Innovatieve dijkconcepten (Zw Delta) (BO-11-015-030)

In the Deltaprogramme Zuidwestelijke Delta (DP ZWD) 2013 and in the concept of 2014 it came up that innovative dike concepts score high in the optimisation process of the future safety strategies for dikes. The past year a research was conducted within the framework of the DP ZWD to determine the global change for application of innovative dike concepts in several parts of the southwestern delta. Besides that, a methodology has been developed to quantify the difference between innovative dike concepts and traditional dikes. This research showed that the chances for innovative concepts are especially favourable where social and/or political ambitions exist combined with physically suitable circumstances. The DP ZWD are in urgent need for more information on success and failure factors for the development these dike stretches at specific locations. There is also need for detailed understanding where specific physical circumstances (tide, elevation, salinity) are present that would make application of sandy solutions (suppletions) possible in combination with biobuilders" (mudflats, plates, willows, reeds). Furthermore a methodology is required to quantify the surplus value of innovative dike concepts compared to traditional ones.

The present research continues the research on innovative dike concepts. The purpose of the proposed research is to estimate the feasibilty of innovative dike concepts dike at site specific locations. A workshop with experts and stakeholders of the Deltaprogram Zuidwestelijke Delta showed that short term solutions chances for application of innovative dikes can be found especially at locations where a public or political ambition exists and where synergy is possible between water safety, nature and or recreation and where the rquired physical circumstances are present. All innovative types of dikes were technically possible in the Zuidwestelijke Delta.
