The water quality monitoring network is a combined physico-chemical and biological network, the biological component focusing on macro-invertebrates. The sediment monitoring program produces biological data to assess sediment quality. Both monitoring programs aim to provide index values, applying a similar conceptual methodology based on the presence of macro-invertebrates. The biological data obtained from both m... Mehr ...
