To guarantee the rapid and consistent growth in maritime trade, managers must employ suitable techniques to handle operational challenges and meet market needs. One of the critical decisions in operational planning is the allocation of berths. A well-designed berth allocation plan can greatly boost the productivity and competitiveness of seaports. Despite the extensive research on berth allocation, there remains a notable gap in studies focusing on low-carbon berth allocation. As energy shortages and global warming intensify, low-carbon has increasingly become key terms across various sectors. Under the circumstances, this work addresses a multi-objective stochastic berth allocation problem for minimizing the average carbon emission and total service time. Firstly, a stochastic programming method is employed to formulate the uncertain arrival time and operation time of vessels, then a multi-objective chance-constrained programming model is constructed to formulate the studied problem. Secondly, an enhanced multi-objective artificial bee colony algorithm incorporating stochastic simulation (EMOABC) is specially designed. Finally, a large number of comparison experiments between EMOABC and nondominated sorting genetic algorithm II (NSGA-II) are performed. Through observing and analyzing the experimental results, two conclusions are acquired as follows: (i) EMOABC obtains the smaller IGD values and larger HV values than NSGA-II on all the test instances, indicating that it has better performance than NSGA-II for solving the considered problem; and (ii) EMOABC uses less running time in dealing with test problems of different scales compared to NSGA-II, suggesting that it has lower computational complexity than NSGA-II.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"261 ","pages":"Article 107529"},"PeriodicalIF":4.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143165301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Managed coastal dune systems are becoming the new ‘normal’ along developed coastlines where natural dune growth is often inhibited. Understanding and optimizing managed dune systems is critical for maintaining dune health and resilience. Previous research evaluating dune management strategies and morphology broadly evaluated morphologic impact at varying spatiotemporal scales, but more work is necessary to translate these results to future managed dune systems. This paper investigates the role of the seaward stoss slope for dune evolution and response for two managed systems in South Carolina, U.S.: a nourished dune with a stoss slope of 12° (Site A) and a managed upper backshore with a stoss slope of ∼2° (Site B). Field-based topography and vegetation coverage data are presented for one year, including Hurricane Ian's near-direct impact. Results are subdivided into temporal periods (TPs) to present managed pre-storm, storm-response, unmanaged recovery, managed recovery, and full-study duration comparisons between both sites. Findings support that the variance in stoss slope between sites resulted in differential response throughout the entire study period, attributing to initial dune development rates and recovery potential. Statistically significant (p < 0.01) hot spots of erosion and accretion throughout each TP present site-specific patterns, coupled with contrasting post-storm volumetric changes: −10.5 m<sup>3</sup>/day for Site A and +0.73 m<sup>3</sup>/day for Site B. Vegetation growth from initial planting suggest correlations exist (p < 0.05) between cross-shore placement (e.g., slope) and vegetation growth and retention. Results demonstrate post-storm recovery is best supported in managed dune systems when roughness elements are reinstalled, warranting further investigation on recovery potential for managed dune design. Overall findings from this study suggest trade-offs exist in the benefits derived (e.g., rate, protective capacity) from managed coastal dune system construction metrics that should be carefully considered for future dune management, especially in regions where storms are frequently experienced.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"261 ","pages":"Article 107539"},"PeriodicalIF":4.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143165911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional ‘grey’ solutions, such as seawalls and groynes, while effective at a local scale and over the short-term, are costly, disrupt natural ecosystems, and have adverse ripple effects for downdrift coastal areas. Vegetative forms of Nature-Based Coastal Solutions (NBCS), which include the use of mangroves, saltmarshes, and seagrasses, offer a sustainable alternative, with wider environmental benefits apart from just coastal flood risk reduction. In this review, we examine the effectiveness of vegetative NBCS in mitigating coastal flood risk and consider the limitations, challenges and uncertainties around their implementation. We find that mangroves, saltmarshes, and seagrasses significantly reduce wave energy, attenuate storm surges, and stabilise sediments, with evidence showing up to a 72% reduction in wave energy by saltmarshes and a 66% reduction in wave height by mangroves. Also, we find that these ecosystems have the potential to contribute to long-term coastal resilience through carbon sequestration, biodiversity enhancement, and shoreline stabilisation. However, the effectiveness of these solutions can vary based on vegetation density, species type, and environmental conditions, pointing towards the need for targeted management efforts. Additionally, there are several ecological, environmental, socioeconomic, policy and geomorphology challenges associated with implementing vegetative NBCS. We discuss these as well as identify critical knowledge gaps on NBCS understandings for coastal flood risk management and outline new research pathways to address these gaps. Our review, therefore, has important implications for refining coastal flood risk management (both understandings and approach), communication strategies, and policies towards enabling more robust decision-making for sustainable coastal flood risk management.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"261 ","pages":"Article 107520"},"PeriodicalIF":4.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143164988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, dunes exhibit dynamic behaviours over a wide range of spatial and temporal scales, posing challenges for predicting their evolution. Here we demonstrate a high degree of variability in contemporary dune behaviour along a single coastal region, across 31 sites in Cornwall, southwest England. Rates of change varied widely, with sediment loss ranging from −12.4 m³/m/yr to a gain of +5.1 m³/m/yr, and dune retreat/advancement ranging from −3.7 m/yr to +1.6 m/yr. The results highlight four distinct modes of dune evolution: (1) volume gain with advancement, (2) volume loss with retreat, (3) volume gain with retreat, and (4) volume loss with advancement. These findings validate scepticism regarding the applicability of the Bruun rule over long timescales and underscore the importance of incorporating site-specific factors, such as sediment supply, aeolian transport, underlying rock surface and estuarine channel dynamics, into future model development. Nonetheless, this study demonstrates that combining contemporary dune behaviour analysis with the Bruun Rule offers a practical approach for initial predictions of future dune evolution. When combined with observed data, the Bruun Rule can effectively identify coastal change ‘hot-spots’ and guide coastal management decisions. Until more sophisticated models are developed, we recommend a staged approach for coastal managers: starting with regional-scale projections using observed trends and the Bruun Rule, followed by targeted application of reduced complexity and process-based models in areas of high concern.
