Ian Guymer has a track record of quality academic papers published in highly rated journals and at selected international conferences and has been awarded over twenty-five major research grants with total research funding in excess of £10M. His research is focussed on transport and mixing processes related to soluble pollutants and contaminated fine suspended sediments in river, coastal and urban drainage systems.
Quantifying fundamental mixing processes
• Effects of cross-sectional shape and plan-form curvature on solute mixing.
• Contribution of aquatic vegetation to longitudinal mixing in channels.
• Residence time distributions for urban drainage structures.
• Influence of laminar boundary layer on low Reynolds number flow in pipes.
• Measurement of hyporheic exchange across bed sediment-river flow interface and the variations within the sediment bed.
Developing robust numerical modelling techniques
• Developed national database for travel time and dispersion to allow predictions for ungauged natural rivers.
• Quantified enhanced solute mixing due to waves in both near-shore and surf zone.
• Integrated system for including both cross-sectional shape variations and curvature for predicting transverse and longitudinal mixing processes.
• Simulation of hyporheic exchange processes.
Application to natural water quality processes and ecology
• Investigation of the effect of highway run-off on receiving water ecology.
• Operation and efficiency of constructed wetland systems and ponds.
• Predicting effect of sediment resuspension on river water quality during overflow events.
• Fate of surfactants within urban drainage and river systems.
