EFEITOS DA EXPANSÃO URBANA NA MICROBACIA DO RIACHO CAPIVARA, IMPERATRIZ – MARANHÃO

Abstract

This work aims to study the urban expansion process and the effects of this occupation in the microbasin in the Capybara Strean in the town of Imperatriz-MA and propose subsidies for the discussion of public policies for environmental preservation. In the recent past this microbasin was an available water source, but urban growth has led to degradation of this stream. Contamination of surface water from this source will be detected by physicochemical analysis of water: temperature, pH, Conductivity, Turbidity, Dissolved Oxygen and colorimetry, through data collection at six points along the stream. The results indicate the degree of contamination the stream and what measures can be recommended for to soften the effects of the urbanization process.
