Simon's primary research focus is on the processes associated with erosion, transportation and deposition of sediment in river and urban drainage systems, with a strong emphasis on fundamental flow and grain processes. Linked to this theme is his work in turbulence and free surface wave dynamics associated with flows over rough, water worked sediment deposits. His secondary interests are in applying and developing improved measurement and management methodologies to allow urban water infrastructure systems to cope better with pressures caused by climate change, changing patterns of use and physical deterioration. Current work also includes the study of energy use and recovery in urban water systems.
