Improvement of the inspection of flood defence systems

This website contains information about the Program PIW that is executed by Rijkswaterstaat Waterdienst and STOWA. The program is focused on the improvement of the inspection of flood defence systems (dikes, dams, dunes) in the Netherlands.

The inspection of these flood defence systems is an important task in order to be aware of the weaknesses of the assets and be able to repair these weaknesses in time. In 2003 and 2004 two  dike breaches occurred in Wilnis and Stein, two dutch villages. After these incidents, the program was started to research how the quality of the inspections can be improved.

The program will lead to a guideline for the execution of inspections. Next to this guideline, the program contains the following activities:

  • Development of a registration tool (Digispectie) that can be used to insert observations (text and photo’s) at a certain GIS-location on a hand-held computer;
  • Development of a catalogue with images of potential damages that can occur (Digigids);
  • Real-time monitoring of dikes using sensors that are placed inside the dikes (LiveDijk).
