definitionInspection of the flood protection dikes takes place in order to observe and assess the state of the dike and especially after a storm surge events to locate damages in the dike line. Located damages will be fixed (dike recovery) to maintain the protective effect of the dike. It is the responsibility of the diking maintenance authority, or the private owner, to conduct routine and periodic inspections and maintain and repair the works to the same flood protection standard that the works were built to. Necessary funds shall be budgeted annually and set apart for the specific purpose of maintenance and repair of the flood control works. The entire flood protection system shall be inspected in detail at least once every year. Such inspections shall be scheduled prior to the high flow season allowing sufficient time to carry out any repair work needed to put the works back to design standards. Additional inspections may be necessary after each winter season to check slope erosion or sloughing, frost damage or vehicle damage to the dike crest, access ramps, access roads and turn arounds.

Co-benefits and impactsMaintenance of the protective effect of the dike.
conditionsIt may be worth considering having an asset management frameworks (in line with the ISO 55000 standard) which are designed to maintain the level of safety of all flood management assets (dams/dkyes) rather than prescriptive measures for dike management. This will ensure an asset management plan that can adapt to changing conditions rather than prescribing the tasks.
