The Netherlands is dependent on artificial structures for water safety. In addition to water safety the artificial structures also provide habitat for different aquatic species. When designing artificial structures like dikes and breakwaters adjustments can be taken to increase species richness or stimulate …

Dit werk beschrijft de fabricage van een op titaniumcarbide nanodeeltjes gebaseerde inkjet-geprinte flexibele bidirectionele stromingssensor. Het ontwerp van de stromingssensor bestaat uit een met inkjet geprinte titaniumcarbide piëzoresistieve spanningsmeter op een polyester cantilever. De sensoren …

The research concerns a currently developed project of implementing a tidal power harnessing system in the structure of Brouwersdam. The system would exploit hydraulic head difference between two water bodies and using gravity caused flow, generate electricity. As a side-effect to such system, hydraulic …

This study originates from an increasing demand for seaweed cultivation. HZ University of Applied Sciences, together with farmers, under the umbrella “Living Lab Schouwen Duiveland” will conduct a field study to assess the possibilities for introducing brown seaweed cultivation at or near existing mussel …

Introducing a hyperbolic vortex into a showerhead is a possibility to achieve higher spray velocities for a given discharge without reducing the nozzle diameter. Due to the introduction of air bubbles into the water by the vortex, the spray is pushed from a transition (dripping faucet) regime into a …

The native fish populations in New Zealand have proven to be declining. There are various reasons for this change in population size, one of the biggest being structures that form barriers to migration. This shows the need for fish passage options that are better adjusted to these ‘weaker’ swimmers and …

Introduction In the harbor of Zierikzee there is a strong tidal influence. The difference between the water levels during high and low tide lies around the three meters. The harbors De Oude Haven and ‘T Sas fall dry during an extremely low tide. When these harbors fall dry, foundations will come in …

Urban flood prevention is an intensifying prerequisite of urban inhabitation due to a multiplicity of threats to population health and property. One of the components of urbanisation that can fail to fulfil its function and cause urban flooding is gully pot clogging. Frequently this is the result of …

A few years ago the Dutch government set goals for sustainability. These goals include switching to fully sustainable energy production by 2050. Using only conventional sustainable energy production methods like solar panels and wind turbines will not result in achieving the set goals, so alternative …

Water velocity in rearing units for Atlantic salmon post-smolt can influence fish robustness. Studies have shown that training at velocities between 1-2 body lengths/second (bl/s) increases disease resistance in salmonid species. Monitoring and timely adjustments to the water velocity during post-smolt …
