Spatial Data Infrastructures (SDIs) have been developed over the last decades all over the world. SDI is the integration of several components to create a platform which enables a wide variety of stakeholders to access, share and use spatial data in an efficient and effective way. To stimulate the SDI development effectively and efficiently, it...

In the area that is managed by the waterboard Amstel, Gooi and Vecht, some deep polders are located. Most of them attract large amounts of brackish seepage. This seepage not only contains salt, but also nutriënts.<br/>Without hydrological intervention, the waterquality in the area would suffer significantly from the brackish seepage. To prevent...

Challenging neighbourhoods in large cities most often lack social coherence. Meaningful social interaction between citizens in such neighbourhoods is needed to increase coherence, and games may be a means to this end. This paper reflects on the structure of a dedicated game design workshop with teenagers from 12 to 16 years of age designed to...

Aims Most swimming pools use residual disinfectants like chlorine for disinfection. The use of chlorine has several drawbacks: some waterborne-pathogens are chlorine resistant and disinfection by-products (DBPs) may be formed which are associated with various health risks. Therefore, an alternative treatment was developed which consists of...

Swimming pools are traditionally disinfected with a residual disinfectant such as sodium hypochlorite. Nowadays, swimming water without a residual disinfectant is increasingly popular, as can be seen by the growing number of (natural) swimming ponds (Weilandt 2015), but health risks for bathers do raise concerns for these type of pools, so some...

Aims<br/>The basis of this study lies in hygiene of swimming pools, where it is argued that taking a pre-swim shower would lead to a decrease in release of pollutants in the swimming pool, which in the end would lead to the decrease of health issues as red eyes and asthma. However, previous research has shown that not even half of the swimming...

Previous studies on contamination of swimming pool water showed that the hygienic behaviour of swimmers is the most important factor. The suggested hygienic behaviour is; having a pre-swim shower and using the toilet when nature calls. Knowing the importance of hygienic behaviour is one thing, knowing how to change hygienic behaviour is...

The Dutch Caribbean consists of two island groups, the Leeward Antilles off the Venezuelan coast separated from the Windward Islands east of Puerto Rico over distances of the scale of the Caribbean Sea itself. Climate change in the Caribbean Sea is predicted to lead to rising sea levels, warming waters and changing eddy fields. Warming waters...

One of the long-standing issues in the field of corporate real estate corporate strategy. Extensive research into existing approaches brought valuable insights into steps, components and variables that are needed in the alignment process. Despite that, it is not clear if existing approaches had much uptake in practice and they fall short in a...

Long term morphodynamic simulations are used for predicting the impact of climate change and human interventions in our estuarine and coastal regions. The accuracy of this type of simulations suffers generally from low resolution grids. Eventhough high resolution bathymetry data is increasingly more available thanks to new measurement techniques...

Salt marshes are a characteristic feature of estuaries and coastal seas. They are found in the upper coastal intertidal zones between land and water, which are regularly flooded by tides and surges. They are covered with salt-tolerant vegetation types, such as herbs and grasses. Sheltering from continuous intense hydrodynamic forcing by waves...

The flow velocities in tidal channels are already rather complex by the presence of various tidal components, wind driven flow and estuarine circulations. An extra level of complexity is introduced when the flow on top of an intertidal<br/>flat is considered (Le Hir, 2000). This research aims at understanding the complex flow patterns on top of...

River plumes, also regions of freshwater influence , are important features to understand because of their impact on the current structure, stratification and the transport of fine sediments, nutrients and contaminants. One important river plume is the Rhine ROFI. Prior studies have sought to understand far-field dynamics where cross-shore...

Along-channel and cross-channel sediment transport in tidal estuaries is usually driven by tides, density gradients, Coriolis’s force, wind stress, channel curvature and bathymetric variations. Since the water motion is influenced by density-induced gravitational circulation which in turn affects the salinity distribution, the coupled water...

A computational model for multiple CO2 leakage mechanisms is introduced. Leakage through cap layers and abandoned wellbores are considered. For the first, leakage in a rigid heterogeneous layered medium constituting layers of different physical properties is simulated. Such a leakage exhibits a<br/>discontinuity in the saturation field at the...

When rivers are forced by statistically invariant boundary conditions (i.e. an upstream water discharge, upstream sediment discharge and downstream base level that fluctuate around constant mean values), and are not subject to any forcing with a temporal trend (e.g. no uplift/subsidence, no sea-level rise), they tend to a morphodynamic...

Over the past centuries natural river banks have been transformed into banks with artificial revetments or sheet piles to protect them from erosion. Important river features for flora and fauna have disappeared and the ecological quality of the river reduced dramatically. Recently, the importance of the ecological function of rivers has been...

Confluences are fascinating elements in river systems. The merging of tributary rivers produces complex hydrodynamics that can play an important role in sediment transport problems, ecological studies or the routing of a pollutant. If the two merging rivers originate from different regions they can have different characteristics. One such a...
