Many saline lakes throughout the world are shrinking due to overexploitation of water in their drainage basins. Among them two world’s largest lakes, U.S.A.’s Great Salt Lake, and Iran’s Lake Urmia. Here we provide a comparative analysis desiccation these that provides insights on management decisions may help save relevant lake worldwide. Urmia were once remarkably similar size, depth, salinit...
Compared with common dust storms, saline dust storms transport high concentrations of fine-grain saline and alkaline material. The saline dust storm differs from common dust storm, especially considering the sources of the suspended particulate matter (PM), chemical composition, grain size, and circulation processes. Atmospheric particulate matters (TSP, PM10, PM2.5, and PM1) and their water-so...
Urmia Lake has been designated as an international park by the United Nations. The lake occupies a 5700 km2 depression in northwestern Iran. Thirteen permanent rivers flow into the lake. Water level in the lake has been decreased 3.5 m in the last decade due to a shortage of precipitation and progressively dry climate. Geologically the lake basin is considered to be a graben of tectonic origin....
Human settlements as local -spatial systems are subject to continuous dynamism and transformation. In the meantime, rural settlements including; in Iran, as the most important establishment of population and activity, are exposed to the deepest environmental, ecological, social, economic and cultural changes. It is evident that in these developments, a variety of different and different forms o...
Declining water level of Lake Urmia is one of the environmental crises that has affected the adaptation capacity of the villagers around it. As it has incurred great costs in economic, social and environmental dimensions for the rural residents around it. Therefore, the purpose of this study is to study the factors and forces affecting the adaptation capacity of rural settlements in the face of...
this research summarizes the data on benthic macro invertebrates collected from 25 points in the urmia lake wetlands during november 2008 to february 2009. the purpose of the study was to assess the effects of elevated salinity and nutrient (nitrogen and phosphorus) levels on macro invertebrate abundance and composition. a total of 32 taxa were collected, and the common taxa, including chironom...
