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 …

In recent years, the deterioration of urban rivers, due to human activity, has been receiving increasing attention. Canalized rivers are being restored or rehabilitated to restore wildlife and bring back a more natural ecosystem. This shift in the way how we look at our rivers has also resulted in the …

Canalisation of the Liesbeek River has resulted in a deterioration of its ecosystem. In order to stop the deterioration of the Liesbeek River. The Rosebank village green area of the Liesbeek River is being rehabilitated. However, it is not known how the hydrology and morphology of the Liesbeek River …

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 …
