Abstract
This paper describes two large field campaigns designed to obtain the most
comprehensive dataset to date of morphodynamic change in the swash zone and the
associated hydrodynamic processes. Experiments were undertaken at a sand and gravel
beach to provide complimentary data from contrasting beach types. An initial analysis of
the data revealed that relatively large bed-level changes (1 – 2 cm) were observed to occur
in response to individual swash events. Indeed, itwas found that the net morphological
changes over a 2-hour section of data were not caused by the gradual accumulation of
small bed-level changes, but in fact the morphological response was dominated by a small
number of large events which had the same order of magnitude as the overall bed-level
change during the entire time-series
