abstract = "Mapping of flooded areas has been widely explored due to the
usefulness of this information to support emergencies. The land
use planning and disaster prevention involves the concept of
susceptibility to flooding which can be understood as the set of
natural conditions that predispose a region to be flooded, and can
be observed before the occurrence of a disaster. The delineation
of the floodplain observing the topography contributes to the
zoning of susceptible to flooding areas and is an interesting
complement to risk management. In this paper we have identified a
flooded area that was mapped using OLI images provided by Landsat
8 satellite, through the spectral index MNDWI. Simultaneously was
delineated floodplain from topographic height obtained from the
digital elevation model (DEM) of TOPODATA database. Different
cutting heights of topographic height was define (2m, 3m, 4m and
5m) generating a raster map for each section and the threshold
that defines the best plain was estimated by the accuracy of each
of the maps extracted from the topographic height and control map
corresponding to the flooded area. The estimates were made from
1000 random samples using contingency table showing that the best
threshold for establishing the floodplain is 3m with the following
parameters: CSI: 0.518, Phi coefficient: 0.531 and Kappa: 0.516.
We conclude that although the flooded area may underestimate the
area of the plain, is a good indicator for determining the cutoff
threshold of the floodplain which can be used for the management
of risk in a given territory.",
