Abstract
    This bathymetric survey was performed in iron ore and pellet extracting industries, one of which located in the Southeast and the North of Brazil. The survey was accomplished with a single beam and a DGPS for real time positioning; the software was Hypack version 4.3a Gold. The TIN method was employed for a better understanding of the submerged features and of the superposition in the satellite image. The images were used for planning the survey lines, the real time sailing and the final plotting. The conclusion is that the use of a comprehensive amount of resources to perform hydrographic surveys provides better chances of obtaining precise results of dam monitoring and hydrographic follow-up, with the best possible precision ratio between the acquired and the presented data.
