Sponge City Based on Blue – Green Urbanism

Abstract

Blue-Green Infrastructure systems are essential and valuable solutions for urban and rural areas which are facing climate change problem. As climate change negatively affects vegetation systems, water systems, and life cycles, blue-green infrastructure solutions enhance the urban and rural landscape. The system combines the green and water networks and also manages stormwater. BGI develops a variety of urban ecological, economic, social functions, and also urban sustainability and liveability. In addition to these, the systems decrease the need of grey infrastructure and the negative impacts on urban ecology. BGI plays a specific role on development of stream and coastal systems, and also urban green areas. The system emphasizes the protection of hydrologic system and hydrodynamic processes, accordingly, water management systems which consist of rain gardens, green roofs, vertical greening systems, and permeable pavements are used. In the scope of the study, creation of Sponge City with Blue-Green Infrastructure systems and the construction processes are scrutinized. In connection with the idea, sponge city design tools are described.
