摘要

Salinity is one of the greatest long-term problems facing many parts of Azerbaijan, Iran. It is degrading and will continue to degrade our natural environment and our agricultural productivity. Dams sited on foundations and abutments containing soluble minerals have the potential to develop seepage and dissolution problems which require monitoring by water resource managers. The central reach of the Ajichay River, between Urmiah Lake and the Douz- Douzan area, is known for high salinity. These high levels of stream flow salinity not only reduce the economic uses of the water, but also limit the biodiversity of aquatic and riparian species along the Ajichay river. The causes of high salinity between Douz- Douzan and Urmiah Lake, especially "Ajichay reservoir dam," are saline water intrusion from both surface and subsurface sources, low runoff into the river, and evaporative concentration of the stream. The amount of salts entering this reach is estimated to be 250000 to 300000 tons/year.
