tract Micro wind turbines can be structurally integrated on top of the solid base of noise barriers near highways. A number of performance factors were assessed with holistic experiments in wind tunnel and in the field. The wind turbines underperformed when exposed in yawed flow conditions. The theoretical …

This paper assesses wind resource characteristics and energy yield for micro wind turbines integrated on noise barriers. An experimental set-up with sonic anemometers placed on top of the barrier in reference positions is realized. The effect on wind speed magnitude, inflow angle and turbulence intensity …

Stormwater runoff has severe negative and direct impact on the quality of surface waters and groundwater. The impact can cause chemical and heavy-metal pollution. Applying well established methods to map pollutants in urban areas and specifically in Nature-Based Solutions (NBS), such as Sustainable Urban …

Due to lack of proper stormwater drainage in the Waymouth Hills, stormwater runoff have often caused undermining of the road infrastructure and disrupting traffic flow in the study area. Sediments are often deposited to the low-lying terrain from the runoff and this reduces the storm drains capacity …

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 …

The Southwest Delta is a dynamic area where three of the largest rivers in the Netherlands flow out into the North Sea. The area is internationally famous for its natural values, but nature and human interventions have difficulty co-existing. A healthy delta can support functions that humans derive from …

We report on a first field test in which miniaturized sensor motes were used to explore and inspect an operational pipeline by performing in situ measurements. The spherical sensor motes with a diameter of 39 mm were equipped with an inertial measurement unit (IMU) measuring 3-D acceleration, rotation, …

The growing appetite of cities is one of the greatest future challenges. There is no set menu for meeting this appetite, but a trend is observed in which city authorities focus on region-based food provision. Regionalism is motivated by the importance of increased self-reliance. Besides, regional food …

A novel type of application for the exploration of enclosed or otherwise difficult to access environments requires large quantities of miniaturized sensor nodes to perform measurements while they traverse the environment in a “go with the flow” approach. Examples of these are the exploration of underground …
