How does an FCA-RT work?

A flood control area with reduced tides combines safety with conservation. The inflow of the daily tides creates tidal nature. In severe weather, the area collects excess water.

In a flood control area with reduced tides, we combine safety with conservation. We do this by installing special sluices in the flood control area. Every day, the high intake sluice allows a little bit of water flow into and out of the area – in time with the rhythm of ebb and flow. After some time, this process results in the creation of tidal nature with mudflats and marshes.

When flooding occurs, the water runs over the overflow levee. The ring levee protects the residential areas, roads and other infrastructure situated beyond it from flooding. Once the storm has died down, the low discharge sluice allows the water to drain away again.
