Assessment of Fluvial Sediments at Serra Azul Stream, Minas Gerais– Brazil | Chapter 04 | Current Perspectives to Environment and Climate Change Vol. 2
Aims: The goal of this study is to perform the characterization of bottom and in suspension sediments at Serra Azul stream. Chemical, mineralogical and grain size aspects were evaluated, as also the legal issues pertinent to this matter. Study Design: Hydrosedimentological studies at Juatuba basin. Place and Duration of Study: Juatuba basin – southeast part of Brazil, between December 2013 and October 2014. Methodology: The bottom and in suspension sediments of Serra Azul stream were characterized through different techniques: x-ray diffraction, x-ray fluorescence and grain size analysis (using sieves and laser techniques). The environmental legislation was checked in order to see the values of the allowed concentrations of some heavy metals in the waters. Also, the data of a small hydrometric network were treated in order to obtain the natural flows of the water courses. Results: Two elements found in the sediments in suspension were not found in bottom sediments: Chlorine...
