%X The creation of small and medium size dams in river systems is a common practice in rural properties in Brazil, aiming to guarantee water resources for agricultural irrigation, power generation and vacation/sport activities. Most of these interventions are done without environmental license, nor technical accompaniment for their construction. This fact presents high risks for Brazilian society, such as those arising from recent and tragic events in Minas Gerais state (the case of the Fundão dam, in Mariana region) and in Goiás state (disturbance in dam at the municipality of Itaberaí). Unmanned Aerial Vehicles (UAV) have been used to monitor such areas, before and after the geographic accidents, presenting as the best proposal between satellites and manned airplanes, due its high spatial resolution, price and mobility. Thus, this study aimed to evaluate the use of a UAV to evaluate the environmental damage of the dam break in Itaberaí - Goiás, which occurred in February 2016. The UAV used in this study was the Swinglet CAM from Sensefly, an electric microvant equipped with a 12.1 megapixel RGB digital camera. The results are very promising, enabling the generation of precise georreferenced orthomosaics and the identification of the permanent preservation areas damaged (26 hectares), the original area of the dam (48 hectares) and the total flooded area (76 hectares), favoring the process of forest restoration and the public supervision.
