Abstract: The objective of the work was to perform the morphometric characterization of the subwatershed\nof the Horizonte stream in Alegre, ES, from the estimation of some physical parameters. Initially, the\nDigital Elevation Model (DEM) was generated from the topographic maps of IBGE, obtained in the database\nGEOBASES-ES, in the scale 1:50,000, using the geographic information system through the software ArcGis\n10®. The drainage area found was 2.77 km² and the perimeter was 20.23 km. The hydrographic sub-watershed\nof the Horizonte stream has an elongated format and low tendency to occurrence of floods due to the\ncompactness coefficient of 1.585, shape factor of 0.665 and a circularity index of 0.39, an elongation ratio of\n2.42, showing classification of fourth order according to Strahler. The drainage density obtained for the\nwatershed was 2.30 km/km², indicating good drainage of the stream flow, the hydrographic watershed density\n3.37 river/ km² and average length of 83m from the surface runoff.
