Bisschop, Femke (author)Mangrove forests are important (sub)tropical intertidal ecosystems providing coastal protection and other ecosystem services like carbon storage and biodiversity. In view of the loss of these forests many rehabilitation projects have started, but unfortunately these efforts often fail. A main cause for coastal erosion is a disrupted (fine)...master thesis 2023

van der Hagen, Joep (author)Due to accelerating climate change, which entails more extreme storm conditions and exponential sea level rise, the protective function of our dikes and levees is under growing pressure. The presence of so-called forelands (e.g., beach, mudflat, and tidal marsh) are promising Nature-based Solutions to reduce the probability of dike failure and...master thesis 2023

Melissaris, Themistoklis (author)Cavitation is the formation of vapor pockets in a liquid due to a pressure drop or an increase in speed. Cavitation nuisance can be disastrous for mechanical components, and therefore needs to be controlled from an early design stage. However, predicting cavitation dynamics using CFD (Computational Fluid Dynamics) and therefore the performance...doctoral thesis 2023

Konstadinou, M. (author), Herrier, G. (author), Stoutjesdijk, T. (author), Losma, F. (author), Zwanenburg, C. (author), Dobbe, R. (author)This study aimed to assess the suitability of lime treatment for use in dikes in the Netherlands. The effect of this technique on the behavior of a Dutch clay was addressed by comparing the detailed response of lime-treated and natural samples at different lime contents (1.25% and 2.25%) and curing periods. A series of laboratory tests...journal article 2023

Pol, J.C. (author), Kindermann, P.E. (author), van der Krogt, M.G. (author), van Bergeijk, Vera M. (author), Remmerswaal, G. (author), Kanning, W. (author), Jonkman, Sebastiaan N. (author), Kok, M. (author)Structural reliability analysis often considers failure mechanisms as correlated but non-interacting processes. Interacting failure mechanisms affect each others performance, and thereby the system reliability. We describe such interactions in the context of flood defenses, and analyze under which conditions such interactions have a large impact...journal article 2023

Zou, Yingxue (author), Xu, Haiqin (author), Xu, S. (author), Chen, Anqi (author), Wu, Shaopeng (author), Amirkhanian, Serji (author), Wan, Pei (author), Gao, Xiang (author)Moisture erosion is one of the key factors leading to asphalt pavement damage, and the erosion depth indicates the moisture damage level but it is usually neglected. In order to study the moisture erosion and the erosion depth, this study characterized the chemical structure, rheological property and adhesion property of asphalt at different...journal article 2023

(author), Wu, Shaopeng (author), Amirkhanian, Serji (author), Xu, Haiqin (author), Zhao, Zenggang (author)Layered double hydroxides (LDHs) can shield polymeric materials from UV light, which allows reducing material aging and erosion damage of bituminous pavement under physical and chemical action. In this study, the physicochemical properties, aging resistance, and erosion resistance to the aqueous solution of LDHs modified bitumen mastic (BM) were...journal article 2023

Alhaddad, S.M.S. (author), Helmons, R.L.J. (author)To date, hydraulic collection is the most widely considered technology in polymetallic-nodule mining, since there is no direct contact between hydraulic collectors and ocean floor. To construct a hydraulic collector that results in the least sediment disturbance, it is critical to develop an insightful understanding of the interaction between...journal article 2023

Alhaddad, S.M.S. (author), Weij, Dave (author), van Rhee, C. (author), Keetels, G.H. (author)As a result of the dilation of soil matrix, dense submarine sand slopes can temporarily be steeper than the natural angle of repose. These slopes gradually fail by the detachment of individual grains and intermittent collapses of small coherent sand wedges. The key question is whether steep disturbances in a submarine slope grow in size ...journal article 2023

Damastuti, Ekaningrum (author), van Wesenbeeck, B (author), Leemans, Rik (author), de Groot, Rudolf S. (author), Silvius, Marcel J. (author)Management and restoration of mangrove forests to protect coasts are promoted in many countries, including Indonesia. Indonesian mangrove forests are actively restored and managed by local communities for their ecosystem services, including coastal protection. Whether community-based mangrove management (CBMM) is effective is still debated....journal article 2023

Nijensteen, Ilse (author)The Catterline Bay, located in North East Scotland, is prone to erosion processes. Using Terrestrial Laser Scanning (TLS) two point clouds were obtained in 2019 and 2022 from this area of ca. 0.2 km<sup>2</sup>. Here, a methodology was proposed and tested to assess how erosion processes can be monitored from high resolution point clouds in small...master thesis 2022

Pol, J.C. (author)Structural flood protection systems such as levees are an important component in flood risk reduction strategies. Levees can fail through various failure mechanisms; this thesis focuses on the mechanism Backward Erosion Piping (BEP) which occurs when a sandy levee foundation is eroded by groundwater flow. To assess whether a levee's reliability...doctoral thesis 2022

Le Grand, Oscar (author)Sea level rise will increase the risk of flooding in coastal areas. This poses a risk to the coastal protection as well as rivers and lakes close to the coast. Solutions are needed to cope with this threat. The past decade, nature based solutions have gained significant interest. One of these solutions could be sandy foreshores. Due to the use...master thesis 2022

Jagarlapudi, Aravinda Virinchi (author)The Saturnian moon Titan has a methane-based hydrological cycle similar to the water cycle on earth. This includes lakes, fluvial drainage networks, clouds and has evidence for precipitation of methane rain. Here we explore the impact of rainfall on Titan based on an analogue laboratory approach. While the composition and structure of the Titan...master thesis 2022

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 Overeem, Jan (author)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...master thesis 2022

Heineke, Esther (author)Coastal protection is required to keep coastal areas protected during storm conditions. Coastal dunes are a natural defense against flooding and erosion from the sea against storms. Many insights have been obtained regarding the positive effects of coastal dune vegetation on dune formation and growth in the past. Several recent studies have...master thesis 2022

Boon, Casper (author)Wave overtopping, in which a wave washes over the crest of a dike and damages its inner slope, is one of the many mechanisms that is found to be responsible for dike failures. As these dikes are generally covered with grass, insight into the erosion resistance of these grass covers against wave overtopping is desired. To assess the performance...master thesis 2022
