7.7. SOBEK Flood Analysis using data from “Real precipitation from SOBEK Flood Analysis using data from “Real precipitation from Incheon Rainfall Station.xls” and “Tidal data.xls”Incheon Rainfall Station.xls” and “Tidal data.xls”

Importing manhole and all necessary information to SOBEK

Rainfall data file was created to run the flood analysis

Tidal data file was created for boundary condition

Complexity…

Nodes with same IDs – Svk19 format, the Node IDs are limited to 7 characters only, thus, node ID’s name which exceeds 7 characters will be then taken out from the first

7 characters from that long name

Storage area in Manhole by default 100 m2. > 2600 nodes/manholes that need to be corrected to the actual manhole storage area.
