  9. HYDROASIA TEAM-RED • Adviser : Gye woon Choi • Nationality : Korea • Professor of National University of Incheon • Executive director of Incheon Regional Environmental Technology Development Center

  10. OBJECTIVES OF STUDY • Main purpose • Runoff analysis based on rainfall data and DEM • Mapping Flood Risk • Comparison with Real Flood • Comparison with results simulated with different parameters and model • To find out optimized Storm Performance

  11. OBJECTIVES OF STUDY • Making good experiences • Collaborating on a study with foreign students using the internet as a common working and communication platform • Sharing knowledge and skills • Experiencing the ‘Technological Culture’ for a sustainable water management

  12. UPLOADING THE PLATFORM • Production of Weekly Reports • Production of Documents and easy tutorials

  13. MOUSE Model Set up Validation MIKE21 Model Set up Validation Flow chart Overall frame work • Overall frame work MIKE FLOOD Set up PreparationGIS Coupling Rainfall Analysis Preprocessing for MOUSE Run Model Check the result and evaluation

  14. INTRODUCTION • Incheon city • Area : 1002.07㎢ • Population : 2,686,022 persons • Density of population : 2,680 persons/㎢ • Location : • A gateway to Northeast Asia with both international port and international airport in its hand • Incheon is located in the mid-west Korea peninsula abutting the Yellow Sea. • A city located 28km from the nation’s capital, Seoul, lies at 126° 37´ of east longitude and 37° 28´ of north latitude. • San Francisco, Washington, Madrid, and Teheran are found on the same latitude. `

  15. INTRODUCTION • Incheon-gyo Catchment • Area : 3,091.7 ha • Elevation : 5.4~24.0 m (EL+) • 33.1% of area is less than 7m (EL+) • Avg. of Slope : 0.01 % • Avg. of Rainfall : 1,702.3 mm/year • Landuse : Residence, Market, Industrial • and Green (Hill, Agriculture)

  16. PRE-PROCESSING WITH GIS • A GIS is a computer system capable of capturing, storing, analyzing, and displaying geographically referenced information • GIS can display the Earth in realistic, 3D perspective views & animations that convey information more effectively • The main purpose of GIS analysis is to study the topographical characteristics of the study area which is further used for flood modelling

  17. PRE-PROCESSING WITH GIS • Clipping map as catchment shape • Making Terrain map with interpolation

  18. PRE-PROCESSING WITH GIS • Making grid-Raster data set • Exporting data set as Ascii file

  19. PRE-PROCESSING WITH GIS (ArcScene) • 3D representation of building within catchment area

  20. PRE-PROCESSING WITH GIS (ArcScene) • 3D representation of road network within catchment area

  21. INTRODUCTION-MIKE FLOOD • MIKE FLOOD • Hydrodynamic Integrated model with 1D and 2D • The result of either 1D or 2D model can be transferred as input of another model • 1D Model • MOUSE : For Analyzing Urban Sewage • MIKE 11 : For Analyzing Open Channel Flow • 2D Model • MIKE 21 : For Analyzing surface complicated overflow

  22. INTRODUCTION-MIKE FLOOD Surface Runoff Overflow Sewage/Rainfall water Sewage/Rainfall water Re-inflow after flood Flow-capacity excess Rainfall Runoff

  23. URBAN DRAINAGE MODEL SETUP • Importing Network system data into MOUSE • Setting up Urban Drainage model with MOUSE • Validation

  24. URBAN DRAINAGE MODEL SETUP • Import Ascii data-set as bathymetry • Setting up Urban Bathymetry with MIKE21 • Validation

  25. MIKEFLOOD MODEL SETUP • Setting up MIKE Flood model • Coupling : Link MOUSE Manholes to MIKE21 • Preprocessing for MOUSE Model • Running Model • Check the results

  26. ANALYZING RESULTS Gajwa-WWTP Pump Station Flooded area Incheon gyo Juan st. Ganseok st. Catchment boundary Cityhall

  27. ANALYZING RESULTS • Comparing the Result (Modeled VS Reported)

  28. ANALYZING RESULTS • Result Video

  29. CONCLUSION • The Simulation has been built through web-collaboration of Team-Red • Model has been run successfully with good looking result • The advantage mapping with 2D surface runoff modeling could be found as following • The terrain characteristic can be considered • The lag due to the puddle, discontinuity can be considered • The magnification of result can be prevented with distribution of flooded water to another manhole • This study is expected to be continued as following further plan

  30. FURTHER PLAN • Applying Building layer map • Investigating the way to apply runoff coefficient • Applying RTC gate and pump • Discussion of 2D Runoff result • Discussion of Precipitation Intensity • Discussion of Solution • Comparison with results simulated with different parameters and model

  31. Lets take pride in being TEAM RED !!!
