| Abstract |
This study draws technical elements, application areas, and design methods of green infrastructure for the restoration of urban hydrological cycle by analyzing 11 green infrastructure planning and design practices which are included urban wetland park, stormwater park, eco-stream, residential development, green buildings, and green streets. The result of the analysis is as follows. First, green infrastructure as a multi-dimensional system is comprised of various landscape elements such as rain gardens, stormwater planters, curb extensions, green roofs, constructed wetlands, bio-swales, permeable pavement, rain barrels and so on. These landscape elements can be applied to various land-use types such as buildings, rooftops, parking lots, walkways, roads, green spaces, and waterfronts. Secondly, green infrastructure as an ecological system can process stormwater runoff in natural ways. Green infrastructure utilize not only hard engineering technologies but also biological process which is comprised of evapotranspiration, retention, filtration, and infiltration. Thirdly, green infrastructure as an interconnected system can reduce more effectively stormwater runoff when green infrastructure elements are interconnected although each of them as an independent system can process stormwater runoff in natural ways. |
