Abstract:

This paper presents the results of the planform stability classification for the headland-bay beaches of the State of Santa Catarina and of the Northern Coast of São Paulo, based on the application of the Parabolic Bay-Shape Equation (PBSE) to aerial images of the beaches, using the software MEPBAY®. For this purpose, georeferenced mosaics of the QuickBird2® satellite imagery (for the State of Santa Catarina) and vertical aerial photographs (for the northern coast of São Paulo State) were used. Headland-bay beach planform stability can be classified as: (1) in static equilibrium, (2) in dynami

Abstract:

To position the tourism offering of the Municipality of Lovran, it must be adjusted to the modern needs of tourists. In this, a key role belongs to designing, implementing and sustaining an experience system as part of the destination’s integrated tourism product. Lovran as a tourist destination can become distinctive only to the extent to which it can provide services and facilities capable of satisfying the travel needs and motivations of tourists. When designing an experience system, the destination is generally in the focus of interest. This paper, however, takes a closer look at the thema

Abstract:

Marine plastic debris (MPD) is a globally relevant environmental challenge, with an estimated 8 million tons of synthetic debris entering the marine environment each year. Plastic has been found in all parts of the marine environment, including the surface layers of the ocean, within the water column, in coastal waters, on the benthic layer and on beaches. While research on detecting MPD using remote sensing is increasing, most of it focuses on detecting floating debris in open waters, rather than detecting MPD on beaches. However, beaches present challenges that are unique from other parts of

In order to identify how research contributes to the knowledge of marine litter as a pressure on beaches, we reviewed interactions of beach fauna with this pollutant. Entanglement of pinnipeds in fishing gear, negative correlations between macroinvertebrates abundance and sediment pollution, and the presence of plastic surrounding burrows were primary evidence of beach fauna interacting with stranded litter. Ingestion represents the main body of research; microplastic uptake by invertebrates has been studied by laboratory experiments and field collections to report the presence of polymers in

Abstract:

Sandy-muddy transitional beaches (SMT-Beaches) consist of an upper sand shoreface and a lower mudflat, connected by a distinct sand-mud transition (SMT) boundary. The formation and development of SMT-Beaches require unique geological and dynamical conditions. Therefore, SMT-Beaches receive less attention compared with sandy beaches or sand-gravel mixed beaches. SMT-Beaches are mainly supplied with the sediments originating from e.g., river mouths, and the mud finally deposits on the intertidal or subtidal zone (Anthony and Dolique, 2004). The position of SMT boundary depends on the hydrodynami

Sampling at stations representing several degrees of oiling and treatment disturbance showed that hydraulically washed beaches had significantly lower clam densities in 1990.

Sea turtles are an important part of marine and coastal ecosystems around the world. Yet, six of seven sea turtle species are endangered (IUCN, 2021). While they spend most of their lives at sea, female turtles use sandy beaches as nesting habitat, where they dig their nests in the sand to incubate for up to two months. A major challenge to sea turtles is the degradation of their nesting beaches due to anthropogenic climate-change effects, such as accelerated sea level rise (SLR) and anomalous storm activity.

Abstract:

ABSTRACT Gravel beaches are the most difficult of all the beach types to clean and restore after an oil spill. Thus, they rank the highest of beaches on the environmental sensitivity index scale (ESI = 6). Problems posed by gravel beaches include: high porosity and permeability that allow deep penetration from the surface; potential for deep and rapid burial by clean sediments; presence of localized, sheltered areas where oil can persist for years; complex patterns of sediment reworking during storms; and slow rates of natural replenishment. Cleanup techniques currently employed on such beache

Abstract:

We examined the benthic macroinfauna at three strata during two seasons (winter and summer) on two sandy beaches (dissipative and reflective) in south-eastern Brazil. The hypothesis raised is that effects of morphodynamics and zonation determine the structure of macroinfauna, with dissipative beaches having comparatively higher species richness and density than the reflective beaches. Flamengo beach (dissipative) had higher species richness but lower density compared to Grumari beach (reflective). A high dissimilarity in assemblage structure (91.75%) was detected between the two beaches. Zonat

Abstract:

Abstract Taiwan is surrounded by oceans, and therefore numerous pleasure beaches attract millions of tourists annually to participate in recreational swimming activities. However, impaired water quality because of fecal pollution poses a potential threat to the tourists' health. This study probabilistically characterized the health risks associated with recreational swimming engendered by waterborne enterococci at 13 Taiwanese beaches by using quantitative microbial risk assessment. First, data on enterococci concentrations at coastal beaches monitored by the Taiwan Environmental Protection Ad

Abstract:

This study examines the spatial distribution of the ghost crabs, Ocypode quadrata Fabricius, 1787, in thirteen estuarine sandy beaches located along two main axes of the Paranaguá Bay Estuarine Complex, southern Brazil. Burrow densities of ghost crabs were measured at three beach levels established around the high tide mark during the summer and winter of 2005. All beaches showed a steep beach face slope (2.6 to 8.3º) with sediment composition varying from well sorted fine sand to very poorly sorted coarse sand towards the upper estuary. Water salinity ranged from around 31 at those beaches ne

Abstract:

Macrofaunal community composition of ten exposed sandy beaches in northern New South Wales, Australia, appeared to correlate with beach morphodynamic state even though the data represented sampling at only a single time. Better results were obtained by using the Beach State Index (BSI) rather than the dimensionless fall velocity (?). Species number and abundance significantly increased as the BSI value increased, whereas biomass was not correlated with BSI. The New South Wales beaches had a higher species number and abundance relative to BSI than did beaches in a published review of beaches ar

Abstract:

This paper deals with the breaker height on non-uniformly sloping beaches. A large number of experiments were carried out to obtain a breaking criterion on bar and step-type beaches. Based on the experimental data, a relationship among the breaker height, water depth, and wave period is investigated for various bottom configurations. As a result, the breaker height on non-uniformly sloping beaches is found to be well predicted by substituting an equivalent bottom slope in Goda's breaker index which has been obtained for uniformly sloping beaches. The equivalent bottom slope is defined as the m

Abstract. The majority of drowning deaths on Australian beaches occur significant distances away from lifeguard services. This study uses results of 459 surveys of beachgoers at five beaches unpatrolled by lifeguards in New South Wales, Australia, to improve understanding of who visits these beaches and why, and to identify risk factors associated with their beach safety knowledge and behaviour. Many unpatrolled beach users were infrequent beachgoers (64.9 %) with poor rip current hazard identification skills, who did not observe safety signage that was present, and yet intended to enter the w

Abstract:

Plastic pollution in the ocean is an emerging environmental concern in the Philippines. This study was conducted to investigate the prevalence of macroplastics, composition of plastic litter, and the clean-coast index (CCI) of urban and rural beaches in Sarangani Bay. Plastic litter was collected by delineating a 100-m transecting line with three 4 m × 4 m quadrats. The density of macroplastic litter in urban areas (0.66 items m−2) was significantly higher than in rural areas (0.29 items m−2). The plastics sampled were predominantly food packaging, such as polyethylene bags, which are locally

This study aimed to characterize the temporal and spatial occurrence of microplastics on the beaches of the Caribbean coast of Limón, Costa Rica. The selected beaches comprise a stretch of 70 km, characterized by large environmental protection areas, agricultural and residential areas with low occupation density, urban areas, and port areas. Despite the great importance of the beaches for the country, studies related to solid waste pollution remain scarce on the Caribbean coast. The methodology consisted of conducting fieldwork in 2017 and 2019 to collect materials on five beaches and laborato

Characteristics of plastic debris were assessed among two types of beaches on Bawean Island (windward and leeward) to analyze its sources and long-term effects. Plastic debris was collected inside a 5 x 5 meter transect with five transect plots on each beach per 20 meters. Samplings were carried out three times at intervals of seven days from six different beaches. The average abundances of plastic debris were almost similar between leeward (0.169±0.123 pcs m-2) and windward beaches (0.841±0.577 pcs m-2). On the other hand, in terms of weight, leeward beaches contained a very low value of debr
