Between 1994 and 2013, floods accounted for 43% of all recorded natural events, affecting nearly 2.5 billion people1. During exceptional years such as 1998 and 2010, total losses due to flooding have exceeded $40 billion. In the coming decades with climate change, urbanization, and demographic growth, the impact of coastal, fluvial, and pluvial flooding is expected to increase significantly. Effective flood risk management is critical to protect people and their livelihoods from flooding and to limit future losses. Nature- based measures and their ability to address flood risk are receiving increasing attention. Failing sea wall 6 Implementing nature-based flood protection I Principles and implementation guidance Until recently, most flood risk management involved implemented on an ad-hoc basis. While there have conventional engineering measures. These measures are been significant advances in the design and testing sometimes referred to as “hard” engineering or “gray” protocols for ecosystems and their role in risk mitigation, infrastructure. Examples include building embankments, these solutions have yet to be fully evaluated and dams, levees, and channels to control flooding. Recently standardized. As a result, some nature-based projects the concept of “nature-based solutions”, “ecosystem- for climate adaptation and disaster risk reduction have based adaptation”, “eco-DRR” or “green infrastructure” not been designed properly, leading to ineffective and has emerged as a good alternative or complement to unsustainable results. As is the case for engineering traditional gray approaches. Nature-based solutions solutions, there is no ‘one size fits all’ approach given make use of natural processes and ecosystem services that climatic, ecological, and hazard characteristics are for functional purposes, such as decreasing flood risk variable and are often poorly understood. However, or improving water quality. These interventions can be the sector of traditional infrastructure has a long completely “green” (i.e. consisting of only ecosystem history in which they have fully developed protocols elements) or “hybrid” (i.e. a combination of ecosystem and standards, whereas nature-based solutions are elements and hard engineering approaches). emerging approaches that

  • PUB Commences Coastal Protection Study at City-East Coast
    PUB commences coastal protection study at City-East Coast First site-specific study key to developing a flood resilient master plan to protect Singapore’s south-eastern coastlines from sea-level rise Singapore, 18 May 2021 – National Water Agency PUB will commence a site-specific study along Singapore’s City-East Coast, looking into possible solutions to protect it from the threat of rising seas caused by climate change. This is the first of a series of planned studies for different parts of Singapore’s coastline to be progressively carried out over the next few years, and are a key plank in Singapore’s long-term coastal protection plans. 2 The study covers 57.8 km of the coastline, across three areas (see Annex A for detailed infographic showing the scope of study) – Changi, the East Coast-Marina stretch and part of the Greater Southern Waterfront district. This section of the coastline had been identified to be more vulnerable and critical based on factors such as the potential impact of a flood event, criticality of assets (e.g. airports, economic and industrial districts) and opportunities to dovetail with upcoming developments. 3 The study will take around four years to complete, and will include work such as literature review to glean international best practices, collecting site data to support design works, formulating adaptation measures and pathways and developing the designs of solutions to mitigate flood risks. 4 Ms Hazel Khoo, Director of PUB’s Coastal Protection Department, said, “When PUB was appointed national coastal protection agency in April 2020, this study was earmarked as a significant milestone in our mission to prepare Singapore for the impacts of sea-level rise.

The Proceedings is divided into seven parts: Keynote; Waves; Swash, Nearshore Currents, and Long Waves; Sediment Transport and Morphology; Coastal Structures; Coastal Management, Environment, and Risk, and Posters. The individual papers cover a broad range of topics including theory, numerical and physical modeling, field measurements, case studies, design, and management. These papers provide engineers, scientists, and planners state-of-the-art information on coastal engineering and coastal processes. Foreword The 32nd International Conference on Coastal Engineering (ICCE 2010) was held in Shanghai, China, 30 June to 5 July of 2010. The Local Organizing Committee, led by Xie Shileng, Ge Jiufeng, Dou Xiping, and Zuo Qihua, is acknowledged for their dedicated preparation over many years that led to a successful conference with broad participation. Six-hundred attendees from 38 countries gathered at the Shanghai International Convention Center to discuss research and applications in coastal engineering. The papers contained in this Proceedings cover a wide range of topics including waves; swash, nearshore currents, and long waves; coastal management, risk, and environmental restoration; sediment transport and morphology; and coastal structures. The authors have provided state-of-the-art contributions, and this volume could not be produced without their commitment to solving coastal engineering challenges.

Voorendt, Delft University of Technology published by Bee’s Books, Amsterdam series: Delta Technology, Design & Governance Cover page: graph from the Delta report, part 1 (1960) PREFACE This report is part of my research on the ’structural evaluation of multifunctional flood defences’. The research is part of the programme on ’integral and sustainable design of multifunctional flood defences’ which is supported by the Dutch Technol- ogy Foundation STW, which is part of the Netherlands Organisation for Scientific Re- search (NWO), and is partly funded by the Ministry of Economic Affairs. This pro- gramme is one of the ’Perspective’ programmes that are organised within consortia of research institutes and users. The research programme consists of several projects in which various aspects of mul- tifunctional flood defences are studied. These include technical aspects (strengths and loads), safety philosophy, governance, architecture and financial aspects. For details of the programme, one is referred to the project proposal (see the information on www.flooddefences.org).

  • An Interdisciplinary Approach to Understanding Sandy Coasts
    NatureCoast: an interdisciplinary approach to understanding sandy coasts Timothy Price, VU University Amsterdam, [email protected] Arjen Luijendijk, Delft University of Technology, [email protected] Vera Vikolainen, University of Twente, [email protected] Jaap van Thiel de Vries, Boskalis, [email protected] Marcel Stive, Delft University of Technology, [email protected] Sandy coasts are highly dynamic environments, governed by interactions of various physical, biological and societal processes. Waves, currents and wind, for example, are important environmental drivers for coastal morphodynamics. At the same time, these drivers affect ecological processes, with possible feedbacks to groundwater levels, nutrient dynamics and dune morphology. Besides these natural dynamics that constitute the coastal ecosystem, humans may influence this system, driven by the benefits they wish to obtain from the system and the societal dynamics involved. A common intervention in coastal systems is the nourishment of sand, of which the Sand Motor on the Delfland coast, The Netherlands, is an example with an unprecedented volume of 21.5 Mm3. Our aim is to improve our predictive understanding of this type of sandy nourishment as an ecosystem, in order to apply it elsewhere. With our research programme NatureCoast we have seized the opportunity to gather strategically important interdisciplinary knowledge from the Sand Motor, which forms a unique full-scale experiment. The programme includes 12 PhD projects, in which the key morphological, hydrological, geochemical, ecological and societal processes that govern the evolution and acceptability of this type of nourishments are studied (Figure 1). The innovative aspect of our approach lies in the integration of these research projects through interdisciplinary research questions.
