A method to nourished beach stability assessment: The case of China

Beach nourishment has complex implications for the future of sandy shores

“…The 'success' of beach nourishment projects, viewed in terms of how the sand is redistributed by waves and wind, can be difficult to assess accurately as there is no single set of widely agreed criteria and the success depends on the objective 28 . Consequently, using retention time of sand in the original placement region as the prime criterion to assess 'success', can lead to the conclusion that the nourishment has failed, especially if the objective was to locally increase beach width for recreation 49,65 or provide a temporary buffer to storm impacts on landward infrastructure 66 .…”

“…The traditional monodisciplinary assessment of beach nourishment performance, used across the globe e.g. 28,63,64,212,213 , typically focuses on geometrical aspects alone (like beach width or beach volume). Visitor appreciation surveys and economic evaluations (in Cost-Benefit analysis 214 , Travel Cost Method or Contingent Valuation Method 215 , for example) are also used widely despite often oversimplification of nourishment impacts, especially ecological impacts.…”

“…More recently, owing to the recognition of the interconnectedness of regional littoral cells and their sediment budgets 24 , repetitive nourishments along the coast are coordinated in regional sediment management plans 25 using either newly acquired sand or reusing dredged sediments (such from maintenance of nearby harbors). Some novel individual placements have been scaled to substantially modify the regional sediment budget over many years, such as in mega-nourishments (> 500 m 3 /m alongshore [26][27][28] ).…”

Evaluation and Application of New-Semarang Coastal Resources Management

“…The choices of resources become an essential matter that influences the direction of utilization. It means that utilizing the type of resources might require shifting to be raised into a new attraction (Brand & Spencer, 2019;Liu et al, 2019).…”

“…The existence of the potential of these natural attractions cannot develop optimally. This condition has become a valuable component, including ecosystems, communities, and socioeconomic risks under pressure from marine dynamics (Liu et al, 2019).…”
