CHANNEL PATTERN AND FLOW RATE ANALYSES OF THE JURUÁ RIVER, NORTHWEST OF BRASIL

Abstract

This paper aim to describe the flow rate and fluvial morphology of the Juruá River, Amazonas, Brazil. Using Agência Nacional de Águas (ANA) and Instituto Nacional de Meteorologia (INMET) hydrology and climatology datas. Associated with Landsat and SRTM images interpretations. Thus, according the analyzes, this river in Brazil start with a 559 m³/s mean flow rate in the Porto Walter, gradually increasing until the connection with Taraucá River. Where increase the mean flow rate from 1,832 to 4,227 m³/s in this place. Returning to stabilize from this point to 4,882 m³/s in the last station. According to fluvial morphology, it is classified like a high sinuosity meandering river with high-suspended load and relative stability. Showing sinuosity degree varying from 1.65 from Porto Walter to 3.26 next to Eirunepé.
