New paper: Hydrologic versus geomorphic drivers of flood hazard

Our paper titled Hydrologic versus geomorphic drivers of flood hazard – which separates and quantifies the effects of trends in streamflow and trends in channel capacity on flood hazards – has just been published in Geophysical Research Letters. The detailed methods can be found in the supplementary materials.  An article was recently released on this work on the Flooding and Coastal Erosion Risk management network (FCERM.net).

Inaugural meeting of the Environment Agency’s open-access Data Advisory Group (EADAG)

On Tuesday 18th November, I attended the inaugural meeting of the EA’s Data Advisory Group. Surprisingly, many members of the group (including myself) were interested in hydrometric data for flood hazard assessment. The EA explained that they are committed to publishing as much of their data as possible, and making it open access to the public under the Open Government Licence (OGL). So far, 101 of their 17,000 datasets have been published. The difficulty is prioritising what data should be released first, given the difficulties associated with preparing the data for release. Comments and suggestions for the EADAG can be shared via the EA’s website, twitter feed (@dataenvagency), or email (opendata@environment-agency.gov.uk).

Early Career Researcher Grant

Delighted to have received a British Society for Geomorphology Early Career Grant for a project entitled ‘To what extent have changes in river channel capacity contributed to flood hazard trends in England and Wales?’

Outline: Freshwater flood damages have increased dramatically over recent decades, and are of concern to millions of people living in flood-prone areas across the world. Most studies assume that trends in flood hazard are caused exclusively by changes in hydrology and climate. However, widespread anthropogenic influences to river systems have caused changes in the capacity of river channels, which can also modify flood hazard.

The aim of this project is to investigate how geomorphic changes in channel capacity have contributed to changing flood hazards, in comparison with hydro-climatic trends in the frequency of flood flows, in England and Wales. The grant will allow me to supplement data provided by the Environment Agency and Natural Resources Wales with field trips to obtain quantitative and qualitative channel characteristics to understand the causes of geomorphic change at each site; and to disseminate my work at the AGU Fall meeting in San Francisco, later this year.

Research Seminar on the Compared Effects of Hydrology and Geomorphology on Flood Hazard

I will be presenting some of my recent work at the upcoming research seminar in London: Compared Effects of Hydrologic and Geomorphic Trends on Flood Hazard Across the USA
