Short summary
For the dike strengthening project KIJK a study has been undertaken to optimize the amount of subsidence. Based on archive information originally a subsidence rate of 11 mm/year is used in the design calculations. This means that for a 50-year period an additional 0.55 m must be considered which does not comply with the macro-stability problems of the dike. Based on INSAR and LiDAR measurement data and reanalysing the archive data, the rate of subsidence is determined at an average of 8 mm/year.
