Overes, P.H.P. (author), Borsje, B. W. (author), Luijendijk, Arjen (author), Hulscher, S. J.M.H. (author)Sand waves are found on shallow, sandy seabeds throughout the world and their dynamics may pose an imminent threat to offshore construction. Therefore, there is a pressing need to understand bed level dynamics in sand wave areas. These bed level dynamics lead to variations in sand wave shape and migration rate over time. However, these...journal article 2024

Wu, Guofeng (author), Liu, Qing (author), Xu, H. (author), Wang, Jun (author)Low-lying coastal areas are threatened worldwide by compound flooding effects, including sea-level rise (SLR), frequent tropical cyclones (TCs), and accelerated land subsidence (LS). Compound flooding results in a negative effect, creating challenges for decision-making and coastal management for sustainable urban development. To comprehend...journal article 2024

Nederhoff, C.M. (author), Leijnse, Tim W.B. (author), Parker, Kai (author), Thomas, Jennifer (author), O’Neill, Andrea (author), van Ormondt, Maarten (author), McCall, Robert (author), Erikson, Li (author), Barnard, Patrick L. (author)Subtropical coastlines are impacted by both tropical and extratropical cyclones. While both may lead to substantial damage to coastal communities, it is difficult to determine the contribution of tropical cyclones to coastal flooding relative to that of extratropical cyclones. We conduct a large-scale flood hazard and impact assessment across...journal article 2024

de Fockert, Anton (author), Bijlsma, Arnout C. (author), O'Mahoney, Tom S.D. (author), Verbruggen, Wilbert (author), Scheijgrond, Peter C. (author), Wang, Zhengbing (author)Hydraulic structures can be a promising place for tidal energy extraction due to the high flow velocities, easy access to the power grid and easy access for maintenance. However, quantification of the impacts of a tidal power plant in a hydraulic structure is not straight forward. In 2015 a pilot plant consisting of an array of five Tocardo...journal article 2023

(author), Apecechea, Maialen Irazoqui (author), Mengel, Matthias (author), Verlaan, M. (author)In the coming decades, coastal flooding will become more frequent due to sea-level rise and potential changes in storms. To produce global storm surge projections from 1950 to 2050, we force the Global Tide and Surge Model with a ∼25-km resolution climate model ensemble from the Coupled Model Intercomparison Project Phase 6 High Resolution...journal article 2023

Hooimeijer, F.L. (author), Bricker, J.D. (author), Ke, Q. (author), Bortolotti, A. (author), van der Heuvel, Jasper (author), Diaz, Andres (author)Mean sea level rise (SLR) could increase up to 2m by 2100, which would see damage caused by coastal flooding in Europe increase from €1.25bn per annum currently to €961bn in just over 80 years. Urban areas situated along the North Sea coastline are particularly vulnerable to extreme sea level rise (a combination of SLR, tide and storm surges)....journal article 2022

Yu, M. (author), Liu, X. (author), Wood, Paul (author), Wei, Li (author), Wang, Guoqing (author), Zhang, Jianyun (author), Li, Qiongfang (author)Due to an intensification of anthropogenic activities and climate change in recent decades, the hydrological connections and relationships between rivers and lakes have been significantly modified globally.

(author)Flood simulations are important for flood (fatality) risk assessment. This article provides insight into the sensitivity of flood fatality risks to the model resolution of flood simulations and to several uncertain parameters in the loss of life model used. A case study is conducted for river flooding in a polder in the Netherlands (the...journal article 2021

(author)Shallow tropical bays in the Caribbean, like Orient Bay and Galion Bay in Saint Martin, are often sheltered by coral reefs. In the relatively calm environment behind the reefs, seagrass meadows grow. Together, these ecosystems provide valuable ecosystem services like coastal protection, biodiversity hotspots, nursery grounds for animals and...journal article 2020

Storms, J.E.A. (author), Beylich, Achim A. (author), Hansen, Louise (author), Waldmann, Nicolas (author)This paper reconstructs the sedimentation volumes and patterns, suspended sediment yields, wind‐induced circulation patterns and sediment trapping efficiency of Lake Strynevatnet, western Norway as an integrated source to sink system. The lake became deglaciated ca 11 ky cal bp, with glacio‐isostatic uplift isolating the basin from the nearby...journal article 2020

Hassaballah, K.E.A. (author), Abbas Mohamedali, Y. (author), Omer, Amgad (author), Uhlenbrook, S. (author)Understanding the spatiotemporal dynamics of surface water in varied, remote and inaccessible isolated floodplain lakes is difficult. Seasonal inundation patterns of these isolated lakes can be misestimated in a hydrodynamic model due to the short time of connectivity. The seasonal and annual variability of the Dinder River flow has great...journal article 2020

van Rooijen, Erik (author), Mosselman, E. (author), Sloff, C.J. (author), Uijttewaal, W.S.J. (author)Remarkable 3D flow structures occur at river confluences with small density differences due to differences in sediment concentration or temperature. We explain these by comparing numerical simulations for an idealized confluence with aerial photographs of several river confluences where color differences express the pattern of density...journal article 2020

(author), Aerts, Jeroen C.J.H. (author)We assess the suitability of ECMWF Integrated Forecasting System (IFS) data for the global modeling of tropical cyclone (TC) storm surges. We extract meteorological forcing from the IFS at a 0.225° horizontal resolution for eight historical TCs and simulate the corresponding surges using the global tide and surge model. Maximum surge heights...journal article 2019

Vonach, Tanja (author), Kleidorfer, Manfred (author), Rauch, Wolfgang (author), Tscheikner-Gratl, F. (author)The calibration of models for urban drainage systems has become more and more important as especially the usage of detailed models has increased considerably over the last years as the basis for planning and design. Still the effects originating from the choice of data used for model calibration are little known and advice on planning...journal article 2019

Vonach, Tanja (author), Tscheikner-Gratl, F. (author), Rauch, Wolfgang (author), Kleidorfer, Manfred (author)Although calibration of a hydrodynamic model depends on the availability of measurement data representing the system behavior, advice for the planning of necessary measurement campaigns for model calibration is scarce. This work tries to address this question of efficient measurement site selection on a network scale for the objective of...journal article 2018

van Bijnen, J.A.C. (author), Korving, J.L. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)Due to a variety of contaminants in floodwater, exposure to urban pluvial flooding may pose a health risk to humans. In-sewer defects may cause increased pluvial flooding, possibly increasing health risks. This paper addresses the impact of in-sewer defects on urban pluvial flooding and, subsequently, on infection probabilities for humans. As...journal article 2018

(author), Broekman, R (author)In this paper, we present a novel Kalman filter approach to combine a hydrodynamic model-derived lowest astronomical tide (LAT) surface with tide gauge record-derived LAT values. In the approach, tidal water levels are assimilated into the model. As such, the combination is guided by the model physics. When validating the obtained “Kalman...journal article 2017

(author), Scussolini, Paolo (author), Winsemius, H.C. (author), Ward, Philip J. (author)Estimating the current risk of coastal flooding requires adequate information on extreme sea levels. For over a decade, the only global data available was the DINAS-COAST Extreme Sea Levels (DCESL) dataset, which applies a static approximation to estimate extreme sea levels. Recently, a dynamically derived dataset was developed: the Global...journal article 2017

Hilgersom, K.P. (author), Zijlema, Marcel (author), van de Giesen, N.C. (author)The three-dimensional (3-D) modelling of water systems involving double-diffusive processes is challenging due to the large computation times required to solve the flow and transport of constituents. In systems that approach axisymmetry around a central location, computation times can be reduced by applying a quasi 3-D axisymmetric model setup....journal article 2016
