Abstract
Twenty-one watersheds were characterized and ranked on the basis of two multiple indicator systems, level 1 (least expensive) and level 2 (expensive). Furthermore, level 3 indicators are defined which need investigations in the field and are pretty expensive and only six watersheds are characterized.
Composite indicators are defined on the basis of level 1 indicators, called LSI, and level 2 indicators, called SWR. LSI and SWR are thought of as two different means to rank the watersheds with respect to the environmental health. The indicators on the three levels are considered as proxies to describe the abstract and not measurable concept of “environmental health.”
