  1. Applications to Rural e-Science Jeong-Jae Lee Seoul National University

  2. Exemplary Scenario of Rural Disaster Evaluation Systemwith GRID

  3. Disaster Management of Rural Area; Flooding of arable lands • Prediction and evaluation of the extent of damage by flooding of arable lands • Using nomographs for damage evaluation of low-land rices • Needs precise measurements and prediction of geographic and meteorological locality • Elementary simulation models to constitute complex agricultural system should be constructed

  4. Disaster Management of Rural Area;Breaking of reservoirs • Extend the management program for large dams to agricultural reservoir embankments • Rural areas’ conditions are changed with development • Needs design specification and risk management regulations for all dams • Elementary simulation models to constitute Action Program for rural disaster management

  5. Analysis of Earth Dam Safety in Grid

  6. Analysis of Dam Break • Analytic Model for Rainfall-Runoff Relationship based on watershed • Runoff and Routing Simulation • 1-D stationary flow • Hydraulic analysis for the unsteady flow • Sediment movement

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

  8. Application of GIS for Data Acquisition (sample area) Terrain Processing Watershed polygon Flow direction Depressionless DEM

  9. Direct Runoff subbasin Baseflow Method Loss Rate Application of Hydrologic Model (sample area) Basin Processing Component of subbasin Subwatershed boundary Merged watershed

  10. 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 GIS data for River Routing(sample area) TIN Contour Stream

  11. Upper stream

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

  13. Damage Assessment • Expected Failure Cost caused by Flood • = ∑ Probability of Failure x Unit cost of Typical Resource (I) x Amount of Resource(I)

  14. Expected Damage Investigation • Resource investigation in the expected flooding area

  15. Middleware for Grid and e-Science

  16. Objective Software Module

  17. Integration of Objective Software Modules

  18. JAZZ; The User Interface for Software Platform

  19. Knowledge Transfer Through Software Platform

  20. Integration of Simulation Models • Simulation Models are essential in science and engineering fields • Building Simulation Models of Large System is not feasible • Integration of Independently Developed Simulation Model is an Alternative Method

  21. Unidirectional Information Propagation Scheme

  22. Generic System Models Simulator (GSMS) Environment

  23. JAZZ & GASS for Grid • JAZZ is capable of integrating Database services using appropriate software modules • GASS is capable of integrating Database services with computing services using appropriate simulation models
