Abstract: Sinkholes formation hazards in environment, case study: Sinkholes and Hazard in Hamadan plain and the Lar valley of Iran. The Sinkholes or Dollins are special form of karst geomorphology that is result of the chemical erosion of the groundwater on the carbonate rocks. The Sinkholes formation causes many problems in urban area and other region. The case study of this research is Hamadan plain and the Lar valley sinkholes. The research methodology contains review of geology, structural geology, hydrogeological conditions, study of sinkholes situation, and their characteristics. The most important characteristics of sinkholes studied in this effect on their formation and its occurred or probable hazard. There are 39 sinkholes in different size in Hamadan plain, northwest of Iran and 9 sinkholes in Lar valley north of Iran. The results of the research shows that the sinkholes are formed in carbonate bed rocks and these rocks are covered by alluvial in Hamadan plain and Lake Sediment in the Lar valley. Major hazards of sinkholes in Hamadan plain and Lar valley are farmland and irrigation system damage, groundwater pump stations damages, risk in electrical power generators; water well mud increasing, water well collapse, villages damage risk and uncontrollable discharge of dam reservoir. Keywords: sinkholes formation, hazards. |
