van Koelen, Luc (author)Weirs are constructed inside rivers to manage the water level. On the one hand they need to be designed sufficiently strong to prevent failure or destruction, while on the other hand they need to be economically feasible. If a structure is designed too strong, unnecessary costs are made and the structure becomes too expensive.<br/><br/>One of...master thesis 2022

Arends, Jon (author)This research aims to explore sediment transport behavior and accumulation caused by run-of-river weirs in order to examine there feasibility for sustainable sediment mining purposes in the White Volta River. Weirs are used to raise water levels up-stream to increase water levels and storage, but their is little information regarding sediment...master thesis 2022

Haile, Abem (author)The Meuse is a river in West-Europe which rises at the Langres Plateau and flows from France through Belgium and the Netherlands. The river has always been an important shipping route, even though its navigability has been problematic in the Netherlands. To solve this problem seven weirs were constructed in the Dutch part of the Meuse. They are...master thesis 2022

Ligtenberg, Jourian (author)The river Waal is part of an economic important transport-corridor that connects the ports of Antwerp, Rotterdam and Amsterdam to Germany. Ongoing processes such as (1) climate change, (2) large scale river bed erosion and (3) up-scaling of vessels threaten the future navigability of the river. This will lead to massive economic damages as taken...master thesis 2022

Nina, Yvan Arosquipa (author), Shi, Rui (author), Wüthrich, D. (author), Chanson, Hubert (author)At hydraulic structures, some strong interactions may develop between fast flowing waters and the air adjacent to the water in motion that enhance the air-water transfer of atmospheric and volatile gases in the flow. In turn, in-stream structures may contribute to the aeration and re-oxygenation during overflow. The present study aims to...journal article 2022

Yildiz, B. (author), Uijttewaal, W.S.J. (author), Bricker, J.D. (author), Mosselman, E. (author)Weirs are flow control structures that can be used for flow diversion purposes. They are classified according to section geometry or their length in the flow direction. For sharp-crested rectangular weirs, Rehbock [1] derived stage-discharge equations. In contracted geometries, streamlines curve at the approach flow leading to variations in flow...conference paper 2021

Stikvoort, Bram (author)In the Meuse seven weirs are located in the Dutch reaches, controlling the water level to enable inland navigation through the river. The weirs are being scheduled for replacement, where weir Grave is the first one in 2028. They are reaching their end-of-life time. One of the main issues that became of more importance in the recent years is ship...master thesis 2020

van Os, Annemarie (author)This experimental study is about the bed-load transport over inlet sills of longitudinal training walls. The focus is on the flow structures around the inlet: the shape, the processes and the effect on sediment transport. Groynes have been replaced by longitudinal training walls in an 11-km long pilot project to optimize training of the river...master thesis 2020

de Heer, Danny (author)The weirs in the river Meuse reach their theoretical lifespan. The weirs were built in the early 1930s and now one is faced with a replacement task. Various studies have been carried out in recent years on the future of the weirs in the river Meuse. This concerns research into the entire weir system, different types of weirs and the way in which...master thesis 2020

Verbeek, M.C. (author), Labeur, R.J. (author), Uijttewaal, W.S.J. (author)An economical way to harvest tidal energy is by integrating free stream turbines in coastal infrastructure. While numerous studies have investigated how turbines should be arranged in idealized geometries to optimize their performance, only a few have considered the influence of realistic bed features. This research investigates the influence...journal article 2020

Frijns, Ruben (author)In contrast with other Dutch rivers parts, human measures in the upstream part of the River Meuse did not mainly focus on discharging surplus water, but on retaining water in dry periods. Almost 100 years ago seven weirs were constructed in the River Meuse to enable transport of coals. The structures reach, due to concrete degradation, the end...master thesis 2019

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

van Oorschot, Harm (author)On the 29th of December 2016 a large Rhine ship loaded with 2000 ton benzene sailed through the weir at Grave, located in the river Meuse in the Netherlands. The accident created a large gap in the weir and within 12 hours the upstream water level decreased by a maximum of 3 meters. Due to this decreased water level shipping was limited,...master thesis 2018

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

Verduijn, M. (author)The Meuse in the Netherlands is since the 1920s dammed by 7 weirs, which are located near Borgharen, Linne, Roermond, Belfeld, Sambeek, Grave and Lith. The weirs regulate the water levels in the canal sections (=stuwpanden) to provide sufficient depth for navigation. The management of the weirs is regulated by water level measurements at...master thesis 2015

Rombouts, P.M.M. (author), Tralli, A. (author), Langeveld, J.G. (author), Verhaart, F. (author), Clemens, F.H.L.R. (author)Being able to accurately determine weir discharges is of key importance in urban water management. The most common method is performing a level measurement and calculating the discharge using the standard weir equation. Since this equation is only valid in certain conditions, this can lead to large deviations from the actual discharge. In this...conference paper 2014

Tuin, H.G. (author)The Nederrijn and Lek are presently dammed by three weirs, build in 1960 till 1970, which are located near the village of Driel, Amerongen, and Hagestein after which they are named. Weir Driel regulates the distribution of water at the IJsselkop for dammed conditions (discharges lower than 2350 m3/s at Lobith). A minimum discharge of 285 m3/s...master thesis 2013

Ren, Y. (author)The main objective of the study is to understand the effects of breach properties (e.g. the top width, the depth and the bottom width of the breach) on the breach flow. The breach flow was modeled as flow over a compound broad-crested weir. A laboratory experiment was carried out with a fixed weir model in a flume. Five cases with different...master thesis 2012

Ali, S. (author), Uijttewaal, W.S.J. (author)At high water stages obstacles in the floodplains of a river contribute to the flow resistance. In particular the elevated vegetated parts are expected to play an important role. The objective of this study is to estimate and parameterize the form drag due to vegetated oblique weir-like obstacles. An experimental study has been carried out in...conference paper 2011
