The construction of the dam and related projects have always been accompanied by positive and negative effects. These effects affect the physical, biological, cultural and economic-social environments. The main purpose of the research is to investigate and evaluate the social and cultural consequences of the Sardasht dam construction in the western region of the country. The research method of the current research is qualitative method and the research method of this article is an exploratory approach with emphasis on foundational data theory. The findings of the research, which is the result of a field study and interviews with local people and regional officials, show that people pay attention to the negative effects of dam construction and managers pay attention to the positive effects of dam construction, and both groups of people and managers consider the development of tourism and the expansion of business and employment as social effects. And they know the culture of dam building in the region.

The life and development of human societies requires energy production and consumption, the need to pay attention to the environment and the fatalities of fossil fuels for energy production has focused on the use of energy from renewable energy sources. New energies are important because they are a good alternative to fossil fuels. Fossil fuels cause environmental pollution and air pollution. Geothermal plants, on the other hand, also have environmental impacts on vegetation around the power plants. In this research, various vegetation indices have been used to investigate the potential damaging effects of Meshkinshahr geothermal power plant on vegetation around the site of the power plant. Investigations using Landsat 7 and 8 satellite images and ETM + and OLI sensors from the target area and extracting the SAVI index in two periods of 2000 and 2017 showed that the vegetation index of the areas around the site of the power plant Geothermal has dropped to 6.68 square kilometers. Residential, soil and water areas also increased 53.69, 14.26 and 0/255% respectively. Comparison of two classified images showed that the lagoon class in 2000 had an area equal to 11.18 km2, down from 95.91 km2 in 2017. In addition, the class of residential areas in 2000 has an area of 95.74 km2, in 2017, it is up to 120.41 km2, the soil class ranges from 219.59 km2 to 405.82 km2 and the water class ranges from 0.43 to 0.69 km2 has risen.The life and development of human societies requires energy production and consumption, the need to pay attention to the environment and the fatalities of fossil fuels for energy production has focused on the use of energy from renewable energy sources.

Power plants are one of the most important sources of heat islands. Increasing energy consumption, change of thermal factors and creation of microclimates, affect the conditions of people's presence in open spaces and the use of these spaces greatly depends on a person's thermal perception of the environment. Therefore, the importance that is felt in establishing comfort in open spaces of industrial and power plant environments, is for a longer and better quality presence of employees in this category of spaces. The study of the thermal performance of open spaces in different applications has been evaluated in relation to their micro-climatic behavior, but such a study is not available with the aim of correct and principled design of outdoor power plants. Therefore, the present study has tried to study and recognize the structural features of the outdoor space of Neishabour Combined Cycle Power Plant, using ENVI-met 4 software to simulate and measure the microclimate conditions of the plant and changes in climatic parameters including air temperature, Evaluate relative humidity, wind speed, average radiant temperature and PET climate index on the hottest (July 23) and coldest days (January 20). The results show that the thermal conditions of the power plant are out of the range of thermal comfort in summer and winter and during office hours; Based on the proposed designs, it was found that by reducing the density of vegetation in the direction of the prevailing wind, the humidity in the center of the site can be increased and by planting deciduous trees and with a cross pattern in the direction of cold winter winds, comfort conditions Increase in the center of the site and the busy route of employees.
