Abstract

This session tackles the multiple disciplines converging on coastal restoration, focusing on vulnerable estuarine and deltaic systems that require upscaled restoration to restore ecosystem services for safeguarding coastal functions. Such restorations will demonstrate the benefits of ecosystem services when compared with conventional engineering, aligned with the EU Green Deal and building upon the recent REST-COAST EU project. The session will be organized along three axes: i) restoration supported by monitoring and maintenance, ii) restoration benefits and trade-offs assessed by data and modelling, iii) restoration for coastal adaptation and delivering climate mitigation. The session will convene experts and stakeholders to discuss the technical, financial, economic and governance dimensions required for an “adaptation–through–restoration” plan. Contributions on restoration efforts in degraded deltas and estuaries worldwide, including the REST-COAST pilot cases are welcome. The presentations can consider from short (extreme events) to long (decadal climatic trends) time scales and multi-risk cascading effects. In addition, contributions on the uncertainties in ecosystem service delivery or climate-compatible solutions are also invited. The session will address synergies and tradeoffs associated to systemic restoration, with a focus on deltaic and estuarine systems. The conveners are planning a special journal issue, fostering papers co-authored by researchers and stakeholders.

Title

What parameters drive best for future shorelines shelter?

Organizers

Abstract

This session opens the discussion by hosting short initial presentations summarizing the present scientific knowledge of the interaction between hydrodynamic pressures, morphological processes, sedimentological parameters and vegetation properties on stability as well as erodibility of estuarine and coastal shorelines. Presentations are addressed in this session having results which range from in situ experiments and monitoring results to modelling results to laboratory experiments. The short presentations and a joint discussion to answer the guiding questions are equally distributed in time. The guiding questions are: Can parameters and ecosystem functions be quantified that drive stress responses (initiate erosion) and resilience (accretion and recolonization of sediment) on vegetated shorelines? How can the knowledge be used to promote resilient nature-based solutions for human-altered shorelines exposed to climate change?
