Sea Level Rise in Rayong province in the year of 2021 - 2099
Keywords:
Sea Level Risk, HadGEM2-ES, Geographic Information System, Sea LevelAbstract
Sea level rise is a major global problem as a consequence of global warming. This research aims to study climate change on sea level rise in Rayong province during the years 2021-2099 using spatial data, GMTED21000 numerical altitude data and the HadGEN2-ES global climate model were used to calculate precipitation and average annual temperatures and using spatial raster calculation method for determining the volume of sea level rise in 8 periods. The results were showed that the highest mean annual precipitation was in 2092 (164.21 mm.), and the lowest was in 2090 (108.77 mm.) 2080 with 27.82 C° and the mean minimum temperature appears in 2026 at an average temperature of 26.13 C°. In addition, during the year 2092-2099 the highest increase was 0.2528 m. representing an increase in water volume of 4,266,000 m3 (35.05%), followed by the years 2080-2091 with an increase of 0.2208 m., representing an increase in water volume of 3,726,000 m3 (30.61%). Moreover, areas affected by sea level rise was found that the sub-district that was most affected was Thang Kwian and Pak Nam Pran followed by Khlong Pun, Pang Rad, Noen Kho, Map Ta Phut, Noen Phra, Pak Nam, Tha Pra Du, Choeng Noen, Phe, Phe, Klaeng, Sak Phong, Kram, and Kong Din sub-district respectively. Relevant agencies should prepare to deal with sea level rise in order to prevent future hazards.
