Read the news article on the collapse of the IJkdijk in the All-In-One experiment

 In 2007 and 2009 two experiments were held at the IJkdijk location based on the theme of the failure mechanisms of macrostability and piping. A new experiment followed in 2012: the ‘All-in-one Sensor Validation Test’ (AIO-SVT).

Predictive ability

The primary aim of this experiment was to study the predictive ability of full-service sensor systems, such as a sensor combined with data processing and information systems that gives a timely and reliable warning if there is a danger of a dike collapsing.

Test dikes

Two test dikes were built for the AIO-SVT, that have been used during the experiment to simulate two failure mechanisms:

  • Facility for piping and microstability
  • Facility for macrostability and microstability.

Various sensor types were installed for both facilities. After the dike was built the test dikes can were burdened until they collapsed. This gives the sensor developers the opportunity to test and validate their equipment.


The sensors supplied a wide range of data during the tests. This data were centrally stored and used for the realtime visualisation of measurements (dashboard showing the sensor results). The data was directly interpreted for detection and warning systems. The experiment was followed by validation of the sensors, detection and warning systems. As soon as available, the report and publications will be published on this website.

Final tests at the location

The IJkdijk All-in-one Sensor Validation Tests were the final tests at the IJkdijk location in Booneschans. The site has been handed over to Staatsbosbeheer in October 2012.


The steps taken during the All-in-one Sensor Validation Test were as follows (all 2012):

  • April: Contracting of the building of the test facilities (dikes)
  • Beginning of May: Awarding of the contract 
  • May – June: Building of test facilities
  • July: Installation sensors participants
  • 15 – 17 August: IT system tests
  • 20 - 26 August tests in both piping tanks
  • 27 - 31 August: Relocation of work to southern dike
  • 29 - 31 August: Test of IT systems, southern dike
  • 3 – 9 September: tests on the southern dike
  • 10 – 30 September: Space for additional tests
  • 1 - 31 October: work involving the handover of the site to Staatsbosbeheer.
