摘要

Research on the interaction between biota, sedimentation, erosion, and water flow plays an essential part in marine and freshwater ecology. Flow velocities and turbulence intensities have major effects on the sediment structure, erosion and sedimentation processes, which in turn have an effect on the local biota and morphodynamics. Both large scale and small scale hydrodynamic processes are therefore essential in shaping aquatic communities. Conversely, biological structures such as reefs, large aggregations of bivalves and seagrass beds may have a significant effect on the flow regime while sediment characteristics, such as erodability are influenced by biofilms.rnIn recent years, many advances have been made in this field. The EU-network BioFlow (BioFlow stands for Flume Facility Co-operation Network for Biological Benthic Boundary Layer research, and is an EU Concerted Action under Framework 5, contract number: EVR1-CT-2001-2008) aimed at bringing together the biologists, physicists and engineers who are all interested in this area bridging several different disciplines. This special section consists of papers presented at the fourth and last BioFlow workshop, held on Sylt in September 2005. This workshop focussed both on technological innovations in bio-fluid-dynamic research and on scaling of different processes.
