Setting Inflow and Output
Parameters in BASIN
The goal is to estimate the damage (cost)
caused by a flooding in an developed area.
Calculation is based on the FLO-2D results
(maximum depths) and a cost assigned to each
building or area for a number of water depths
FLO-2D input (*.DAT) and output (*.OUT) files.
A polygon shape file (ESRI) containing an index for
each polygon. Each polygon represents a building,
house or vulnerable area (houses.shp).
A table file (*.TBL) containing information on the
damage (cost ) as function of flood depth for each
building type in the polygon shape file
The damage table file has this format:
Cost for each building
code and each depth
Procedure is as follows:
Read FLO-2D results
Display the FLO-2D predicted maximum flood depth
Import the building polygon shape file
(DamageCode_08.tbl) using the Import Shape file Command
in the File menu.
Select Estimate Flood Damage Command in the Tools menu.
Import the damage table file *.TBL
Click on Compute Damage button to calculate damage
estimate for each building
Edit damage layer to display values
