Workers are an important factor in the implementation of a construction project. Applying ergonomic postures for workers in the projects is necessary to minimize the risk of work accidents and the risk of experiencing musculoskeletal disorders (MsDs). The use of lightweight brick for wall construction …

Waterschap Scheldestromen is carrying out a particularly innovative project named Multiflexmeter (MFM), of which the objective is to look for ways to measure the soil resistance . This means some properties and characteristics of water needs to be researched on, such as the salinity and the corresponding …

The majority of Dutch peatlands are drained and used intensively as grasslands for dairy farming. This delivers high productivity but causes severe damage to the provisioning of ecosystem services. Peatland rewetting is the best way to reverse the damage, but high water levels do not fit with intensive …

We report the detection of tryptophan at sub-ppb levels for a fluorometer based on Fresnel lenses and low-cost electronics. These fluorometers can be used to detect fecal contamination in drinking water, indicated by tryptophan-like fluorescence.

Stormwater runoff can contain high amounts of Potential Toxic Elements (PTE) as heavy metals. PTE can have negative and direct impact on the quality of surface waters and groundwater. The European Water Framework Directive (WFD) demands enhanced protection of the aquatic environment. As a consequence, …

Ever since lake Volkerak got its status as a partially closed-off lake in the late ‘80s, excessive (cyanobacterial) algae blooms in the summer period have been a consistently occurring problem. This research aims to investigate the location-specific effectiveness of wetlands and floodplains in nutrient …

Waterschap Scheldestromen has a measurement device named Multiflexmeter. It uses the LoRaWAN technology to send the measurement data to the gateway. But sometimes, the Multiflexmeter can not connect to the gateway to send data because the line of sight is blocked. So the company is seeking a design of …

Climate change can be described as both a natural and an artificial process that affects all life on earth. One of its consequences is the rising of sea levels which can cause problems in coastal areas, such as increasing the pressure of saline groundwater. Due to this increased pressure, this saline …

Climate change and changing land use challenge the livability and flood safety of Dutch cities. One option cities have to become more climate-proof is to increase infiltration of stormwater into soil through permeable pavement and thus reduce discharge of stormwater into sewer systems. To analyze the …
