EGU2019 - Sessions on Coastal Risk: NH8.1/GM5.13NH8.1/GM5.13I3.9 and NH8.2/GM11.12NH8.2/GM11.12 (Vienna, 07-12/04/2019)

Cari colleghi,
mi permetto di segnalarvi due sessioni sul rischio costiero che il mio gruppo di ricerca sta organizzando alla prossima assemblea di EGU a Vienna
Trovate maggiori dettagli sulle sessioni sotto. Ambedue sono co-organizzate dalla Commission on Coastal Systems della International Geographical Union
Session NH8.1/GM5.13NH8.1/ GM5.13 Ecosystem-based approaches to coastal Disaster Risk Reduction: new tools and case studies (co-sponsored by IGU-CCS) (co-organized)  
Convener: Paolo Ciavola  | Co-conveners: Clara Armaroli , Jenny Brown , Pushpa Dissanayake
Some of the major coastal disasters in the past decade have clearly demonstrated how nature has a primary role in reducing the impact of extreme coastal flooding events generated by storms, which produce a high cost to society as well as a threat to valuable ecosystems. After Typhoon Haiyan in the Philippines in 2014, the Government financed USD22 million for the restoration of mangroves along the affected coastlines as evidence grew showing that where coastalvegetation was present, this attenuated the magnitude of flooding. Similarly, following Hurricane Katrina the US government invested USD500 million for the restoration of coastal national parks and salt marshes, accepting the proofs that marshes helped to reduce the damage, in association with dike and levees. Thus, it is a prerequisite to propose that the reconstruction of ecosystems should be done before an event strikes, with a philosophy of prevention rather than a remedy, with a philosophy of recovery. In Europe too, many member states have started to promote the recreation of coastal wetlands, considering setback strategies as well as the reconstruction and vegetation of coastal dunes, which act as the first line of defence to flooding. As it is stated in the recently released EU-Science for Disaster Risk Management 2017 Report, a number of European Commission-funded demonstration projects are now supporting ecosystem-based Disaster Risk Reduction, to prove the added value of such an approach compared with traditional engineering solutions. 
This new approach demands: the development of new tools to model and design these reconstructed environments; merging physical concepts like bed erosion and sediment transport with the parameterization of biologically-induced phenomena, such as the role of emerged and submerged vegetation in attenuating wave and current energy; as well as the role of plants in stabilising/destabilising the morphology of coastal dune systems. 
The session welcomes contributions covering modelling and monitoring aspects, including innovative approaches in coastal morphological models that account for the presence of the ecosystems, quantifying feed-back interactions between the physical and biological components. We welcome case-studies reporting recovery of the ecosystems and of the physical environment following major extremes such as tropical and extra-tropical storms. We also welcome contributions on case studies documenting new techniques for revegetation of submerged as well as subaerial environments.
Session NH8.2/GM11.12NH8.2/ GM11.12 Documenting the impact of storms along sandy coasts: interactions between physical, ecological and societal dynamics (co-sponsored by IGU-CCS) (co-organized)  
Convener: Clara Armaroli  | Co-conveners: Derek Jackson , Denise Reed , C. Viavattene
Sandy coastal systems, shaped by interactions between waves and ecological processes, are important for society. When large storms affect a coastal area, modification of the beach can be dramatic, leading to large erosion and inundation of landward, often populated, territories. To fully evaluate the impact of storms, different disciplines should come together to provide a comprehensive assessment of the consequences on the coast from energetic events. The persistent erosion of natural shores can have a dramatic impact on ecosystems; where human occupation is present, storms can affect the socio-economy of coastal communities, threaten human lives, damage or destroy human assets. To prevent, mitigate, prepare and recover from the impact of energetic events, several types of actions are required at different political and management levels. The increasing interest in ecosystem-based approaches, and expanding use of coastal systems, outlines the importance of examining the interaction between the ecological, physical and societal components.
This session explores the coastal areas affected by extreme events from a multidisciplinary point of view. Abstracts should present research activities that involve direct measurements of the behaviour of coastal systems (both the physical and the ecological components), over various temporal (e.g. the impact of a single event or the long term evolution) and space scales. We especially welcome contributions from scientists that present multidisciplinary works from ecology to biology, sedimentology, geomorphology and socio-economy.
