B A C K G R O U N D The research project is focussed on the Thi Vai river basin and the Can Gio mangrove forest in South Vietnam. The selected project areas are situated in three provinces: Ho Chi Minh City, Dong Nai and Ba Ria-Vung Tau.
Development of a model-based water management system Sustainable improvement of the environmental and living conditions of the selected coastal zone in South Vietnam with focus on inland water quality and coastal protection Implementation and optimization of innovative technologies of industrial waste water treatment Close collaboration between Vietnamese and German scientific communities and companies
About the project (2012 – 2015) O V E R A L L
O B J E C T I V E
The overall objective of the research project is the development, supply and use of water and environmental technologies and service tools in the framework of a management system. The system will allow the users to sustainably improve the environmental and living conditions of the selected coastal zone in South Vietnam. The project takes into account the anthropogenic influences as well as the natural climate variability and the impact of future climate change on water quantities and water quality. In addition, the project aims to transfer the EWATEC-COAST concept to other regions.

With relevance to the water management of the region, the following results are expected from the subprojects: Forecast on climate change for the project areas Provision of a regional air pollution model Integrated model system for water balance, mass transport, surface flow, groundwater flow and water quality Bio-reactor model for mangroves at landscape scale with focus on the removal of pollutants in the water bodies Modeling of the coastal waters, determination of the loss potential due to onshore storm floods, risk analysis for the coastal zone Implementation and optimization of an experimental pilot plant for the purification of tannery wastewater Set-up of a model-based management system (planning tool) by integration of abovementioned components Forecast of the water quality effected by anthropogenic influences and climate change in the areas; development of solution concepts

S TA T U S O F W A TE R About 80 companies, mostly situated in industrial areas along the river, are discharging 34.000 m3 waste water per day without any treatment or with minor treatment. Due to the numerous discharges, the river has been considered ecologically dead since about 1995. The Vietnamese Government demands the ecological restoration of the Thi Vai river basin.
C A N G I O MA N G R O V E F O R E S T The Can Gio mangrove forest, adjacent to the Thi Vai river basin, covers about 760 km2. The mangrove forest was designated as a biosphere reserve in 2000. In recent years, the reserve was substantially damaged by erosion, sedimentation along the coastal region, fish farms, sewage and oil pollution mainly originating from inland waters.
SUBPROJECTS EWATEC-COAST consists of nine interacting subprojects ranging from meteorological investigations to coastal flood protection. Results are implemented into a water management system.
