IJkdijk

Stichting IJkdijk is the innovative dike monitoring organisation for inspection and testing based on sensor systems. This development programme results in nationally and internationally marketable dike monitoring systems (smart levees). The smart application of the monitoring philosophy leads to significant cost savings and deferred investments for water management authorities both in the Netherlands and abroad. Stichting IJkdijk anticipates that all Dutch water management authorities will be operating this philosophy and will be monitoring their dikes with innovative systems in cases where it is worth doing so.

Between 2007 and 2010 Stichting IJkdijk conducted groundbreaking experiments in dike monitoring with the aid of sensor technology. The next stage of the IJkdijk development programme began at the end of 2011. 

Objective 

The objective for the years to come is to continue to develop dike monitoring systems. The IJkdijk development programme runs until the end of 2014. Once the IJkdijk programme has been completed, private sensor technology companies should be in a position to deliver completely validated systems to water management authorities and for all dike types. 

Development programme elements

The programme for the continued development of the IJkdijk monitoring systems until 2014 comprises four elements:

  1. New validation tests – experiments to establish whether the various sensor systems can predict the failure of a dike and provide vital support for the management, testing and strengthening of dikes and for disaster management.
  2. Extension of LiveDijken (‘live dikes’) – equipping existing dikes with sensor systems to measure the actual strength of these dikes and avoid incurring unnecessary costs. Intended as an early warning for emergencies, as support for forecasting management and to produce a more accurate design. When it is necessary to strengthen a dike the sensor data can be used to produce an optimum reinforcement plan. 
  3. Upscaling of the LiveDijken in size (from development setting to professional approach) – LiveDijk XL 
  4. Development of the Dike Data Service Centre – a system for collecting all data from the IJkdijk experiments and LiveDijken. The DDSC streamlined information makes data available to the water management authority in a simple form. Instruments that facilitate analyse can be linked to this. Dike managers in the Netherlands are thus given an impression of the flooding risks and crisis teams are able to make better decisions. Also, the management and design of the dike can be adapted to accurately estimated risks, which places cost savings in reach.

Validation tests

The All-In-One Sensor Validation Test was conducted at purpose-built full-scale dikes at the IJkdijk location in Booneschans in August and September 2012. Various sensors, instruments and data interpretation and presentation options were tested in this context. The experiment focused not on one specific failure mechanism as with the previous macro-stability and piping tests, but on various mechanisms. The All-In-One tests concerned the predictive ability of full service senor systems: can the sensors predict the collapse of the dike? And how can the sensors contribute optimally to the management of dikes by water boards? The results of the All-In-One Sensor Validation Tests will be published on this site when available.

Sponsoring

The IJkdijk development programme is sponsored with contributions from the Ministry of Infrastructure and Environment, the Ministry of Economic Affairs, Agriculture and Innovation, STOWA, the Dutch business community, Dutch water boards, the innovation programme Flood Control 2015, the Province of Groningen and the Directorate General for Public Works and Water Management.
