In this study, the hydrological-hydraulic model of the Tavukçu Stream Watershed in Istanbul is produced. Then, the green roof is integrated into the model produced. The results of the model are evaluated and the impacts of green roofs on the surface runoff on the watershed are investigated. First of all, the watershed area, slope, boundary, elevation map, landuse, soil type and stream routes of the Tavukçu Stream Watershed are modeled by using the Watershed Modeling System (WMS) computer program. Secondly, Environmental Protection Agency Storm Water Management Model (EPA SWMM) program is used to generate the hydrological-hydraulic model. Finally, 5%, 25% and 50% of the watershed area are defined as green roof. In the model, the surface flow rate at the outlet of the Tavukçu Stream Watershed is obtained as a result of precipitation. Then, the surface flow rate after green roof implementation in the model is obtained. By comparing these flow rates obtained from model, the effect of different rates of green roof applications on surface runoff is observed. In addition, cost analysis are made for green roof applications with various ratio.
