COASTAL TOPOGRAPHY

Adjacent to the western part of Thailand wher 6 provinces, which are Ranong, Phuket, Pang-Nga, Krabi, Trang and Stun, situated lay Mianmar, Andaman Sea and Malaca Strait of the Indian Ocean. This coastline is open for the southwest monsoon especially from May to September, during when it is quite the stormy season of the year.

The coastlines with no islands to keep the wind off have steep beaches with deep sea near the shores. Those with islandsaround the beaches or those with gulfs not fully open to monsoon contain muddy soil and are filled. with muddy woods along the coasts such as Red and Black mangrove.

Significant rivers where the cargo coasters can pass into are Kraburi and Trang. Various salty
canals have been developed from canals and streams that flow into the sea when the tide is
rising.

Along the coastal lines located more than 200 small islands. Most of them are steep and rocky
islands. Several of them are isolated rocky towers, which are not appropriate for dwellings. This coastal side contains two important ports. Phuket Port is the natural port where cargo ships have anchored for loading/unloading since ancient times. Gan Tang Port lies on Trang River andGan Tang Canal.

The territorial sea joint between Trang and Krabi is lined up with various small and big islandsone after another, especially at the Lanta Islands National Park in Krabi, where the exquisite islands like Rok Islands and Ngai Islands are situated.
