INTRODUCTION - TOPIC

Study area: Incheon Gyo Watershed

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

18

DELIMITATION OF THE AREA

Clip tool: catchment file with roads, buildings and contour cut the features following the shape of the

catchment

+CLIP

19

CREATION OF A DEM

First step: to create a TIN (= Triangulated Irregular Network)

Tool : 3D analyst

20

CREATION OF A DEM

Creation of a DEM for each layer (contour, buildings and roads)

DEM = Digital Elevation Model

Tool : feature to raster

21

FROM DEM TO MESH FILE

Merge the 3 rasters in one

Convert the final raster in Ascii to use in MOUSE as a mesh

22

MOUSE

23

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

CONCLUSION

Next few days expectations:

Getting to know each others Put our informations and work in common Define the next steps in our work Define the new sub-team and people

responsabilities Completely finish the model and run all the

simulations

THANK YOU FOR YOUR ATTENTION!
