Include [ 1] 1. Bangkok 2. Nat 3. Nonthaburi 4. Thani 5. Ayutthaya 6. Lopburi 7. Sara 8. Sing 9. Ang topography mainly consists of plains which caused the river to blow out debris. dirt, gravel, sand and silt deposition to accrue since the time of millions of years in this sector ranged from the plains of the southern province of Uttaradit down to the Gulf of Thailand. It is a flat area with five lakes than any other region of the country, however, some areas of the region is the lone mountain and the western province of Phitsanulok. From geological evidence Presumably these mountains used to be an island stand. The flood waters reached the offense in several eras. The ground swell up As well as the actions of many river which has eroded erosion and sediment deposition. This causes the vast plains of the country, considering the structure. The region can be divided into three zones. Is 1. North Central Province to include the area from the upper. Phichit, Phitsanulok, Kamphaeng Phet Province, covering an area in the county, including some in Sukhothai, Phetchabun. The terrain is generally in the upper. Approximately two in three areas of the river plains and plateaus, corrugated ( rolling. plains) , which is caused by the action of major rivers is the River Ping, Wang, Yom River and the Nan River tributaries corrugated terrain that may result from the river swept out the rubble, gravel, sand and silt at large. Before deposition of sediment If the sediment already. The first type is resistant to corrosion than the latter. It became like undulating terrain. A switch on the low hill area, easy to wear. The trenches have become a plain corrugated. This action also causes the plains of river terraces ( terraces) lowlands, river or floodplain ( Flood. plain) of the Ping River and Nan River on the east side of the county's terrain is hilly and mountainous stretch the boundaries of the Northeast. These include the Cordillera mountain range of Phetchabun two which continued from Luang Prabang Range. Phetchabun mountain range between 1 to Phetchabun mountain range two narrow plain in the Municipality and Phetchabun. This river flows through the plains to the south. Phetchabun mountain range, two are mostly rocky Andes site. Stone Oak Wright's Terry Shea Creek. On the western side of the mountains is flat foot switch the low hill to the river plains abutting 2. South Central. From the plains of the southern province of Nakhon Sawan down to the Gulf of Thailand. Terrain lower central area of the river delta. Most of the sediment that the river Chao Phraya, Tha Chin river. And washed down to the river These rivers flow through the area on the plain. The speed of the current is reduced to objects of dissolved contaminants in the water to sedimentation deposition. These sediments which mainly consists of sand, clay and silt sediment, partly in the river mouth area. Sediment deposits from the shore out to more than 1.5 kilometers. And also caused the river delta. The barriers to water transport is very river This is because soil can absorb water. The thickness of the layer of sediment in some areas where drilling for geological exploration. Found that some of the thick over 120 meters. So will the shale ( Dedrock) below 3. Edge plain ( Plain marginal) , including terrain is predominantly flat with some narrow area in the western province of Uthai Thani, Suphan Buri and Nakhon Pathom and some areas in the eastern province of Saraburi and Lop Buri. The landscape is as different from the Nile River in the geomorphology. This is because the eroded rock into soil and water as the soil makes these rocks deposited in the foothills. And the line of the river basin when comparing the characteristics that differ. The western area of the province. Especially in Samrong district The switch is a flat low hill which this area eroded from limestone ( Generating sets ) slate and shale soil is dark gray to black. In addition, in some areas there are patches of rocks broke up with basalt and stone Andes with contaminated sites. Some of its iron ore, as he crushed Buffalo. Lopburi Lopburi The area bordering the plain two sides. Current sources are important in the wake of plants such as corn, sugarcane, sorghum, cassava and others became an important crop in the country's demographics in Central Province based division of the Royal Academy of the Province of ( people ) ( 31 December 2557. ) [2] of ( people ) ( 31 December 2556) [3] of ( people ) ( 31 December 2555) [4] many ( people ) ( 31 December 2554) [5] of ( people ) ( 31 December 2553) [. 6], one of Bangkok 5,692,284 5,686,252 5,673,560 5,674,843 5,701,394 2 years 1,261,530 1,241,610 1,223,302 1,209,405 1,185,180 3 Nonthaburi 1,173,870 1,156,271 1,141,673 1,122,627 1,101,743 4 Pathum Thani 1,074,058 1,053,158 1,033,837 1,010,898 985,643 5 Sawan 1072,756 1,073,142 1,073,347 1,071,686 1,073,495 6 Phetchabun 995 807 994 397 993 702 990 807 996 031 7 Pathom 891 071 882 184. 874 616 866 064 860 246 8 Phitsanulok 858 988 856 376 854 372 851 357 849 692 9 Suphanburi 849 053 848 066 847 308 845 053 845 850 10 Ayutthaya 803.599 797.970 793.509 787.653 782.09.
