Coast and Society
The coastal zone is the area where geosphere, hydrosphere, atmosphere, ecosphere and anthroposphere meet. Since prehistoric times the coast has provided people with habitat, food, trade ways, and facilitated socio-economic networking. However, coasts are also recognized as areas that are threatened, where rising sea-level, floods, storms, tsunamis, erosion and silting endanger livelihoods. These threats have become even more visible in recent times in the face of climate change and related oceanographic processes. A current need is development of models that demonstrate coastal processes along open coasts and in marginal seas, but also for estuaries and deltas at the mouth of river systems. Such models need to describe processes of hydro- and sediment-dynamics, sea-level change and coastal morphodynamics, dynamics of river mouth systems, and natural environmental processes vs. anthropogenic impacts. Model-based future projections can help to improve management of the coastal zone, including development of hazard warning systems, planning of construction and coastal protection, as well as promoting coastal zone sustainably, and mitigating the threats of coastal hazards. Geologists, oceanographers, engineers, modelers and socio-economists are invited to discuss questions of advanced modeling of coastal processes. One of the challenging requirements is to harmonize the model scales of engineering and natural processes in terms of space and time.
