On the anatomy of nearshore sandbars: A systematic exposition of inter-annual sandbar dynamics

Nearshore sandbars have a lifetime of many years, during which they exhibit cyclic, offshore directed behaviour with strong alongshore coherence. A bar is generated near the shoreline and grows in height and width while migrating offshore, before finally decaying at the seaward limit of the surf zone. It may take 10 to 15 years for a bar to...

On the Intersite Variability in Inter-Annual Nearshore Sandbar Cycles

Inter-annual bar dynamics may vary considerably across sites with very similar environmental settings. In particular, the variability of the bar cycle return period (Tr) may differ by a factor of 3 to 4. To date, data studies are only partially successful in explaining differences in Tr, establishing at best weak correlations to local...

De ontwikkeling van de onderwatersuppleties Ter Heijde, Noordwijk en Katwijk

Op 11 augustus 2006 heeft RIKZ aan de combinatie Witteveen+Bos / Koster Engineering opdracht verleend tot het uitvoeren van een evaluatie voor de onderwatersuppleties bij Ter Heijde, Noordwijk en Katwijk. De studie is begeleid door de heren AC. de Kruif, R. Spanhoff (RIKZ) en AJ.F. van der Spek (TNO). De evaluatie heeft uit de volgende...
