ABSTRACT:
The implementation of the Brazilian National Water Resources Policy emphasizes the systematic planning and management of water resources without dissociating quantity and quality aspects. This also requires strategies that consider appropriate socio-economic-environmental boundaries to encompass the diversity of the Brazilian territory and to promote integration of water resources, environmental planning articulated with land use management, different users and all distinct regional, state and national actors, in a given watershed. This paper highligths the necessity of a technical base for integrated water management that considers also land use and territorial management in critical basins. The environmental regulation allows for the definition of water quality goals defined in a progressive manner to achieve proper restoration of the water body to comply with designated uses. The definition of such restoration steps must be defined in accordance with territorial management perspectives and based on sound technical and scientific methods that include risk analysis perspective.
Key words: Upper Iguaçu Basin, progressive goals, mathematical modeling
