SILVA, Marcela Prado; SANTOS, Franciane Mendonça Dos  e  LEAL, Antonio Cezar. Environmental planning of olga stream hydrographic basin, UGRHI Pontal do Paranapanema - Sao Paulo. Soc. nat. [online]. 2016, vol.28, n.3, pp.409-428. ISSN 1982-4513.  https://doi.org/10.1590/1982-451320160307.

Olga stream is a tributary of Santo Anastacio River, located at Presidente Prudente city in the UGHR- Pontal do Paranapanema - São Paulo. This research aimed to raise the status of environmental conditions in Olga stream basin and thus contribute to environmental planning for recovery, conservation, and preservation. It was carried out literature surveys and assessed basin river characteristics, water analysis (dissolved oxygen, pH, biochemical oxygen demand, total nitrogen, temperature, turbidity and total solids). In addition, making use of remote sensing and Geographic Information System -GIS, were generated maps of use and occupation of land and environmental vulnerability, in order to carry out further research on the environmental conditions of the basin, and to infer possible degradation factors of the watershed.

Palavras-chave : Environmental planning; Hydrographic basin; Olga stream; Santo Anastácio river; Environmental fragility.
