Land degradation, or desertification, is specific to arid, semi-arid, and dry sub-humid regions. The rate of thisphenomenon is high in developing countries such as Iran. This research investigated desertification and mapping ofdesertification in Abuzaydabad, near Kashan, Iran, with an emphasis on land criteria using an IMDPA model.Different studies have assessed land degradation or desertificat...

this study used quantifying factors affecting desertification based on the iranian model of desertification potentialassessment (imdpa) to assess the current status of desertification in bordekhun region, iran. bordekhun region has anarea of 214.11 km2 and is located near the city of daiyer in boushehr province. first, a working unit map of the regionwas selected as the basic map for evaluation...

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...

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...
