Abstract
Morphometric and hydrological variables of a river basin are fundamental tools for water quality management within the basin. The paper aims to provide a method for the calculation of morphometric and hydrological variables based on a sub-basins agglutination strategy. The agglutination respects the topology of the existing drainage network within the hydrographic basin according to Shreve's stream order. Preliminary results are provided: TerraHidro system developed at INPE is used to assess a set of variables, in particular, the morphometric variable Gradient Factor and the hydrological variable Maximum Drainage Order of Strahler. An exemplified application is provided considering the Brazilian Brumadinho dam basin| File | Dimensione | Formato | |
