Application of Mike11 and remote sensing in simulating flood - a case study in Tra Khuc River, Quang Ngai Province, Vietnam

Flooding, inundation are two of five kinds of disaster (storming, erosion, drought, saline intrusion) which cause serious impacts on Vietnam. In addition, due to the effects of climate change, unstability and more serious disasters in term of frequency, locations, and intensity. In this problem, central of Vietnam, especially Quang Ngai, are famous examples. This study applys combined approach: remote sensing method for establishing flooding maps and MIKE11 for simulating flood in Tra Khuc river downstream. The research aims to provide scientific and practical basics for projects and sience missions. The data is provided from historical flooding event in Quang Ngai in 2013, the article presents results including (1) Map of flooding in Quang Ngai in 2013 with correlation coefficiency at 0.87; (2) Hydrological and hydrodynamic caribrated parameters for MIKE11 for downstream area; (3) Maps of inundation in 2013 for Tra Khuc downstream; (4) Potential flooding risk maps following climate change and sea level rise scenarios.
