Settlement Rod Monitoring with the Locator One – Innovation for Strong and Sustainable Dikes

Strong dikes are essential for our protection against high waters. For reliable and sustainable monitoring of settlements and ground movements, the Locator One is the ideal solution. This innovative, CO2-neutral sensor platform performs accurate deformation measurements, allowing both the stability of settlement rods and the structural health of dikes to be monitored. Equipped with GNSS and radar sensors, the Locator One records sub-centimeter accurate measurements and provides valuable predictability for the management of dikes and other critical infrastructure.

How does the Locator One Work for settlement rod monitoring?

With the Locator One, you can easily monitor the vertical movement of the ground surface and the thickness of embankments around dikes. The raw measurement data from the settlement rod is automatically sent to a cloud environment, where the data is processed in near real-time. This enables engineers to continuously monitor the structural health of the dikes and take preventive measures in a timely manner.

Key benefits

  • Accuracy: The Locator One guarantees consistent data with an accuracy of up to 5 mm on the Z-axis and 3 mm on the X-Y axis. This allows for precise monitoring of changes in dike heights and ground subsidence.
  • Predictability: Daily data collection at fixed times enables engineers to make reliable predictions about expected settlements and the remaining time until stabilization. This increases not only the accuracy but also the predictability of dike monitoring.
  • Safety: Using the Locator One reduces the need for human presence on construction sites, significantly enhancing safety and reducing the risk of accidents.
  • Sustainability: With solar energy and a supercapacitor, the Locator One reduces CO2 emissions by minimizing measurement rounds and traffic movements.

Installation and monitoring

  • Installation: The Locator One is placed on the settlement rod to determine the height of the original ground surface. When embankments are raised, the device is easily moved to an extension, ensuring consistent measurements. Thanks to intelligent algorithms, the Locator One recognizes the new height and automatically adjusts the data.
  • Data transfer and analysis: The measurement data is sent via an IoT network to the cloud and analyzed by Basetime. This provides you with near real-time insights into the current situation.
  • Dashboard or API: The measured data is accessible through the Basetime dashboard or can be directly integrated into your own information system. Our data can be customized to meet the specific needs of your dike management project.

Settlement rod monitoring in the Gorinchem-Waardenburg dike reinforcement: safe, sustainable, and accurate

Between 2023 and 2025, the dike between Gorinchem and Waardenburg will be raised, widened, and reinforced over a distance of 23 kilometers. For continuous and reliable monitoring of the embankments and dike reinforcement, traditionally, the dike body is surveyed by a land surveyor. However, this is physically demanding work, especially due to the heavy clay soil, and comes with risks such as collision and tripping hazards. In the search for safer and more innovative measurement methods, the Locator One proved to be the ideal solution for this project. Read more about this in the case study (link to GoWa case study).

“At the start of the project, we didn’t exactly know what benefits the application of the Locator One would bring, but we were looking for innovative and safer measurement methods. We invested in this concept because we believed in it. Now, in the implementation phase, we can see the results!” says Pieter van Dueren den Hollander (Discipline Leader Geodesy, Heijmans).
