van Alderwegen, Earvin (author)Large-scale measures within the river programmes such as Room for the River, Natura2000 and Water Framework Directive have increased the biodiversity in Dutch rivers and have achieved a more natural landscape. However, recent river programmes have shown conflicts between safety against flooding and riverine nature rehabilitation with maintaining...master thesis 2021

Harms, Johan (author)Currently multiple projects investigate the effect of lowering the crest of groynes in the Dutch rivers with the aim to lower the backwater effect of groynes under high water levels. There is a major uncertainty however in the modelling of groynes, and therefore in the prediction of the effect of groyne lowering. Currently submerged groynes are...master thesis 2021

Pasman, Rutger (author)Ships in rivers create waves and these can have a negative impact on fish habitats along the river banks. A modelling study is carried out to investigate how these ship-induced waves can be damped in groyne fields by making structural modifications to the groynes. For this purpose, different types of openings (notches) are applied to the groynes...master thesis 2020

Ambagts, Lindert (author)In submerged conditions groynes add resistance to a river, thereby increasing the water levels for a particular discharge. Groynes are modelled in two ways, either they are included in the bed topography when the grid resolution is sufficiently high or with a sub-grid parametrisation when the grid cell-size is larger than the geometry of the...master thesis 2019

Chit Yan Toe, Chit (author)In this research two problem statements are defined, namely (1) the validity of the assumption that groynes and weirs are equivalent in hydraulic models, and (2) the difficulty of modelling groynes and weirs in the 3D numerical solver package OpenFOAM. Using the incompressible 3D Navier-Stokes equations solver for multiphase phase flows, the so...master thesis 2018

van Broekhoven, R.W.A. (author)Om in de toekomst de veiligheid rondom de Nederlandse rivieren tegen overstromen te waarborgen heeft het kabinet het standpunt "Ruimte voor de Rivier" ingenomen. Hierin staat beschreven dat in 2015 een pakket aan maatregelen ervoor moet zorgen dat een maatgevende Rijnafvoer van 16.000 m³/s binnen de gestelde veiligheidsnormen moet kunnen worden...master thesis 2007

Anonymus, A. (author)In 2006 is door Rijkswaterstaat een prijsvraag uitgeschreven voor het ontwerp van een innovatief ontwerp voor een rivierkrib. Een viertal inzendingen zijn uiteindelijk genomineerd: De Eilandkrib, Jack de Kribber, De module krib en De Zelfregulerende krib. Bijzondere vermeldingen waren er voor de Modulaire Variabele krib en de Powerkrib.report 2006

Crossman, M. (author), Segura-Dominguez, S. (author), Allsop, W. (author)Coastal rock structures are widely used in coastal engineering for a variety of purposes, including controlling the morphological development of beaches and providing protection against coastal erosion or flooding by wave overtopping. Strict adherence to existing design guidance has resulted in many of these structures being built using multiple...report 2003

Perdok, U. (author), Crossman, M. (author), Verhagen, H.J. (author), Howard, S. (author), Simm, J. (author)The performance and durability of timber groynes (or 'groins') is highly dependent on the design and detailing of the structure. Using knowledge and experience developed over generations an effective functional design can be achieved, which may ultimately result in lower whole life costs and provide environmental advantages over alternative...conference paper 2003

Yossef, M.F.M. (author)Groynes are structures constructed at an angle to the flow in order to deflect the flowing water away from critical zones. They are made of stone, gravel, rock, earth, or piles, beginning at the riverbank with a root and ending at the regulation line with a head. They serve to maintain a desirable channel for the purpose of flood control,...report 2002

Jörissen, J.G.L. (author)Als gevolg van natuurlijke processen, zoals getijde en golven, is een kustomgeving voortdurend aan verandering onderhevig. Hierdoor is een zandige kust niet altijd stabiel en kan er op sommige plaatsen een achteruitgaande kustlijn worden aangetroffen. Indien zo'n achteruitgaande kustlijn een structureel karakter heeft, wordt dat vaak veroorzaakt...master thesis 2001
