Nearshore waves and related wave overtopping in complex estuaries

This dissertation focuses on the Eems-Dollard estuary in the north of the Netherlands and contributes to the MVED (’Meerjarige Veldmetingen Eems-Dollard’) field measurement project in the area. The Eems-Dollard estuary is part of the Wadden Sea, a shallow shelf sea with barrier islands, deep tidal channels, shallow tidal flats and wetlands. The...

Field Measurements of Very Oblique Wave Run-up and Overtopping with Laser Scanners

Oosterlo et al. (2019) developed a system using two terrestrial laser scanners, which can measure run-up heights, depths and velocities of waves on a dike in field situations. The system has now been placed next to two overtopping tanks on a dike in the Eems-Dollard estuary in the Netherlands to measure during actual severe winter storms. The...

Measuring (Oblique) Wave Run-Up and Overtopping with Laser Scanners

Wave overtopping is commonly measured using overtopping tanks. In this paper, an alternative system is developed by using two laser scanners. It measures wave run-up, as well as layer thicknesses and front velocities, both during normally and obliquely incident waves on a dike in the field. The paper considers the first field validation tests...

Analyses grass erosion in wave run-up and wave overtopping conditions

Within the framework of WTI, Research and Development of Flood Defence Assessment Tools (Wettelijk Toetsinstrumentarium), which is called in Dutch: WTI-2017 "Onderzoek en ontwikkeling landelijk toetsinstrumentarium", research was carried out to develop an erosion model for grass in the wave run-up zone consistent with the current model in use...

The wave run-up simulator: Idea, necessity, theoretical background and design

The idea of the Wave Run-up Simulator is based on the experiences with the Wave Overtopping Simulator. It is possible to simulate wave tongues overtopping a dike crest in reality. It must also be possible to simulate waves in the run-up and run-down zone of the seaward slope. This is the zone after waves have broken and when they rush-up the...

Golfoploop op stortsteengolfbrekers: Wave run-up on rubble mound breakwaters

Study on wave runup on a permeable rubble mound breakwater with antifer cubes as armour unit. Comparison of literature data with prototype measurement on the Zeebrugge breakwater and with data in laboratory experiments on different scales. Relation between wave runup and the pattern of the cubes. Some influence of the width of the spectrum was...

Technical report wave run-up and wave overtopping at dikes

This report is from Dutch origin and is a translation into English. In the Netherlands it is used as a guideline for safety assessment and design of dikes. Assessment of the required dike heights for wave run-up and wave overtopping is important in the Netherlands and has a long history. Some parts of this report, therefore, refer tot typical...

Wave overtopping of seawalls, design and assessment manual

This manual draws together and summarises previous research into the overtopping performance of seawalls. Data is re-analysed to provide a set of consistent design techniques, representing the most reliable approach to the assessment of seawall overtopping by wave action. The manual consists of five principal sections. Following introductory...

Effects of Slope Roughness on Wave Run-up on Composite Slopes

A comprehensive study of the wave run-up phenomena on single and composite slopes was conducted in order to determine the effects of slope roughness on regular and irregular wave run-up on composite sections, to determine the effects of slope roughness on the velocity distribution in the uprush zone, to investigate the energy loss in the uprush...
