Beach rescue statistics and their relation to nearshore morphology and hazards: a case study for southwest England. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 1 – 6. Gold Coast, Australia, ISSN 0749.0208 The coasts of Devon and Cornwall in the southwest of England experience some of the most energetic wave conditions (Hs,10% = 2–3 m) and largest tide ranges MSR = (4.2–8.6 m) in the UK. They are also a popular tourist destination during the summer months with over 10 million visitors per year. The energetic wave/tide conditions pose a considerable physical risk to beach users and 62 beach environments in this region are therefore patrolled by Royal National Lifeboat Institution (RNLI) lifeguards. Beach rescue statistics collected by the RNLI during spring and summer (1 May to 1 October) were analysed to examine and quantify the risk posed by physical beach hazards to beach users. Rip currents were found to be the main hazard and were responsible for 71% of all recorded incidents. The most hazardous beaches were found on the exposed west coast of the study area. Beaches here can be classified as morphodynamically intermediate and are characterized by low-tide tide bar and rip systems, often topographically-constrained by intertidal geology. The rip currents are generally most active around low tide. Beaches in Devon and Cornwall exhibit morphologies that are significantly different from previously studied beaches in Australia due to the combination of high energy surf zones, large tides and variable coastal geology. This work represents a first step towards the generation of standardized beach risk assessments in the UK.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140365201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 277 – 281. Gold Coast, Australia, ISSN 0749.0208 The development of a vertically averaged numerical model of an estuary in the coastal region of the Pacific Ocean on the east coast of Australia is described. The primary objective of the study is to provide a detailed picture of the tidal characteristics in the study area to enable the simulation of the whole water circulation within the water body. A comprehensive data set is collected as part of this study to understand local dynamics and to calibrate and validate the model. Calibration and validation have been achieved through a comparison of computed tidal harmonics against those derived from harmonic analysis of the measured water level variations. Also a comparison was made between the measured discharges across seven cross sections at critical locations in the study area with the discharge obtained through modelling. Calculations show that tides become mixed, mainly semidiurnal in the estuary. The study shows that for lunar constituents (M2 and S2) dissipation mechanisms are dominant and their amplitudes decrease along the estuary. Solar constituents (O1 and K1) experience an increase in amplitude. However, the net result is a reduction of tidal amplitude, indicating the dominance of dissipation mechanisms.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140365875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Management of Beach Carrying Capacity: The case of northern Portugal. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 135 – 139. Gold Coast, Australia, ISSN 0749.0208 The rapid growth of coastal tourism that has been seen in the last 40 years is frequently described as one of the major reasons for the development of these areas and also as responsible for many current coastal problems. The beaches perform, in this context, a fundamental role where the issues related to planning and management are increasingly more important when it comes to an implementation of a sustainable development philosophy. In these circumstances, concepts such as carrying capacity need to be used in a careful way. In Portugal, where coastal tourism plays a major part for the national economy, the management of beaches is crucial for maintaining their quality and therefore continuing to attract tourists. Since the 1990s, with the application of Coastal Zone Management Plans to the whole Portuguese coast, beach plans are now required. In those plans various parameters are considered, from the type and location of equipment and parking lots, to the definition of beach carrying capacity. This paper explores the results of the implementation of these plans to the beaches of northern Portugal. This part of the coast is very dynamic with high erosion rates. Some of the interventions from the Plans changed part of the characteristics of the beaches making it necessary, in some cases, to re-calculate the carrying capacities that were initially proposed, bringing new challenges to their management. This paper aims to stress the validity of the carrying capacity concept as applied to beaches, taking into account the need to use the concept in a flexible and dynamic way.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140366499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
