Ian provided specialist geomorphological input into the detailed design of river restoration solutions to address the impact of in-channel structures on the River Ouse in Sussex. This included the design of a new river channel at Sheffield Park and the design of in-channel features, gravel seeding and bank stabilisation measures at Buxted Park. He also provided input into the selection and design of options for a further four sites in the catchment. This work formed part of one of the Environment Agencys initial pilot catchments as part of the roll-out of the Catchment Based Approach to WFD implementation.
Ian was the lead river restoration designer for the production of detailed designs for the restoration of a 2.5km reach of the River Adur at Knepp Castle Estate, Horsham, West Sussex. His role included the design of a new river channel that is well-connected to the surrounding floodplain, the development of options to remove or modify three obsolete structures to increase flow and sediment transport and improve fish passage, and the design of backwater and riparian habitats.
