Özet

The water reserve in the world, which is vital for life, has been gradually decreasing recently and it has been rapidly depleting despite it is known to be one of the renewable resources on earth. Considering the global water reserves, it became imperative to implement measures to protect the anticipated water reserves. The fact that the amount of quality water per capita decreases every day in the world and the increasing competition in water management could be considered among the indicators of the above-mentioned case. In recent years, as the effects of this adversity became increasingly more evident, several sustainable methods were adopted all over the world such as rain gardens and rain water storage facilities. These sustainable techniques could be observed in many areas, especially in urban centers. In this study, the area which has the highest rain water collection potential at the Karadeniz Technical University Kanuni Campus was selected as the study area. Precipitation per square meter and surface runoff volume were identified based on the GIS (Geographic Information System) data, annual water collection volume was calculated, and information on economic and ecological recycling of the water was provided. In conclusion, the precipitation data for 11 years were compared, and it was calculated that the average annual precipitation was 64.06 kg/m(2) and annual surface runoff water was 552.77 m(3). Based on the surface runoff water volume in the months when no irrigation is conducted, a reservoir was designed under the main road in the campus and water recycling recommendations were developed.
