van Balen, Ivo (author)Following significant physical and economic damage associated with large tsunami disasters, this research assessed the efficacy of both nature-based and man-made tsunami mitigation measures. With an expected increase of the population living in tsunami-prone areas, it is critical to develop a better understanding of tsunami engineering. <br/><br...master thesis 2023

Brühl, M. (author), Prins, Peter J. (author), Ujvary, Sebastian (author), Barranco, Ignacio (author), Wahls, S. (author), Liu, Philip L.-F. (author)In this paper, we study the propagation of bores over a long distance. We employ experimental data as input for numerical simulations using COULWAVE. The experimental flume is extended numerically to an effective relative length of x/h=3000, which allows all far-field solitons to emerge from the undular bore in the simulation data. We apply the...journal article 2022

(author), Efendi, Joni (author), Elbanna, Ahmed E. (author), Dubernet, Pierpaolo (author), Abidin, Hasanuddin Z. (author)Hazardous tsunamis are known to be generated predominantly at subduction zones. However, the 2018 Mw 7.5 Palu (Indonesia) earthquake on a strike-slip fault generated a tsunami that devastated the city of Palu. The mechanism by which this tsunami originated from such an earthquake is being debated. Here we present near-field ground motion (GPS...journal article 2022

(author), Riva, R.E.M. (author)A devastating tsunami struck Palu Bay in the wake of the 28 September 2018 M<sub>w</sub> = 7.5 Palu earthquake (Sulawesi, Indonesia). With a predominantly strike-slip mechanism, the question remains whether this unexpected tsunami was generated by the earthquake itself, or rather by earthquake-induced landslides. In this study we examine the...journal article 2022

Roubos, Jochem (author), Glasbergen, Toni (author), Hofland, B. (author), Bricker, J.D. (author), Zijlema, M. (author), Esteban, Miguel (author), Tissier, M.F.S. (author)To calculate tsunami forces on coastal structures it is of great importance to determine the shape of the tsunami front reaching the coast. Based on literature reviews, analytical reasoning,video footage, and numerical modelling it is concluded that both the continental shelf slope and the bay geometry have a significant influence on the...journal article 2021

(author)Japan and the Netherlands have very different physical, historical and cultural contexts but they share a vulnerability to extreme flood related events and have, in both their (relatively) recent pasts, had to recover from such events: the floods of 1953 in the Netherlands or the tsunami that hit Japan’s east coast in 2011. This paper describes...journal article 2020

(author), Ishii, Hidenori (author), Hamano, Go (author), Takabatake, Tomoyuki (author), Shibayama, Tomoya (author)The accurate modelling of overtopping of coastal defences by tsunami waves is of vital importance for the formulation of disaster management strategies. To improve knowledge of this phenomena the authors conducted experiments on coastal structure overtopping using bores that were generated by a dam-break mechanism. Three types of structures...journal article 2020

Wüthrich, D. (author), Ylla Arbos, C. (author), Pfister, Michael (author), Schleiss, Anton J. (author)Tsunamis, impulse waves, and dam-break waves are rare but catastrophic events, associated with casualties and damage to infrastructures. An adequate description of these waves is vital to assure human safety and to generate resilient structures. Furthermore, a specific building geometry with openings, such as windows and doors, reduces wave...journal article 2020

Zou, P. (author), Bricker, J.D. (author), Uijttewaal, W.S.J. (author)A submerged floating tunnel (SFT) is a promising alternative to conventional bridges and tunnels, and can be potentially built in the Qiongzhou Strait in China. However, this area is under the threat of disasters including mega tsunamis and severe storm surges. To evaluate the hydrodynamic loads of the SFT in this hazardous zone subject to...journal article 2020

Nederlof, Ilse (author)In the face of climate change, urban stormwater management practices are subject to an uncertain context. More frequent and extreme rainfall events are expected in many urban areas. The extent how climate change will affect weather patterns is however uncertain. This challenges contemporary stormwater management practices. A post-disaster...master thesis 2019

Wellen, Fleur (author), Winkel, Sander (author), Vrinds, Thijs (author), van der Voort, Tjalie (author)In Chile, the Biobío river separates the cities of Concepción and San Pedro de la Paz. Bridges crossing the Biobío river ensure a fast and dependable connection, which contributes to the transport options in the region. With the Biobío region being the second largest contributor to the country's GDP, an unreliable transport network is highly...student report 2019

YASAKU, Toshiya (author)The conventional evacuation modelling assumes that that family members are to be together in the face of tsunamis and evacuate as a household or each person evacuate individually. This assumption, however, can cause an inaccurate prediction when taking family gathering behaviour into account, which was reported to have occurred during the 2011...master thesis 2019

Salet, Jesse (author)Recent major tsunami events generated by earthquakes inundated coastal cities and caused extreme destruction and loss of human lives. The collapse of coastal bridges due to tsunami wave impact represents a huge obstacle for rescue works. The need to understand tsunami effects and develop tsunami-resilient bridges became apparent in the aftermath...master thesis 2019

Roubos, Jochem (author)To calculate tsunami forces on coastal structures, the wave type in front of the coast is of great importance. Hence this paper aims to find ways to predict the type of tsunami wave breaking. Based on literature review, video footage, analytical reasoning and numerical modelling (SWASH) it can be concluded that both the continental shelf slope ...master thesis 2019
