A tide-wave-sediment numerical model was built and validated for Hangzhou Bay (HZB), using reconstructed near-shore typhoon wind fields. The model incorporates wave-current coupling and water-sediment density coupling and considers fine sediment flocculation and fluid mud bottom boundary layer. Results show that the typhoon remarkably enhances wave-induced bottom stress but slightly increases current-induced bottom stress. Increased wave-induced bottom stress led to intensified sediment resuspension, subsequently increasing suspended sediment concentration (SSC) and SSF during the typhoon. Typhoon wind fields primarily impact sediment transport, with large wave impacts on both the south and north banks, while the effect of air pressure was negligible. The tide-induced net SSF was eastward. Residual currents magnitudes and SSC were positively correlated with typhoon intensity. Tide-surge nonlinear effects decrease the SSC. By decomposing the net SSF, the Euler transport term (<em>T</em>₁) and the tidal trapping effect (<em>T</em>₄) were the main terms among 7 components. The winds promoted sediment transport mainly through <em>T</em>₁ and <em>T</em>₄. For wave-induced sediment transport, <em>T</em>₄ was the main term. The tide-surge nonlinear interaction suppressed surge-induced sediment transport through <em>T</em>₁ and tide-induced sediment transport through <em>T</em>₄.

So, we investigated how carbon stock changes across four different aged of <em>S. apetala</em> plantation forests (8, 16, 24, and 32 years) in the Chakaria Sundarbans. Twenty representative plots (20 m × 20 m) were selected from 4 different stand ages (8, 16, 24, and 32 years) using stratified random sampling design (SRSD) method. Soil organic carbon (SOC) content from 0 to 30 cm soil layers, aboveground biomass (AGB) and belowground biomass (BGB) were studied to calculate the total carbon stock (TCS). A positive correlation was observed between TCS and stand age. The TCS at the 8, 16, 24, and 32 years old plantation sites was 60.85, 109.73, 136.29, and 183.48 t ha⁻¹, respectively.

For this reason there is an increasing need for studies that integrate solutions based on the nature of agreement and social perception, especially that of the users of the environment. The aims of the present work are to understand the historical evolution of the beach, analyze its current conditions, and offer applicable management proposals to balance tourism demands with geoconservation principles for sustainable coastal management. In this sense the Martianez beach in Tenerife (Canary Islands, Spain) exemplifies these challenges, as the beach has faced continuous transformations over several decades due to urbanization and management interventions. The methodology of this research included granulometric analyses of sediment collected between 2023 and 2024, a review of historical sources, aerial photographs and orthophotos, a wave dynamics study, and use of a digital shoreline analysis system. Additionally, visitors' reviews on Google Maps were analyzed. The historical evolution of Martianez beach revealed significant transformations over time. Sedimentological patterns are not homogeneous on the beach, with significant differences detected that could be related to beach transformations or beach regeneration. The digital shoreline analysis system (DSAS) showed significant variability in shoreline changes. High shoreline change envelope (SCE) values (10.34 m to 32.41 m) indicate regions of substantial erosion or accretion. Negative net shoreline movement (NSM) values (-23.73 m to −5.75 m) reflect a general trend of shoreline retreat. The range of end point rate (EPR) values (-18.45 m to −0.64 m per year) shows that the southern sector is experiencing more rapid erosion than the northern sector. Based on visitors' reviews, it was found that while the beach offers a scenic and natural landscape and convenient amenities, positive aspects such as its black sand and excellent surfing conditions are counterbalanced by significant drawbacks highlighted in negative reviews. Concerns regarding safety due to rocky outcrops, strong currents, and inadequate rental amenities detract from the overall appeal of the beach. This research could contribute to the development of effective governance tools for sustainable climate change adaptation decisions.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":"84 ","pages":"Article 104100"},"PeriodicalIF":2.1,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The present study assessed how different components of total effort have changed from 1985 to 2024 and how different components of effort influenced an estimate of relative fishing mortality (F_proxy). F_proxy could be predicted from a combination of the number of boats participating in fishery, the average number of gillnets hauled per day, the average number of fishing days utilised in the season and an index of under/over estimation of the biomass index. Time period was also included in the model as there was a change in the catch per unit effort (CPUE) at a given level of biomass index from 2004 to 2005 when limits on the number of fishing days pre boat was introduced. The number of boats with a licence to participate in the fishery currently exceeds the capacity of the fishery, thus if the number of boats were to rise to historical highs, then F_proxy would rise above the management target. Total catch is primarily managed through the number of consecutive days a boat can fish for, however, the number of boats has a greater impact on fishing mortality than the number of fishing days. We present a model which can predict F_proxy for a given level of effort, but this requires the number of boats which will participate in the fishery to be known. In terms of maintaining fishing mortality within sustainable limits, the effort system could be considered to be successful. However, the management of this fishery is now changing to an output-controlled fishery, but the experience from this fishery serves as a good model for other fisheries where management systems have a limited capacity to control catch.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":"83 ","pages":"Article 104105"},"PeriodicalIF":2.1,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The model included 19 functional groups, ranging from primary producers to top predators. Bacteria were also considered in this ecosystem model. The results indicated that the trophic level of the SCZ ecosystem ranged from 1.000 to 4.820, with a mean trophic level of 3.743.
