Abstract

This work aims to evaluate the application of geotechnologies in the construction of Digital Surface Models (DSM) for two washouts located at Cassino Beach, Rio Grande, RS. The use of geotechnologies such as remote pilot aircraft (RPA) and GNSS-RTK receiver resulted in the construction of six DSMs, two for each flight day, of channels with Ground Sample Distance (GSD) between 5.05 cm and 5.26 cm. We emphasize that the use of RPA and application geoprocessing techniques are of great value in the improvement of studies on the coastal areas and washouts of the Cassino beach.


Keywords: geotechnologies, coastal geomorphology, washouts, drone.
