5.0 RESULTS AND DISCUSSIONS
Flood extents derived from the satellite image satisfactorily
matches that of the HEC-RAS model. The area near stream is
dry according to the flood extent derived from satellite images.
This can be expected as the images were taken on receding limb
of the flood as flood peak had been occurred around two days
before the satellite image was taken. However, the results are
promising. The flood extents derived from the satellite image
and the HEC-RAS matches very well though the extent was less
in the satellite image.
