BUFFON, Elaiz; SAMPAIO, Tony  e  PAZ, Otacílio. Unmanned Aerial Vehicle (UAV): application in the analysis of floods in urban areas. GOT [online]. 2018, n.13, pp.85-108. ISSN 2182-1267.  https://doi.org/10.17127/got/2018.13.004.

The flood risk assessment can be carried out considering, in an integrated way, the processes resulting from physical pressures (hazard assessment) and weaknesses (vulnerabilities). Currently, the geotechnologies, in particular the UAV, allow analysis of environmental problems in real time and with high precision. In this perspective, the objective of this work is to present a methodological approach for the evaluation of the built-up areas potentially affected by urban floods. For this reason, primary data in the study area (Campo Magro-Paraná, Brazil) were collected through UAV and field work, which subsequently allowed, with the support of Geographic Information Systems, to build a synthesis mapping of disasters risk. The results indicate that the methodology is cost-effective and important for the areas devoid of detailed imaging, and has proved to be efficient as a spatial decision support system for risk mitigation and prevention of the disasters caused by floods.
