Constructed wetlands have recently started to be applied as the most important type of nature-based solution against the effects of climate change. This study investigates the determination of the most suitable site determination criteria for the application of this important nature-based solution tool by multiple decision-making methods. For this purpose, first of all, the literature was reviewed and the ten most important criteria for constructed wastelands were determined. Then, fieldwork was carried out according to these determined criteria, and a location was determined in the field according to each criterion. The global positioning system device is used to mark 10 locations that have been determined as waypoints for 10 criteria. The determined waypoints were then scored using the relevant criteria, and the best location was determined using the Multiple Attribute Utility Theory methods. Waypoint 1 received the highest score, 8.4, according to the results. Later, waypoint 7 received a score of 6.2, and waypoint 9 received a score of 5.7.
