Summary / ZusammenfassungMany coastal zones can suffer from the destructive impacts of tsunamis, storm surges and waves,particularly in densely populated river-mouth systems. Climate change and related sea-level rise(SLR) will strongly modify hydro-, sediment- and morphodynamics in coastal environments,forward saltwater intrusion into ground water and soils, and aggravate coastal hazards for manycities and societies. Two Junior Research Groups (JRG's) will be established under B5. B5(1) Sea-Level Rise and Physical-Morphological Changes in Coastal Seas will analyze the interaction of thethree land-sea, freshwater-saltwater, and water column-seafloor coupled interfaces. Combinedwater column and seafloor surveys at high-resolution timescales will integrate information onsediment dynamics and on migrating freshwater/saltwater transition zones. This constitutes a new,multifaceted approach referred to as Change Analysis. <strong>The</strong> JRG will be positioned at the interfacebetween marine sedimentology and marine geophysics and will bridge the gaps betweenmeasurements of present-day hydro- and sediment-dynamic processes and reconstructions fromthe sedimentary record. B5(2) From Coastal Hazards and Vulnerability to Risk Management willintegrate this information, along with data on the socio-economic and ecologic vulnerability on thelandward side, to establish a quantitative and model-based multihazard risk assessment tool. <strong>The</strong>primary objectives of the new JRG in B5(2) are to identify possible hotspots of risk in selectedregions, to quantify potential damage versus the economic benefits of response options and toimprove the feasibility of decision-making processes in risk mitigation in the presence ofconsiderable uncertainties.Küstenzonen, besonders die dicht besiedelten Flussmündungsgebiete, können durch den Einflussvon Tsunamis, Sturmfluten und Wellenangriff nachteilig beeinflusst werden.
