New paper by Aguilar-Lopez et al: Failure of grass covered flood defences due to wave overtopping: a probabilistic assessment method. Transitions on dikes have a large impact on the dike stability during wave overtopping events. It is quite common to find dikes with integrated hard structures such as roads, which also represent bottom irregularities and surface roughness changes which directly influence the erosion rates of dike covers from the overtopped waves.
New paper by Anouk Bomers et al: Modelling effects of an asphalt road at a dike crest on dike cover erosion onset during wave overtopping Structures integrated in a grass-covered dike may increase erosion development. Currently, safety assessment methods for flood defences are only applicable for a conventional grass-covered dike and the effects of structures on dike cover erosion are poorly understood.
TEDxTwenteU: ‘Your water footprint revealed’ This year’s edition of TEDxTwenteU, with the theme ‘Building Bridges’, took place Wednesday May 2nd , at Concordia. A small audience of 100 people will listen to ten speakers from all over the UT. We spoke to one of them, Rick Hogeboom, whose talk is about the size of our water footprints.
Effects of environmental properties on sand wave morphology The bed in shallow shelf seas is not flat but composed of large bedforms with length scales up to 100- 1,000s of meters (Figure). A good understanding of such bed forms, such as sand waves, is of key importance for shipping safety, offshore constructions, and the deployment of cables and pipelines.
Exploring the effects of wave breaking on turbulence distributions The flow of water under wind-driven waves near the coast is highly energetic, leading to the production of chaotic, “turbulent” fluid motions. Turbulence plays an important role in the flow and the transport of sediment under waves. Therefore, understanding turbulence dynamics is crucial to understanding the behavior of waves and their effects on shoreline processes (e.g., beach erosion).
The water footprint of world’s artificial reservoirs In our group, we try to keep track of all water flows that are appropriated for human use, be it for agriculture, industrial or domestic use. So far, however, the water consumpution of man-made reservoirs has been overlooked.
Opportunity for WEM-students to join Wetskills The Wetskills Foundation invites Bachelor, Master, PhD students and recent graduates with a passion for water to apply for the Wetskills Water Challenge programme in Cape Town, South Africa, from 15 – 28 June, 2018. With water higher on everyone’s agenda than ever because of the persistent drought, your solutions to pressing Cape Townian water issues is urgently needed.
Internationally aired radioshow interviews Rick Hogeboom on water issues The Scholar’s Circle, a weekly syndicated public affairs radio show that airs on over 15 radio stations in the USA and New Zealand, has a series on water issues featuring WEM’s Rick Hogeboom. Host prof. dr. Maria Armoudian interviews Rick, panel style, to share his research with the public.
Morphodynamic assessment of side channels Side channels are often constructed to increase the conveyance capacity of the river and to increase its ecological value. As part of his PhD, Pepijn van Denderen (MFS group) estimated the development of several side channel systems and the corresponding timescales.
Waternetwerk Scriptieprijs voor Daan Poppema Voor zijn Master-scriptie heeft Daan Poppema, nu promovendus aan de Universiteit Twente, de Waternetwerk Scriptieprijs 2017 gewonnen. Hij was eerder ook al finalist voor de ‘Waterbouwprijs 2017’.
VENI -grant for Engineering Technology researchers Erik Horstman and Ismet Baran Erik Horstman and Ismet Baran from the Faculty of Engineering Technology have received a VENI-GRANT from NWO (Netherlands Organization for Scientific Research). With the corresponding amount of 250.000 euros per scientist, they can now develop new research lines.
