BangkokIt is known that there are problems with Bangkok land groundwater for a long time. More recently, it has been raised several issues plague the country as Thai society. With the dissolution of the soil occurs, the pup is at once a huge hole in the middle of the road and up to several feet in Bangkok are often. To collect a variety of information related to groundwater of Bangkok came to read and consider ourselves drowning kanao Bangkok or not? The following is information from a study of the Agency have come to read is too academic. Based on a survey of Department of military maps between 2521 (1978)-2524 (1981) found that Bangkok land had reached most thut each year to 10 centimeters, especially in Phra khanong, Bangna, ladprao Rd., Huamark area, and only at the Ramkhamhaeng University found that in the same period, the land of the groundwater to 1 m at once is considered a very serious level. The research project is lookin womthai-Europe is one of the projects from EU funds. The long name is long and flowing for Geodetic Earth Observation Technologies that Thailand: Environmental Change Detection and Investigation (GEO2TECDI), which is a collaboration of researchers from the Faculty of engineering master's degree in University with the case down male kite, researchers from the Faculty of Aerospace Engineering, Delft University of Technology in Pune, she lookin LAN Earth Geodetic Observa.Tion Technologies for Environmental Change Detection and Investigation: Thailand (GEO2TECDI) the 3 space technology technology support: 1. satellite GPS (the Global Positioning System GPS;) 2. satellite measured sea level (Satellite Altimetry; SALT), and 3. the satellite dan resin (Synthetic Aperture Radar SAR Satellite;) to measure and keep track of changes to the world about your mobile world naplueak vertical phae. Naphon and Pedro from waisumatra other phae note-Andaman. Changes of sea level in Italy, wathai and groundwater chandin/sand area of Bangkok, respectively. In November a year ago. Disclosure of information to come out. ผลการสำรวจตรวจวัดและติดตามการเคลื่อนตัวของแผ่นเปลือกโลกทางดิ่ง โดยใช้เทคโนโลยีดาวเทียมจีพีเอส พบว่า ในช่วง 5 ปีหลังเกิดเหตุแผ่นดินไหวสุมาตรา-อันดามัน ส่งผลให้พื้นที่ประเทศไทยมีการลดระดับของแผ่นเปลือกโลกในอัตรา 11 มิลลิเมตรต่อปี ขณะที่เทคโนโลยีดาวเทียมวัดระดับน้ำทะเลบ่งชี้ว่า อัตราการเปลี่ยนแปลงของระดับน้ำทะเลในอ่าวไทยเพิ่มขึ้นอีก 5 มิลลิเมตรต่อปี ที่สำคัญดาวเทียมเรดาร์ที่ใช้ตรวจวัดการทรุดตัวของชั้นดินทรายในพื้นที่ กรุงเทพมหานคร (กทม.) และพื้นที่ใกล้ชายฝั่งทะเลอ่าวไทย พบว่า มีการทรุดตัวลงถึง 15 มิลมิเมตรต่อปี และคาดว่าปรากฏการณ์นี้จะเกิดขึ้นต่อเนื่องไปถึง 10 ปี (คัดมาจากเวบไซต์ของ มูลนิธิสภาเตือนภัยพิบัติแห่งชาติ) It also includes data from surveys about the groundwater under the Bangkok and vicinity of provincial Waterworks Authority. There is a very interesting details. As follows:The Bangkok subway groundwater is larger and has multiple layers. The water layer that spread up to North Province, Chai NAT. West and East spans the Chao Phraya basin edge South Bay spans into Thai The results from drilling exploration for crude oil found that groundwater beneath the floor, this is a split level 8 in Bangkok, as follows: 1 layer called layer depth 50 meters of water level in Bangkok is the top water and the upper portion of the water floor covered with clay. There are many water quantity water level in Bangkok, but the quality is poor because it is salt water, but the South and southwest of Bangkok that is a brackish water enough to have some 50-60 level in meters.2 layer called layer water cover Red 100 meters of water depth in the water are very high quality, but is somewhat brackish water or seawater are mainly there as fresh water is on districts of the Red cover. Amphoe mueang Samut prakan and Thonburi side boom South, brackish water, and changes to some of the changes to the salt water, and because there are a lot of pumping convenience.3 layer called the Metropolitan water layer. Depth 150 meters is composed of gravel, sand, which prevailed until the province sing buri and towards the East and the West as a water pump is the most widely used because it is definitely both quantity and quality. Wenboriwen thon side lifting and South of Bangkok, where the water is brackish to salty. The pond deeper to Metropolitan water layer can be pumping rate of 100-300 cubic meters per hour.4 layer called layer water area. Depth 200 m water layer is parallel to the Metropolitan water layer. Properties are similar to conditions in the Metropolitan water groundwater. Quantity of water can be pumped up to 150-300 cubic meters per year hours before 2518 (1975) rarely have deeper down the very deep because he comes to make costly. But when the crisis started leading Metropolitan water groundwater. Good quality starts to change. At present, large size, groundwater wells of the Metropolitan Waterworks Authority and large factories have insights into nontha buri water up and then cause groundwater crisis in bangboriwen up now.5 layer called layer-Sam khok This 300-metre deep water layer below the layer area. Most groundwater wells drilled in this class is located in the North, pathum Thani, Nonthaburi Province, the water quality up to close to the water level, there is less water, but it helps.6 layer called the water floor, Phayathai 350-meter deep water layers with this Baker uthok geology and groundwater conditions similar to the water level, there are three specific fresh water sources by Kok North. East and South West of Bangkok. Thon buri district and southern parts are salt water.The water layer is called the 7 floor, Thonburi. 450 meters deep water layer below the ice layer, the thon buri, Phayathai. Groundwater in this layer are fresh and relatively fresh water. Wenboriwen southwest side lift of brackish water as locals. 8 layer called layer water 500 meters of depth near the mouth of the river is the most deep groundwater, freshwater locations. At present, there has been a large industrial drilling wells and pumping water from this water level, particularly in areas where water levels over a shallow layer is salt water, such as a red patch around his district. Samut prakan province. The pond can pump more than 45 cubic meters per hours, and this water floor heating temperature up to 48 degrees Celsius. Therefore, the water pumped will be hot water.
