Project Overview

This page gives an overview of interesting research projects for the different lab facilities over the past years.

Open filters on slope under wave loading

2021

Facility: Wave flume

Researchers: Tim Luijten (MSc)

Description: The stability of under layers of a rock protection on a slope is tested under irregular wave loading. The characteristics of the under layer material, like size and grading width, are varied.

Reversed open sand-gravel filter with surcharge

2021

Facility: Tilting flume

Researchers: Maarten Buitelaar

Description: The goal of this study is to characterise the effect of bottom roughness on the wave front celerity, water depth and wave front profile of dam-break waves in a channel with initially dry and wet beds. Artificially and naturally created roughness plates are placed in the flume just after a gate mechanism.

 

 

Reversed open sand-gravel filter with surcharge

2021

Facility: Dedicated reversed filter facility in Stevin 2 lab.

Researchers: Robert Lengkeek (MSc)

Description: The stability of an open filter with sand above gravel, under small hydraulic loading by porous flows is studies. Specifically the influence of a large surcharge, that mimics the weight of the sand layer above the interface.

 

Marker Wadden Fieldwork

2021

Facility: Field work at Marker Wadden

Researchers:  Anne Ton (PhD) plus MSc students

Description: Study of the nearshore hydrodynamics (ADV, OSSI) and topographical measurements techniques (drone, stereovision, GPS) at the sandy shores of the Marker Wadden, where unlike normal beaches no tides or swell waves occur.

 

 

Texel Fieldwork

2021

Facility: Field work

Researchers: Marlies van der Lugt (PhD)

Description: Field measurements of hydrodynamics and bedload transport were conducted at the Prins Hendrikzanddijk on Texel, a retrofit estuarine beach in close proximity of a tidal channel, to investigate beach profile dynamics under mixed-energy conditions.

 

Bresdefender

2021

Facility: Flood Proof Holland

Researchers: Danny Janssen (PhD)

Description: At Flood Proof Holland an emergency measure to close dike breaches is tested at mid scale.

 

Flow field around submerged groins

2020 - 2021

Facility: 5-m flume

Researchers: Johan Harms (MSc research) 

Description: Detailed tests have been made on the flow field around submerged river groins. Experiments were done with an array electromagnetic flow sensors and surface floaters (PTV).

 

Cauchy-scaled model of willow trees

2021

Facility: Wave flume
Researchers: Su Kalloe (PhD research)
Description: The wave damping performance of a managed willow forest (griend) is measured, and scale effects are determined. The forest is a replica of the forest that was tested at real scale in the Delta Flume, including scaled flexibility of the branches.

Extreme waves due to abrupt depth transitions

2021

Facility: Wave flume
Researchers: Madelief Doeleman (MSc)
Description: An experimental study into the occurrence of extreme waves due to abrupt depth transitions at future offshore wind farm locations along the Dutch coast. (see link)

LED-based PIV measurement of confined wave impacts

2019 - 2020

Facility: Wave flume
Researchers: Wout Bakker & Ermano de Almeida
Description: A large-scale LED-based light sheet was developed by Wout. This was used for PIV measurements of confined wave impacts in the DynaHicS project by Ermano.

Recurves on seawalls

August 2020

Facility: Wave flume
Researchers: Alessandro Antonini (Assistant Professor) and
Dimitris Dermentzoglou (Master student)
Description: The influence of a recurve parapet on the forces on, and the wave overtopping a vertical seawall is measured.  

Dune Erosion at the Sand Engine

August 2020

Facility: Field work (drone)
Researcher: Jasper Scheijmans (Master Thesis)
Description: A 40 ft container has been placed on the beach, in which artificial dunes are made to investigate coastal dune erosion speeds for different dune forms

Sediment-laden flows triggered by water jets

June 2020

Facility: Breaching flume
Researcher: Patricia Buffon (PhD student)
Description: Patricia is investigating the formation of turbidity currents by an impinging 2D water jet. If you like to know more about this research please contact P.Buffon@tudelft.nl.

BresDefender: Effect on the phreatic surface of a dike

June 2020

Facility: Sediment flume
Researcher: Danny Janssen (PhD student)
Description:
Effect of an impermeable plate on the phreatic surface level in a dike.

Scour in front of a breakwater

May 2020

Facility: Wave flume
Researcher: Casper Jantzen (Master Thesis)
Description: 
The goal of this study is to characterise the maximum scour and scour over time in front of the toe of a rubble mound structure and how this is influenced by the bottom protection in front of the structure.

Coral Wave Damping

March 2020

Facility: Wave flume
Researcher: Paul van Wiechen (Master Thesis)

Flow structures around the inlet sill of longitudinal training walls

March 2020

Facility: 3-m shallow flow flume
Researcher: Annemarie van Os (Master Thesis)
Description: Research about the flow structures around the inlet of longitudinal training walls for the development of a parameterisation of sediment transport over the sill.
