Abstract

The aim of this study was to identify and classify the lake systems of the Araguaia River floodplain. The study area extends from Aruana, State of Goiás, to Luiz Alves, State of Goiás, along 256 km. A total of 293 lakes were identified and grouped in ten categories: abandoned channel lakes, linked abandoned channels, oxbow, filled oxbows, and composite oxbows, lakes formed on meander scrolls, composite lakes on scrolled floodplain, lakes formed by lateral accretion, blocked valleys and embankment lakes. The main objective was to characterize morphometric parameters for 20 lakes in the middle plain of the Araguaia River and compare the different values between high and low river stages. Area, perimeter, depth, length and maximum width, and shoreline development were obtained using satellite Landsat 5 TM and 7 ETM⁺ images and a SPRING Geographic Information System. The variability of morphometric parameters during flood and low river stages changed significantly. Approximately 65% of the lakes showed shoreline development (Dp) > 4 because of the general lakes tendency to have an elongated shape
