The Danish report is one of seven national reports presenting the results from each individual living laboratory. The Danish living laboratory Skodbjerge is located on the Danish North Sea Coast. The results will be compiled into a joint co-analysis providing for comparing nourishment performance and generating a better understanding of the factors that determine nourishment evolution. The Skodbjerge analysis focus on the nourishment performed in 2011, but the effects of other nourishments, especially the one performed in 2010 at Skodbjerge have to be taken into account because of the temporal scale of nourishment effects.
The Skodbjerge analysis aimes to answer the following questions regarding to the nourishment:
- What was the lifetime of the 2011 shoreface nourishment?
- How did the 2011 nourishment redistribute along and cross-shore?
- How did the 2011 shoreface nourishment influence the dry part of the coastal profile, especially the safety level?
- How is the nourishment decay correlated with the hydrodynamic forcing?
The living laboratory Skodbjerge is located on the Danish North Sea Coast, where the Danish Coastal Authority is executive in performing coastal protection.
The Danish North Sea Coast is a micro tidal wave dominated sandy coast. The coast is highly dynamic and the morphology changes responding and adjusting to the predominating climate conditions. Large alongshore variations in the coastline have been documented and indentations, which migrate as the bar system migrates alongshore in the sediment transport direction, which is southbound. These coastline indentations, which are characterized by a narrowing of the beach, mark potential erosional hotspot. The number of bars, their size and position in the offshore direction change rapidly, especially during storms.
