Modelling the combined impact of sea level rise, land subsidence, and tropical cyclones in compound flooding of coastal cities

Low-lying coastal areas are threatened worldwide by compound flooding effects, including sea-level rise (SLR), frequent tropical cyclones (TCs), and accelerated land subsidence (LS). Compound flooding results in a negative effect, creating challenges for decision-making and coastal management for sustainable urban development. To comprehend...

Collaborative Design Strategy for Flood Risk Reduction in East Uganda

Background:<br/>Climate change is affecting Uganda through the worsening floods that happen on a yearly basis. These disasters are claiming the lives and livelihoods of local communities, which lead to more challenges such as economic consequences and forced migration. Immediately after hazards like floods strike, local communities are always...

Development of an Efficient Modelling Approach to Support Economically and Socially Acceptable Flood Risk Reduction in Coastal Cities: Can Tho City, Mekong Delta, Vietnam

Flooding is one of the most frequently occurring and damaging natural disasters worldwide. Quantitative flood risk management (FRM) in the modern context demands statistically robust approaches (e.g. probabilistic) due to the need to deal with complex uncertainties. However, probabilistic estimates often involve ensemble 2D hydraulic model runs...

Planning and Suitability Assessment of Large-scale Nature-based Solutions for Flood-risk Reduction

Adverse effects of climate change are increasing around the world and the floods are posing significant challenges for water managers. With climate projections showing increased risks of storms and extreme precipitation, the use of traditional measures alone is no longer an option. Nature-Based Solutions (NBS) offer a suitable alternative to...

An integrated framework of coastal flood modelling under the failures of sea dikes: a case study in Shanghai

Climate change leads to sea level rise worldwide, as well as increases in the intensity and frequency of tropical cyclones (TCs). Storm surge induced by TC’s, together with spring tides, threatens to cause failure of flood defenses, resulting in massive flooding in low-lying coastal areas. However, limited research has been done on the...

Detection of Disaster-Prone Vernacular Heritage Sites at District Scale: The Case of Fındıklı in Rize, Turkey

The district of Fındıklı in the Northeast city of Rize in Turkey is environmentally and culturally rich with its rural, built, and natural heritage. The city of Rize has been experiencing more frequent and severe rainfall, flooding, and landslides in the last decade. River flooding along the coast and in the center of the city is destroying...

Hard or soft flood adaptation? Advantages of a hybrid strategy for Shanghai

Flood risk is expected to increase in coastal cities, particularly in Asian megacities such as Shanghai. This paper presents an integrated modeling framework to simulate changes in the flood risk in Shanghai and provide a cost-benefit analysis of multiple adaptation strategies used to reduce risk. The results show that the potential flood...

Data Reduction Techniques of Coral Reef Morphology and Hydrodynamics for use in Wave Runup Prediction

Many tropical, coral reef-lined coasts, are low-lying with elevations less than five meters above mean sea level. Climate-change-driven sea level rise, coral reef decay and changes in (storm) wave climate will lead to greater chance and impacts of wave-driven flooding, posing a heavy threat to these coastal communities. Early warning systems ...

Optimization of flood safety levels: Case study for unembanked areas in the Port of Rotterdam

How to evaluate a monitoring system for adaptive policies: criteria for signposts selection and their model-based evaluation

Adaptive policies have emerged as a valuable strategy for dealing with uncertainties by recognising the capacity of systems to adapt over time to new circumstances and surprises. The efficacy of adaptive policies hinges on detecting on-going change and ensuring that actions are indeed taken if and when necessary. This is operationalised by...

Assessing the capacity of adaptive policy pathways to adapt on time by mapping trigger values to their outcomes

Climate change raises serious concerns for policymakers that want to ensure the success of long-term policies. To guarantee satisfactory decisions in the face of deep uncertainties, adaptive policy pathways might be used. Adaptive policy pathways are designed to take actions according to how the future will actually unfold. In adaptive...

Collaborative spatial planning in the face of flood risk in delta cities: A policy framing perspective

Integration of flood risk in spatial planning is increasingly seen as a way to enhance cities’ resilience to the growing flood hazards, albeit its operationalisation remains challenging. This study aims to explain the reasons for this difficulty through the case study of Guangzhou, a Chinese delta city that is highly vulnerable to coastal,...

Landscapes of Resistance: documenting the frontline of Climate Change in Louisiana

Louisiana, USA, operates as an oilscape, sacrificing its landscape in pursuit of economic prosperity through the oil and gas industry. Combined with sea level rise, this has resulted in continuous land loss since the fifties, making the Louisiana coast one of the fastest declining in the world. As a consequence, many communities are living on...

Working Waterfront Newtown Creek - Adaptive multi-layer flood protection on brownfield opportunity areas

For 400 years New York has a turbulent interaction with its surrounding waters. It embraced, tamed, neglected and rediscovered the waterfront which made its greatness possible. Hurricane Sandy brought in a new complexity for New York and its relationship with the waterfront. The storm reminded the city where it is located and paid a high price...

Long-term strategies for flood risk management: Scenario definition and strategic alternative design

Flood risk management requires policy making for a relatively far and largely unknown future. Task 14 of Theme 2 in FLOODsite aims to provide methodological guidance on how to perform the design/development of long term strategic alternatives for flood risk management and how to assess their performance in different future scenarios. To begin...
