Acesso em:.http://bdm.ufpa.br/jspui/handle/prefix/997The objective of this work was to choose among catchments, which are located in the study watersheds of a research project conducted in the northeast of Pará, those with the highest potential for an evaluation of the relations between land use and water quality in small Amazonian streams. Two strategies were used to select the catchments. The first one was the in situ physic-chemical parameters measurements as follows: Dissolved oxygen, pH, electric conductivity, and temperature. The second approach was related to environmental factors as follows: Catchment area, presence of one predominant land use class, possibility to have pair catchment land use effects evaluation considering biophysical aspects, and logistic aspects regarding to the access to the stream reaches for sampling and measurements. These approaches resulted in a choice of 19 catchments, being eight in the Region 1 (Igarapé-Açu e Marapanim-PA) and seven in the Region 3 (Mãe do Rio e Irituia). In the Region 1 the elected catchments are located in the watershed of the Timboteua and Buiuna neighbour streams, tributaries of the Marapanim River. In the Region 3, the elected catchments are located in the watershed of the Peripindeua Stream, a component of the Guamá River basin. Additionally, it was selected two catchments in forested reference regions (2 and 4) with the same climatic and soil characteristics of regions 1 and 3, respectively.Acesso AbertoIgarapéFísico - QuímicaQualidade da águaPará - EstadoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIASSelecão de microbacias para avaliação da relação entre o uso da terra e a qualidade da água de pequenos igarapés no Nordeste paraenseSelection of small catchments for an evaluation of the relation between the land use and water quality of small streams in the Northeast of Pará StateTrabalho de Conclusão de Curso - Especialização
