| Summary: | In accord to the principles that lead to the sustainable development the International Council of Scientific Unions (ICSU) says that the science of century XXI must produce integration in front of the environmental challenges in global scale. Among these challenges, it can be distinguish the increasing limitation in the freshwater availability face to the current way of its use The agent of stress of fluvial ecosystems are have large origin and intensity and play inportant role in the destruction and degradation of habitats. The physical and morphologic alterations of the rivers, besides affecting the flow regime, reduce the fluvial corridor and degrade the riparian zone with consequent losses in the biodiversity and the ecological integrity of fluvial environments. In some situations the agent of stress can overshadow the researchs of the effect of the toxicity and the pollution of the waters (Karr et al. 1986). In others, they can evidence that the way adopted in the evaluation and monitoring of the quality of waters, tough valid and viable, are weak and insufficient to promote the sustainable use of the freshwater resources (Miller et al. 1988, Zalewski & Robarts 2003). |
