method for the improvement of sand, which forms a biocemented layer on desert sand surface to resist erosion by wind. Under this study, field tests were carried out determine how SICP approach may enhance resistance wind-induced and durability treatment in southeastern margin Tengger Desert, Ningxia Hui Autonomous Region, China...
