Environmental parameters affected by the dams were identified, field and laboratory investigations were conducted, and their impacts were assessed. Detrimental impacts were found to have resulted from: ? Siltation of lakes and loss of routine silt deposits on agricultural lands ? Changes in permeability of soil. ? Changes in quality of water. ? Public health concerns related to transmission of water born diseases. ? Destruction of irrigation galleries. ? Socio-econornic effects resulting from migration of local residents to nearby cities. Systematic guidelines consisting of five major phases and eleven steps have been developed for the purpose of Environmental Impact Studies to fit the local needs for planning all public water projects, in general and dam projects in particular, and to provide mitigation measures to alleviate the impacts of such projects. In view of the grave significance of the effects as mentioned above, the research has recommended careful social, economic and environmental evaluation of all proposed dam projects prior to their construction as a long term solution, and to revise operation and maintenance programs of existing projects as a short term solution to mitigate identified impacts.  ISSN : 1319-1047  Journal Name : Engineering Sciences Journal  Volume : 12  Issue Number : 2  Publishing Year : 1420 AH 2000 AD  Article Type : Article  Added Date : Thursday, February 4, 2010  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email عبدالله مصطفى مهرجي MOHORJY, ABDULLAH M.
