Kalloe, S.A. (author), Hofland, Bas (author), van Wesenbeeck, B (author)Vegetation in front of levees, dikes and seawalls can decrease wave energy and therefore contribute to the safety against flooding. However, wave damping predictions by vegetation are still inaccurate due to measurement and modelling uncertainties. Many studies focused on finding reliable predictive tools using scaled flume tests with...journal article 2024

Speth, Florine (author)Coral reefs are considered to be a crucial ecosystem and form of natural coastal protection. They owe their effectiveness to their high structural complexity. This complexity, which positively influences aspects like species richness, coral recovery, live coral cover, and coastal protection, is often quantified using parameters such as porosity...master thesis 2023

Alferink, M. (author), Gijón Mancheño, A. (author), Suzuki, Tomohiro (author), Reniers, A.J.H.M. (author)The coastline of Demak, Indonesia, has been eroding during the<br/>last 15 years. Coastal retreat in Demak is caused by a combination<br/>of mangrove deforestation and local subsidence due to groundwater<br/>extraction in the nearby city of Semarang. To restore the lost mangrove<br/>forest, permeable dams, consisting of bamboo poles with a<br/...journal article 2023

Zhang, R. (author), Chen, Y. (author), Lei, Jiaxin (author), Zhou, Xin (author), Yao, P. (author), Stive, M.J.F. (author)Mangroves can function as a ‘bio-shield’ to protect coastal communities from harsh environments because of their strong ability to attenuate wave energy. However, as mangroves are usually oversimplified as rigid cylinders in antecedent studies, the effects of complex mangrove morphology on wave attenuation have not been well researched....journal article 2023

Marin-Diaz, Beatriz (author), van der Wal, Daphne (author), Kaptein, Leon (author), Martinez-Garcia, Pol (author), Lashley, Christopher H. (author), de Jong, Kornelis (author), Nieuwenhuis, Jan Willem (author), Govers, Laura L. (author), Olff, Han (author), Bouma, Tjeerd J. (author)Salt marshes fronting coastal structures, such as seawalls and dikes, may offer important ecosystem-based coastal defence by reducing the wave loading and run-up levels during storms. We question (i) how the long-term salt marsh development in the Dutch Wadden Sea relates to the tidal-flat foreshore bathymetry and (ii) how the wave run-up...journal article 2023

(author), Hofland, Bas (author)With the capacity to reduce wave energy and trap sediment, Scirpus mariqueter has become an important native species of annual grass for ecology restoration at the Yangtze Estuary in eastern China. Due to seasonal variances of biophysical characteristics, S. mariqueter usually bends and breaks in winter, resulting in flattened stems that may...journal article 2023

Valiya Valappil, S. (author), Goosen, J.F.L. (author), Aragon, A.M. (author)Ultrasonic flowmeters that use transit-time ultrasonic transducers face measurement errors due to 'crosstalk,' whereby the working signal travels through the pipe wall and couplings, interfering with the signal from the fluid. Although various procedures have been proposed to solve the issue of crosstalk, they're limited to low-frequency...journal article 2023

Gallardo Torres, Victor (author)Wave surfing is a water sport in which a surfer uses a board to ride a wave towards the shore. It is done in the coastal areas around the globe. Each surf spot has its own wave quality depending on the wave climate and the type of coast. Some spots have year-round perfect waves and other surf spots only work ’when the stars are aligned.’ The...student report 2022

van der Zanden, Joep (author), van der Hout, A.J. (author), Otto, William (author), Spaargaren, Floor (author), Walles, Brenda (author), de Wilde, Jaap (author)Floating breakwaters are moored structures that attenuate wave energy through a combination of reflection and dissipation. Studies into floating breakwaters have been generally restricted to optimising the attenuation performance. This study presents a novel floating breakwater type that was developed to have good attenuation performance while...journal article 2022

van Wijk, J. M. (author), de Hoog, E. (author), Talmon, A.M. (author), van Rhee, C. (author)The hydraulic transport of sediments in sediment–water multiphase mixtures is an important process in nature and many industrial applications. The flows are characterized by complex transient phenomena, in which the overall system scale and the particle scale are equally important. Experimental research into dense mixture flows is focused on...journal article 2022

van Dongen, Lotte (author)Because the demand for green energy increases rapidly, it is expected that solar and wind energy will dominate future power generation. New in this field is the development of offshore floating solar systems, consisting of multiple interconnected platforms that are covered with PV panels. Besides satisfying the demand for electricity, these...master thesis 2021

Sigel, Luis (author)An increasing amount of the worlds coastal regions suffer from structural erosion due to anthropogenic influences. A prime example for this phenomenon is the Oosterschelde, Netherlands, where the partial closure of an estuary lead to a decline of the local intertidal flats, threatening the valuable functions they provide as an ecosystem and for...master thesis 2021

Azevedo Vasconcelos, A.C. (author), Schott, D.L. (author), Aragon, A.M. (author), Jovanova, J. (author)This paper discusses an elastic metamaterial for filtering energy from certain frequencies of an incoming wave. The unit cell, which is composed by a single material, is built to obtain a local resonance band gap. Since Bloch-Floquet's periodic condition is enforced to the unit cell, the dynamic characteristics of the metamaterial is obtained...conference paper 2021

van der Velden, Marieke (author)The Engineering Office of the municipality of Amsterdam is developing six man-made islands in the IJmeer. One of the last islands will be Buiteneiland. The location and orientation of Buiteneiland is been agreed when IJburg was designed. The area of interest of this study is the land-water transition at the east side of the island. The IJmeer's...master thesis 2020

Ascencio Ascencio, Jaime (author)Climate change puts under pressure existing and future coastal interventions. Growing threats like sea-level rise and intensity of storms require solutions to be adaptable and resilient. Nature-based solutions have shown to tackle these challenges while providing social, environmental, and economic benefits. The role of vegetation in coastal...master thesis 2020

(author)Foreshores consisting of both bare tidal flats and vegetated salt marshes are found worldwide and they are well studied for their wave attenuating capacity. However, most studies only focus on the small scale: just some isolated locations in space and only up to several years in time. In order to stimulate the implementation of foreshores...journal article 2020
