Orde r Date [day, month, year] Precipitation [mm/event] 1 15 th July 2006~19 th July th July 2006~30 th July th July 2006~13 th July th July 2004~17 th July th July 2005~28 th July  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. Hydrology Study(1) Orde r Date [day, month, year] Max Intensity [mm/event] 1 27 th July 2005~28 th July th July 2006~30 th July th July 2006~13 th July th Sep 2005~13 th Sep th June 2005~27 th June Table1 : Top5 events of the biggest amount per 1 event. Table2 : Top5 events of the highest rainfall intensity.

2010 team Purple  We made both the heaviest rainfall event and the highest rainfall intensity event hyetographs. Hydrology Study(1)

2010 team Purple  1 st step: Intensity‐Duration‐Frequency Estimates Design flows established from: Rainfall intensities for storms of particular duration and return period.

2010 team Purple  2nd step: Develop design hyetograph from IDF curve - We made a 6h storm -by using the alternative block method.  Input rainfall data into Mouse boundary conditions. Hydrology Study(2)

2010 team Purple MIKE ZERO DEM MIKE 21 Simulating the surface flow Simulating the sewer network flow MOUSE MIKE FLOOD Coupling MOUSE with MIKE21 Results

2010 team Purple DEM: Boundaries Conditions ： Simulation period MIKE 21 Simulating the surface flow ・ buildings ・ roads ・ manholes ・ … ・ sea level ・ pump operations ・ … Rainfall

2010 team Purple MOUSE Sewer Network Boundaries conditions Simulation Period Simulation of the Sewer Network flow

2010 team Purple Analysis of flood damage reduction by green area increase

2010 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

2010 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...
