CASE STUDY: VU GIA –THU BON RIVER BASIN



Vu Gia –Thu Bon River Basin



Existing Condition

The Vu Gia- Thu Bon River Basin islocated in the central highlands and coastalregion of Vietnam and encompasses an

area of approximately 10,000 km2. Thebasin takes up roughly 90% of the QuangNam Province and also includes Da NangCity.

The Vu Gia-Thu Bon Basin accounts forapproximately 2.5% of the surface water inVietnam making it the 5th largest (involume) basin in the country.



Water Resources

• Highly variable water resources, during September toDecember of the wet season 70% runoff generated.

• February to March only 1% – 2% runoff generated.

• Rainfall varies spatially across the basin withapproximately 3000 – 4000 mm annually occurring inthe highlands and approximately 2000 annually onthe coast.

Surface Water



Water Resources

• Mostly used for domestic and small-scale productionneeds.

• Most wells are located in the coastal regions and

must be at least 15 – 30 m deep to obtain adequatequality water.

• Strong interaction between surface and groundwater.Sustainable groundwater yields are currently

unknown.

Groundwater



Population

• Population 1.4 million, 2.1% of the nationalpopulation.

• Density of the basin is 173 people/km2, which falls

below the national population density of 250people/km2.

• Population growth increase in line with the nationaltrends discussion, with little formal education.

•

This basin is prone to natural disasters, such asflooding and typhoons.•



Economy

• Based on agriculture, forestry, fishery, industry,mining, tourism, handicrafts and other services.

• Economic production in the basin is lower than that

of the national average, with the GDP per capita forDa Nang and Quang Nam, US$ 488 and US$ 230,while the national GDP per capita is US$ 2792.

• The low of economic status of the basin is due in partto an underdeveloped industrial sector and to poorinfrastucture and water shortages in the agriculturesector.



Biodiversity

• There is a little information on the habitat, migrationand flow requirements of the aquatic biodiversity thatunderpins the economy and livelihoods of number of

the residents in the basin.• A long the coast there are a number of important,

subsistence aquaculture farms. While aquaculture isincreasing within the basin, it still only occupies 0.1%area of the basin.

• Aquaculture may be introduced into hydropowerimpoundments to create jobs and new opportunities.



Governance

• Water management is still dominated by uni-disciplinary, single issue management approaches towater.

NOW WHAT?

Recommendation

1. Institutional and legal framework

Establishment of RBO that has legalmandate , functional management

board, technically and financially

equipped.

Capacity development



2. Formulation of Vu Gia-Thu Bon Basin
