rising sea levels caused flooding of coastal estuaries The sea level rise due to storm caused flooding of coastal areas and break dike, especially storm occur during high tides So the study, calculated and forecasting extreme storm surge in coastal area and flooding risk due to storm are positive tasks to find appropriate solutions for prevention and reduction of damages in coastal areas The components cause extreme water level during storm including tides, storm surge, and wave surge, in which the storm surge is an important one Storm surge is a dangerous natural phenomenon which causes lost lives, destruction of socio-economic infrastructures and valuable resources when typhoon attacking to coastal areas Worldwide, storm surge has caused major damages such as the typhoon in 1970 and 1990 with water surge more than m, generated large wave, inundated to delta of Bangladesh and over 400,000 people were killed On the Caribbean, highest water surge of typhoon Flora is meter, it had cause flood and over 5000 people were killed Coastal of the United States had been affected by historic storm surge of up to 7.4 m The countries on the Northern coasts of Europe had been affected serious of storm surge in 1916, 1953, 1962, 1976, in which the storm occurred in 1953 in Netherland caused large inundation and over 1400 people killed Storm surges may be defined as high sea water level above mean sea level which is caused by strong winds and low atmospheric pressures of a storm Winds which blow towards land exert a shearing stress on the surface, causes an increase in the sea water level near the coastlines Low atmospheric pressure also produces high elevation due to the so-called inverted barometer effect The highest surges have generated by strong tropical cyclones The surge belongs to the same class of phenomena as tide waves and tsunamis Its horizontal scale depends on the parameters of the storm In general, the storm surge occurs in duration of several hours, but it can sometimes last for a few days It is obvious that prediction of surges is a very urgent issue to be addressed, especially in coastal regions which are affected by tropical cyclones There have also been many 10 Figure 35 Inundated mapping of Duong Dong and Cua Duong commune Figure 36.Inundated mapping of Ham Ninh commune Table 23 Flooded area of Phu Quoc island in scenario Flood areas (Km2) District Commune 0-0.5m Phu Quoc Total 0.5 - 1.0 -1.5 1.5 - 2.0 2.0 -2.5 m m m m areas An Thoi 2.281 0.676 0.248 0.103 0.079 3.308 Bai Thom 6.102 0.250 0.188 0.087 0.104

0.188 0.148 0.219 3.037 87 From table 24, we can see that Duong To and Ham Ninh communes are affected more seriously with flooded area of 11.331 km2 and 6.503 km2 The flooded area of Bai Thom and Cua Can is 6.627km2 and 5.148 km2 , Duong Dong has flood area is of 3.037 km2 From figure 34, one can see that inundated depth of more than m can be seen at Cua Can and Duong Dong communes Also in these areas, population density is rather dense and socio – economic activities are deeply developed That’s why if typhoon is comming with high water surge, then damages will be more serious In Ham Ninh commune, inundated depth can be up to level 3, but occurs only narrow strip of coastlines, but it is fishing port of the island with high degree of development and high population, so damages will be more serious Duong To is rather flat topography and coastlines extend both eastern and western coasts, so inundated depth can be 2m and also having largest value of inundated extent In combination with dense population and high economic development, Duong To will become area being the most affaction by storm surge Figure 37 Inundated mapping of D 88 ng To commune CONCLUSION AND RECOMMENDATION Conclusion In recent years, under the effect of the global climate change, natural disaster, specially typhoon and storm surge becomes complicated and caused serious damages to lives properties for coastal areas where subjected directly typhoon and storm surge The appearance of storm surge during the typhoon is one a reason to cause dike break and water overtopping and resulting inundation of land to coastal strip That’s why the study and simulation to quantify the magnitude and process of typhoon and storm surge with their affected parameters in certain coastal areas is very important It help to propose solutions to prevent and mitigate all socio-economic activities in coastal areas and also to make long term strategy for development In this study, Phu Quoc – an island district of Kien Giang province where is very important position in the south of our country in term of defense and security and potential development because of marine resources richness and favorite conditions for socio – economic development, especially in tourism, fishing, aquaculture and seafood processing is selected Based on data collection and investigation on natural conditions, marine resources and environment, socio – economic activities and hydro dynamic data, the following contents have been carried out + General description on natural conditions, climate and hydrodynamic regimes, island’s resources socio-economic development + Literature review on typhoon and storm surge have been done by foreign and Viet Nam authors + Presentation on the methods used to study and assess the storm surge due to typhoon and finally to select DELFT3D for this study in Phu Quoc island + After deciding the method used for study, the model domain is set up; Typhoon Linda approached in study area in 1997 was selected to study storm surge; calibration and verification to find the model parameters + Based on the typhoon scenarios built up by MoNRE and approved by Viet Nam government, scenarios is selected and the simulation to compute storm surge has been done according to typhoon’s scenarios 89 + selected scenarios are as following: (1) Scenario 1: Simulation of typhoon namely Linda that approached to the study area in November, 1997 (2) Scenario 2: Scenario in case of the typhoon Linda coming at the same time of flood tide at the study area (3) Scenario 3: Simulation of typhoons according scenarios approved by Ministry of Natural Resources and Environment (MoNRE), but wind velocity changes with the time V= f (t) After having the results of simulated water level for all scenarios, ArcGIS software is used to compute inundated situation including inundated depth, spatial extent and its duration The risk assessment is carried out for all scenarios The results taken after the simulation can be summarized as following: + With the Linda typhoon attacking the Phu Quoc, storm surge seems to small and inundated is very small The damage happened in this typhoon caused mainly strong wind only + In second scenario, resultant water level is liter bit higher in southeast and east sides of islands belonging Ham Ninh and Bai Thom communes while western coasts is small affected by storm surge + In third scenario, resultant water level is much higher in second scenario occurring all around the island, but higher in the south both east and west coasts and gradually decreasing to the north at Bai Thom commune The combination between inundated depth and degree of development for each zone, it can see that Ham Ninh, An Thoi, Duong Dong and Duong To have high potential risk when typhoon coming to the Phu Quoc island Recommendation By statistics, the typhoon approaching to the study areas is rare, one for a year or/and one for every some years, so the selection of real typhoon in order to calibrate and verify is limited and scenarios is selected basing on decision of government Due to limited observation stations in Phu Quoc island and surrounding, so it is very difficult in calibration and verification to define the model parameters Due to the map scale, the inundated map is not in detail and inundated parameters such as spatial distribution of certain flooded depth, its extent and temporal distribution etc 90 That’s why above study gives general pictures of inundation and potential risk assessment I hope that these problem will be improved in further study 91 References [1] Atkinson, G a (1977) Tropical cyclone minimum sea level Monthly Weather Review, 421 -427 [2] Banton, J S (2002) Long term variability of hurricane trends and a Monte
