Element Content in Volcano Ash, Soil and River Sediments of the Watershed in the Volcanic Area of South Iceland and Assessment of Their Mobility Potential

In this work, we present the results of element content in river sediments and soil Rangárvellir southern Iceland as well volcano ash from Eyjafjallajökull eruption 2010. Severe natural catastrophes have devastating impact on environment. We selected area located vicinity Mt Hekla, Iceland’s most active volcano, for our study. This study site is ideal to investigate wind water erosion sediment transport processes two main glaciers rivers: Eystri-Rangá Ytri-Rangá Hroarslækur River. Sediments these rivers consist materials, lava. order assess dynamics, collected sediment, volcanic ash. The fractioning elements was carried out using sequential extractions. distribution Si indicates that originate same geochemical basis. Li partly B exist first phase but not mobile phases soils. ash, P found it did sediments. These suggest different chemical fingerprints surrounding soil.
