摘要：Due to the subtropical climate the average annual precipitation in Vietnam is high. Nevertheless it is observed that groundwater levels in the capital Hanoi have decreased dramatically. As a consequence more and more settlements of buildings have been registered since the beginning of the new millennium. Reason for this tremendous impact is the increasing demand of areas and the extensive surface sealing in the course of the industrial development. This paper describes the “state of the art” and the development of sustainable solutions to maintain and even increase the declined groundwater levels in Hanoi.
