Morphometric parameters of the relief and drainage network of a tropical subbasin

This research analyzed the morphological/morphometric parameters of relief and drainage network Formiga River subbasin, southern Minas Gerais State, Brazil. study identified examined influences control mechanisms in development current configurations. The methodology was based on application indices parameters: (1) slope length (Hack's Sl); (2) normalized index (ksn); (3) river hierarchy; (4) density; (5) hydrographic (6) sinuosity index; (7) density structural lineaments; (8) transverse topographic symmetry factor; (9) asymmetry factor basins; (10) profiles to valleys; (11) ratio; (12) roughness (13) concentration (14) compactness coefficient; (15) circularity (16) form factor. results indicated 3 sectors subbasin with distinct geomorphic behaviors, which resulted peculiar surface structures divergent dynamics. presents physical evidence that demonstrates corroborates strong tectonic relief. Human action has also affected, from construction dams, dynamics lower course river, drowned by reservoir hydroelectric plant Furnas.
