1. Rural e-Science what we may need to survive ourselves! Jeong-Jae Lee & Byong-Lyol Lee Seoul Nat’l Univ. / NCAM

4. Analysis of Earth Dam Safety in Grid

5. Routing Flood Wave Normal water level Flooded water level Embank of river Section of AA Routing Flood (X) Distance from the dam Elevation Depth of Flood A A

6. GIS data for River Routing (sample area) TINContourStream Generate TIN using NGIS data  Topographic data such as streams, banks, flow path centerlines,  Cross section and cut lines such as profile that can be surveyed

7. Upper stream

8. Collapsed embankment caused by overtopping: It's caused by insufficient spill-way section (Ui- Seong KyungBuk, Korea 2000) Collapsed embankment caused by piping underneath the chute: It's started from the toe of chute (An-Dong KyungBuk, Korea 2000) Failure of Earth dam
