Geography and physical characteristics of the country's Eastern Thai. In General, the Plains River Plains wave undulation the coastal plain slopes. The hills and mountains, with stone floors with curved structures of their era phali o solo Ignatius (Paleozoic) posing with the parallel coast bordering Thai border with Cambodia (Wikipedia. 2553 (2010)) covers an area from South of phetchabun mountain range, and the edges of the Khorat plateau continued to come until the falling edge to keep Thai Gulf through North America, Europe.Chon buri, Rayong, chanthaburi and Trat district and bangboriwen of SA kaeo province of prachin buri, Nakhon nayok and chachoengsao. There are mountains on the southern line of the sector, which resembles an area of plains and mountains between LAT LON. LAT LON area 50-150 meters in height from sea level is moderate (Mean Sea Level) (2550 (2007), Department of mineral resources) By the middle of the region's mountains and high mountains alternating with plateaus and slopes or shopping area. The rest of North-South high mountains including Mount chanthaburi. He is living in the plains area of 1640 m, parallel to the river main line Canal, which consists of plains and river sediments Milan taphak River, which is a different level compared to sea level to medium. The following LAN taphak minimum 5 high river-taphak River 20 meters in the middle of the stage plate (Intermediate Stream Ledge Milan) 20-30 metres high and advanced River taphak (Patio Ledge Advanced Stream) has a height of approximately 30-100 m (2550 (2007), Department of mineral resources) The lower part of the slope is the Centre of the area is similar to the plain. Continued from the mountains parallel to chon buri, Rayong, chanthaburi, ranging from coastal to Trat areas typically have a height 1-50 meters around the coastal area, which is between the smooth mountain slopes in parallel with London area or coastal. Arising from the accumulation of sediment layers (Emptying) from the sea to invade into the Earth. Mountain Plains or areas the original slope roofing Width 5-10 km from the edge of the current area consists of the Thai Gulf, San Sai (Sand Ridge), both old and new, which is caused by the action of sea and wind. Estuary area (Estuary) area of Lagoon (Lagoon) Din Don triangle (Delta) and taphak sea (Sea Milan Ledge) these areas shall have a height of 1-10 m (Raj banthityotthan. 2544 (2001)). the area of estuary and Lands Don triangle. Found at the mouth of the River to the East of the region is the mouth of the bang pakong River. Rayong River. Mae Nam chanthaburi River view and river velu, etc. The area has a height 1-5 meters, mainly areas where flood waters reached at any time or from time to time, which is one of the times every day. The area is both old and new San Sai, as well as the lagoon area will appear as a narrow horizontal space. The West Coast District, Chonburi and Rayong provinces. Height 2-10 m (2550 (2007), Department of mineral resources) Milan taphak sea is highly areas next to the lagoon and sand Ridge area. Appear obvious in Chonburi and Rayong province is smooth until quite smooth. Height 20-25 m (2550 (2007), Department of mineral resources) Issues that affect the region in the long term, it is the coastal erosion, which is an important cause of human activities and natural is the resulting wind waves in the South-East monsoon. High waves caused Tide frequency and severity increasing Cause erosion along the coast, especially the lack of balance of the coastal sand sediments. From a coastal structure changes, such as breakwater, sand and waves. Estuaries Development of the coastal areas, which cause shoreline erosion, such as creating a Habitat. Transport routes Jetty or aquaculture area. Adjusting the reclamation, etc. in addition, the reduction of forest areas and mangrove beaches. It makes the root system in coastal areas due to lack of plant that helps anchor the natural soil sediments. That helps slow the intensity of coastal erosion. Creating piles of rocks against the waves, some areas will result in coastal erosion along the side areas. The lack of management or to solve problems systematically But mainly focus on solving a specific problem and not the view of the overall impact to the neighborhood continuously. Causing coastal erosion problems. To solve the problem that there is no lack of efficiency and sustainability.
