Resumo: | In the last decades the development of new technologies has brought about a great advance in science. In geotechnologies, one of the biggest advances was the development of Unmanned Aerial Vehicles that allow obtaining high quality data, with great potential for use in geomorphology. In this work, data obtained with aerial survey with UAV were used for the morphometric analysis of Voçoroca do Areal in Cacequi - RS. For this purpose, a flight was performed with a multirotor UAV, Phantom 4 at a flight height of 150m, afterwards the data were processed using the Structure from Motion algorithm. Afterwards, gully advance areas were classified and several morphometric parameters were calculated. The gully has different dynamics in different portions, having in the area upstream more extended and long areas of progress with smaller depths, in the central portion a large vertical development with a large eroded volume and in the downstream areas, with less intense advancement areas. Finally, the data obtained allowed the analysis of Voçoroca do Areal morphometry, providing data with extreme quality and accuracy. The use of these new geotechnologies still has a lot to contribute to the geomorphological analysis, mainly in the detailed mappings. |

Nas geotecnologias um dos maiores avanços foi o desenvolvimento de Veículos Aéreos Não Tripulados (VANTs) que permitem a obtenção de dados de alta qualidade, tendo um grande potencial para o uso na geomorfologia. Neste trabalho, foram utilizados dados obtidos com aerolevantamento realizado com VANT para a análise morfométrica da Voçoroca do Areal em Cacequi-RS. Para tanto, foi realizado um voo com um VANT multirotor, Phantom 4 a uma altura de voo de 150m, posteriormente os dados foram processados através do algoritmo Structure from Motion. Em seguida, foram classificadas áreas de avanço da voçoroca e calculados diversos parâmetros morfométricos. A voçoroca possui dinâmicas distintas em diferentes porções, tendo mais a montante áreas de avanço mais alargadas e longas com profundidades menores, na porção central um grande desenvolvimento vertical com grande volume erodido e na porção mais a jusante áreas de avanço com menor intensidade. Por fim, os dados obtidos permitiram a análise da morfometria da Voçoroca do Areal, fornecendo dados com extrema qualidade e acurácia. A utilização destas novas geotecnologias ainda tem muito a contribuir com a análise geomorfológica, principalmente nos mapeamentos em nível de detalhe.
