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 causing economic depression and direct damages to
the livelihood, properties, and lives of the people. In recent years, the
extended flat territory along the long coastline with the tropical cyclone
frequency is result of flood problem in the central region of Vietnam. In an
attempt to deal with this adversity, this paper aims to manifest the feasibility
of assessing flood simulations that corresponds to the impacts of climate
change. The system was developed using the outputs of the Hadley Centre
Coupled Model, version 3 (HadCM3) for A2 and B2 scenarios and a
coupling of hydrological – hydrodynamic models. The results indicated that
the weather will become hotter in the future with the increase of temperature
between 0.4°C to 2.2°C and 0.19°C to 0.6°C under A2 and B2 scenarios,
respectively. On the other hand, the annual rainfall will also increase
between 3.3% to 14.5% and 3.6% to 6.8% under A2 and B2 scenarios,
respectively. The results also demonstrated that potentially serious increases
in runoff and water level under future climate change scenarios. The
unanticipated consequences might play a large role in destruction of crops,
transportation, water supply, and communities located in the Huong River
Basin. Additionally, the outcomes of this study can be applied for the entire
Huong River Basin in order to mitigate the flood problems in the future.
