The usability of the sand motor concept
This report describes the usability of the Sand Motor concept for managing the Dutch coast as an alternative to regular sand nourishments. The evaluation of the usability is based on experience with the Sand Motor pilot project before, during and after the construction in 2011 and by making an inventory of the functions and values along the Dutch coast in the present situation and the coming decades.
Annual review Deltares 2011
Adaptive water management for delta regions : towards GREEN Water Defense in East Asia
GREEN Water Defense is an innovation to traditional ways of flood protection. It uses ecosystem services to mitigate the flood hazard. The report describes best practices from the Netherlands, the USA and other OECD countries The report also identified good opportunities for applying the concept in the Mekong Delta, Vietnam and the Jakarta metropolitan area, Indonesia.
A framework for sandy strategy development, with a quick scan for (co-)financing potential
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.
R&D annual report Deltares 2010
One of the Deltares aims is to make Research and Development results more accessible to the public and the private sector. The R&D Highlights report is one step towards that goal. The chapters of the Highlights report follow the structure of the five social issues that are central to the Deltares mission.
Building the Netherlands climate proof : urban areas : a contribution to the study “Opportunities for climate adaptation in the Netherlands” of the Netherlands Environmental Assessment Agency
Vulnerability analysis of Dutch urban areas for flooding, drought and heat stress. Adaptive capacity and cost-efficient adaptation measures. Policy development.
Ecosystem services of the groundwater and the subsurface : filling the knowledge gap
In densely populated areas, the use of groundwater and the subsurface for functions such as groundwater extraction, aquifer thermal energy storage and infrastructure is increasing. This results in a need for subsurface spatial planning and careful consideration of the use of groundwater for several (economic) activities. Since 2013, in the Netherlands special attention is given to ecosystem services (ES) of the groundwater and subsurface in order to assess how human activities make use of ES and influence ES. A technical assessment framework for the sustainable use of the groundwater and subsurface was developed based on the ES concept. In this paper, the goals of the framework are described, followed by the identified eleven ES and the thirty-one human activities influencing the ES and the relations between both. An example of elements in the framework is presented and the practical application of ES in policy is described.
Towards practical implementation of the ecosystem services (ES) concept in transboundary water management
This report includes the result of a pilot study to assess the practical application and value of an ecosystem services approachin regional/local water management in a transboundary study area.
Lessons of past disasters and preparedness actions to cope with future hydrological extreme events in the Netherlands
The Netherlands, being a low-lying delta of the rivers Rhine, Meuse and Scheldt, have grappled for centuries in coping with water-related disasters: floods originating from both storm surges and high river discharges. Projected climate change scenarios learned the country to prepare for even more frequent and more intense extreme events. We realized the need for new solutions: automatically heightening the levees to protect against flooding was no longer a sustainable solution. We had to change the system we worked with for centuries and broaden its goals. The Netherlands revisited their safety standards for protection against flooding, now incorporating a risk-based approach. We introduced nature-based solutions like “Room for the River” to enable higher river discharges and the “Sand Engine” for beach nourishment to complement traditional engineering for protective disaster resilient infrastructure. The Netherlands embraced system thinking to future proof the country, and we incorporated cultural and ecological values into adaptive decision making. The Netherlands has proven it can shift the fundamentals of its strategy to prepare for a changing climate. Essentially, we have addressed the synergies between the agendas of water-related disaster risk reduction and climate adaptation in a coherent way, both of which are essential in reaching the integrated goals of the nation’s long-term vision for sustainable development.
Development plan water quality modelling framework
As a first step in the designing of a plan for the WQMF, the contours and the building blocksof the framework have been defined and schematized in a so-called roadmap. This roadmapdepicts the coherence of the building blocks and the planned development over time. Themap is to be used as a planning tool.
