As a result of the monitoring of the groundwater, time series of tens of years have been accumulated for many sites in the Netherlands. This information makes it possible to establish characteristic features of the movement of the groundwater, to recognise spatial patterns and to analyse changes in trends. Key characteristics include the highest and lowest groundwater levels that may be expected in a specific area as the result of annual seasonal patterns. This knowledge is useful not just for farmers and nature conservation but also when planning new housing developments and infrastructure. The measured data provide insight into the reaction of the groundwater to changes such as subsidence of a polder or a reduction in groundwater abstraction. This information enables predictions to be made about future changes in groundwater level. The longer the time series, the more accurate the predictions about the long-term behaviour of the groundwater. One of today’s main challenges is to predict the influence of climate change on the groundwater system. Guidelines are being developed nationally and internationally for the sustainable policy and management of our groundwater systems. DINOloket offers the user an opportunity to obtain information from DINO Groundwater about the quantity and quality of the groundwater in the Netherlands. Data from the system is currently supplied in a format that the user can easily view in a spreadsheet, such as Microsoft Excel. To ensure legibility, a limited amount of data is currently being offered.
