Environmental Enhancement of Infrastructure
Houtrib Dike Pilot Project The dike between the cities of Lelystad and Enkhuizen, the Netherlands
The Houtribdijk is a dike in a lake environment. When a dike becomes inadequate for its intended purpose, the traditional approach to dike reinforcement—building a bigger dike—is usually the first option that comes to mind. In this case, however, creating a sandy foreshore was an alternative solution that was more attractive for several reasons: it was cheaper to install and maintain than a traditional dike upgrade and it is more sustainable and improves nature and leisure facilities in the area. The sandy foreshore was constructed in 2014; in 2015, a section was partially planted with a variety of vegetation. The different conditions will be monitored and evaluated for their effectiveness. This pilot project was implemented as part of EcoShape’s Building with Nature innovation program. The Rijkswaterstaat’s Dutch Flood Protection Program was the project’s client.
