The CoasTER geographic database provides erosion relevant characteristics for Europe’s coastal floodplains. It builds on earlier erosion research and includes a coastal geomorphological typology incorporating modification in the form of hard engineering and infrastructure. Analysis shows 27 % of coastal floodplains have shown significant erosion over the last 40 years. Nearly 3,500 km will require additional or new management to protect developed areas and infrastructure if the trend continues.

We used a novel database of simulated tropical cyclone tracks to explore whether typhoon-induced storm surges present a future flood risk to low-lying coastal communities around the South China Sea. We found that future climate change is likely to change tropical cyclone behaviour to an extent that this increases the severity and frequency of storm surges to Vietnam, southern China, and Thailand. Consequently, coastal flood defences need to be reviewed for resilience against this future hazard.

Relative sea level in Venice rose by about 2.5 mm/year in the past 150 years due to the combined effect of subsidence and mean sea-level rise. We estimate the likely range of mean sea-level rise in Venice by 2100 due to climate changes to be between about 10 and 110 cm, with an improbable yet possible high-end scenario of about 170 cm. Projections of subsidence are not available, but historical evidence demonstrates that they can increase the hazard posed by climatically induced sea-level rise.

In this review we describe the factors leading to the extreme water heights producing the floods of Venice. We discuss the different contributions, their relative importance, and the resulting compound events. We highlight the role of relative sea level rise and the observed past and very likely future increase in extreme water heights, showing that they might be up to 160 % higher at the end of the 21st century than presently.

The city of Venice relies crucially on a good storm surge forecast to protect its population and cultural heritage. In this paper, we provide a state-of-the-art review of storm surge forecasting, starting from examples in Europe and focusing on the Adriatic Sea and the Lagoon of Venice. We discuss the physics of storm surge, as well as the particular aspects of Venice and new techniques in storm surge modeling. We also give recommendations on what a future forecasting system should look like.

Venice is an iconic place, and a paradigm of huge historical and cultural value is at risk. The threat posed by floods has dramatically increased in recent decades and is expected to continue to grow – and even accelerate – through this century. There is a need to better understand the future evolution of the relative sea level and its extremes and to develop adaptive planning strategies appropriate for present uncertainty, which might not be substantially reduced in the near future.

In coastal regions, floods can arise through concurrent drivers, such as precipitation, river discharge, storm surge, and waves, which exacerbate the impact. In this study, we identify hotspots of compound flooding along the southern coast of the North Atlantic Ocean and the northern coast of the Mediterranean Sea. This regional assessment can be considered a screening tool for coastal management that provides information about which areas are more predisposed to experience compound flooding.

Flooding can arise from multiple sources, including waves, extreme sea levels, rivers, and severe rainfall. When two or more sources combine, the consequences can be greatly multiplied. We find the potential for the joint occurrence of extreme sea levels and river discharge to be greater on the western coast of the UK compared to the eastern coast. This is due to the weather conditions generating each flood source around the UK. These results will help increase our flood forecasting ability.

This paper evaluates the effect of surge water level reduction due to land surface characteristics when assessing flood impacts at global scales. Our results show that uncertainties due to not accounting for water attenuation are of similar magnitude to the uncertainties regarding the total amount of sea-level rise expected by 2100, thus highlighting the need for better understanding of the spatial and temporal variation of water levels across floodplains.

Short summary
Global assessments of coastal flooding are based on the assumption that water propagation follows a
bathtubpattern across the floodplain. Using a global model we find that this assumption can lead to overestimation of impacts, with an uncertainty range that can be of equal magnitude to uncertainties related to future sea-level rise. Our results highlight the importance of improving the representation of the spatial/temporal variation of water levels across floodplains of different landcover.

Recent coastal floods in the USA have highlighted a lack of resilience in poor communities. By researching successes from Bangladesh and Cuba, this paper details how lessons from these countries can reduce the vulnerability of less well-off or isolated American citizens to future coastal storm surges. The relevance of the lessons learnt from Cuba and Bangladesh to the USA was assessed. Transferable lessons include the importance of volunteerism and education in developing a “culture of safety”.

CoastalME is a generic modelling environment to simulate coastal landscape evolution on spatial scales of kms to tens of kms, over decadal to centennial timescales. The novelty is that it simulates coastal morphology evolution as a set of dynamically linked raster and geometrical objects. Geometrical objects are derived from the raster structure providing a library of coastal elements (e.g. shoreline) that are conventionally used for modelling coastal behaviour on the timescales of interest.

A criterion to categorise climate change adaptation frameworks is presented denoting characteristics of three key frameworks established in the literature: scenario–led, decision-centric and vulnerability–led. Applying the criterion, the usability of frameworks is examined in coastal Suffolk. Results indicate adaptation frameworks established in the literature are not utilised in isolation in everyday practice. In reality, hybrid approaches are utilised to overcome aspects of framework weakness.

This work deepens the understanding of how perceived heat stress, human vulnerability (e.g. age, income) and adaptive capacities (e.g. green, shaded spaces) are coupled with urban structures. The results show that perceived heat stress decreases with distance from the urban center, however, human vulnerability and adaptive capacities depend more strongly on inner variations and differences between urban structures. Planning policies and adaptation strategies should account for these differences.

Many households in Vietnam depend on revenue from micro-businesses (shop houses). However, losses caused by regular flooding are not modelled. Business turnover, building age, and water depth were found to be the main drivers of flood losses of micro-businesses. We built and validated probabilistic models (non-parametric Bayesian networks) that estimate flood losses of micro-businesses. The results help with flood risk management and adaption decision making for micro-businesses.

Our research explores how social media can help understand public responses to floods, focusing on the 2021 western European flood. We found that discussions varied by location and flood impact: in-disaster concerns were more common in severely affected upstream areas, while post-disaster topics dominated downstream. Findings show the potential of social media for improving disaster coordination along cross-border rivers in time-sensitive situations.

In post-disaster reconstruction, emphasis should be placed on critical and sensitive infrastructures. In Germany, as in other countries, sensitive infrastructures have not yet been focused on; therefore, we developed a method for determining the risk that sensitive infrastructures are facing in the context of riverine and pluvial flooding. The easy-to-use assessment framework can be applied to various sensitive infrastructures, e.g., to qualify and accelerate decisions in the reconstruction process.

This study measures the direct effects of droughts in association with other extreme weather events on agriculture in Germany at the district level. Using a statistical yield model, we quantify the direct damage of extremes on crop yields and farm revenue. Extreme events during drought cause an average annual damage of EUR 781 million, accounting for 45 % of reported revenue losses. The insights herein can help develop better strategies for managing and mitigating the effects of future climate extremes.

Cities in coastal and delta areas need effective engineering techniques to counteract subsidence and its damage. This paper presents a framework for choosing these techniques using a decision tree and four performance parameters. This procedure was tested on various cases representative of different scenarios. This demonstrated the potential of this method for initial screenings of techniques which site-specific assessments should always follow.

This study explores how communities can better protect people's lives and health during floods. By looking at 66 communities in seven countries, we found that strong social ties and preparedness before disasters helped reduce injuries and deaths. However, some environmental efforts didn't show clear health benefits, especially in degraded areas. Our research highlights how early planning and strong local networks can make a real difference during crises.

Households play a crucial role in climate adaptation efforts. Yet, households require capacities to implement measures. We explore which capacities enable German households to adapt to flooding. Our results indicate that flood-related capacities such as risk perception, responsibility appraisal, and motivation are pivotal, whereas financial assets are secondary. Enhancing these specific capacities, e.g. through collaborations between households and municipalities, could promote local adaptation.

While the first flood warning with evacuation instructions is identified as timely, its lack of detail and effectiveness resulted in low public risk awareness. Better dissemination of warnings and improved risk perception and preparedness among the population could reduce casualties by up to 80 %.

This study proposes a response-bias-tolerant methodology for constructing production capacity loss rate (PCLR) curves, which addresses response bias in extreme flood scenarios and considers the distribution characteristics of PCLR under different damage states. The core value of this study is to provide a competing and promising input in economic modeling, such as input-output and computable general equilibrium models.

Our research presents a new method for determining warning levels for any hazard. Using risk matrices, our framework addresses issues found in other approaches. We provide examples to demonstrate how the approach works. A powerful method for evaluating warning accuracy is given, allowing for a cycle of continuous improvement in warning services. This research is relevant to a broad audience, from those who develop forecast systems to practitioners who issue or communicate warnings.

Our study explores how farmers in India's Bhima basin respond to consecutive droughts. We simulated farmers' individual choices – like changing crops or digging wells – and their effects on profits, yields, and water resources. Results show these adaptations, while improving incomes, ultimately increase drought vulnerability and damage. Such insights emphasize the need for alternative adaptations and highlight the value of socio-hydrological models in shaping policies to lessen drought impacts.

Environmental assets are crucial to sustaining and fulfilling life on Earth via ecosystem services (ESs). Studying their flood risk is thus seminal, in addition to being required by several norms. However, this field is not yet adequately developed. We studied the exposure component of flood risk and developed an evaluating methodology based on the ESs provided by environmental assets to discern assets and areas that are more important than others with metrics suitable to large-scale studies.

Natural hazards like earthquakes often trigger other disasters, such as landslides, creating complex chains of impacts. We developed a risk model using a mathematical approach called hypergraphs to efficiently measure the impact of interconnected hazards. We showed that it can predict broad patterns of damage to buildings and roads from the 2015 Nepal earthquake. The model's efficiency allows it to generate multiple disaster scenarios, even at a national scale, to support preparedness plans.

This study analyzes flood exposure in Rotterdam's unembanked areas from 1970 to 2150, exploring the interplay between rising sea levels, urban development, and flood protection measures. Without measures, flood exposure will increase, especially after 2100. The Maeslant storm surge barrier had the most impact on flood exposure, followed by urban development and sea level rise. Varied exposure levels across neighborhoods suggest the need for localized adaptation strategies.

There is a global need for insuring green economy assets against natural hazard events. But their complexity and low exposure history mean the data required for vulnerability evaluation by the insurance industry are scarce. A systematic literature review is conducted in this study to determine the suitability of current published literature for this purpose. Knowledge gaps are charted, and a representative asset–hazard taxonomy is proposed to guide future quantitative research.

Droughts can impact agriculture and regional economies, and their severity is rising with climate change. Our research introduces a new system, the Australian Agricultural Drought Indicators (AADI), which measures droughts based on their effects on crops, livestock, and farm profits rather than traditional weather metrics. Using climate data and modelling, AADI predicts drought impacts more accurately, helping policymakers prepare and respond to financial and social challenges during droughts.

Several sources of uncertainty affect flood risk estimation for reliable assessment for investment, insurance and risk management. Here, we consider the uncertainty of large-scale flood hazard modeling, providing a range of risk values that show significant variability depending on geomorphic factors and land use types. This allows for identifying the critical points where single-value estimates may underestimate the risk and the areas of vulnerability for prioritizing risk reduction efforts.

This study shows migration patterns to be a critical factor in seismic fatalities. Analyzing the Chi-Chi earthquake in Taiwan, we find that lower income and a higher indigenous population at migrants' origins are correlated with higher fatalities at their destinations. This underscores the need for affordable and safe housing on the outskirts of megacities, where migrants from lower-income and historically marginalized groups are more likely to reside due to precarious employment conditions.

As sea levels rise, coastal areas will experience more frequent flooding, and salt water will start seeping into the soil, which is a serious issue for farmers who rely on good soil quality for their crops. Here, we studied coastal Mozambique to understand the risks from sea level rise and flooding by looking at how salt intrusion affects farming and how floods damage buildings. We find that 15 %–21 % of coastal households will adapt and 13 %–20 % will migrate to inland areas in the future.

The Central Volcanic Zone of the Andes (CVZA) spans four countries with 59 volcanoes. We identify those with the most intense and frequent eruptions and the highest potential impact that require risk mitigation actions. Using multiple risk factors, we encourage the use of regional volcanic risk assessments to analyse the level of preparedness especially of transboundary volcanoes. We hope that our work will motivate further collaborative studies and promote cooperation between CVZA countries.

Check dams, terraces, and trees on steep basins serve to retain sediments, thereby protecting urbanized alluvial fan canals and levees from flooding. However, their effectiveness gradually decreases over time due to sedimentation and aging, which may lead to catastrophic breaching floods. To enhance urban resilience, we propose preserving natural mountain basins and allocating 20–30 % of the alluvial fan for channel migration and sediment deposition corridors.

Our simulations suggest that increased drought frequencies lead to a drastic reduction in biomass in pine monoculture and mixed forest. Mixed forest eventually recovered, as long as drought frequencies was not too high. The higher resilience of mixed forests was due to higher adaptive capacity. After adaptation mixed forests were mainly composed of smaller, broad-leaved trees with higher wood density and slower growth.This would have strong implications for forestry and other ecosystem services.

We evaluate the influence of urban processes on the impacts of the 2023 disaster that hit the North Coast of São Paulo, Brazil. The impacts of the disaster were largely associated with rapid urban expansion over the last 3 decades, with a recent occupation of risky areas. Moreover, lower-income neighborhoods were considerably more severely impacted, which evidences their increased exposure to such events. These results highlight the strong association between disaster risk and urban poverty.

Utilizing a survey including respondents from seven societal sectors, the role of water dependency for drought vulnerability was explored. Differences were found in the perceived impact of vulnerability factors on drought risk in relation to water dependency (i.e., dependency on either soil moisture, or groundwater and surface water). The results highlight the importance of accounting for water dependency, and to clearly define the drought hazard, in drought vulnerability or risk assessments.

Iranian insurers have been offering earthquake coverage since the 1990s. However, despite international best practices, they still do not use modern methods for risk pricing and management. As such, they seem to be accumulating seismic risk over time. This paper examines the viability of this market in Iran by comparing the local market practices with international best practices in earthquake risk pricing (catastrophe modeling) and insurance risk management (European Solvency II regime).

Despite droughts are deeply intertwined within sociohydrological systems, traditional top-down approaches often ignore those directly affected. By integrating insights from five research fields, we present a framework to guide the co-creation of knowledge for drought impact assessment. Emphasizing social dynamics and power imbalances, the framework guides a more inclusive approach to drought assessment and adaptation.

Short summary
Using census data, historic maps and hydrodynamic modelling, this paper presents a methodology for assessing how the exposure of people to flooding has changed over the last 200 years at the local level in the UK. The method is applied to two case studies at Portsea and Hayling Islands in the UK's Solent region. The analysis shows that for the case studies, population rise has, to date, had a much greater influence on exposure than sea level rise.
