This document describes a study into the influence of alongshore bathymetric variability on currents which form a risk to bathers. Changes to coastal zone management along the Delfland Coast have given rise to questions on the influence of alongshore bathymetric variability on bather risk. Extensive measurement data is available from two...

Shore-parallel submerged breakwaters (SBWs) appear as an attractive form of coastal protection. Compared to their emergent counterpart there is no impact on the beach amenity and aesthetics. In addition, there is a possibility for recreational purposes. However, the actual application of SBWs is often discouraged because the complexity of the...

Schlooz, G. (author)
This study investigates the hydrodynamics at a convex coastline. The Sand Engine, a man made peninsula in the Netherlands, is used as a case scenario. It is hypothesized that a rip current can develop under certain wave conditions due to the change in coastline orientation. The main goal of this research is to obtain a better understanding of...

Rip currents are seaward directed flows of water that traverse the surf zone, and in many cases pose potentially dangerous conditions for swimmers and beach users. The present study is carried out focusing on Perranporth beach, UK, which is known to present quite strong rip current events that have been the culprits of large numbers of incidents...

Rip currents are narrow, seaward directed flows in the surf zone that can pose a serious threat to swimmers. This issue has received attention particularly on swell dominated coasts (such as the US, Australia, France and UK) where numerous field experiments have been undertaken. However, the threat of rip currents is less recognised on wind-sea...

Jacobs, R.P.M. (author)
The nearshore zone is an active zone that can be quite inhospitable to humans due to violent wave breaking and strong rip currents. Rip currents are shore normal jet-like currents that typically extend from near the shoreline out past the line of breaking waves. Observations have concluded that a rip current system generally consists of 4 parts....

Poort, M.C.L. (author)
Detailed laboratory measurements of the wave and current field induced by bi-chromatic waves incident on an artificial surfing reef are presented. Strong wave focussing occurs on the surfing reef. Both PTV and in-situ measurements are reported that show the presence of a strong rip current flowing oblique off-shore. Observed water level set-up...

Vissser, R. (author)
The shoreline develops on several time scales. At some places along the coast the amount of sand in a cross-section decreases continuously and the shoreline shifts landward. This phenomenon is called structural erosion and is often caused by an increasing longshore sediment transport along the coast. When it is necessary to protect the coast, e...

Van Noort, J.C. (author)
Rip currents are narrow and intense, offshore directed flows in the nearshore zone. A rip current is able to transport a considerable amount of water and sediment seaward and may dominate the morphological exchange between surfzone and the offshore. Rip currents are often located nearby lateral boundaries that obstruct the longshore current, but...

This paper describes efficiency of the rip current barriers against the harbour shoaling. For investigation physical model was used. First wave basin geometry and external water supply was optimized in order to obtain a uniform longshore current along the coast. Then current pattern in 2 conditions -after construction of the breakwater and after...
