Abstract

Flood disaster is a major issues due to its frequently events on several areas in Indonesia.
Delineation of inundated area caused by flood is needed to support disaster emergency response. The
objective of this research was to identify inundated areas using NDWI methos from Landsat
TM/ETM+ data on lowland regions of Java island. A pair of the data (before and during the flood)
were in each observation areas. Observation areas were selected in several location of lowland regions
of Java island where great event of flood occurred during the last decades. The thresholds values of
NDWI change were used to separate the flood and non flood areas. The results showed that the extent
of inundated area caused by flood on lowland regions can be identifyed and separated based on NDWI
variables extracted from Landsat TM/ETM+.
