| Abstract | Historical tsunamis indicate that it occur the most area especially in the Indian Ocean and the South China Sea which is a part of Pacific Ocean. Total death count is approximately around 240,000 – 350,000 people were killed, which some claim has exceeded the combined death toll of all tsunamis over the past 30 years. Thailand is one of the countries that were left devasted from the Indian tsunami disaster which struck on 26 December 2004. Total casualties in six provinces along the Andaman Coast namely, Ranong, Phang-Nga, Phuket, Krabi, Trang and Satun are approximately 5,395 with 8,457 injured and 2,932 still missing. The travel time of the first wave from the epicenter to reach to Thailand is approximately 2 hours. However, tsunami phenomenon may not occur so often but the risks still occur in many coastal areas. Setting up the plan will be helpful to mitigate problems. Using the available resources such as mangrove forest is one way that can be conducted to serve as natural barrier. Mangrove is obviously shown the result in such a way that it reduces the impact from tsunami. This approach is likely become a good choice to conserve the ecological status and also worth to practically build when it is compared with the expensive hard structures. In this study, a hydrodynamic model has been applied to study the magnitude of tsunami propagation and inundation processes in the West of Andaman Coast. The hydrodynamic model has successfully simulated the tsunami pattern. Result of calibration and validation using observed data in 2004 to 2005 showed that the hydrodynamic condition dominated by tidal boundary condition. It is found that tsunami is an extremely event due to the very high fluctuation water level. Hence, the comparison between observed and simulated tsunami wave height came out in such a way that good conformity within the allowable percentage different errors. Tsunami propagation model was found to be a very significant for the formulation of tsunami inundation. It is also very useful to assess the tsunami characteristic on land. The applicability of mangrove vegetation to the field revealed that mangrove is the effective for the tsunami reduction. The designed mangrove model was proposed later on for the assessment landuse. The use of numerical can be explained the tsunami characteristics and model results provide good information lead to the development of buffer zone in the coastal area. |
