Abstract
The morphometric characterization of riverwatersheds is of great importance and is used to predict extremehydro-meteorological phenomena (floods). The aim of this workwas to morphometrically characterize the Lucite River subwatershedusing geotechnologies. Based on the Digital ElevationModel, using SRTM (Shuttle Radar Topography Mission) data,the following watershed morphometrics were determined:Drainage area, Watershed perimeter, Coefficient ofcompactness, Form factor, Circularity index, Declivity, Altitude,Maintenance coefficient, Drainage density, Hydrographicdensity, Torrential coefficient and Watershed order. Allprocedures were processed in ArcGIS 10.5 software. The resultssuggest that the Lucite River sub-watershed is not verysusceptible to flooding under normal rainfall conditions, due tothe low values of Drainage Density 0.021, Hydrological Density0.028, Compactness Coefficient 1.92 and Form factor 0.43,presenting an elongated and irregular shape. Although thesevalues do not indicate the need for flood prevention strategies,however in situations of abnormal rainfall, the sub-watershedcould be susceptible to flooding, as some values are close to thethreshold.
