Building with Nature

New analysis on nourishment performance in Denmark

21 December 2018 - Published by Eric Boessenkool
One of the benefits of nourishments as a means of coastal protection is the fact that they blend into the natural environment. In turn, this means that the effects are difficult to untangle from the natural variation of the coastal system. The Danish Coastal Authority made an analysis on nourishment performance at the Danish living laboratory at Skodbjerge.

The analysis was done to identify the effects of shoreface nourishment by taking the autonomous behaviour of the system into account. This has proven important since in depth knowledge of the system is required in order to put the nourishment effects into perspective. And thereby reveal which effects are of such a magnitude that they cannot be ascribed to the natural variations and vice versa.

Investigation of 2011 nourishment
In this study, the evolution of the 2011 nourishment has been investigated in depth. In order to do this, the nourishment in 2010 has been taken into account to determine if the observed evolution was influenced by this prior nourishment. Furthermore, the 2010 nourishment functions as a basis for comparison and evaluation of the 2011 nourishment design.

Joint co-analysis
This analysis report is one of 7 national reports presenting the results from each individual living laboratory in the Building with Nature project. 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.
