Subsidence of coastal lowlands and delta’s

Session ID#: 25108

Session Description:
Many of the world’s coastal lowlands are subsiding. For these already low-lying areas, any further loss in elevation will make them even more flood-prone. For coastal areas, land subsidence is not a stand-alone hazard: eustatic sea level rise, predicted increases of storm and rainfall event frequency and intensity, but also soaring populations and ongoing urbanisation all contribute to increased vulnerability of these areas and their inhabitants.

Over the last decade, realising that subsidence is sometimes outpacing absolute sea level rise, there has been an increasing interest in coastal subsidence research, supported by advances in the scientific understanding of subsidence processes and measurement techniques. For this session, appropriately organised in the subsiding Mississippi delta, we invite all contributions on coastal subsidence, including contributions from disciplines such as geodesy, soil mechanics, geohydrology, physical geography, engineering, and studies on peatlands. We explicitly invite studies that look at the socio-economic implications of coastal subsidence.
