Abstract
A swash flow transducer was constructed to record wave energies and swash
velocities measured via a system of marker poles. Long (4m) metal poles were
installed on a gravel beach located at Nash Point, South Wales, UK, a rugged,
high energy, coastal environment. These were secured to three 30kg concrete
anchoring legs per pole buried in the beach. A Rustrak Event recorder with
manual trip pen device recorded the time taken by a series of swash edges to pass
each marker pole. Twenty such consecutive swashes were monitored over various
tidal stages. The event recorder also obtained wave period, swash period and run
up. Profiles and surface sediments were also recorded both before and after each
experiment. Non-parametric testing of the sediment samples pre and post
experimen
