3. I NTRODUCTION - T OPIC Study area: Incheon Gyo Watershed 3

4. I NTRODUCTION - T OPIC The city of Incheon in South Korea had a devastating flood in 1997 on the Incheon Gyo located near the Yellow Sea. This area is influenced by tide level, inundations occur. Incheon Gyo has a gentle slope and lowland, inundation often occurs by rainfall. Topic: we will analyze reduction of water level in this area by using ArcGIS and MOUSE. 4

15. W ORK DISTRIBUTION Create and administrate the team website: Guillaume QUARO and Maxence CHATELUS Write the weekly reports of advancement: Hyeongjun HAN, Soyoung LEE and Young-bin KWON Make DEM by ArcGIS: Guillaume QUARO and Maxence CHATELUS Hydrological studies: Young-bin KWON Analyze through MOUSE: Hyeongjun HAN, Soyoung LEE and Young-bin KWON 15

16. A RC GIS 16

17. W HAT IS GIS? GIS = Geographic Information System Why are we using these GIS data?  To have a delimitation of the area, with the topography and the buildings, the roads…  To create a mesh for MOUSE software Which software are we using?  ArcGIS (ArcMap) made by ESRI 17

18. D ELIMITATION OF THE AREA Clip tool: catchment file with roads, buildings and contour  cut the features following the shape of the catchment + CLIP 18

19. C REATION OF A DEM First step: to create a TIN (= Triangulated Irregular Network) Tool : 3D analyst 19

20. C REATION OF A DEM Creation of a DEM for each layer (contour, buildings and roads) DEM = Digital Elevation Model Tool : feature to raster 20

21. F ROM DEM TO MESH FILE Merge the 3 rasters in one Convert the final raster in Ascii to use in MOUSE as a mesh 21

22. MOUSE 22

23. W HAT IS MOUSE? MOUSE is a program which provides sewage pipe, open channel, surface runoff etc, flow simulation as well as hydraulic analysis. Why are we using MOUSE program?  Analyze of reduction of water level in sewer pipe.  Risk analysis of flood damage What kind of software are we supposed to use?  MOUSE And MIKE View 23

24. S EWAGE PIPE NET BASED ON 1997’ S DATA 24

26. C ONDITION Decide Of Critical Rainfall Duration 26 - 5min : 166.58 mm/hr - 10min : 152.51 mm/hr - 15min : 142.07 mm/hr - 20min : 133.72 mm/hr - 30min : 120.79 mm/hr - 40min : 110.00 mm/hr - 50min : 103.19 mm/hr - 60min : 96.74 mm/hr <Probable Rainfall Intensity Formula Considering the Pattern Change of Maximum Rainfall at Incheon City>
