“…Although nourishment on this beach have met the project goal, beach nourishments can often cause large-scale nearshore disturbances that affect the balance of alongshore and cross-shore sediment transport (Dean, 1983). In general, the sediment transport on the beach without human intervention is mainly controlled by the hydrodynamic processes (Wiggins et al, 2019) and beach characteristics (Oliveira et al, 2017). Sediment transport on the beach can be more complex with human activities (Duvat et al, 2019;Luo et al, 2016).…”

Beach nourishment is a proved effective protection approach which has been widely used in recent years. An Argus video monitoring system has been set up to monitor morphological changes and effects of continuous nourishments at Dongsha beach, an embayed beach in Zhoushan Archipelago, eastern China. Video-derived shorelines along with their morphological parameters, such as dry beach width, dry beach area, beach orientation and unit width volume were analyzed during the monitoring period from June 2016 to July 2017. Analysis of video monitoring data shows that shorelines retreated during autumn and winter when storms were intensive, while advanced in spring and summer, with a lot of bulges occurred after nourishment projects. Abrupt variations in the beach orientation were always followed by gradual recoveries to the average beach orientation, while continuous counter-clockwise rotation occurred after March, 2017 when storm events were sparse. Comparing the different beach responses to individual storm events, we found that small-scale and short-interval sand nourishment implemented timely after storms can compensate for sediment loss more effectively on this beach. This study can provide a reference for local beach management.

“…Tracer studies have been carried out in various coastal environments. For subaerial coastal environments, most tracer experiments have been conducted in the intertidal area (e.g., Kato et al., 2014; Oliveira et al 20172009; Silva et al., 2007; Vila‐Concejo et al., 2004; Williams et al., 2003; Wright et al 2015…”

Coastal aeolian sediment transport is influenced by supply-limiting factors caused by sediment sorting by grain size. Sorting processes can lead to coarsening of the bed surface and influence the formation of aeolian ripples. However, the influence sorting processes and bedforms might have on the magnitude of the transport is not fully understood. This study explores sorting processes and their influence on the magnitude and mode of aeolian transport by using sediment tracers. Sand was painted in different colors according to particle size and placed on a supratidal beach in Noordwijk, the Netherlands. Several experiments were conducted with varying wind

“…According to various authors, the intrinsic factors that control the stability of beaches are the profile of the beach and the characteristics (size, density and porosity) of the sediments [1,29,35]. Therefore, sediments are an important part of understanding coastal processes [12].…”

The main objective to this work is to establish a relationship between shoreline evolution and sediment wear. The shoreline evolution trend is similar to of the results obtained by the accelerated particle wear test (APW). However, the relationship between the number of APW test cycles and the years of shoreline evolution is not clear. In Guardamar beach the ratio (years/cycles) is 9.7, in Marineta Casiana beach (it is 5.6, and in Arenal beach it is 3. Differences may be due to the different mineralogical composition and morphology of the sand particles.
