Abstract

There are four majour rivers in Danang city: Han river, Vu Gia river, Cude river and Phu Loc river, of which the Vu Gia and the Cude rivers provide water for daily needs, industry and agriculture of the whole city. They are both water supplies and the places receiving sewage from agricultural activities, cattle breeding, industrial use and municipal wastewater. There are complex socio-economic activities at the lower section of the Cude river. Survey results collected since 2005 shows that this is the major cause of the river water pollution. This paper assesses the water quality changes, analyses socio-economic activities at the lower section of the Cude river and then proposes effective management solutions.
