Guidelines on monitoring and assessment of transboundary rivers

After a period four years, amendments and additions to the river Guidelines were necessaary, especially in view of the international strategic and scientific developments of the past few years. The Guidelines are based on the ecosystem approach in water management. Consequently, the Guidelines take into account the entire water system in the catchment area of a transboundary river, including the various components of the aquatic and riparian ecosystems it supports.
