Flood Protection

A prerequisite of a good flood protection system is a sensitive and holistic approach to the area requiring the protection.

The first step of designing a flood protection system includes the acquisition of reliable hydraulic data, which is normally derived from historic records of the relevant area. The flood protection system is then proposed for a level of a nominal flow increased by a safety freeboard. From the technical point of view, the flood protection is implemented by means of dikes, embankment walls and modern mobile barriers or a combination thereof. Flood protection systems must incorporate requirements concerning environment and often encompasses protection of streams above the flood-prone area by making use of the existing overflow-lands and construction of flood release basins or retention reservoirs.
