Toe stability of rubble-mound breakwaters

This Master Thesis contains a study on the stability of the toe structure of rubble-mound breakwaters based on small scale model tests performed in the large wave flume of the Laboratory of Fluid Mechanics of the Faculty of Civil Engineering of Delft University of Technology. In this report the study of Gerding (1993) on the stability of toe...

B.O.O.S. (Bestuurder: Oogjes Open Systeem)

In slaap vallen in het verkeer is nog steeds een grote oorzaak van verkeersongevallen en leidt elk jaar nog tot veel slachtoffers.
