  11. OBJECTIVES • The collaboration of the five universities, based on the use of the internet as a common working platform, aims to establish and share high quality teaching courses, and furthermore to strengthen links between students from the partner institutions • Flood analysis of Incheon Gyo catchment based on metrological data, tidal data, DEM …

  12. 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

  13. MOUSE SETUP • Import from the excel file “Imported data to Mouse.xls” to Mouse • Setting up Urban Drainage model with MOUSE • Validation

  14. Input Rainfall Data • Maximum rainfall • 28/7/2005 12AM ~ • 28/7/2005 4AM • (4 hrs)

  15. Flood Result

  16. IMPORT NETWORKS TO SOBEK • Import from the excel file “Imported data to Mouse.xls” to Mouse with modified node IDs. • From Mouse, export drainage networks system (nodes, pipes, cross sections, catchment) to SVK19 text file (the standard Scandinavian exchange format for sewer systems) • Modify the model coefficients, input rainfall and tidal data as downstream boundary condition

  17. INCHEON SEWER NETWORKS SYSTEM

  18. PRELIMINARY RESULTS

  19. WATER LEVEL AT NODES (MANHOLES)

  20. WATER LEVEL AT NODES (MANHOLES)

  21. DISCHARGE AT BRACHES (PIPES)

  22. DISCHARGE AT BRACHES (PIPES)

  23. WATER ON STREET AT NODES (MANHOLES) NODES NOT AT FLOOD AREA

  24. WATER ON STREET AT NODES (MANHOLES) NODES NOT AT FLOOD AREA

  25. WATER ON STREET AT NODES (MANHOLES) NODES AT FLOOD AREA

  26. WATER ON STREET AT NODES (MANHOLES) NODES AT FLOOD AREA

  27. SIDE VIEW OF SIMULATION RESULTS

  28. CONCLUTION • The models has been built through web-collaboration of Team-Green • Models has been set up and run successfully with reasonable results

  29. FUTURE PLAN • Discuss rainfall-runoff simulation results from Mouse, Sobek • Analyze the models with different model coefficients and boundary condition • Validate for different periods of high rainfall intensity using Mouse and Sobek • Compare the results from the two models • Suggest a solution to help prevent flood problems
