However, these areas are experiencing frequent storm surges and coastal flooding which has caused US$ 76.74 billion direct economic losses and 7138 fatalities from 1989 to 2014. Given China’s rapid urbanisation and global climate change, it is crucial to identify what the future impacts of coastal flooding in China will be, and how these trends may alter under changing climatic conditions (e.g. sea level rise) and anthropogenic drivers (e.g. enhanced subsidence), and what adaptation can be undertaken to reduce possible risks. Presently, there is no combined national and regional assessment of future flooding, damage and adaptation costs due to sea-level rise in China. This presentation presents impacts and costs of coastal change in China, taking into account a wide range of uncertainties in socioeconomic development, sea-level rise, local subsidence/protection data, and adaptation strategies. Quantitatively assessed damage and adaptation costs of coastal flooding in China are assessedv using the Dynamic Interactive Vulnerability Assessment (DIVA) modelling framework and a range of RCPs (Representative Concentration Pathways, RCPs) climate scenarios representing future sea-level rise, and SSPs (Shared Socio-economic reference Pathways, SSPs) representing socio-economic change. These are combined with new data on coastal type, subsidence and protection standards, plus future subsidence control plan and protection plan from government. Preliminary results show that 25-123 cm of relative sea-level rise is projected in 2100. With subsidence, 28.2 million population are expected to be flooded annually under a 100-year flood event in 2100, with 81,000 km2 areas and US$ 7.19 billion assets at risk. Furthermore, due to human-induced subsidence, flood risk is most serious in coastal mega-cites, e.g. Shanghai and Tianjin. This study emphasises that future control of subsidence and enhanced adaptation lessen flood impacts effectively. https://cdn.southampton.ac.ukhttps://www.southampton.ac.uk/engineering/news/seminars/2016/11/15-dr-thomas-wahl.pageTue, 15 Nov 2016 00:00:00 +0000 [16:00, 15 November 2016] Impacts of sea-level rise on human settlements and infrastructure primarily occur via extreme sea levels (ESL), which are modulated by mean sea-level rise (MSLR), rather than as a direct consequence of changes in mean sea-level alone. Hence, robust information on both MSLR and ESL is necessary for assessing impacts of and adaptation to MSLR. While substantial research efforts are directed towards quantifying projections and uncertainties of future global MSLR, corresponding uncertainties in ESL have not been assessed and projections are limited. This is exemplified by a very short and rather incomplete chapter on the topic in the 5th Assessment Report by the Intergovernmental Panel on Climate Change (IPCC), compared to an extensive mean sea-level chapter. In my presentation I will discuss, at global scale, the main uncertainties inherent to present-day ESL estimates, which have by default been ignored in broad-scale sea-level rise impact assessments to date. These uncertainties stem from hydrodynamic or empirical models used to simulate storm surges and from statistical methods used to parameterize extreme events. Combined, these uncertainties exceed those from global MSLR projections and, assuming that we meet the Paris agreement, the projected MSLR itself by the end of the century. It will be shown that it is crucial for risk and adaptation analysis to: (1) carefully assess present-day ESL with appropriate extreme value analysis methods, (2) make use of the improved computational capabilities and global reanalysis, and apply advanced dynamical models to simulate coastal sea levels; (3) extend model hindcasts and continue data archeology to obtain long enough time series for robust conclusions; and (4) exploit the rich and constantly growing (in time and space) observational data base to remove model bias wherever possible. The important recent and ongoing improvements in narrowing the uncertainties and providing more robust future MSLR projections are otherwise in danger of being of no benefit due to the uncertainties in ESL. https://cdn.southampton.ac.ukhttps://www.southampton.ac.uk/engineering/news/seminars/2016/11/8-dr-kwasi-appeaning-addo.pageTue, 08 Nov 2016 00:00:00 +0000 [18:00, 8 November 2016] Shoreline change has increased coastal erosion along the West African coast, which has destroyed the coastal environment and threatens coastal investments. Coastal erosion is a critical issue and has become the centre of debate in the sub-region in recent times. Coastal areas in West Africa are home to about 31% of the region’s population and growing at a rate of about 4 percent annually. The coast also accounts for 56% of the region’s GDP. Managing coastal erosion is consuming between 5 to 10 percent of the GDP of affected countries, which is a significant sum for the economies of developing countries. Although erosion is largely a natural process, human activities have exacerbated its impact within the coastal zone. Such activities directly impact the coast and indirectly influence the coastal processes by reducing the capacity of the coastal ecosystem to cope with natural phenomena. Coastal erosion in Ghana has destroyed coastal infrastructure ranging from urban areas to small fishing villages, threatens important cultural and historical resources, hindered coastal tourism development, and affected the socioeconomic life of the local population. Twenty five erosion hot spots have been identified along the Ghana coast with varying erosion intensity and drivers. Mitigation efforts by the government to manage the erosion situation have transferred the problem from one location to another. The situation is further worsened by the lack of effective policies and the adhoc approach adopted in coastal erosion management. This presentation critically assesses the causes of coastal erosion in the sub-region, focusing on Ghana’s experience and their impact on the socioeconomic life of coastal communities under climate change scenarios. The presentation ends with recommendations for sustainable management of the coastal zone.

Widely known examples include the Delfland Sandmotor and other projects sponsored by the Ecoshape consortium in The Netherlands. In the UK, the ‘sandmotor’ concept, marketed as ‘sandscaping’, has also been promoted over the past 5 years by the Crown Estate and their consultants, and proposals for a mega-nourishment project on the coast on northeast Norfolk are currently under discussion. Such large-scale schemes can have a significant and immediate impact on their immediate areas, but they are invariably expensive and the long-term success / sustainability is unproven, particularly if the mega-nourishment operations are undertaken as a ‘one-off’ exercise. Beach and dune nourishment projects ranging in scale from small to large have in fact been undertaken in many parts of the world for more than 50 years, and there is also a long history of creating, maintaining and managing beaches and coastal dunes extending back centuries. This presentation will examine the lessons which can be learned from these earlier interventions, and also from natural geomorphological analogues, with a view to assessing the likely long-term success and value for money of mega-nourishment schemes compared with the wider employment of smaller-scale beach and dune management measures. The performance of the Delfland sandmotor will be reviewed, and suggestions presented for an alternative, longer term and sustainable approach to coastal sand budget management, with examples drawn from Liverpool Bay , the East Riding of Yorkshire, and the Lincolnshire Coast.
