Landscape sensitivity to past and future climate: solving the intermittency puzzle.

I am a PhD researcher funded by the NERC Science and Solutions for a Changing Planet (SSCP) DTP between The Grantham Institute and Imperial College London. 

My research focuses on past and present rivers, and how their response to climate change can inform projections of how sensitive fluvial systems are to future changes in climate. In particular, intermittent rivers which only require one flood every year or so could see drastic increases in sediment transport flux when storminess and precipitation patterns change due to global warming. This could have significant implications for geomorphology, landscape dynamics, and people living in intermittency river catchments. 

I am using precipitation pattern modelling and modern and palaeo-hydrology to help solve this problem.
