Description :
In this paper pebbles marked by passive integrated transponders from 2 artificial coarse-grained beaches at Marina di Pisa (Tuscany, Italy) were analyzed in order to measure the in situ abrasion rate. The beaches (Cella 7 and Barbarossa) were set up in 2006 as a form of coastal protection. The RFID technology (Radio Frequency Identification) was used to track the pebbles due to its reliability and limited costs. The tracers were released on the beaches in March 2009. The pebbles that were recovered in May 2009 showed a significant increase in roundness, in particular the tracers that were released on Barbarossa. The average pebble weight loss measured at Cella 7 was slightly lower, which means lower mobilization rate at this site rather than at Barbarossa. The resulting values are significant considering the short time frame of the research (2 months) and the limited energy of the storms occurred during the experiment. - (NF)
