Exemplary Scenario of Rural Disaster Evaluation System with GRID

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

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

Analysis of Earth Dam Safety in Grid

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

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

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

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

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

Upper stream

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)

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

Resource investigation in the expected flooding area Expected Damage Investigation Resource investigation in the expected flooding area
