MEDEIROS, Rafael; BEREZUK, André; PINTO, André  and  ALVES, Lorrane. Quality of water resources of hydrographic basin of the Formosinho stream, Bonito/MS. GOT [online]. 2020, n.19, pp.03-28. ISSN 2182-1267.  https://doi.org/10.17127/got/2020.19.001.

The objective of this study is to analyze the spatialization and quality of water resources of the Formosinho stream - BHCF watershed. For this, we are following Christofolletti's methodological proceedings (1980) and the rules of Decree 357/2005 by CONAMA (Brazilian Environment Council). That is good to know the karstic geology aspect when we are showing the local water quality and morphometry at superficial water of this river basin. Our results are emphasizing the drainage net good water quality (Class I by CONAMA), however the superficial water flux is scarce with many non-permanent channels (most of them at the underground level), generating the need to develop plans and appropriate management for the dynamics of a karst system to ensure their use for tourism and agricultural activities.

Keywords : Surface water quality; Drainage network morphometry; Karstic systems; Flow velocity.
