The importance of heterogenous shoreline habitats for ecosystem functions in regulated rivers

Carbon and nutrient cycles are highly dependent on the physical habitat heterogeneity and retention capacity within the riverine landscape. Functioning rivers need bioactive zones at all water levels for long-term stability. While during high water levels water bodies in the floodplain are important retention zones, shoreline structures within the main channel are considered key sites during low water situations. An understanding of the relationship between the function and design of artificial shoreline habitats are required for ecologically orientated planning and management of large rivers.
