Morphodynamic modelling for the entire German Bight: an initial study on model sensitivity and uncertainty

Morphodynamic modelling of coastal seas and estuaries for large-scale and long-term applications is strongly affected by parameter sensitivity of process-based models. Moreover, the comparison of data-based methods with numerical model results is limited by uncertainties in measurements. These drawbacks can be partly overcome by a multi-model approach (MMA). In a case study to assess long-term sediment transport and morphodynamic processes for the German Bight, the AufMod research project applies two different methods for process-based modelling: UnTRIM-SediMorph and DELFT3D. Model sensitivity is illustrated in terms of different morphological changes for diverse porosity values. As a first step, discrepancies between individual methods are shown based on resulting sediment transport patterns

Modelling the Denmark Strait overflow during the last interglacial cycle : from regional dynamics to basin wide impacts

The Denmark Strait overflow is the major gateway for dense water from the Nordic Seas into the North Atlantic and thus it constitutes an important part of the thermohaline circulation under present-day climate conditions. This study focuses on the regional to basin wide dynamics of the Denmark Strait overflow for present-day and Last Glacial Maximum conditions. It contributes to the Research Unit Ocean Gateways located at the University of Kiel which addresses the question how ocean gateways might have affected climate in the past.The volume transport of the overflow is likely to be controlled by hydraulic constraints, thus the transport is set by the relative density contrast between the water masses north and south of the Denmark Strait and the height of dense water above sill level. By using high resolution numerical models it is investigated how the volume transport can be best described using existing hydraulic theories. Hydraulic constraints are shown to be valid over a wide parameter range which allows to transfer this theory to LGM conditions

Was bleibt vom Maastrichter Stabilitätsversprechen?

Im Verfassungsentwurf des Europäischen Konvents wird das Ziel der Preisstabilität und die Unabhängigkeit des Europäischen Systems der Zentralbanken (ESZB) schlechter abgesichert als im Maastrichter Vertrag und im geltenden EG Vertrag. Ansgar Belke, Frank Baumgärtner und Wim Kösters warnen vor den Folgen der Verletzungen der gegenwärtigen europäischen Geldverfassung. --
