Biohydrodynamics

Water movement affects marine organisms in various ways. Currents and waves set mechanical limits for growth and survival for fauna and flora. Flow may also facilitate biological processes, e.g. nutrient and food uptake, disposal of waste products, and dispersal of propagules. Recent research offers many examples of how studies of hydrodynamics are necessary for a correct understanding of a wide range of biological mechanisms, from the molecular to the ecosystem level. The term biohydrodynamics emphasizes the interdisciplinary approach necessary to understand how biological processes are affected, controlled or limited by hydrodynamics.

Industrial interest and regional effects
Västra Götalandsregionen is the most marine region in Sweden. Advanced knowledge is required for a better and sustainable utilisation of the marine resources. Local communities, regional authorities and industry are all potential stakeholders for knowledge that are developed within biohydro-dynamics. Examples are a better understanding for speed restrictions for big ships and high-speed vessels, and development of new low-toxic methods for protection against marine fouling on ships and other marine constructions.
