BINH THUAN WATER SECTOR PROJECT IN VIETNAM:

  • Subproject name: DWS Domestic Water Supply System – North Ham Thuan district

  • Sub-project Ca Tot Reservoir – Bac Binh district

The area covered by this project is very important for the socio-economic development of the BinhThuan province that is a coastal province in the South Central Region special for the environmental status, therefore the priority assigned by the local public administration to this project.

The total land area of the province is 782,846 hectares with a population in 2015 of 1,157,322 people.

Hydrological characteristics

Binh Thuan doesn’t have large rivers only rather medium sized rivers (catchments’ areas from 100 – 10,000 km²) and rather small rivers (catchment’s acreage less than 100 km²). In the province there are in total 34 medium sized rivers, among them there are 3 rivers with catchment’s acreage over 1,000 km² (Luy River, La Nga River and Cai River-PhanThiet) and the remaining are small.

The main characteristic of the stream rivers of BinhThuan province is that they have short and steep slope. Due to the topographical characteristic of BinhThuan province, the river flows through various rainfall zones, so that the flow regime is also varied. Even along the same river their hydrological and hydraulic characteristics vary depending upon the zones crossed.
