INTRODUCTION - TOPIC
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, inunda-tions 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.

WHAT 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
![Page 18: B LUE T EAM B LUE T EAM - W EB WORK AND TEAM PRESENTATION 2010 1](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d2e5503460f94a05220/html5/thumbnails/18.jpg)

DELIMITATION OF THE AREA
Clip tool: catchment file with roads, buildings and contour cut the features following the shape of the
catchment
+CLIP

CREATION OF A DEM
First step: to create a TIN (= Triangulated Irregular Network)
Tool : 3D analyst
![Page 20: B LUE T EAM B LUE T EAM - W EB WORK AND TEAM PRESENTATION 2010 1](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d2e5503460f94a05220/html5/thumbnails/20.jpg)
20
CREATION OF A DEM
Creation of a DEM for each layer (contour, buildings and roads)
DEM = Digital Elevation Model
Tool : feature to raster
![Page 21: B LUE T EAM B LUE T EAM - W EB WORK AND TEAM PRESENTATION 2010 1](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d2e5503460f94a05220/html5/thumbnails/21.jpg)

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

WHAT 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
