The Sand Motor is a partly emerged mega-nourishment at the Delfland coast in the Netherlands. It is an example of a Building with Nature (BwN) solution using natural processes to fulfil multi-functional purposes in coastal management, such as coastal protection, beach recreation and nature development. EcoShape wishes to explore the opportunities for sandy strategies like the sand motor in an international context. To this end, a framework for the development of sandy strategies is developed by a consortium of Deltares, Royal Haskoning DHV and Witteveen+Bos. This framework aims to assist the BwN community to quickly assess whether sandy strategies are feasible and beneficial for projects both in the Netherlands and abroad. The framework consists of five main steps to assess the feasibility of a project. It starts with the context and scope of the project at hand, followed by a system analysis, design and evaluation of strategies and, finally, an assessment of the (co-)financing potential. The framework explicitly accounts for (the capturing of potential) benefits resulting from the strategies from the early stages of the design process in order to increase the potential for (co-)financing for their implementation. This report presents the framework that has been developed, including guidelines and tools for its application in practice.
