In addition to direct shoreward translation of the coastline due to rising sea levels, many coastal areas are likely to experience large changes as a result of climate induced variability in environmental forcing. A number of recent studies, particularly in the Pacific, have documented considerable coastal variability resulting from changes in wave height and/or direction associated with both inter-annual (e.g. El Nino/La Nina) and longer term (e.g. Pacific Decadal Oscillation) climate fluctuations. These observations provide a window into the future as many climate models currently predict latitudinal shifts in storm intensity and tracks (and thus wave direction), increases in the frequency and intensity of periodic climate events (e.g. El Nino), as well as changes in sediment delivery to the coast. Improving our understanding of coastal processes overall, as well as understanding coastal response to past climate events and changes is instrumental in determining how our coastline will respond as climate changes. The session will solicit abstracts covering improved understanding of coastal morphodynamics, observed coastal response to climate changes/events, as well as efforts to predict the likely evolution of the coastline to changes in any aspect of the climate, including waves, sea levels, sediment delivery, and coastal-estuary coupling.
