Thailand Landforms

The Thailand landforms are represented by lakes, mountains, rivers, bays, plateaus, peninsula, plains, islands and isthmus.


The highest point is Doi Inthanon, with 2.576 metres and the lowest is the Gulf of Thailand with 0 metres. There are 4 main geographical regions in Thailand: the Central alluvial plain interrupted by hills and roamed by the Menam River, is limited at North and West by mountains with medium altitudes, made of parallel chains.


To East, separated by the Menam Plain through a mountainous chain, is the Khorat Plateau, sandy and with low altitudes, leaning toward the Mekong River.


The fourth region is made of mountainous chains separated by large aisles. The Khorat Plateau is situated in the Thailand’s North -East and its name comes from the area’s biggest city, Nakhon Ratchasima, also known as Khorat. The average covers a 155.000 kilometres squares area. The Chi and the Mun rivers drain the plateau, both Mekong’s tributaries.

The Phetchabun mountain range separates Mekong from the Central Thailand and the Dongrek mountains separates Mekong River from Cambodia. Among the mountains of Thailand are: Doi Inthanon, Khao Mae Ya, Doi Lang Ka, Doi Chang, Doi Pui, Doi Tung, Phu Khao Thong or Doi Nang Non.


The Thailand Gulf, also known as the Siam Gulf is situated in the China Sea (the Pacific Ocean) and is surrounded by Thailand, Vietnam, Cambodia and Malaysia. The extreme North of the Gulf is at the Chao Phraza River’s flooding, in the harbour from Banqueocoque. The gulf has a size of 320.000 kilometres squares.


The Thailand Gulf is not very deep, with depths between 45 and 80 metres. This thing makes the water’s circulation slow and the Mekong and Chao Phraya Rivers to exert a strong influence such as: low salinity and a big richness of sediments. During the cold eras like the Ice Age, Thailand Gulf didn’t exist because of the small depth, it was just a continuation of the Chao Phraya River.


Due to the tropical heat, the gulf’s waters hold a big quantity of corals, existing some projects to develop the tourism in the Ko Samui Island in the Surat Thani province. The gulf is also rich in petroleum and gas. The Oriental part of the Khra Isthmus belongs to Thailand and the Occidental part belongs to the Tanintharyi province from the Myanmar. The isthmus is laved at east by the Thailand’s Gulf which belongs to the South China Sea and the Occidental part of the Khra Isthmus is laved by the Andaman Sea. The tightest part, situated between the Khra River’s estuary and the Sawi Gulf, next to Chumphon, has a width of 44 kilometres.

Its maximum height is of 75 metres above sea level. The isthmus has the name of the Thai city Kra Buri, situated on the West coast of the land narrowing. The Khra Isthmus marks the border between two parts of the mountainous chain that comes from Tibet and that crosses the entire peninsula.
