“…Furthermore, Allan (2006) and Dickson et al (2011) have reported that the distance an individual sediment particle travel can influence abrasion percentage losses. Dornbusch et al (2002Dornbusch et al ( , 2003 have investigated the influence of wave conditions on abrasion, finding that abrasion rates are linked to mean wave height. Bertoni et al (2011Bertoni et al ( , 2012 explained the difference in abrasion rates of pebbles released on the lower swash zone (4.2%) and those pebbles on the upper swash zone (1.6%) as a function of differences in wave exposure.…”

“…However, this is not sufficient to explain the variations in abrasion rates as it is only based on the change in offshore wave heights similar to Dornbusch et al (2002Dornbusch et al ( , 2003. Due to the complicated process by which waves transfer from the sea to the beach, more detailed consideration is required, especially for the process of wave transfer from the breakpoint to the termination of the upwash on the beach.…”

“…Although this method enabled the recognition of the sample pebble, the tracer sediment could be used only once. Dornbusch et al (2002) and Dornbusch et al (2003) engraved 1 to 2 mm deep nicks in 431 exotic pebbles and marked each with a water resistant marker pen. They used 217 quartzite and 214 limestone pebbles to distinguish from the local flint.…”

“…The abrasion rate of beach sediments depends on pebble characteristics (especially hardness), hydrodynamics (especially wave energy), and exposure (especially the amount of time exposed to transport) (Dornbusch et al 2002;Cammelli et al forthcoming). The iron-rich sediments that remain on the active foreshore surface at Cavo are more rounded and better sorted than sediments at depth (Figures 3 and 4), revealing that some sorting and reshaping by waves has occurred in only three and one-half years.…”

The surface characteristics and dimensions of many beaches reflect past inputs of sediment due to human activity in tributary drainage basins. Subsequent control of erosion in drainage basins, changes in flow regimes of streams, and construction of shorefront structures have reduced sediment input and eliminated beach area in many coastal segments, leading to calls for artificial beach nourishment. This study evaluates the compatibility of sediments delivered as a result of human activity in terms of the appearance and utility of beaches by comparing sites on Elba Island, Italy. Beach morphology, mineralogy, grain size, and roundness of sediments were determined for five sites where sediments were introduced by artificial nourishment, by erosion of spoils from iron mines, and by stream flow through agricultural or mining lands. Size, sorting, angularity, and color of sediments determine their acceptability by beach users. These characteristics were determined by evaluating the mineralogy and method of delivery of sediment (rivers, bluff erosion, and artificial replenishment) and subsequent modification by wave and human action. Wave energy and time are critical to the reworking of sediments to achieve more natural characteristics, but these constraints can be overcome by more careful selection of the mineral characteristics of fill sediments, prewashing fill sediments to remove silts and clays to reduce turbidity, grading nourished beaches to cycle sediments into the wave and swash zones to cause better rounding of sediments, or raking the beach to create the sandy backbeach that is favored by beach users.

“…On the other hand, during stages of reduced eruptive activity (as, for instance, in the interval 1938-55 or 1987-2001), a diffused reduction in beach volume has been documented, possibly induced by washing out and loss of sediment to deeper waters under storm conditions and/or by in situ abrasion (see also DORNBUSCH et al, 2002).…”

Rapid shoreline changes at Stromboli Island have been documented from maps and aerial photographs dating from 1938 to 2003. Shorelines digitized from aerial photographs, taken at decadal intervals on average, show that while cliffed tracts were relatively stable, beaches on the N and NE side of the island experienced alternating accretion and erosional stages linked, respectively, with the contemporary eruptions and with sediment redistribution and/or the washing out and loss of sediment to deeper waters. Sciara del Fuoco, on the central-western side of the island, is where most of the volcanic products have accumulated during the practically continuous activity of the last two thousands years; from there, sands and gravel drift alongshore and are added to beaches on the N and NE side of the island. A simple model of clockwise longshore drift along the W, N, and NE coasts of the island is presented, taking into account the influences of manmade structures on shoreline changes
