Examining coastal morphodynamics from the nearshore through to inland dune systems is fundamental in understanding their short- to long-term behaviour. Coastal processes operate across large spatial and temporal scales and therefore comprehending their resulting landforms is complex.

At the coast, dunes provide the physical barrier to flooding during high energy storms, while beaches and nearshore areas help dissipate storm impact through a series of dynamic interactions involving sediment transfers and at times rapid morphological changes. Investigation of complex interactions between these three interconnected systems has become essential for understanding coastal behaviour.

This session, sponsored by the IGU-UGI Commission on Coastal Systems, welcomes contributions from coastal scientists interested in the measurement and modelling of the nearshore 25-0 m zone (waves, currents and sediment transport) and terrestrial coastal processes (on beaches and dunes) and responses within the three sub-units at various scales. The session will highlight the latest research developments in this part of the planet's geomorphic system and facilitate knowledge exchange between the submerged and sub-aerial coastal zones.

Our two Solicited speakers this year are Adam Switzer (Nanyang Technological University, Singapore) on 'Investigating records of recent storms on a volcaniclastic barrier system in Bicol, Philippines' and Rob Young (Western Carolina University, USA) on 'Beach Nourishment as Storm Protection: Its Impact on Sediment Budgets and Ecosystems'.
