Abstract
This study examines the usability of unmanned aerial vehicle (UAV) data surveyed just after an agricultural reservoir collapse by comparing the survey results with the simulation results of the HEC-RAS (Hydrologic Engineering Centers River Analysis System) flood wave propagation to the downstream areas. A 61,400 m 3 storage dam broken by 89.0 mm (over 30.0 mm/hr rainfall intensity) of rainfall on August 21 st , 2014 was considered. The reservoir water capacity curve and downstream damaged areas were estimated by drone surveying 3 days after the dam break. The flood wave by the overtopped dam break was propagated using the HEC-HMS (Hydrologic Engineering Centers Hydrological Modeling System) reservoir inflow from the watershed. The model results showed flood inundation depths of 0.1 to 2.2 m, mainly in rice paddy areas along the stream, and the overtopped dam-break scenario exhibited 59% correspondence with the drone-surveyed areas.
