             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.",
