Ecomorphology Level F – Drop structures

To enable surface waters to be fully protected, their status must be known. The Modular Stepwise Procedure provides the framework for standardized investigation and assessment of surface waters. The procedure is modular in structure and comprises surveys of hydrology, watercourse structure (ecomorphology), water chemistry and ecotoxicology, and the communities of animals, plants and microorganisms (biology).The Ecomorphology module surveys the structural characteristics of the streams and rivers in regions as a whole, e.g. cantons, regions, municipalities) (Level F). The “Drop Structures” layer identifies artificial and natural disruptions to continuity according to their type (wood, rock, concrete and other).
