Therefore, while investigating this issue, the current research has studied the area of ​​Sefidroud Manjil Dam as an area that can be prosperous and increase tourists by investing in it. Therefore, the novelty of the present study lies in the fact that to discover the relationship between natural aesthetics and the development of coastal tourism, while studying a large set of previous studies, the researcher has re-edited the influencing variables based on the purpose of this study. Therefore, the main goal of the current research is to investigate the role or effect of the aesthetic components of the natural landscape around the dams in the development of coastal tourism.
Methodology
The current research is in the category of applied research in terms of its purpose, and it is descriptive-analytical in terms of the nature and method of doing the work. To collect information, two library and field methods were used, which were used to examine the theoretical framework of the documentary and library method (books, theses, research, and articles) and to examine the aesthetic factors of the natural landscape around Sefidroud Dam in the direction of tourism development from studies Field and questionnaire tools have been used.

Findings and discussion
In this research, according to the calculation of GOF based on the outputs of SmartPLS software, which showed a value of 0/641, it can be said that the model has a strong fit. Therefore, in the continuation of the analysis, the researcher is allowed to investigate and test his research questions. Therefore, the research hypothesis was confirmed at 99% confidence level and zero significance level. In such a way that there is a significant relationship between environmental aesthetic quality factors as an independent variable and tourist development and attraction as a dependent variable. Also, the obtained path coefficient is equal to 0/881, which indicates a very strong effect coefficient between them. So, it can be confidently acknowledged that the variable of aesthetic quality in all the investigated dimensions can have a strong and positive effect on the promotion of tourism.
