Project: Application of a methodology for assessment of sediments in navigable watercourses (partim : Biological Assessment). CAMPAIGN I.

01-APR-99 – 30-SEP-99

This is the first campaign of a bipartite project with the object to validate the methodology, developed by AMINAL/AWZ for the assessment of sediments in watercourses. For this the biological sediment quality of 90 samples, taken all over Flanders (Belgium), is examined. The assessment is based on the calculation of the Biotic Sediment Index (BSI) and the percentage of mentum deformations of Chironomid larvae. The usefulness of this methodology for the assessment of navigable watercourse sediments will also be tested.
