Measuring the Fate and Natural Attenuation Potential of a Viscous Marine Fuel on an Artificial Beach Mesocosm

Shoreline oiling poses a risk to coastal ecosystems and resources. Understanding the natural attenuation potential and impact of different sediment types is important for choosing appropriate intervention strategies and priority areas following a spill. Simulated IFO-40 oil spills on artificial beach mesocosms were carried out using different sediment types: sandy beach and sandy tidal flat, under low energy tidal cycles over a 5-day period. Chemical and biological analysis of leachate and sediment was conducted to understand the movement of oil through these mesocosms. Rapid oil movement from the oil slick to the surface sediment layer was observed in the sandy beach enclosures, while slower oil movement was observed in the sandy tidal flat enclosures. Increased hydrocarbon dissolution was observed in the sandy beach enclosures, marked by higher concentrations of low molecular weight n-Alkanes (C12 − 15) and naphthalenes (C0 − 3) in sandy beach leachate compared to sandy tidal flat samples. Despite the increase in hydrocarbons, there were no major shifts in microbial communities observed in the leachate and sediment compartments for either sediment type. Both prokaryote and microeukaryote communities differed between the two sediment types, with little overlap between dominant sequences. Our results indicate that limited oil penetration occurs within sandy tidal flat shorelines resulting in oil accumulation suggesting that sorbent or vacuuming could be used as emergency response to minimize the environmental and ecological impacts of spilled oil.

Artificial Nourishment Schemes along the Polish Coast and Lagoon Shores between 1980 and 2020, with a Particular Focus on the Hel Peninsula

This article reviews the literature covering the period from 1965 to 2020 dedicated to the issue of artificial beach nourishment along the Polish coast, with a particular focus on the Hel Peninsula. The primary sources used in this work include 34 reports from unpublished case studies and projects implemented by the Department of Maritime Hydrotechnics, Maritime Institute in Gdańsk, between 1971 and 2020. This paper also presents detailed information about the total fill volume in cubic meters of dredged material deposited along the Polish coast and lagoon shores in 1980–2020. During these 40 years, approximately 40.5 million m3 of sediment was deposited along the Polish coast and lagoon shores. Particular consideration was given to beach fills along the Hel Peninsula, which was at actual risk of breaking in its basal and central sections after intense storms at the turn of 1988 and 1989. The survey materials collected enabled the assessment of the coastal morphodynamics of the peninsula under the Coastal Protection Program through the prism of changes in the fill volume along the coastal sections, which were replenished with material coming from submarine deposits. The peninsula’s stability was also assessed, taking into account the ongoing climate change. Moreover, this article discusses the proposed rules and terms for protecting the Polish coast by way of artificial nourishment.

Eko-kejuruteraan dalam Penerapan Pertahanan Pantai berasaskan Alam Semula Jadi

Climate change increases the threat of erosion and flooding along coastlines around the world. Engineering technologies are response to protecting coastal communities and related infrastructure becoming increasingly unsustainable in economic and ecological contexts. This issue has led proposal to restore natural habitats, such as sand shoals, saltwater swamp areas, mangroves, seaweed, coral reefs, and shellfish, to provide coastal protection in lieu of or to complement artificial structures. Often coastal management is faced with eroded coastal problems which require decision on the most suitable mitigation option to implement. In this short review article, the application of eco-engineering in nature-based coastal defense is discussed. The obstacle in taking on the naturebased coastal defences is because of the rigorous assessment of their effectiveness compared to artificial protection structures. The assessment of the latest evidence for the effectiveness of nature-based beach protection versus artificial beach protection and future research needs are discussed in this review. Future projects should evaluate the habitat created or restored for coastal defence for its cost-effectiveness compared to artificial structures under the same environmental conditions. A cost-benefit analysis should consider all ecosystem services provided by nature-based or artificial structures in addition to coastal protection. Research among scientists, coastal managers, and engineers are needed to facilitate the experiments needed to test the value of this coastal protection scheme and to support its use as an alternative to artificial structures. This research is urgently needed because the rapidly changing climate requires new and innovative solutions to reduce the vulnerability of coastal communities.

Modern problems of coast protection in Taganrog

On the instructions of the Government of the Russian Federation and the Ministry of Natural Resources of Rostov Region, in April-September 2023, the Southern Federal University and the Southern Scientific Centre of the Russian Academy of Sciences carried out a study on the topic “Comprehensive survey of the coastal territory with justification of necessary measures to prevent the collapse of the coastline of the Taganrog Bay of the Sea of Azov”. An assessment of existing coastal protection structures has been carried out within the coastline of the city of Taganrog. A total of 27 structures were examined, with a total length of10.8 km. The coastal protection of the city is represented by various types of structures (passive, active, non- traditional). It was found that 55.8% of the coastal defenses length are classified as emergency and extremely emergency and do not perform their coastal protection functions. The methods that are still used to protect the shores are ineffective, and they are often harmful. In this regard, there is an urgent need to develop a general scheme of coastal protection and environmental management of the coast of Taganrog. In recreational areas, it is necessary to plan the creation of artificial beaches with retaining structures. Regulated backfilling of the beach material should be provided. To protect industrial facilities and housing stock - the creation of stone-filled berms is required. It is necessary to dismantle ineffective coastal protection structures or overlap them with a stone filling.All coastal defenses where there is no possibility of slope planning must be put out to sea by creating beaches and rock-cast berms. The area of water, for a possible advance of the coastline towards the sea can be up to 200 m, considering the rate of coastal erosion in Taganrog 0.5-3 m/year for a period of 100-150 years.

Characterization of marine litter on the beaches surrounding Marchica Lagoon, Morocco

Marchica lagoon, a Ramsar site on Morocco's Mediterranean coast, has emerged as a prominent tourist destination within the Mediterranean region. However, the summer tourism is often accompanied by a rise in waste accumulation, especially on the surrounding beaches. The focus of this study is a detailed analysis of marine litter found on the beaches near Marchica Lagoon, specifically Al Mohandis, Bocana, and Nador Artificial Beach. The data collection for this study was carried out over a three-day period prior to the summer season in June 2023. The methodology adhered to the established protocols of the "Guidance on Monitoring of Marine Litter in European Seas." A total of 731 items of marine debris were collected from these three beaches, with an overall weight of 20395 kg. The composition of the collected debris revealed that polymer materials were the most prevalent, accounting for 81% of the total debris, followed by paper/cardboard (6.3%), metal (6.2%), processed wood (2.9%), glass/ceramics (1.9%), and cloth/textile (1.78%). The analysis indicates that the majority of the marine debris is associated with the activities of beach visitors. It is recommended that public awareness initiatives be implemented and solid waste management practices improved.

Interdependence in Coastal Tourist Territories between Marine Litter and Immediate Tourist Zoning Density: Methodological Approach for Urban Sustainable Development

The coastal strip, characterized by the urbanization of coastal tourist territories (CTTs), has expanded over decades through civil engineering, altering the shoreline dynamics and creating artificial beaches crucial for tourism. To examine the relationship between extensive land use in CTTs for tourism and residences and the presence of marine litter, a specific parametric study was conducted along the coast of Tenerife, the largest island in the Canary Islands. Due to Tenerife’s geographical location and exposure to the descending Gulf Stream flow, the coastal waters in the selected zone experience waste impact at both local and global scales. However, the presence of marine litter deposited by ocean currents is at a micro level and falls outside the scope of this report. This study parameterised urban reality in study areas, and the presence of macro waste has been parameterised using standardised units of measurement. This enables the establishment of source measurements that will contribute to preventative measures against this type of coastal pollution. The interdependence between tourist zoning, civil seafront engineering works along the seafront, and marine litter presence in inaccessible and visible areas for tourists requires a methodology to better understand waste origin and loading areas. This knowledge is crucial for an effective local monitoring system. A quantitative overlay reading methodology has been designed in the urban setting through calculations of urban densities, while examining the waste in these areas’ immediate infralittoral flooring through the use of visual underwater extraction. Anticipating the type and quantity of waste in each area will allow for the implementation of effective awareness, promoting action for preventative and corrective measures at the urban level. The results show a direct dependence between urban density and the presence of waste, as well as an equation that makes it possible to anticipate the amount of waste according to urban density and its relational vector. There is no discontinuity between them, as each area is affected by others to the extent that they establish the parametric continuity conditions determining each field. Therefore, it is possible to relate them beyond a one-on-one relationship. This approach fosters sustainable tourism development, reducing pressure on the sea and enhancing the utilisation of tourism revenues in measures to address waste-related challenges and promotes sustainable tourism development in Europe’s coastal regions.

Novel experiments on the dynamics of amphibious craft during surf zone transit

This article presents the results of a comprehensive experimental study of amphibious vehicle dynamics during surf zone transits. The motions and loads of multi-mode vehicles traversing breaking waves is relevant to operators, designers, and simulators seeking to extend the operation of existing and new platforms into the littorals. Here we present the results from a first-of-its-kind experimental campaign to quantify the dynamics of a free-running amphibious model during surf zone transit.The amphibious vehicle studied was the IIHR Model Quadski, a model-scale free-running craft prototyped at The University of Iowa. Testing was conducted in a wave basin facility, equipped with an artificial beach to produce model-scale breaking waves up to heights of 37 centimeters. Vehicle attitudes, wave elevations, and maneuvering inputs were recorded during repetitious crossings of varied wave conditions in outbound, inbound, and oblique transit trajectories.Analysis of high-level statistics and pairwise comparisons show that decreased momentum entering the surf zone from shore resulted in significantly longer transit times and additional wave encounters, even with equal waterjet thrust. Furthermore, vehicle dynamics during seaward transits were considerably larger in amplitude and shorter in period than landward transits.

Analytical studies of the dynamics of pocket beach

The beach site is located in the utmost northeastern part of the Nevskaya Bay. A boulder dam is built on the western side, which, however, fails to protect the beach from the effects of waves that cause longshore sediment transport. The planned construction of transverse beach–retaining structures outlines in the “Water Sports Base in Primorsky District” initiative, mightchange the current situation. This study objective is to predict the evolution of the coastal contour resulting from the planned construction in the next few decades. A natural analogue of such an artificial structure could be a pocket beach located between two natural promontories. The sediment equilibrium at this study location includes three main components: volumes of erosion, accumulation and bypassing. The results include the computed wave patterns and the movement of sediment along the shoreline. The lateral sediment transport diminishes notably over time, driven by the alteration of the shoreline contour and the reduction in the angle between the wave equilibrium and the coastal resultant. The erosion and accumulation volumes increase over time, but their rates slow down. The shoreline displacement becomes more prominent over time; however, the rates of erosion differ from accumulation. The shoreline is moving particularly fast in the first years after construction, and then the process slows down gradually. The introduction of artificial beach protection structures in the 300th Anniversary Park of St. Petersburg will considerably reduce both the pace of beach erosion and the affected area. However, the erosion process will not be completely halted.

Monitoring sediment transport pathways from an artificial nearshore berm, South Padre Island, Texas, USA, August 2018 to November 2019—Implications for coastal management

During August 2018 – November 2019, the transport pathways of dredge material from a specially constructed nearshore feeder berm were investigated as part of a collaborative study by the City of South Padre Island, U.S. Army Corps of Engineers–Galveston District, U.S. Geological Survey, Partrac GeoMarine Inc., and Texas A&M University, into the efficacy of beneficial use dredge material (BUDM) as a method of replenishing the beach profile and shoreface at South Padre Island, Texas with sediment. Dual-signature (fluorescent and ferrimagnetic) tracer particles, designed to be hydraulically equivalent to the dredge material, were placed on the berm, and a sampling program was initiated to monitor the spatiotemporal movement of tracer particles under the influence of the prevailing hydrodynamic regime. Wave and current data were collected and were used together with available metocean data to identify the forcing mechanisms of sediment transport; improved understanding garnered from the consideration of multiple datasets can be used to inform future coastal management decisions.Tracer analysis results indicated low magnitude, shoreward transport of dredge material from the berm and along shore transport in both northerly and southerly directions. Small amounts of tracer detected in beach face samples demonstrated connectivity between the constructed feeder berm and the shoreface. However, the generally low tracer concentration within beach face samples indicated low rates of sediment transport for berm sediments, and a low magnitude sediment transport pathway from the berm directly to the beach face, with possible storage of sediment in the nearshore bar system.Given that the berm was at or beyond the closure depth and considering the relatively weak prevailing near bottom hydrodynamic conditions, the potential for sediment to be mobilized and transported during the study period was generally low. Periods of higher energy waves, driven by north-northwest winds, were identified as a key driver of sediment transport but due to the infrequent nature of these events the sediment transport regime across the area of interest was temporally limited. Longshore movement of sediment was both north and south, mainly dependent on prevailing wind directions and resulting longshore currents.We discuss implications for coastal zone management and the use of feeder berms as an artificial beach nourishment mechanism to replenish sediments lost by coastal erosional processes. The insight into nearshore emplacement of material can be used by local governments and coastal managers to optimize the efficacy of berm emplacement and implement such schemes as a cost-effective nourishment option, or when onshore placement of material is not feasible.

TUMBLING EXPERIMENT FOR THE ESTIMATION OF ABRASION AND MASS LOSS OF COASTAL SEDIMENTS FROM AN ARTIFICIAL COARSE-CLASTIC BEACH

In order to assess the accretive or erosive pattern of a stretch of coast, it is essential to estimate its sediment budget, i.e. the quantification of all sources and sinks of sediments. The sediment budget is the basis of a reliable coastal management plan (Ruol et al., 2018). In fact, coastal erosion is usually the result of a negative balance of factors, both natural and anthropogenic, that operate on different scales, none of which may be considered the single cause. Recently, a massive abrasion rate of coarse-clastic sediments was documented in artificial nourished beaches. The mechanism is associated with both mild wave conditions and extreme stormy events, which could also induce chippings. This phenomenon could decrease the durability of nourishments (Bertoni et al., 2012 and 2016) and is usually not considered in the sediment balance. The mass loss due to abrasion can lead to errors in the analysis of erosive and accretive patterns after the nourishment and consequently to erroneous coastal management strategies. Moreover, the sediment grain size in a given beach (naturally present or selected for nourishments) is strictly related to the typical wave energy. The abrasion mechanism and the possible pebble chipping change the sediment grain size, which could become unstable and not adequate for the local wave climate. Based on the large cost of nourishments, which also require strong monitoring in the subsequent years, it is crucial to understand the abrasion and mass loss rates of the filling sediments to extend the life of artificial beaches as long as possible.

Performance based assessment of a small-scale artificially nourished beach

In coastal engineering studies, coastal protection procedures can be provided by hard and soft methods. Soft methods applied using the right techniques and methods are not only long-lasting but also adapt to the natural structure of the coast. This study aims to present monitoring the development of a small-scale artificial nourished beach between the groins for 15 months and analyze its performance. For this purpose, field studies were carried out with land and sea observations taken once before nourishment and at 8 different times after nourishment. The seabed and profile variations observed at different sections were analyzed after processing field data. For determining the characteristics of the natural beach and borrow area before nourishment a sieve analysis was done for sediment samples taken from the shoreline, beach face, and 1-m depth on the nourished area. Sediment transportation of nourished material was observed by monitoring the amount of material remaining in 3 sub-regions (a nearshore region between the groins - A, a region representing the seaward end of the groins - B, and a region offshore of the groins - C) in the nourished region over time. The relationship between this behavior and waves was examined by considering the wave roses and time series of wave parameters produced as a result of wave simulations performed with the third-generation wave hindcast model SWAN. Lastly, as well as the variation of the mean layer thickness, the retreat of coastline, and mean beach width on the nourished area by the time were extracted for 8 different surveys. The results show that artificial beach nourishment materials were eroded in less than five months and the beach width returned to its initial position. The nourished material transported out groin-protected area moved eastward due to north-west dominated waves and the eastward longshore transport.

Microhabitat partitioning between sympatric intertidal fish species highlights the importance of sediment composition in gravel beach conservation.

Gravel beaches in the Mediterranean ecoregion represent an economically important and unique habitat type. Yet, burgeoning tourism, intensive coastal development and artificial nourishment of beaches may jeopardize their ecological communities. To date, species that reside on gravel beaches and the consequences of beach alterations are poorly understood, which hampers the development of a sustainable coastal tourism industry along the region's shorelines. Using a simple collection method based on dredging buckets through the intertidal section of beaches, we quantified the microhabitat association of two sympatric clingfish species in the genus Gouania at seven natural and an artificial gravel beach based on sediment characteristics. We hypothesized that slender (G. pigra) and stout (G. adriatica) morphotypes would partition interstitial niche space based on sediment size, which may affect the vulnerability of the species to changes in gravel beach composition due to coastal development. We detected substantial differences in gravel composition within and among the sampled beaches which suggests scope for microhabitat partitioning in Gouania. Indeed, we found significant relationships between species identity and the presence/absence and abundance of individuals in hauls based on their positioning on PC1. Our results suggest that modifications of gravel beaches through coastal development, including beach nourishment, intensifying coastal erosion, or artificial beach creation, may have detrimental consequences for the two species if sediment types or sizes are altered. We posit that, given the simplicity and efficacy of our sampling method and the sensitivity of Gouania species to prevailing gravel composition, the genus could serve as an important indicator for gravel beach management in the Mediterranean ecoregion.

Influence of Beach Erosion during Wave Action in Designed Artificial Sandy Beach Using XBeach Model: Profiles and Shoreline

Beach width is an important factor for tourists’ comfort, and the backshore is a swash zone where sediment moves quickly. Artificial sandy beaches focus on beach width stability and evolution. This paper is based on an artificial beach project in Haikou Bay, where, in view of the existing conditions, a new type of beach profile that can protect beach berm and width without being eroded by large wave action. Numerical simulation based on XBeach model were conducted to predict the morphodynamical responses of the beach, including a diagnosis of the erosion spots under storm and normal wave events, respectively. Sediment fluxes along and across the shoreline under varied scenarios, dependent on profile width and backshore slope, were discussed. It was found that normal waves with lower heights and longer periods can induce stronger erosion than storm waves due to the landform of the inner-bay in Haikou Bay. Engineering and biological methods to reduce beach erosion during wave action were discussed. Biological methods such as green-plants-root-system can retain berm surface sediment without allowing it to be transported offshore by wave action. The design concept of this artificial beach project may inspire more beach design and protection projects in coastal zones.

Wave Runup Prediction and Alongshore Variability on a Pocket Gravel Beach under Fetch-Limited Wave Conditions

Most empirical equations used for wave runup predictions have been developed from measurements at straight sandy beaches in unlimited fetch environments. While there are empirical equations to predict wave runup on gravel beaches, they have not been tested for prediction of wave runup on pocket gravel beaches, in limited-fetch environment, which can be found around Mediterranean. This paper addresses this lack of measurements on this type of beaches and examines the alongshore variability of wave runup. Wave runup measurements were made using video observations along 3 cross-sectional profiles on the pocket beach of Ploče, Croatia. The measurements have shown that the wave runup can vary for about 71% even around the centerline of the pocket beach. This variability is due to beach orientation and alignment of beach profiles to the prevailing wave direction, as well as difference in beach slope. Comparison of wave runup predictions from five well-known empirical equations and field measurements showed significant underprediction (up to NBIAS = −0.33) for energetic wave events, and overall high scatter (up to NRMSE = 0.38). The best performing wave runup equation was used for further refinement outside the original parameter space by including the Goda wave peakedness parameter (Qp). The newly developed empirical equation for wave runup reduced the NBIAS to 0 and the NRMSE by 31% compared to the original equation (developed equation metrics: R = 0.91, NBIAS = 0, NRMSE = 0.2, HH = 0.2 on the study site). This empirical equation can potentially be used for design of coastal structures and artificial beaches in similar environments, but further measurements are needed to test its applicability to a range of forcing and environmental conditions.

Assessing Tourists’ Preferences and Willingness to Pay for Artificial Beach Park Development and Management: A Choice Experiment Method

Artificial beaches have made a significant contribution to the expansion of coastal tourism. Obtaining information on tourists’ preferences for artificial beach tourism can help managers to better balance the relationship between the satisfaction of recreational needs and environmental protection. The Meishan Bay Beach Park in Ningbo, Zhejiang Province, China was used as the study site, and the tourists’ preferences for the artificial beach park development and management were evaluated using the choice experiment method. The results revealed that tourists were generally more interested in improving the governance level of the existing landscape than in further expanding the scale of artificial beach development. Among all attributes, significantly reducing the amount of garbage was the most preferred attribute, with a willingness to pay of 39.75 CNY, while willingness to increase beach area was the lowest attribute. The result of the preference heterogeneity analysis showed that tourists with higher education levels were more willing to pay to obtain a better recreational experience, while local tourists were more concerned about reducing congestion. Moreover, we found a clear and relevant segmentation of tourists’ choice behavior, with the strong sensitivity for raising the ticket price being driven by the smallest group of the sample.

Критерии технического состояния бетонных бун

The classical constructions of concrete boones on rocky and eroded bases used as part of engineering protection structures of the roadbed are considered. Concrete boones are designed to preserve the artificial beach and to create conditions for its formation. In order to determine the defects of both the structures as a whole and their elements, a survey of marine coastal protection structures (concrete boones) was carried out on the section of the Tuapse - Adler railway line of the North Caucasus Railway. Experimental studies of the interaction of waves with concrete boones and the beach on hydrowave models in a wave pool have been conducted. Criteria for the technical condition of concrete boone elements by types of defects have been developed. The division of concrete boones into individual elements according to the degree of weight is carried out. For each significant element of the coastal protection structure, criteria of technical condition by types of defects were obtained. In order to assess the technical condition of concrete boones and determine the necessary measures to ensure their operability, the algorithm is proposed in the form of a scheme. The development of quantitative indicators enables to assess the technical condition of concrete boones and, thus, improve the operation safety of the railway track on the pressing offshore sections. The proposed criteria are taken into account in the development of GOST R 59241-2020 «Coastal protection structures. Rules of inspection and monitoring of technical condition».
