Dr Ian Pattison BSc, PhD
Lecturer in Water Engineering
Ian graduated from Durham University in 2006 with a BSc in Physical Geography. Between 2006 and 2010 he completed his PhD, titled "Rural Land Management Impacts on Catchment Scale Flood Risk", also at Durham University. He then moved to the University of Southampton (2010-2012), as a Research Fellow, on a DEFRA funded project entitled "Extending the evidence base on the ecological impacts of fine sediment and developing a framework for targeting mitigation of agricultural sediment losses". In May 2012, he took up his current post as Lecturer in Water Engineering in the School of Civil and Building Engineering at Loughborough University.
Broad interests and expertise
- Catchment Hydrology
- Flood Risk, Channel Hydraulics
- Sediment Transport
- Aquatic ecology
- Stakeholder engagement
- Member of the British Hydrological Society
- Member of the British Society for Geomorphology
My research interests are primarily related to catchment hydrology, channel hydraulics and how these interact with the continuum of sediment erosion-transportation-deposition.
Specifically the substantive research questions that I address are:
- the impact of climate change and land management practices upon both high and low river flows.
- the relationship between channel processes and landforms
- the tracing of sediment from hillslope to channel and within the channel
- the role stakeholders play in catchment management the impact of suspended sediment on aquatic species
Previous research projects
2006 Sprout Project, with Professor Stuart Lane (at Durham University, now at the University of Lausanne)
GIS (Geographical Information System) based sediment delivery model, SEDMAP, used to predict the probablistic risk of coarse sediment delivery to the river channel for the Ouse catchment in Yorkshire, UK.
2006-2010 PhD Rural Land Management Impacts on Catchment Scale Flood Risk (supervised by Professor Stuart Lane, Dr Richard Hardy and Dr Sim Reaney, Durham University)
- Statistical Downscaling of catchment scale high flows to determine the most important contributing sub-catchments using Principal Components Analysis and Stepwise Regression.
- Hydraulic modelling, using iSIS-Flow, to upscale sub-catchment scale impacts of land use to the catchment scale
- Hydrological modelling of land use impacts, including agricultural compaction and forestry land cover, on extreme river flows (high and low flows) using CRUM-3 (Connectivity of Runoff Model).
- Stakeholder engagement with organisations such as the Association of Rivers Trusts, the Eden Rivers Trust, the Environment Agency, United Utilities and the RSPB, to co-produce land management scenarios that were feasible to be implemented.
