The Effect of Sand Nourishments on Foredune Sediment Volume: a Statistical Approach Nico Van Der Zwaag

The Dutch dune coast has to be maintained in order to keep the inland safe. This is done by adding sand to the system and increasing foredune sediment volume. These nourishments have significant effects on natural values in the dunes. This report further investigates the effect of nourishments on foredune sediment volume. New methods are developed to automate the use of coastal height data to calculate volume developments. The best number of trend lines is added to the developments, showing breaks in trend. These breaks in trend visualize the year of the nourishment. This research concludes with a case study to see whether nourishments upstream have effect on the volume development of the Groote Keeten location. There is no effect.
