This disrupts the natural biogeochemical cycles of carbon, nutrients and metals and possibly will affect the whole catchment including downstream ecosystems such as wetlands, estuaries, deltas and adjacent sea areas.,Starting from changes that have already be documented, this article concentrates on the possible use of a „FerryBox“, that is an automated water quality measurement system on board a ship or on shore, to monitor the short and long term development of the quality of the river water in the backwater area and downstream of the dam. While there are already research programmes running to monitor the water quality of the river and the backwater area these programmes are limited to ship campaigns with sampling and laboratory analysis. The spatial and temporal resolution of such measurements is not sufficient for an overall assessment of the water quality and for prognoses in the context of anthropogenic and climate change.,Therefore, a concept of applying regular automated observations by a FerryBox is presented. It is shown that such systems are very well suited to give feedback for the assessment of measures to improve the water quality.
