Ian Guymer graduated from Loughborough University of Technology, in 1981 in Civil Engineering. This was followed by a PhD degree, awarded from the University of Birmingham in 1985, on aspects of solute mixing processes in well-mixed estuaries. His first academic appointment was as at Heriot-Watt University, Edinburgh, followed by an appointment to the lecturing staff within the Department of Civil and Structural Engineering at the University of Sheffield in 1990.
In January 2005, he was appointed Professor of Civil Engineering at the University of Warwick. A Chartered Engineer and a Member of the Chartered Institution of Water and Environmental Management, his research interests are centred around identifying and quantifying the transport and mixing processes related to solutes and fine suspended sediments within civil engineering hydraulics. This is achieved by undertaking laboratory and field studies into mixing processes and developing simplified modelling procedures for engineering applications. Recent close collaboration with biologists has led to improved understanding of the effects of contaminants on the receiving water ecology.
Research projects have been concerned with mixing processes in urban drainage and treatment systems, looking at specific components, such as manholes and combined sewer overflow structures, wetlands and ponds, river systems, quantifying dispersion effects due to topographic variations, estuarine studies and coastal mixing processes. These topics are particularly important for modelling water quality processes. He has been funded to undertake research studies on both UK national hydraulic facilities, the Flood Channel and the Coastal Research Facility, formerly situated at HR Ltd., Wallingford and major European research laboratory facilities at DHI and Delft. In recent years, fundamental research has been funded by EPSRC, NERC, and the EU, with applied research funded by Unilever, Water utilities, the Environment Agency and the Highways Agency.
