报告人简介： Stephen Darby is Professor of Physical Geography in Geography and Environment and Head of Academic Unit. He has worked at Southampton since 1997. He served as the Vice Chair (Research) of the British Society for Geomorphology (2012-2015) and is currently the Junior Deputy Chair of that society. His primary research interests centre on understanding the environmental processes that modulate the transfer of sediments from their terrestrial sources to their ultimate sinks, in the world’s great deltas and oceans. In recent years this work has comprised two main strands, one focusing on sediment flows through the world’s largest rivers and the second addressing geomorphological processes within the estuarine and coastal environment.
报告内容： Faced with global flood hazard and risk challenge, reliable tools are required to predict how flood hazard and exposure will change in the future. To address these issues my team and I have been engaged in a project “EVOFLOOD” in which we are developing an entirely new generation of Global Flood Models by: (i) using Big Data sets and novel methods to enhance substantially their representation of channel and floodplain morphology and roughness, thereby making GFMs more morphologically aware; (ii) including new approaches to representing the evolution of channel morphology and channel-floodplain connectivity; and (iii) combining these developments with tools for projecting changes in catchment flow and sediment supply regimes over the 21st century. In this presentation I would like to update you on the project and some its emerging tools, and point the way for the next phase of the work. |
