Abstract
The environmental question rose up in the global scenario, when developed countries
perceived that the economic grow up resulted in waste and impoverishment of natural
resources. Several events were realized to implement a global environmental policy, which
aimed conservation and sustainability of natural environments. In what concerns hydro
resources, Brazil implemented the first water regulamentantion named código das águas , in
1934, wich was limited. Only in 1997 a complete proposal on water resource management
was developed. The Policy of Hydrological Resources adopted in Brazil is executed centered
on the Hydrographic Basins. In this respect, the present study concerns the Bay of Guanabara
basin that possesses16 municipalities. The sub-basin of the river Imboaçu is part of it, and is
totally localized in the urban area of the Municipality of São Gonçalo (RJ). Thus in the same
way as the municipality, the sub-basin is heavily peopled, and the river highly degraded in
most of its extension, not even being recognized by the nearby inhabitants as a river, but yes
as an open-sky sewage. The river Imboaçu is however still navigable near the mangrove, and
is used by fishers to reach the Bay of Guanabara. Its sources are still well preserved, being
even used by neighbor s people, as those sources are found in a conservation unit, the
Environmental Municipal Protection Area of Engenho Pequeno (APAM-EP). This work
brings a detailed socioenvironmental and socioeconomic study of the river Imboaçu subbasin,
describes two new sources, two new affluents not found on the map, elaborated the first
map of the APAM-ES and comes up with a proposal to contribute to the management of the
sub-basin, a proposal that might even be broadened to the entire municipality.
