Abstract
Photo-Electronic Erosion Pins (PEEPs) can be used to measure short-term fluctuations in swash zone (foreshore) profiles. Because the sensors depend upon ambient light for the detection of bed elevation change, their signal indicates false changes during swash inundation. A method is presented to mitigate this source of noise and to allow a reconstruction of bed changes at swash frequencies. The protocol is illustrated with a sample data set.
