Abstract :The rapid population growth in the world and the adverse effects of climate change, has caused a severe increase in water demand used in sectors such as agriculture, industry, and domestic usage. The fact that the water resources in the world are stable and their availability is limited, the importance of water resources, efficient use of water, and the use of technologies related to alternative water resources have become important. This study aimed to investigate the usage potential of rainwater to be collected from the roofs of the building in irrigation of green areas in Mersin University - Çiftlikköy campus. For this purpose, first, whether the roofs inside the campus can collect rainwater will be revealed with unmanned aerial vehicles. Then, appropriate roof areas where rainwater will be collected will be calculated using the object-based classification method. The rainwater amounts to be collected from each building will be calculated using the monthly precipitation data obtained from the Provincial Directorate of State Meteorology Affairs. In addition, by calculating the number of green areas on the campus and the need for rainwater, it was determined how much rainwater to be collected meets the water need according to different irrigation periods.
