Environmental management of water resources and environmental issues with a view to the Urmia Lake
Abstract:
In terms of water quantity and quality is the most important part of an ecosystem. Reduced both the quantity and quality of water in a large negative impact on ecosystems and biodiversity threaten leaving Natural food sources and effects on organisms and causes irreparable damage, Knowledge and information about water rights and the application of specific rules to regulate the management macro environment seems essential. Therefore, based on this study on the lake among the largest watershed of the country is carried out in terms of location geographically in northwestern Iran between East Azerbaijan and West Azerbaijan longitude 44 degrees 14 minutes to 47 degrees 53 minutes east and 35 degrees 40 minutes north latitude to 38 degrees and 30 minutes is locatedThe main reasons for studies on slow dry lake-level changes in temperature and precipitation in the region of 79-83 were studiedAnd consequently the rate of temperature change is not so drastic drop in water level can cause dry lakes and rainfall of 79-83 years of upward growthDuring the same period, but the water level of the lake has suffered a significant drop. Check water level fluctuations indicates that in 1346 the lowest level to the height of 1273/86 (m) free water level is reached, If the water level over the past thirteen years to1272/00 (m) about 6/20 mm reduced. In the present study, we believe that the gradual construction of 72 dams catchment basins with the average rate 4/5 billion cubic meters, the lake provides a huge change. Other factors, such as dam construction, the double-pass martyr station in front of the natural cycle of water under stirring the natural order of living plant material suspended in the water cycle, the water creates many changes in the ecosystem. The indiscriminate digging of the wells during the past seventeen years (91 74) of approximately 650 thousand to 336 thousand Ring has increased among the factors that makes it believe that responsible decisions in the coming years factors inland lake with a rejectUndoubtedly, completely separate the lake into northern and southern even completely dry lake will follow.
