Abstract :
Introduction: The water crisis in the country, as well as the optimal use of water resources, the distribution and transfer of water through small dams in the country have been taken into account, which has led to the control of the flow regime during floods and water supply due to less negative effects. Drinking and farming work better. The purpose of the research is to evaluate the environment of successive dams in the river bed and also its effects on environmental factors in the region. Materials and Methods: In this research, it tried to investigate the environmental evaluation of successive small dams in the river course of Karin region of Fars province and to determine the positive and negative points of the construction of successive dams using Leopold's matrix. Three physical, biological, economic, social and cultural states were studied and evaluated in two phases of construction and operation with option 1 (not doing the project) and option 2 (doing the project). Results and Discussion: The assessment of environmental effects in the biological part of option 1 shows that the total score of the construction and operation phase has obtained a score of -212, which has the greatest negative impact on the factors of animal species mortality, reduction of biological food and growth and breeding of aquatic animals, and destruction. Vegetation can be seen in option 2 (execution of the project) on biological activities. It shows that the sum of points for the construction and operation phase has scored +295, which is the most effective factors of animal species migration, impact on the food chain and growth and development. Vegetation and aquatic cover. Conclusion: A general review of all environmental factors, although the option of not implementing the project has a negative score of 138, but not doing the project and leaving the area to itself is actually not using natural resources and not moving towards sustainable development. In the total scores of the entire economic, social and cultural environment, it was concluded that with the effect score of +2107, this action can have an effect on the economic, social and cultural prosperity of the region in the future, as well as the construction of successive dams, in addition to the change in the region's ecosystem, will cause Economic prosperity and water quality and quantity.
