Abstract: A análise granulométrica de sedimentos arenosos pode ser realizada através de diferentes técnicas como o peneiramento, a decantação, a difração a laser ou ainda a análise de imagens digitais. A técnica de análise de imagens digital vem sendo difundida por ser considerada a de mais baixo custo, contudo, a maioria dos trabalhos que descrevem o método utilizam programas de computador complexos e pagos. O objetivo do presente trabalho é descrever e avaliar um protocolo metodológico de fácil acesso e baixo custo ut… Show more

“…One study [23] evaluated the methods of sieving and densimetry for soil samples and verified that sedimentation quantified more accurately the sand, silt, and clay fractions, agreeing with the results obtained among the studied methods. Another study [24], in turn, compared the methods of image analysis and laser diffraction through analysis of variance, and found no statistical difference between these methods. Regarding the textural classification of the studied compositions, differences between the clay, silt, and sand fractions for the evaluated methods were identified, mainly due to the differences between the physical principles used by the techniques to obtain the spherical particle diameter, which determines the final analysis result.…”
