Research question

How can the Kinderdijk area meet the new requirements of the waterwet 2017 combined with improving the multi-layer safety concept in Kinderdijk related to dikes? Bron: Ridas

Possible adaptations

First, the most obvious connection which can be seen on the right. It’s the connection between the new water law 2017 and the other concepts. The New water law is the “main problem” in this project because everting needs to be improved because it doesn’t meet the new standards. Because they don’t meet the new standards problems occur on all these aspects. However, the law is made to provide safety to the Netherlands also for Kinderdijk. Better said is that the law is the solution to the problems in the area. which occur now and must be solved to guarantee safety. The dikes and banks can provide a lot of nature and recreation and tourism. With integrated purposes like roads and recreation area value will massively be increased. This will also work the other way around. Accessibility will increase tourism and can be combined with nature and flood protection. By doing this the circle will be closed. Creating a high value and sustainable region. This is possible by combining layer 2 & 3, if the right combination succeed, the problems with the dikes and shorelines will be solved. By layer 2 it is possible to build houses with steals. It is also possible to build dikes with special attention. For example adapt the dikes to the houses and be sure that the dikes are strong enough. But then it is possible that the dikes obstructs the view of the houses. It is possible to adapt dikes to the houses on such a way that it not obstructs the view. But then it costs more money to adapt the dikes to the surrounding area. This has also an advantage, because there are changes for dikes by adapting it to the surrounding area. The dikes can be used for other purposes. In addition it is also possible to get less of water in the area and replace it in other areas. These areas can store the water. For example more room for the river, water storage places or water squares and more green in the city. By these solutions is it important to keep the water quality in mind. Within layer 3 it is possible to do other thinks with the dikes, for example make them waterproof till a maximum level, and be sure that the evacuation is possible. For example make houses waterproof in the area and be sure that the people in the area can evacuate vertical, this means evacuate to the top of the houses. By combining all these layers it would be possible to get enough safety in the area. By implementing dikes that do not obstruct the view and implementing enough evacuation plans, is it possible that the area is safe enough. Bron: Ridas

Lessons learned

Contribution to flood resilience

For this area MLS, could mean a lot more. By looking at the knowledge about MLS in the Netherlands and the interview with the Province of Zuid-Holland (see appendix 7.1). By the research done on the MLS in the Netherlands found was that the opportunities and techniques are incredibly good. The Netherlands if the founder of MLS meaning the now all the ins and outs about the concept. However, by the interview with the province shown was that MLS is used way to less. The main conclusion is that layer 1 comes first and when this layer is complete other layers are looked at. The dikes must be fully build and meet the norms, when this is finished layer 2 is implemented by smart infrastructure and spatial planning. When this all is implemented layer 3 is finished. Layer 3 is by this approach bad. Recommended is using layer 2 and 3 in the very beginning when the problem still needs to be develop. By doing so smarter, sustainable and safer solution can be found.
