Research interest: Within the Global Change research group, I am part of the Land Surface Dynamics research group (FOLLOW US ON TWITTER: http://twitter.com/edinlandsurf). I combine the analysis of real landscapes (collection of field data, topographic analysis) with numerical modelling and experimental studies to constrain the relationships between tectonics, erosion and the development of topography. My current research focuses on understanding the coupling between hillslopes and rivers, characterizing and quantifying fluvial erosion and transport processes in mountain rivers, and defining the role that sediments play in modulating fluvial erosion rates. My work can help extracting tectonic information from topography, with implication for assessing seismic and landslide hazard. Understanding the release and transfer of sediment can also help retrieving past tectonic and climatic signals in the geological archive (stratigraphy), as well as mitigating risks in sedimentary basins. The risks I am particularly interested in at the moment include flooding risk from in-channel sediment aggradation (e.g., response of Himalayan rivers to the recent Nepal 2015 earthquakes), and siltation and heavy metal pollution (e.g., new project on the environmental impact of nickel mining in the Philippines).

PhD students:

LAURA QUICK is investigating sediment dynamics at the front of the Himalayas, from Neogene to modern times.
BORIS GAILLETON is looking at post-orogenic evolution of the Carpathian mountain range.
JUSTINE DOMINGO is investigating sediment and pollutant dispersion in mining-affected areas in the Philippines.
EMMA GRAF has joined our Himalaya research team to constrain sediment transfer from source to sink.
CALLUM STRONG is investigating the effect of rock types on landscape morphology and the propagation of environmental signals. He is currently focusing on the Nile River.
MASOOD REHMAN is assessing the feasibility of a community-based early warning system on the basis of vulnerability analysis in Balochistan, Pakistan.
ANTHONY HOSKINS is joining us this year to work on a project entitled “Drainage reorganization in South Baja California, Mexico: using landscapes to reconstruct the history of tectonically complex areas”.
Past students:
Dr CHRYSTIANN LAVARINI looked at bias in the detrital record due to pebble abrasion. He is now working on geomorphological issues related to mining for Golder, an environmental consultancy in Brazil.
Dr REBEKAH HARRIES unravelled climate and tectonic changes in the sediment record using the Jáchal region, South Central Andes as a natural laboratory. She is currently doing a postdoc at the CIGIDEN (Centro de Investigación para la Gestión Integrada del Riesgo de Desastres) in Chile.
Dr LIZZIE DINGLE constrained river dynamics in the Himalayan foreland basin. She is currently doing a postdoc at Simon Fraser University in Canada.
Dr FIONA CLUBB modelled the competition between climatic and geologic control on the development of landscapes. She is now Assistant Professor at Durham University.
Dr EDWIN BAYNES has quantified bedrock erosion during extreme flood events in Iceland. He is starting a lectureship at Loughborough University this year.
See Ed’s Icelandic videos: Iceland PhD fieldwork June 2012 —– Iceland PhD fieldwork part 2, August 2012 —– A field work saga, Iceland 2013 —– Iceland: a research story.
Listen to Ed talking about his project on Radio New Zealand National (the interview covers many aspects of his project, it’s very nice – don’t get distracted by the opening sentence!): Podcast.
Dr MARTIN HURST used hillslopes as recording devices to investigate how landscapes adjust to tectonic changes. He is now Lecturer at the University of Glasgow.

TOPOGRAPHIC ANALYSIS

– LSDTopoTools Package

The Land Surface Dynamics group has released a package to do topographic analyses, including the “chi-analysis” (see Perron and Royden, 2013) which has the advantage of not being sensitive to the noise inherent to topographic data (i.e., slope-area data tend to be very noisy because of steps in river profiles). The paper presenting the tool and its application is available: click here. Simon Mudd and his team of hackers have designed a book in addition to the package. Both can be found on Github: the book and the package. Feel free to try it and give some feedback!

Video of the Inchnadamph field trip (NW Scotland):

This is a lovely video made by Simon Jung about the two-week field trip that third year students in Earth Science attend. A nice taster of Scotland and its amazing geology and landscapes (to me, this is one of the most beautiful places in the world): http://www.youtube.com/watch?v=Xe12VVXh93A&feature=youtu.be.

GRAVEL BED RIVERS CONFERENCE 8, September 2015:

The Gravel Bed Rivers conference 8 just took place in Kyoto and Takayama, Japan, on the theme “Gravel bed rivers and disasters”. The conference takes place every five years and leads to the production of a book presenting the work shown in the talks. You can find the list of talks (and therefore, incidentally, book chapters) there: GBR8 Programme. The talks have been recorded and can be seen there: GBR8 talks (my talk is in session 7, starting at ~30 minutes). The book is now available here. In the meantime, if you are interested in my talk on “Linkage between sediment transport and supply in mountain rivers”, here is the ppt: Part 1 and Part 2.
