The maximum influence of wind on wave overtopping at mildly sloping dikes with a crest element

Due to the rising sea level in combination with land subsidence there is a need to reinforce the dikes. The use of a crest element to increase the height of the dike is an effective and relatively cheap way to reinforce the dikes (Hogeveen, 2021). When a crest element is used, the jet generated by wave breaking on the dike slope impacts on the...

Coastal Erosion at Spratt Bight Beach, San Andrés: A study on its cause and the applicability of the Building with Nature approach

San Andrés is a Colombian-Caribbean Island located 800 km from the Colombian coast. On its Eastern side there is a barrier reef formation protecting the island from offshore incident waves. Due to the protected environment created by the coral reef, sandy beaches can be formed on the East side of the island. <br/>During normal conditions, waves...

A case study of the new breakwater of the Port of Genova: Comparing the PIANC design method with the new EUROCODE

Breakwaters used to protect harbours and coastal areas worldwide are one of the most common coastal structures. The complexity of the physical processes associated with the design has led to the development of many empirical formulas while a standardized method for the selection of breakwaters’ design parameters in the EU does not yet exist. The...

Venice and the Lagoon: Two new visions

What long ago started as a small fishing village, seeking refuge from the Romans, slowly evolved into the city of Venice that we know today. With its unique location came unique problems, most of which were related to the interplay between Venice and its lagoon. By severe measures in the past it has continued to withstand the test of time. <br/...

Fieldwork Hydraulic Engineering: Asparuhovo Beach

Fieldwork Hydraulic Engineering’ is a course given at Delft University of Technology for the MSc Hydraulic Engineering. In collaboration with local experts Boyan Savov and Traian Marin, a team of 8 students guided by Mark Voorendt was sent to investigate the local conditions at Asparuhovo beach in Varna, Bulgaria, for purely educational purposes...

Puerto San Vicente, Chile: Evaluation of a Port Expansion

This report is written with the aim to evaluate a possible port expansion in the port of San Vicente, Chile. In order to achieve this a thorough analysis on the port operations, hydrodynamical analysis using Delft3D and a bottleneck analysis on the infrastructure have been executed. A preliminary design for the port expansion is created. This...

Wave Climate and Coastline Response of the Dutch Coast: Investigating the effect of large-scale offshore wind farm developments in the North Sea

To counteract the effect of climate change, a global agreement was put into force in 2016, aiming to limit the increase in average global warming and reduce greenhouse gas emissions. In that respect, European countries are investing in cleaner sources of energy and predominantly offshore wind, which has seen a rapid growth over the last years....

The determination of the feasibility of a 'Sand Breakwater' on the Nigerian coastline at Badagry

The coastal waters of Nigeria are a difficult environment to build structures to control the local morphology and hydrodynamic conditions to ones desire. This difficulty is a consequence of the persistent high-energy swell wave climate and Longshore Sediment Transport (LST) in the order of one million cubic metres per<br/>year. Besides these...

On the maintenance of the adjacent coast by sediment transported from recurring beach nourishments: A case study for the Holland coast

Since 1990, the Dutch coastline is maintained within the ‘Dynamic Preservation’ program, according to which the coastline is maintained seawards from a reference line, mainly by applying nourishments. Research into the maintenance of the Dutch coast is continuous and causes the content of the coastline preservation program to change constantly...

Wavelet analysis in the field of coastal engineering: Applications in time-series analysis

Time-frequency analysis and digital signal processing are important tools in the field of coastal engineering. Both can be done using techniques like Fourier or wavelet analysis, however, analysts from this field experience a threshold to use wavelet analysis instead of their current methods, often Fourier-based. This is due to the lack of...

Bathymetry Mapping using Drone Imagery

As extensive efforts from consumer drone manufacturers resulted in inexpensive aircrafts that can capture high quality video imagery, drones are increasingly considered to be beneficial for scientific purposes. In the recent past, video imagery has been used to analyze waves in terms of several hydrodynamic parameters and to indicate matching...

Fieldwork Coastal Enginering 2016

Since 2003 there is a cooperation between the Hydraulic Engineering department of Delft University of Technology and Bulgarian universities. The cooperation focusses on exchange of knowledge and the development of the coast in the area of Varna. Dutch and Bulgarian students get the possibility to gain experience in data collecting, processing...

Fieldwork Coastal Engineering 2015

The cooperation focusses on exchange of knowledge and the development of the coast in the area of Varna. Dutch and Bulgarian students get the possibility to gain experience in data collecting, processing...

Sustainable long term coastal protection and development based on sand nourishments

The study presents an assessment of sustainable practices for applying sand nourishments aiming long term coastal protection and development. Such concepts are applied in three study cases: Sylt (Germany), S'Abanell (Spain) and Ghanaian coast.

Morphological Impact of Coastal Structures

In many coastal engineering problems the application of coastal structures to resolve these problems seems to be a proper solution. In a lot of cases, however, the implementation of coastal structures does not lead to the expected situation. Erosion management operations may have unwanted impacts on a coastal system. Decisions on the most...

Evolution of beach profiles under random waves

Cross-shore sediment transport is an important phenomenon in coastal engineering, which mainly accounts for the short-term changes in the coastline. To study on- and offshore transport the evolution of the beach profile is considered. For investigation of the beach profile small-scale physical models are often used. A problem in using a physical...
