(author), Steetzel, Henk (author), Reneerkens, Michiel (author)Wave overtopping is commonly measured using overtopping tanks. In this paper, an alternative system is developed by using two laser scanners. It measures wave run-up, as well as layer thicknesses and front velocities, both during normally and obliquely incident waves on a dike in the field. The paper considers the first field validation tests...conference paper 2019

van Vledder, G.P. (author), Hofland, Bas (author), Tuin, Henry (author), van Maris, Bob (author)This paper describes a numerical evaluation of design rules for the determination of wave loads of non-breaking waves on vertical structures. Design guidelines were proposed by Sainflou (1928) and Goda (1974). These guidelines use geometric parameters of the structure, an incident wave height and a wave period. In practice (cf. CERC, 1984), a...conference paper 2019

Çakmak, Recep Emre (author), Akpinar, Adem (author), van Vledder, G.P. (author)This study determines the qualities of atmospheric wind field data in comparison with wind measurements at five locations along the Black Sea coast. For this purpose, four different wind fields were obtained from three different weather centers (NCEP, NASA, and ECMWF). Three of these are reanalyzed winds (Climate Forecast System Reanalysis...journal article 2019

Oosterlo, P. (author), van der Meer, J.W. (author), Hofland, Bas (author), van Vledder, G.P. (author)This paper considers the Eems-Dollard estuary in the north of the Netherlands, which is part of the shallow shelf sea the Wadden Sea. This estuary is a highly complex area with tidal flats and deep channels and is characterised by an offshore directed wind, posing a challenge to wave prediction models. As little measurements are available, a...conference paper 2018

van Vledder, G.P. (author), Sander, Sander Th (author), McConochie, Jason D. (author)This paper presents the results of a wave hindcast of a severe storm in the Southern North Sea to verify recently developed deep and shallow water source terms. The work was carried out in the framework of the ONR funded NOPP project (Tolman et al. 2013) in which deep and shallow water source terms were developed for use in third-generation...journal article 2016

van Vledder, G.P. (author), Akpınar, Adem (author)The swell climate of the Black Sea has been determined using a long-term 31-year wave hindcast with the thirdgeneration spectral wave model SWAN in combination with spectral partitioning. This technique enables decomposing wave spectra into individual wave systems representing wind seas or swells and computing integral wave parameters of each...conference paper 2016

Bingölbali, Bilal (author), Akpınar, Adem (author), van Vledder, G.P. (author)This study aims to assess wave energy potential and its long-term spatial and temporal characteristics in the Black Sea within the TUBITAK research project (Akpınar et al., 2015). With this purpose, a wave model (SWAN model version 41.01 driven by the CFSR winds) over the entire Black Sea was constructed. The model was calibrated using buoy data...journal article 2016

Van Vledder, G.P. (author), Zijlema, M. (author)The determination of wave conditions in partly sheltered areas is a challenging task for coastal engineers. Knowledge about these conditions is important for the design of coastal structures, the planning and operation of ports. Numerical models play an important role in the assessment of these conditions. Various types of models have been...conference paper 2014

(author)This study presents an intercomparison of a SWAN and SWASH wave model and 3D laboratory experiments for an existing navigation channel towards a harbor. Results show that the spectral refraction model SWAN underestimates the wave conditions in the channel and at the lee side of the channel especially - for longer waves travelling under a small...conference paper 2014

(author)This paper presents the application of new source terms in SWAN for the dominant water wave physics in the coastal zone: depth-induced breaking and triad wave-wave interactions. We present results demonstrating increased modelling skill in the prediction of bulk wave parameters e.g. significant wave height and of the spectral shape compared to...conference paper 2014

Alabart, J. (author), Sanchez-Arcilla, A. (author), Van Vledder, G.P. (author)Wave penetration inside harbours has been one the main issues that port planners and engineers have had to deal with in recent years. Wave conditions inside harbours trigger vessel movements, create dynamic loads on port structures and condition harbour exploitation and safety. For this reason in the recent past maritime and port engineers have...conference paper 2014

It is generally assumed that these interactions play an important role in the evolution of wind generated surface gravity waves. Therefore, present day...conference paper 2012
