Hondsbossche and Pettemer Sea Defence completed
On Monday, March 16 , the Dutch Minister Schultz 'opened' the coastal reinforcement of Hondsbossch and Petten, see http://www.kustopkracht.nl. Svašek Hydraulics has determined the maintenance volume for this sandy reinforcement which is necessary to ensure that the coastal defense is also still sufficiently secure over 20 years. For more information about the role of Svašek in this project view our project sheet.

Work on Marina Cadzand-Bad has started
The weak link Cadzand-Bad is reinforced by constructing a marina. The construction works for this marina have recently started. Svašek Hydraulics was involved in the design and optimisation process of the marina. On behalf of the Waterboard Scheldestromen, Svašek was responsible for the quality assurance during the design and construct phase of the project.
Svašek Hydraulics has written design reports of the sea defence and has applied various numerical wave models. The detailed design conditions are derived using SWAN. Wave penetration between the breakwaters is simulated with HARES. FINEL2D is applied to forecast morphological development for different layouts of the marina and to assess the safety for swimmers.

PhD-Thesis Lynyrd de Wit (cum laude)
14 January 2015
Lynyrd de Wit, employee at Svašek Hydraulics, has defended his PhD-thesis "3D CFD modelling of overflow dredging plumes" successfully. Lynyrd has gained his PhD cum laude.
3D CFD simulations, lab experiments and field measurements are used to get more understanding of the turbulent near field overflow dredging plume mixing. The focus has been on the most often used dredging vessel: a trailing suction hopper dredger (TSHD). Near field overflow dredging plume mixing is important because it determines the far field dredging plume characteristics and deposition which are essential to know in order to be able to assess the environmental impact of a dredging project. The most important near field mixing processes have been identified in this study. The insights are translated to be usable in every day dredging engineering practise and used in the IMPROVE (IMPact Reducing OVerflow Extension) concept to reduce the environmental impact.
