FLOOD SIMULATIONS IN RESPONSE TO THE CLIMATE CHANGES IN CENTRAL, VIETNAM Quan Van Dau, MSCE Department of Civil Engineering, Khon Kaen University, Khon Kaen, Thailand Kittiwet Kuntiyawichai, PhD Assistant Professor, Department of Civil Engineering, Khon Kaen University, Khon Kaen, Thailand ________________________________________ Abstract: Flood is a natural feature of the environment and is also one the most frequent hazardous natural disaster. The impacts of flood are highly devastating and usually cause economic depression and direct damages to the livelihood, property, and lives of the people. In recent years, the extended flat territory along the long coastline with the tropical cyclone frequency are results of flood problem in the central region of Vietnam. In an attempt to deal with this adversity, this paper aims to expose the feasibility of assessing for flood simulations correspond to the climate changes. The system was developed using the outputs of the Hadley Centre Coupled Model (HadCM3) for A2 and B2 scenarios and a coupled hydrology – hydraulic model of the basin. Results suggest that the weather gets hotter in…show more content…
(2002). The model developed to transfer the resolution from a large scale predictor variables into local climate variables. For specifying the appropriate predictor variables which are applied for model calibration, the NCEP reanalysis predictors were selected. Predictors are analyzed using correlation analysis and partial correlation analysis to represent the potentially useful of predictor and predictand (rainfall, temperature) relationships. For calibration, rainfall is modeled as a conditional process because the amounts of rainfall depend on wet-day occurrence while the temperature is modeled as unconditional process. Alternatively, a transformation of the “Fourth roots” was applied to account for the skewed nature of the rainfall
