In the Netherlands we have a history of living with water. Dikes, both at the sea and at rivers, need to protect us against flooding. The height of the dikes in the Netherlands needs to be increased in the future. Adjustment is needed because of climate changes, raising sea level and ongoing settlements. If raising of the crest level is required, stability is best increased by widening the dike. However, this is not possible in case of existing buildings at the land side and in the case narrowing of the river flow section is not allowed. Within this framework the project INnovations on Stability Improvement enabling Dike Elevations (INSIDE) started in 2001.
