Topography and physical eastern Thailand. Typically the river plains. Plain, wavy Coastal plain Mountains and hills There are stratigraphic, structural bending of the Paleozoic (Paleozoic) position parallel to the coast until the border between Thailand and Cambodia (Wikipedia. 2553), covering the southern part of the Phetchabun mountain range and edges. Khorat Plateau continued down to the edge of the Gulf of Thailand in Chonburi, Rayong, Chanthaburi and Trat. And some areas of the province and Nakhon Nayok. The mountain lines in the upper portion. This is a flat area between the mountains slope roofing. The wave slope height 50-150 meters from mean sea level (Mean Sea Level) (Department of Mineral Resources, 2550) in the central region has a high mountain range and the plains and the wave slope. Situated in the north - south high mountains, including the Sierra Chanthaburi. With his uppercut 1,640 meters high plains along the river Main. Consisting of alluvial plains and river nearby ledge. This is a different level compared to the average sea level patio ledge below the minimum height of 5-20 meters lawn river ledge Stream intermediate (Milan Intermediate Ledge Stream) 20-30 m high and patio ledge Advanced Stream (Patio Ledge. Advanced Stream) with a height of 30-100 meters (Department of Mineral Resources, 2550), the lower part is a switch to a flat slope roofing area. Continuation of the mountains along the coast from Mass to Trat. Area generally has a height of 1-50 meters of the coast is flat in the foothills or the wave slope parallel to the coast. Caused by the accumulation of sediments (Emptying) from sea water penetration into the earth. Flat foot or the original wave slope with a width of 5-10 km from the edge of the Gulf of Thailand. Consists of sand dunes (Sand Ridge), both old and new. It is caused by the action of the sea and wind. Estuary area (Estuary) area Lagoon (Lagoon) Delta (Delta) and patio ledge Sea (Milan Sea Ledge), these areas will have a height 1-10 m (Royal Academy. 2544). The area estuary and delta. Found in estuaries on the east side of the river mouth, Chanthaburi and Rayong River, river runoff, rivers and river Welu area has a height of 1-5 m, mainly in the flood waters at all times or at any given time. time every day Where the dunes, old and new, including a lagoon. Will appear as a narrow zones. The west coast in the province of Chonburi and Rayong, with a height of 2-10 meters (Department of Mineral Resources, 2550) is an area of high ground sea ledge next to the dunes and lagoon. Appears to be more pronounced in Chon Buri and Rayong. A flat surface until fairly smooth, with a height of 20-25 meters (Department of Mineral Resources, 2550),
the long-term impact on the region is coastal erosion. This is mainly due to natural and human activity is the cause waves in the southeast monsoon season high tidal waves, the frequency and severity increases. Cause coastal erosion. The imbalance of sand coastline. By structural changes such as dams, coastal sand and surf. Estuary The development of coastal areas, causing coastal erosion, such as creating a living. Interactive Wharf or aquaculture space reclamation adjustment, etc. Also, the decline of mangrove forests and beaches. It makes the coastal areas of the plant roots help hold the soil naturally. This helps soften the severity of the erosion. Creating a heap block certain areas. Will result in the erosion area side. Lack of management or problem-solving system. Most focus on solving specific problems of any one without looking at the problem as a whole. It will affect the neighborhood continued. Contributes to the problem of coastal erosion. To fix the inefficient and sustainability.
