Investigation of Dam Construction Effects without Environmental Assessment (Case Study: Urmia Lake) Original Article, C32 Majediasl M, Sangi A. Journal. Civil Eng. Urban. 3(4):201-206. 2013 ABSTRACT:Feedbacks on numerous harmful problems in the environment have caused appearance of some human society’s sensitivity about the range of human’s non-limited activities in the environment which are done without considering environmental limitations during the economic development process in the recent decades. If environmental problems, along with technical and economic justifications are not considered, activities related to the water resources development program will result in irreparable and undesirable consequences. Drying up of the lake due to irregular exploitation of catchment basin water resources and construction of several dams on the branches of its rivers without environmental assessments have led to increase in the region’s temperature, appearance of sand and salt storms, destruction of potential agricultural land, flooding, change in cultivation pattern, hence jeopardizing the life of region’s people. Because of these, Natural ecosystems existing around the lake have been changed remarkably, and animates’ habitat in the lake is going to be destroyed. So, it is necessary to carry out an accurate evaluation before implementing water resources projects during the investigation of economic and technical justifications, so that any exploitation of nature can be done in the framework of the capabilities and potentials of natural environment. In this paper, we present some approaches to fight against undesirable consequences of dam construction, investigating environmental changes in Urmi a Lake.
