Abstract

This paper introduces the results of 3D flooding in Long Khanh village, An Hoa commune, An Lao district, Binh Dinh province in Lai Giang river basin based on Unmanned Aerial Vehicle (UAV) technology and hydraulic modeling of HEC-RAS, and GIS technology. The boundary data of the hydraulic model is calibrated and verified with actual flow and water level data measured at An Hoa station corresponding to the historical flood in December 2016. The 3D simulation results of the flooded area have shown in great detail the flooded area, flood level, as well as velocity. In addition, the paper has proposed to use the level of detail and the extent of the area needing 3D simulation of the flooded area in the study area.
