The present work has the goal of obtaining and gathering pieces of
information from the inside and surrounding of Jacarepaguá Lagoon, Rio de
Janeiro, and to make models to help in the governmental management of the
area, that is so featured because of its population growth and its visibility due to
sporting events that will take place in this location, specially the 2016 Olympic
Games. Two models have been made, bathymetric and geological ones, which
followed the same work methodology: data collection, development and
validation of the model through geophysical survey using georadar. For the first
model a bathymetry was done in Lagoon getting georeferrenced depths on field
to elaborate 3D and 2D models of depths, in order to identify ditches originated
from dredging of embankments of actions on its borders. Finally, GPR (Ground
Penetration Radar) surveys were made on the inside of Lagoon with the purpose
to compare the predetermined sections of the model. Although the radargrams
did not show good results due to the water electric conductivity, the water was
still saline despite the distance of the ocean. The second model was developed
based on data from pre-existing surveys of the area that achieved 3D models,
lithological and cronostratigraphic, where transverse sections were done so that it
could be possible to obtain a better space visualization. The validation of this
model from the comparison of GPR sections with sections extracted from the
model, obtained satisfactory results, complementing the geological processed
model interpretation. From this geological model, layers were identified in specific
depths, locating concentrated zones of soft soils on the studying area.
