02-07-2020 The photo of June 2020 shows crop damage due to salinization above the tile drainage on an agricultural field in Texel, one of the islands of the Netherlands. Last week there was considerable salinization damage due to rising salt into the root zone above the tile drainage. Earlier within…

04-02-2020 The drinking water company Oasen, The Netherlands, manages various geohydrological models to be able to model the groundwater flow and groundwater level changes around their extraction sites. The models are used for permit applications and changes, microbiological safety analyzes, residence time…

03-03-2015 As part of the Dutch Delta Plan for Lake IJssel a broad stakeholder platform was organized. Management of the surface water level in the lake was one of the main topics discussed by the platform. To come up with the best water level management policy an in-depth physical assessment was combined with…

01-03-2015 The Dutch Water Supply On-demand Project aims at ‘smarter operational water management’. By supplying freshwater at the right place at the right time it contributes to an optimal distribution of freshwater. The project is well-described by four principles: measuring, knowing, adjusting and…

01-03-2015 The Dutch Spaarwater Project focuses on making and keeping freshwater available. Now and in the future. The project aims for subsistence freshwater storage on small-scale plots. At the moment, the project consortium is running four pilots where subsurface freshwater storage and system-oriented…

01-03-2015 The so-called Dutch Spaarwater Project focuses on making and keeping freshwater available. Now and in the future. The project aims for subsistence freshwater storage on small scale plots. At the moment, the project consortium is running four pilots where subsurface freshwater storage and…

01-03-2015 In order to improve flood prevention, sand nourishment is used as an effective tool to reinforce the Hondsbossche sea wall. As new dunes develop, this is likely to lead to a reduction of saltwater seepage. This reduction will have its effects on the saline and brackish ecosystem in the area behind…

01-03-2015 In The Netherlands, local water boards are hold responsible for the management of river embankments, the so-called river dikes. Water board Rivierenland is accountable for administrating, controlling and maintaining many kilometres of river dikes. Dike stability is crucial for Dutch people’s safety…

01-03-2015 In the Quarter Amsterdam South-East the thickness of the geological top layer is highly variable. The vulnerability to groundwater related problems is much higher in areas where the top layer is relatively thin.
Waternet commissioned Acacia Water to perform a detailed analysis of the top layer…

01-03-2015 In order to support urban groundwater management a numeric groundwater model was developed for the Municipality of Hillegom, West of Amsterdam.
The model allows the Municipality to assess and evaluate most groundwater related issues themselves. There is no more need to continuously commission…

01-03-2015 The project site, a deep polder in the Province of Utrecht, is subject to intensive seepage, boils and uncertainty over soil stability. Over the past years the local water board and the province cooperated in developing sustainable long term planning for the polder. Within the context of these…

01-03-2015 The Climate change and salinization program for the northern Netherlands focused on the current and future impacts of salinization on high-value cash crop agriculture. A series of groundwater studies provided an insight into the role of tile drainage in salinization. Amongst others, research was…

01-03-2015 Freshwater resources are limited in the south-west of The Netherlands, while scarcity will become more pressing in this region in the near future due to sea level rise, soil subsidence and prolonged droughts. Since the region is an important agricultural area it is quintessential to address these…

01-03-2015 As part of the Dutch Delta Plan for Lake IJssel a broad stakeholder platform was organized. Management of the surface water level in the lake was one of the main topics discussed by the platform. To come up with the best water level management policy an in-depth physical assessment was combined with…

01-03-2015 Freshwater supply in a polder North of Amsterdam is uncertain. To enhance the reliability of the system Acacia Water supported the decision and policy making processes concerning future water management. Because of pro-active stakeholder involvement, the outcomes are fully acknowledged and supported…
