Firstly, using the Digital Shoreline Analysis System (DSAS) tool, high spatial resolution satellite imagery, coastal changes were assessed over various time scales covering the decade of 2013–2022. Secondly, considering the same timeframes, wave storm characteristics occurrence and characteristics of Iztuzu beach were assessed. Lastly, the coastal evolution and wave storm assessment results are linked based on correlation analysis to define the relation between the observed coastal changes and the wave storm frequency and characteristics changes. Thus, the present study's main advance lies in considering the impact of some key characteristics of wave storms, such as storm duration, direction and total energy, on shoreline evolution. The correlation analysis of shoreline changes and storm characteristics revealed the influence of wave storms on coastal dynamics. The study results highlight the significant sensitivity of certain beach zones to storm characteristics and point out the possibility of predicting future shoreline changes using projected wave storm patterns. Throughout the study period, Zones II, III, and IV experienced consistent erosion, likely attributable to the interaction between the southwest-oriented shoreline and the prevailing storm wave direction from the South. This alignment generates strong drift currents, contributing to the observed shoreline retreat. For instance, the correlation exceeded 0.8 at Zones III, IV, and V for wave storm duration, SPI and TSWE against the EPR, and 0.7 at the same zones for the same characteristics against the LRR. As a result, coastal erosions at Iztuzu Beach are more linked to the intensity and duration of southern wave storms. Thus, this study emphasizes the importance of combining wave storm data and shoreline analysis to develop effective coastal management and mitigation strategies.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"267 ","pages":"Article 107748"},"PeriodicalIF":4.8,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144105998","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}

Due to reduced sediment supply and strong coastal dynamics, deltaic coasts are struggling to maintain shoreline progradation, necessitating urgent needs for integrated and data-enriched vulnerability assessments to address erosion risks. However, previous studies have often been constrained by observational datasets and lacked a systematic analysis of erosion vulnerability in deltaic coasts during varying periods under combined human activities and climatic changes. The modern Yellow River Delta (YRD) serves as a typical river-dominated delta system, currently undergoing geomorphic transition and facing erosion risks due to changing environmental conditions. This study integrates methods of numerical modeling, Analytic Hierarchy Process (AHP), and Coastal Vulnerability Index (CVI) to develop a comprehensive framework for assessing coastal erosion vulnerability. We then apply this framework to evaluate the erosion vulnerability of different coastal segments of the YRD, using multi-year hydro-geomorphic and human-interfered indicators. The results reveal that the overall erosion vulnerability of the YRD has decreased during 1992–2015, characterized by pronounced spatial and temporal disparities. The abandoned northern YRD exhibits high erosion vulnerability, primarily due to the absence of fluvial sediment supply, strong coastal currents, and the additional impact of wave climate. In contrast, the artificially protected coasts and western Laizhou Bay show relatively lower vulnerability marked by coastal protection measures and weak hydrodynamic influences. The segment of Qingshuigou delta lobe shows high vulnerability in sediment-starved areas, attributable to both engineered diversions and natural channel migration. Future management strategies should integrate coastal protection measures with wetland restoration efforts, as well as optimize riverine water and sediment regulation within the river basin and deltaic channels to enhance riverine sediment delivery to severe erosion zones.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"267 ","pages":"Article 107760"},"PeriodicalIF":4.8,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084646","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}

Beaches are popular for their tranquil ambience and offer a variety of pursuits, such as swimming, walking, fishing, and constructing sandcastles. Coastal tourism and recreation play a significant role in national economies by attracting both domestic and international visitors. However, recreational beaches can also pose health risks due to microbial contamination from diverse human and fecal sources. The presence of pathogens in recreational beaches can lead to various health issues such as gastrointestinal, acute febrile respiratory tract, nasal cavity, ENT, eye irritation and skin-related infections. Swimming and bathing in polluted coastal waters cause over 120 million gastrointestinal illnesses and 50 million cases of severe respiratory disease annually. This not only restricts local residents and international tourists from utilizing the beaches but also results in economic losses and psychological impacts for affected individuals. Therefore, regular monitoring and assessment of recreational beach water quality is crucial in preventing contamination and the spread of infections. This review article examines the growing environmental and public health concerns surrounding microbial contamination in marine recreational areas. Despite the health risks, in developing and underdeveloped nations, the scarcity of comprehensive monitoring of recreational water quality poses significant health risks.

However, managers in Myanmar have inadequate data for regulating coastal fisheries. To help address these data deficiencies, we implemented a digital catch data collection system to quantify the diversity and volume of catches coming from the inshore fisheries of southern Myanmar. Our data from the Tanintharyi region showed a high diversity catch (49 fish families), with commercial transactions greatly dependent on a few key families (e.g., Scombridae, Carangidae) for local and regional trading. We also identified the importance of tonguesoles (Cynoglossidae), frequently caught as bycatch, as an essential contribution to the local food supply. Tonguesoles are unreported and unregulated but are of high socio-economic importance, providing a source of affordable, high-quality protein and income to coastal communities. Here we use Cynoglossidae as an example of a single fish family that can be used to make general management recommendations for a poorly understood but highly diverse inshore fishery in Myanmar.
