                         monitoring enabling the survey of the main impacts and helping in 
                         the adoption of mitigating measures. The current study were 
                         monitored sedimentary processes at the mouths of the 
                         Canan{\'e}ia-Ilha Comprida-Iguape Coastal System. Landsat TM-5 
                         satellite images from the years 1987, 1991, 1993, 1997, 2005 and 
                         2010 were used. The images were digitally processed in SPRING. A 
                         separation of land and water was carried out on satellite images, 
                         from the mouths of the Ribeira de Iguape River and the Icapara 
                         mouth, in order to delimit the coastlines. They were compared 
                         multitemporally in order to analyze spatio-temporal evolution. For 
                         each year non-linear edge detection filter Sobel was applied. The 
                         mouths of the study areas presented intense sedimentary dynamics 
                         during the analyzed period. Bathymetric surveys conducted in the 
                         study area indicated greater depths located in the stretches where 
                         the channels are narrower and in meander areas of the lagoon 
                         channels, confirming the importance of these data for the 
                         understanding of the erosive processes in the region. The 
                         monitoring of the mouths of coastal systems should be considered 
                         as a necessary measure because they are extremely dynamic areas in 
                         terms of sedimentary processes often subjected to inadequate human 
                         occupation. From the present study, it is suggested the 
                         application of the filter for edge detection in the processing of 
                         satellite images to monitor the dynamics of the mouths of coastal 
                         systems by managers of Conservation Units and other actors 
                         involved in the management of the Brazilian coast.",
