5 27th July 2005 ~ 28th July 2005 127.7

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.

Table1 : Top5 events of the biggest amount per 1 event.

Table2 : Top5 events of the highest rainfall intensity.


We made both the heaviest rainfall event and the highest rainfall intensity event hyetographs.

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.

Project studyAnalysis of flood damage reduction by green area increase


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


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


Thank you for your attention
