 The impacts of the regulated rivers system will vary very much across the regulated system, and the mitigating measures that must be put in place will depend on how the hydrology of the rivers stretches under consideration are affected. As such, a clear understanding of which parts of the system that get dramatically reduced flows (bypass sections), which parts that experience a change in seasonality of the flow, and which parts that possibly experience higher flows (in the case of water transfer), and variants of these, must be thoroughly assessed. Some areas downstream the outlet of a power plants might be exposed to rapid and frequent changes in flow due to hydro-peaking operations, which call for another set of mitigating measures. In a process of finding the best single or combination of measures, an understand of the changes in flow introduced by the hydropower regulation is hence prerequisite.
-In the following, a set of traditional, new and innovative measures to improve the habitat and flow conditions in rivers affected by hydropower regulations are described. In the last part of each section, examples of successful implementation of measures are presented. It should be underlined that habitat and flow are not independent of each other, as for instance measures aimed at improving the flow conditions also affect the habitat (e.g. water depth and velocities), and also migration and possibly [[Sediment measures|sediment connectivity]]. As such, one measure can directly, or indirectly, improve the status of one or more of the defined problem types.

 The measures in the following sub-sections are presented separately. In a real situation, a combination of measures would be most cost-efficient. Sometimes one specific measure would have only a limited effect unless another measure is put in place at the same time, i.e. a set of measures being dependent on each other.
