Project: “Investigation and assessment of groundwater in the mid-land and mountainous areas of Bac Bo”

Objectives:

- Assessment on the potential and capacity to meet the demand of groundwater in accordance with the requirements of social economic development and national security until 2010, which will be the background for the planning, appropriate exploitation and protection of groundwater in the mid-land and mountainous areas of Bac Bo;

- Combination with the supply of drinking water for several points/ areas which are urgently in need of water in the mid-land and mountainous areas of Bac Bo;

Implemented by: 3 Divisions for Water Resources Planning and Investigation of the North, the Centre and the South and the Sub-center for Water Resources Consultancy and Services from 2006 to 2009;

Completed activities: collection of data; analysis and processing of remote sensing pictures; general investigation and survey; investigation and collection of data on current status of water exploitation and utilization, discharging of waste water into the water sources (groundwater, surface water and waste water), carrying out hydrological survey and drawing, geodesics, geophysics etc.

Investigation and survey and drawing of hydrogeological map at the scale of 1:50.000 for 57 investigated areas of 8 provinces (Cao Bằng, Nghệ An, Bắc Kạn, Hà Giang, Lạng Sơn, Thanh Hoá, Thái Nguyên, Bắc Giang) covering an area of 2.977km2, 85/111 constructed wells (76,6%) has the discharge of 0,5l/s, total discharge of 267,1l/s equal to 23.076m3/day. The water quality of all the wells meets the requirements. The wells are checked, accepted and handed-over by the Ministry of Natural Resources and Environment (MONRE) to the localities for management, exploitation and utilization, details are as follows:

- Nghệ An Province: in 8 areas, 11/15 wells having the discharge over 0,5l/s, making up the total of 34,4l/s equal to 2.969m3/day.

Component 3 of the Project: “Investigation, assessment, planning and using of surface water and land in the coastal line; potential of groundwater in the coastal areas and islands”.

The Project was implemented by the three Divisions for Water Resources Planning and Investigation of the North, South and the Centre. The completed activities are: collecting data, analysis of remote sensing pictures, drawing hydro-geological map of 1:200.000 (5.945km2) and 1:50.000 (3.167km2); investigating and assessing on current status of groundwater exploitation; geophysical measurement, drilling, pumping tests, sampling and analysis of water samples.

Constructions are completed in 10 areas (including 3 islands), water was found in 36/38 wells. All of the wells are handed-over to the localities for management, exploitation and utilization

Project: “Investigation and assessment of groundwater in Neogene aquifer of Ha noi city”.

Objectives:

- Definition of geological and hydro-geological features of Neogene Aquifer;

- Assessment on the amount of water, zoning potential areas of the aquifer in the studied area;

The Project has been carried out by the Division for Water Resources Planning and Investigation for the North of Vietnam since 2007. 6/13 wells have been constructed so far. Details are as follows: LK1-N with the depth of 155m, at Đông Ngạc Commune, Từ Liêm District, Hà Nội, discharge of 16,44(l/s); LK3-N with the depth of 40m, at Long Biên district, Hà Nội, discharge of 16,40(l/s); LK6-N with the depth of 230m, at Ngũ Hiệp Commune, Thanh Trì district, Hà Nội, discharge of 5,50(l/s); LK8-N with the depth of 220m, at Lệ Chi Commune, Bắc Ninh, discharge of 20,06(l/s). The water quality is good. It is a potential aquifer that can supply water for industrial purposes in the studied area;

The high mountainous area of the West belongs to the massif of the Chay river’s upstream gathers with steep slopes, high passes, narrow valleys and stream beds; the climate of this area is divided into 2 seasons: rainy and dry. The low area of the Province includes hills, mountains, Lo river valleys and the town of Hà Giang.

Hà Giang was endowed with a number of high mountains with the highest peaks of Tây Côn Lĩnh (2419 m) and Kiều Liêu Ti (2402m).

Project on planning and investigation of water resources for the Central Region

mien_trungCentral Region of Vietnam or Central part (other former names are Trung phần (Vietnam Democratic Republic), Trung Kỳ (French colonized), and An Nam (by French) is one of the three main regions of Vietnam (Bắc Bộ, Trung Bộ, Nam Bộ) and located in the middle. Tây Nguyên is usually included in the Central Region. It is sometimes found a combined name of Miền Trung-Tây Nguyên. The name Trung Bộ has been used since Bao Dai King established regional administrative agency higher than provincial level in 1945, replacing the name Trung Kỳ, which lingered to the time of French colony. This name was used in official documents of Vietnam Democratic Republic. This name is also used by many people nowadays.

In addition, another name was known as Trung phần, which originated in 1049 when Head of Vietnam State Bảo Đại formulated administrative office with the same function of ministerial level in 1945. Then, the Vietnam Republic Government also used this name until its collapse in 1975. Decree No. 143-A/TTP by the President of Vietnam Republic dated on 23/10/1956 regulated to call Bắc Việt, Trung Việt, Nam Việt with the name Bắc Phần, Trung Phần, Nam Phần. Tây Nguyên was named Cao nguyên Trung phần by the Vietnam Republic (former name was Cao nguyên Miền Nam). According to the Decree No. 147-A/NV by the President of Vietnam Republic dated on 24/10/1956, Trung Phần included Cao nguyên Trung phần and Trung nguyên Trung phần.
