Automating groundwater level determination

In the municipality of Rotterdam, there are several measurement points where groundwater levels are measured. Measurements are increasingly recorded and transmitted automatically.

Goal and impact

PURPOSE: The purpose of the application is to map groundwater levels in Rotterdam and share them publicly via the national facility Basisregistratie Ondergrond (BRO).
IMPACT: The direct impact on Rotterdam residents is small. However, insight into groundwater levels is important in order to identify the risk of nuisance caused by high and/or low water levels.

Considerations

Sharing in BRO is required by law. In addition, it is important for climate adaptation for both private and public organisations and Rotterdammers to have insight into water levels.

Human intervention

Every six months, the sensor is checked. All data from that period are then checked again by a human to ensure the calculation is correct.

Technical design

In the municipality of Rotterdam, there are several points where a groundwater level can be found. At an increasing number of such points, determining the groundwater level is done automatically. Data from a sensor are used to calculate the groundwater level in relation to NAP. This data is passed on to the national facility Basisregistratie Ondergrond. On the one hand, this is a legal obligation (Wet BRO), but on the other hand it is also good for Rotterdammers and companies to know what the groundwater level is. The sensors are monitored regularly to prevent incorrect measurements and to ensure that the calculation of the water levels is as accurate as possible.

  • Based on measurements, sewage discharge is controlled. The algorithm determines whether a valve for the transit is open or closed. This makes it possible to control where this water goes during periods of high rainfall.
