✦ Synopsis

This paper replies to TE Baldock's discussion [Coastal Eng. 56 (2009) 380-381] of 'Measurement of wave-bywave bed-levels in the swash zone' by Turner et al. [Coastal Eng. 55 (2008) 1237-1242]. We address and extend the comparison and discussion of ultrasonic bed-level sensors and buried pressure transducers to obtain estimates of the beach face elevation within the swash zone. We demonstrate the use of the former method to obtain many and continuous (every time the beach face is exposed) in-situ estimates of net sediment flux per swash.

A technique is described to observe and quantify wave-by-wave bed-level changes in the swash zone. The ultrasonic instrument system is non-contact with the beach face surface being measured and the sensors remain outside of the fluid flows causing sediment movement. Sensor resolution combined with t
