BESL engineer wins CIWEM East of England Graduate Paper Competition

Matthew Philpot, BESL Engineer, won the CIWEM (Chartered Institute of Water and Environmental Management) East of England Graduate Paper Competition in April 2005. In addition to submitting a paper Matthew was required to give a presentation on his research.

Matthew's study, entitled 'A Novel Wave damping device for the protection of riverbanks from boatwash waves' was based on an experimental study conducted as part of his BEng (Hons) degree course and looked to investigate methods of artificially replicating the wave damping effects of submerged vegetation.

The study looks in particular at the kelp plant Laminaria Hyperborea as a means of protecting riverbanks against boat wash waves.The study concentrated on boat generated waves typical of those found on the Norfolk Broads through using data previously recorded as part of a study conducted for the Broads Authority by May et al (1986).

Two physical models were made to replicate the motion of the Kelp plant which were then tested in the wave flume to monitor if they could reduce the transmission of wave energy. After modelling the results wave energy reduction was seen by both models.

The idea also has the potential to cause sediment to build up around the artificial seaweed, which is advantageous especially on eroding riverbanks as it induces sediment deposition without the need for importing material.

The idea is now being trialed in partnership with Seabed Scour Solutions Ltd on site as part of the compartment 35, Haddiscoe Island works and the results are eagerly anticipated.

Matthew will enter the National Finals in Autumn 2005 and all of us at BESl wish him the best of luck.
