Safe and multifunctional urban levees (HSRR06)

The goal of this research was development of knowledge and concepts about combining spatial functions with flood protection within a densely urbanized area. Next to the reconnaissance of technical solutions the research focused on process innovations regarding this topic. What does multifunctional use of flood protection mean for legislation, management, responsibilities, existing spatial planning procedures and partnerships within the planning process?

The research resulted in:

    1. General solutions for three locations in Rotterdam, based on which generic solutions for comparable situations in the Netherlands were identified
    2. A strategy applicable for the Rotterdam region
    3. Identification of remaining research questions, necessary adjustments in the legislation and/or the roles and process

As part of the survey, four strategies were investigated that could be pursued in order to develop safe, future-proof, multifunctional urban levees. These strategies were the subject of further research in the four different case study locations:

    • The levee as area transformer (case study: Nieuw Mathenesse)
    • The levee as urban public domain (case study: Boompjes)
    • The levee as a basis for area development (case study: Stadionpark)
    • The levee as an integrated structure (case study: Brielselaan)

The outcome of the research led to the following conclusions:

    1. Combined water defence design enables light urban use 
    2. Overdesigning is a promising strategy for intensive urban use
    3. Integrated solutions are feasible, but only in dire need of space and when relevant from a social perspective
    4. The main key to success is process innovation
