The four case study areas (Helge å (SE), Selke (DE), Reda (PL) and Bērze (LV)) that are described in the tables on the following pages have been chosen based on four criteria:
- There are known water quality nutrient problems according to the Water Framework Directive,
- There are known flooding problems,
- There are other interests that may be included in dialogues about win-win solutions,
- There is abundant water flow and quality monitoring data that will facilitate hydrological scenario modeling with a reasonable accuracy.
