Wiegel, M.F. (author), de Boer, W.P. (author), van Koningsveld, M. (author), van der Hout, A.J. (author), Reniers, A.J.H.M. (author)Seaport operability is key to the economic viability of ports. Metocean conditions (e.g., wind, short waves, and infragravity waves) affect this operability when certain thresholds are exceeded. This paper describes a method for the global mapping of seaport operability risk indicators using open-source metocean data. This global-scale...journal article 2021

Performance evaluation of wave input reduction techniques for modeling inter-annual sandbar dynamicsde Queiroz, Bruna (author), Scheel, F. (author), Caires, Sofia (author), Walstra, D.J.R. (author), Olij, Derrick (author), Yoo, Jeseon (author), Reniers, A.J.H.M. (author), de Boer, W.P. (author)In process-based numerical models, reducing the amount of input parameters, known as input reduction (IR), is often required to reduce the computational effort of these models and to enable long-term, ensemble predictions. Currently, a comprehensive performance assessment of IR-methods is lacking, which hampers guidance on selecting suitable...journal article 2019

Athanasiou, Panagiotis (author), de Boer, W.P. (author), Yoo, Jeseon (author), Ranasinghe, Roshanka (author), Reniers, A.J.H.M. (author)Understanding long-term sandbar dynamics can be crucial for informed coastal zone management, but is often hampered by data availability. To increase the number of sandbar observations available from bathymetric surveys, this study proposes and evaluates a method to manually extract the sandbar location using freely available satellite imagery...journal article 2018

Hagenaars, Gerben (author), de Vries, S. (author), Luijendijk, Arjen (author), de Boer, W.P. (author), Reniers, A.J.H.M. (author)Measured trends and variability in shoreline position are used by coastal managers, scientists and engineers to understand and monitor coastal systems. This paper presents a new and generic method for automated shoreline detection from the largely unexplored collection of publicly available satellite imagery. The position of the obtained...journal article 2018

Athanasiou, Panagiotis (author), de Boer, W.P. (author), Tonnon, Pieter Koen (author), Yoo, Jeseon (author), de Schipper, M.A. (author), de Vries, S. (author), Ranasinghe, Roshanka (author), Reniers, A.J.H.M. (author)Nearshore sandbar patterns can affect the hydrodynamics and, as a result, the beach morphodynamics in the nearshore zone. Hence, spatial and temporal variability in the sandbars can influence beach accretion and erosion. Understanding the variability of the sandbar system can therefore be crucial for informed coastal zone management. So far, the...journal article 2018
