Recently, the frequency of water disaster occurrence and the scale of damage have increased due to the climate change. However, technology for effectively monitoring the flooding situation and the damage aspect is still insufficient. Since various studies are actively conducted on utilizing unmanned aerial vehicle (UAV) in the field of geospatial information, the utilization of UAV is expected to improve the timeliness and accuracy of flood monitoring. This study conducted a flood situation monitoring at Gap River on July 30, 2020 using UAVs. The comparison between the water boundaries derived from UAV images and hydraulic model simulations (FLUMEN) were performed. Results showed that the water boundaries simulated using FLUMEN only resulted to 2.85% difference with UAV images derived water boundaries. Thus, verifying that the UAV images can be used to provide supplementary data in providing spatial extents of stream variables. This study aims to introduce the technology for performing quick flood monitoring and the possibility of its utilization in flood inundation simulation.
