In order to in detail be able to investigate and assess the implications of hydropower
development in an environmental context, equipment/infrastructure for measuring and
analysing in situ/changing/post-change situations is of vital importance. In detail, there is a
need for acquiring and updating infrastructure in relation to potential water temperature, water
quality, meteorological conditions, hydromorphological river dynamic change and dependent
river system parameters like discharge, water velocities , water level and particle movement in
three dimensions. Other vital needs in relation to ecological indicators of change include
beaver, otter and birds. In addition, CEDREN are working on greenhouse gas measurements
and analysis, a rapidly expanding top ic in relation to current and future hydropower
development in general, specifically related to hydropower reservoirs on a global scale. In
understanding the scope and range of this topic it is necessary to conduct effective
measurement campaigns, using u pdated infrastructure.
