Uncontaminated sediment stored in confined disposal facilities (CDFs) represents a significant and often overlooked resource for marsh restoration. As a result of management practices in the second half of the twentieth century, many unnaturally high earthen structures occur adjacent to drowning saltmarshes in the United States. In this perspective article, we explore the potential for mining CDFs to provide the sediment necessary to restore and sustain at-risk saltmarshes. Using publicly available data from the US South Atlantic coast, we estimate that reclaiming sediment from existing CDFs could offset sea-level rise impacts by 2100 for 13% of South Atlantic marshes. While the potential benefit is substantial, scientific, planning and implementation hurdles are presented. These pitfalls include potential issues with sediment characterization, limited guidance on chemical evaluation to reduce environmental risks, construction complications due to soft soils and legal and financial considerations. Despite these barriers, we conclude with a path forward for researchers and practitioners to address the hurdles through dedicated case studies, adaptive management principles and stakeholder engagement.</p>","PeriodicalId":520999,"journal":{"name":"Cambridge prisms.

Using the Slapton Sands gravel barrier system, in Devon, as a case study, this article argues that repeated damage to the village of Torcross and the A379 road section that runs along the barrier illustrates a broader national cycle of escalating coastal risk despite decades of scientific understanding and strategic planning through Shoreline Management Plans (SMPs). Although none of the winter 2026 storms were individually extreme, their rapid succession, sequencing, and coincidence with spring tides caused substantial erosion, infrastructure collapse, and property damage, highlighting the cumulative threat of compound events. The case study exemplifies how defended coastlines and transport corridors can function as \"single points of failure,\" where disruption produces cascading social and economic consequences. While SMPs acknowledge the eventual need for \"Managed Realignment,\" implementation remains slow, politically contentious, and operationally vague, with policy often defaulting to short-term \"Hold the Line\" responses. This creates an adaptation deficit between national ambitions for resilience and practical action on the ground. We emphasise that transformational adaptation - including managed realignment, infrastructure relocation and community transition - requires coordinated national leadership, statutory support, a consistent approach and socially just frameworks that prioritise participation and fairness. Current local and national governance structures remain insufficient to meet the pace and scale of climate-driven coastal change. Torcross, like many vulnerable coastal communities, serves as an early warning of broader systemic failure: sea-level rise and intensifying coastal hazards will increasingly force the UK to confront difficult choices about protection, retreat and relocation.</p>","PeriodicalId":520999,"journal":{"name":"Cambridge prisms.

Understanding the magnitude, rate and trajectories of coastal transformation is critical for adaptation planning and hazard mitigation. This review synthesises current knowledge of coastal landform change across Southeast Asia (SEA), emphasising spatial and temporal variability driven by geological, climatic and anthropogenic boundary conditions. While globally sea levels are rising, tectonic deformation and vertical land motion dominate local trajectories, resulting in large spatial variability in relative sea-level rise (RSLR), offsetting SLR in uplifting areas and amplifying it in subsiding areas, where rates exceed 8 mm/yr, rivalling those of the Holocene marine transgression and surpassing global averages. The evolution of coastal landform types in response to boundary controls is examined. Paleo-reconstructions reveal that the Holocene transgression inundated ~2.3 million km² of the Sunda Shelf, fundamentally resetting the land-sea interface of SEA countries. Sea-level fall from the mid-Holocene highstand drove extensive coastal deposition, generating >100,000 km² of lowlands over the past 6,000 years, with progradation rates of 10¹-10² m/yr. These geologically young landscapes now face rapid, multidirectional change under contemporary forcing. Coastal change in SEA is complex, and rather than uniform erosion and inundation, the region exhibits a mosaic of responses, from stability to rapid progradation and island migration. Contemporary rates of change are comparable to those documented across the Holocene (10² m/yr), but are responding to a broader suite of drivers, including tectonic deformation, variable RSLR, extreme events and intense human activity. Attribution remains elusive, constrained by sparse spatial coverage, uneven representation of landform types and limited temporal resolution of data. Addressing these gaps requires comprehensive, site-specific studies of both geological and contemporary dynamics across all coastal typologies, supported by high-resolution monitoring and integrated modelling. Such efforts will provide the empirical foundation needed for informed coastal management and adaptation strategies in one of the world's most vulnerable regions.</p>","PeriodicalId":520999,"journal":{"name":"Cambridge prisms.

However, implementing large permanent closures can be difficult in many small-scale fisheries systems, where communities depend heavily on marine resources for their livelihoods and food security, and where issues of equity and access must be carefully considered. Around the world, many coastal communities instead rely on <i>temporary closures</i> - areas that open and close over time - to balance ecological recovery with ongoing use. Despite their prevalence and potential, these dynamic approaches remain conceptually underdeveloped compared to permanent marine-protected areas. This article calls for a reevaluation of marine management's prevailing focus on space by bringing <i>time</i> to the forefront of analysis. We introduce a framework that distinguishes two key temporal dimensions - duration and cyclicity - to clarify how different temporal designs shape ecological, social and governance outcomes. Within this framework, cyclicity captures how closures and openings alternate over time, including the relative balance between periods of access and closure (<i>i.e.</i>, the access ratio). Drawing on diverse examples where temporary management is implemented, this framework lays the groundwork for developing more formal theory and comparative evidence about how temporal strategies can align ecological recovery with livelihood dynamics in resource-dependent systems.</p>","PeriodicalId":520999,"journal":{"name":"Cambridge prisms.

We discuss the main advantages of TL, such as enabling model transferability of pretrained DL models from/to diverse coastal-estuarine systems and reducing computational time compared to physics-based models. These advantages can accelerate the deployment of flood prediction models in data-limited locations. We also discuss challenges and limitations that hinder accurate pattern recognition and propagation of EWLs from gauge (observation) stations to surrounding locations within model domains. These limitations include dependence on similarity in data distributions, overfitting the training data and both lag and hysteresis effects in the timing of peak water levels and flood dynamics. Lastly, we explain several misconceptions and challenges in current DL approaches that hinder EWL and spatiotemporal flood prediction, including training models exclusively on extreme conditions, assessing accuracy solely through goodness-of-fit metrics, and connecting the model's knowledge of input data with physical explanations of flood processes without an adequate context. We argue that these challenges can be addressed by prioritizing storm-relevant patterns of the input data features as well as embedding spatial propagation of EWLs in DL frameworks to mimic coastal-estuarine hydrodynamic models. Ultimately, progress toward generalizable model transferability relies on the modeler's ability to incorporate physical understanding in DL architectures, alongside continued advances in physics-informed machine learning models via soft or hard constraint approaches. There remains substantial work to establish guidelines and/or formal procedures to develop robust, interpretable, and generalizable DL models for spatiotemporal flood prediction, thereby supporting effective flood management, mitigation, and emergency preparedness.</p>","PeriodicalId":520999,"journal":{"name":"Cambridge prisms.
