We organized precipitation data ( Incheon; 2004 ~ 2007) and summarized rainfall events.
We picked up the heaviest amount rainfall event and the highest rainfall intensity event.

Project studyAnalysis of flood damage reduction by green area increase
2010 team Purple2010 team Purple
Analysis of flood damage reduction by green area increase
Green areas allows: ◦ water drainage : runoff decrease
Depression shape: additional water storage during rainfall◦ Relieves sewer system discharge◦ Slows down the water flow, narrows flood peak
Increases well-being and quality of life of the city's inhabitants, environmental friendly
Project subject
2010 team Purple2010 team Purple
Determine the location of these green areas◦ Nature of soil and landuse?◦ Size?◦ Dimensions?◦ Number?
Use of ArcGIS to determine potential locations
Run the calibrated model again with new catchment characteristics and subsequently choose best solution...
Targets, next steps
