Abstract

The present work uses a modern generation of side scan sonar aiming to obtain sonographic images of the coastal region of Barra Grande River, located in the Dois Rios Creek, Ilha Grande, SE Brazil. This technological advanced technique has enabled to obtain sonographic imaging of ultra-shallow areas, at depths between 1 and 5 meters in the study area. From the obtained records and the sonographic patterns, seven areas / features closely related to characteristic sites and / or processes observed in the low fluvial course were identified. This mapping allowed to correlate the features observed in geological, geomorphological, hydrological and sedimentological studies in Ilha Grande, making possible the analysis of the final portion of the Barra Grande River course, in the coastal plain of the Dois Rios Creek, on this island.
