Sensitivity analysis of single storm surges in the Jade-Weser Estuary
Coastal engineering is tasked with designing, constructing and maintaining hydraulic works in the coastal zone. Coastal dikes form a first hard line of defense against impend- ing storm surges, developed waterways ensure safe navigation and developed terminals facilitate maritime trade and are classified as critical coastal infrastructure depending on their individual turnover and criticality. European Windstorms, intrinsic to Europe, impact the German Bight ten times a year on average, inducing storm surges, eroding coastline stretches and obstructing navigation due to agitated sea states causing large monetary losses, endangering livelihoods and ne- cessitating ensuing repairs. These extra-tropical cyclones develop on the Atlantic Ocean and follow a westward storm trajectory through the North Sea. The German Bight, with its relatively shallow water depth and intricate coastline is located at the impact end of these storm trajectories. Due to the geographic nature this coastline exerts a funneling effect on storm systems with northern or western incident angles. Ubiquitous environ- mental changes impact atmospheric and hydrospheric processes, which control the for- mation and evolution of extreme system states such as storm surges. Consequently, the assessment of individual coastal key drivers is an integral part of coastal engineering and research investigating impacts on critical coastal infrastructure and coasts against the background of environmental change. In this thesis, potential impacts stemming from changes in sea level, estuarine discharge, sea state and aeolian quantities as well as sediment transport, are investigated for the Jade-Weser estuary. Identified changes are simulated employing a numerical open source software suite and evaluated for the transshipment complex Wilhelmshaven lining the Inner Jade, comprising several critical terminals. A comprehensive model quality assess- ment is carried out and demonstrates the well-suited character of the model to reproduce the complex hydrodynamics, sea ...
