Enquadramento de rios e gestão de recursos hídricos. Estudo de caso: bacia hidrográfica do Rio das Contas - Bahia, Brasil.

Abstract

The framing of the water bodies of a hydrographic basin is one of the main management instruments, proposed by the PNRH. The present work aims to analyze the proposal for framing the water bodies of the Rio das Contas Hydrographic Basin (BHRC), using as parameter the CONAMA Resolution 357/2005, also considering the water quality indicators proposed by the Water Framework Directive of European Union - WFD and aims to prepare an Orientation Guide to monitor the effective goals for the framing of BHRC water bodies, based on this study, to be handed over to the Rio das Contas River Basin Committee. To achieve the proposed objectives, the methodology adopted included consultations with secondary bibliographic sources, in addition to considering BHRC as a Case Study, with the analysis of its proposed framework. In total, 52 water bodies were selected to be framed, divided into stretches based on pre-established criteria according to the availability of minimal information. Each Planning region has peculiar characteristics from the point of view of multiple uses and pollution of the springs, having been identified throughout the entire basin a serious problem of sanitary sewage, which made the adoption of a more restrictive classification difficult in some sections. Thus, to make the framework effective, multisectoral efforts are needed to reach the river that can be reached.
