“…For example, pathways for the Danube and Ebro deltas first consider green protection with reeds combined with raising the land via strategic sediment measures, with a later option of set-back lines within a planned realignment of the coastline [50]. Along parts of the coast in the UK (e.g., The Wash), Germany (e.g., Langeoog Island), and the Netherlands (e.g., Westerschelde), managed realignment is implemented to restore saltMarshes and to aid coastal defence [51][52][53].…”

Adaptation to coastal flood risk is hampered by high uncertainty in the rate and magnitude of sea-level rise. Subsequently, adaptation decisions carry strong risks of under-or over-investment, and could lead to costly retrofitting or unnecessary high margins. To better allocate resources timely and effectively, and achieve long-term sustainability, planners could utilise adaptation pathways, revealing the path-dependencies of adaptation options. This helps to identify low-regret short-term decisions that preserve options in an uncertain future, while monitoring to detect signals to adapt. A major barrier to the application of adaptation pathways is limited experience. To facilitate this, here we generalize this pathways approach for six common coastal archetypes, resulting in generic pathways suitable to be adjusted to local conditions. This provides a much richer analysis of coastal adaptation than provided by any previous analysis, by assessing the solution space and options over time for a variety of coastal regions. Based on this analysis, we find that the number of adaptation options declines while sea-level rises. For some archetypes, it becomes clear that long-term thinking is needed now, about if, how and when to move to transformative options, such as planned retreat, which may presently not be considered or acceptable. Our analysis further shows that coastal adaptation needs to start earlier than anticipated, especially given time required for local debate and choice and to implement measures.

Coastal habitats are highly threatened ecosystems that are sensitive to complex sets of natural and human drivers. Europe's coastal habitats are protected from damage due to human activity by the EU Habitats Directive, and are required to be mapped within flood risk assessments by the EU Floods Directive. Ecological vulnerability and risk assessments are a common way of assessing the impacts on these habitats due to human and natural drivers. Coastal flood risk assessments therefore often include assessments of the vulnerability of coastal habitats. Flood risk assessments also evaluate, where relevant, the mitigation services provided by coastal habitats. The two aspects of coastal habitats -their flood mitigation service and their ecological vulnerability are strongly correlated; however these are usually treated separately within flood risk assessments. One of the goals of the EU THESEUS project is the integrated consideration of coastal habitats within flood risk assessments. This paper investigates the integration within flood risk assessments of the two aspects of coastal habitats using the 2D SPR conceptual model. The construction of the model is first illustrated by application to a generic study site. The model is then applied to a casestudy where data on habitat elevations and vulnerabilities to flood events have been collected. The model provides a unique and robust means of combining information on ecological vulnerability indices for different habitat associations with information on their distribution and spatial relationships within the coastal floodplain. Used in conjunction with information on habitat vulnerability indices, the conceptual model serves as a powerful tool for integrated and structured consideration of coastal habitats within flood risk assessments.

“…However, new information on the risks of functions is becoming increasingly available through ongoing research (Aguilar-López et al, 2018;Vuik et al, 2018). Furthermore, new techniques are being employed to continuously monitor the dikes in detail (Hanssen and Van Leijen, 2008;Herle et al, 2016) while advances in remote sensing allow for closer monitoring of the state of foreshores (Niedermeier et al, 2005;Friess et al, 2012). As a result, a probabilistic approach towards functions can capitalise on these advances by updating the previously assumed risks in assessments with observations of the actual performance of MFFDs over time.…”

Abstract. Multifunctional use of flood defences is often seen as a disadvantage for flood protection. Safety assessments of multifunctional dikes only require functions do not negatively affect safety but leave potential synergies untapped. This study synthesizes the new probabilistic approaches to evaluate the safety of multifunctional flood defences employed in the Netherlands after the introduction of the new Water Act and explores how this affects the assessed risk of flooding. While a traditional conservative approach does lead to safe assessments, a probabilistic approach assesses a higher protection level of the dike. Positive contributions of functions to safety can be included in a probabilistic approach even when in a critical state there is a negative contribution to safety. In a probabilistic approach the probability of such scenarios is made explicit. Multifunctional flood defences thereby are more safe than is expected from conservative assessments only.
