Water is one of the most important resources on earth. However, due to the drought crisis in Iran and the need to save water and study the determinants, this study was conducted to predict environmental behavior by relying on water consumption behavior based on environmental awareness, attitude, and concern. The research is a survey in which ۸۶۵ citizens of Kermanshah City answered the research questionnaires by cluster sampling. The data was analyzed by statistical methods using SPSS software. The results showed that the variables of environmental knowledge (۳۱ %), environmental concern (۳۴ %), and environmental attitude (۵۴ %) have the ability to predict the environmental behavior of water consumption. Therefore, people with higher knowledge, concerns and environmental attitudes are more diligent in saving water. According to the results of this study, explaining environmental behavior using three variables of environmental knowledge, environmental attitude, and environmental concern can be suggested to implementers and policymakers for use in developing interventions and educational campaigns and raising people's environmental awareness and knowledge. Also, these results can increase the paying attention to their environmental attitudes toward water consumption, can demonstrate that water conservation is realistic and practicable for people, and can convince them that they can engage in conservation-related behaviors. These results have the potential to raise people's awareness of their environmental attitudes about water consumption, illustrate that water conservation is feasible and achievable for them, and persuade them that they can engage in conservation-related actions.
