Authors: Ntakirutimana Remy , Syanya Fredrick Juma , Mwangi Paul
Published: September 2023

As global demand for fish as a food source continues to rise, addressing challenges within the aquaculture industry and meeting consumer needs becomes imperative. Enhancing fish growth and safeguarding against microbial pathogens are among these challenges. Understanding the intestinal microbiome holds promise for achieving these goals and benefiting the aquaculture sector with a particular focus on tilapia, which has gained increased attention in recent research. Probiotics, live microorganisms administered at appropriate levels, can foster a balanced gut microbiota in animals. This can yield advantages like pathogen defence, improved digestion, enhanced growth, and increased survival rates in Tilapia. Probiotics are emerging as tools to promote healthy intestinal environments in Tilapia and other fish species, with potential to positively influence gut structure, ecosystem, growth, and disease resistance. The dynamic interplay between tilapia and their intestinal microbiota has garnered significant attention, affecting tilapia's health, performance, and overall well-being. This review compiles research findings on the influence of probiotics on tilapia intestinal ecosystems, morpho-histological structures, and enzymatic activities. It outlines their impact on gut microbiota composition in tilapia, demonstrating their ability to increase beneficial bacteria while reducing pathogenic strains. Probiotics can enhance intestinal morphology in tilapia, promoting villi development, goblet cell density, and mucous layer thickness. Additionally, they influence digestive enzyme activity in tilapia, resulting in improved nutrient absorption and tilapia growth. Although this field is continually evolving, the progress in deciphering probiotics' complex interactions with tilapia guts underscores their potential benefits in advancing tilapia aquaculture practices.

Authors: Feng Chunhua
Published: September 2023

In this paper, the oscillation of the solutions for a Parkinson's disease model with multiple delays is discussed. By linearizing the system at the equilibrium point and analyzing the instability of the linearized system, some sufficient conditions to guarantee the existence of periodic oscillation of the solutions for a delayed Parkinson's disease system are obtained. It is found that under suitable conditions on the parameters, time delay affects the stability of the system. The present method does not need to consider a bifurcating equation. Some numerical simulations are provided to illustrate our theoretical prediction.

NAC proteins, part of the largest plant transcription factor family, play pivotal roles in plant development, and biotic and abiotic stresses. Among them, the SlNAC1 protein in tomato serves as a Negative regulator, enhancing tolerance to cold, bacterial, and viral diseases. However, our knowledge of SlNAC1 protein in silico analysis, evolutionary relationships, and protein interactions remains limited. We used in silico tools to study the SlNAC1 protein in tomato. Phylogenetic analysis showed it is closely related to other Solanaceae family members. Motif analysis revealed seven conserved motifs shared among Solanaceae members. The presence of NLS confirms its abundance in the nucleus. Protein-protein interaction analysis predicted ten potential nuclear partners, including five uncharacterized proteins and others involved in plant development. In silico expression, analysis showed abundant SlNAC1 presence in both fruit and roots. This study provides the role of SlNAC1 protein in tomato, shedding light on its evolutionary context and    protein interactions.

Published: September 2023

Introduction: Teeth whitening is the most sought after aesthetic conservative treatment by patients, however, one of the side effects is the sensitivity caused by the technique. To promote the reduction of post-bleaching sensitivity, different presented and systemic protocols were presented. However, it is clear that there is still no desensitizer that controls tooth sensitivity during and after bleaching.

Objective: To summarize the available evidence on the efficacy of desensitizing agents on dentin sensitivity following tooth whitening.

Sources: On September 04, 2021, a comprehensive search of MEDLINE via PubMed, EMBASE, LILACS (Latin American and Caribbean Health Sciences Literature), LIVIVO, SCOPUS, Web of Science, and the gray literature by Google Scholar was performed.

Study Selection: After removal of duplicates, title, and abstract screening by two reviewers (performed in the Rayyan tool for systematic reviews), 13 articles were included, selected only blinded randomized clinical trials, which present patients with discolored teeth submitted to in-office and/or home tooth whitening and desensitizing agents used. The following data were collected: authors, year of publication, objectives or research questions, desensitizing agent, number of participants, number of groups, control group description, study group description, whitening approach, outcomes evaluated, main results, main conclusions, the scale used for outcome measurement, risk of tooth sensitivity (outcome), statistical test used, odds ratio/IC results, dentin sensitivity intensity analysis (intergroup statistical test), dentin sensitivity intensity analysis (intragroup statistical test), and maximum analysis time. After applying readability criteria, a total of 11 articles were deemed suitable for inclusion in the meta-analysis. The overall analysis demonstrated a statistically significant difference in the impact of desensitizing agent use, with lower dental sensitivity scores observed compared to placebo treatment (p = 0.036, 95% CI: -0.273; -0.009).

Conclusion: Based on the findings of this study, it was possible to verify that the desensitizing agents acted significantly reducing tooth sensitivity and the odds-ratio of patients submitted to in-office tooth whitening.

Authors: Ester Livia
Published: September 2023

This research seeks to study the use of address terms in a business talk. Address terms such as FN, LN, T, TLN, KT, PN, or Miscellaneous, are selectively used to address others depending on some social factors such as age, gender, social occasions, social relationship, family relationship, occupational hierarchy, as well as racial background. This research studies qualitatively the utterances of Thomas Shelby, the main character in Peaky Blinders. The findings show that Thomas Shelby only uses FN, TLN, and Miscellaneous, such as person deixis and zero address term. Therefore, in a business talk, a speaker may choose the use of appropriate terms of address in accordance with the social factors to maximize communication’s purposes.
SPATIAL VARIABILITY IN BEACH-FACE SLOPES FROM SATELLITE REMOTE SENSING
Authors: Vos Kilian , Deng Wen , Harley Mitchell D. , Turner Ian L. , Splinter Kristen D.
Published: September 2023

The beach face is the most seaward region of the dry beach. This region is the primary interface between land and ocean, and therefore has a great influence on coastal processes such as the exchange of sediment between land and sea or the reflection of wave energy at the shoreline. In particular, the slope of the beach-face, is an important parameter in coastal engineering to calculate the vertical and horizontal excursion of wave run-up (Stockdon et al., 2006). Yet, despite the importance of the beach-face slope parameter in many formulations used by coastal engineers, this quantity remains poorly mapped along the world’s sandy coastlines and the absence of large-scale datasets of beach-face slope is presently limiting our ability to deploy coastal inundation forecasting systems (O’Grady et al., 2019). This work describes a novel methodology to estimate beach-face slopes with satellite remote sensing and presents large-scale datasets of beach-face slopes along open-coast sandy coastlines around the Pacific Rim.

Published: September 2023

The Corpus Christi Ship Channel in Texas connects the Port of Corpus Christi to the Gulf of Mexico. The Port is seeking to deepen the Corpus Christi Ship Channel to 22.9m (75ft) nominal depth in order to allow fully loaded very large crude carriers (VLCC’s) to access proposed terminals within the port complex. As a part of the environmental coordination requirements of the National Environmental Policy Act (NEPA) the Port Authority prepared a number of studies to assess the potential environmental impacts of the proposed channel deepening. These included assessing changes in hydrodynamics, salinity, storm surge, and sedimentation patterns including sediment movement generated by vessel generated currents. The channel design was also verified through vessel maneuvering studies which were conducted using modeled currents, dynamic underkeel clearance assessment, and propeller scour potential determination. The fate of proposed beneficial use of dredged materials to construct a submerged beach berm and perform beach nourishment was also assessed.
TYPHOON JEBI-INDUCED FLOOD MODELING DUE TO WAVE OVERTOPPING/RUNUP AND REVERSE FLOW AT KANSAI AIRPORT
Authors: Jo Junbeom , Kim Sooyoul , Mase Hajime , Mori Nobuhito , Tsujimoto Gozo
Published: September 2023

Typhoon-induced high waves and precipitations cause severe flood damage in low-lying coastal areas. Typhoon Jebi (2018) induced a compound flood at Kansai Airport by stormy waves, and seawater reversed flow through sewer systems. However, the cause of damage at Kansai Airport has been presented incompletely in various studies that analyzed individual flood factors and simply summed each result. A valid method for simulating the compound flood has not yet been established due to insufficient discussions. It means that we might encounter serious difficulties in adequately addressing the potential compound flood risk in the future. Therefore, this study validates the applicability of the compound flood simulation model by reproducing the flooding process of Kansai Airport. A series of numerical experiments were conducted to reproduce Jebi-induced inland flood at Kansai Airport by using a coupled coastal flood model of the storm surge, high wave, wave overtopping/runup, precipitation, and sewer backflow (Jo et al., 2021).
SHORT TERM SPATIALLY DENSE PREDICTION OF STORM SURGE ALONG THE NEW ZEALAND COASTLINE

Published: September 2023

Storm surge is the rise in water level generated by wind and atmospheric pressure changes associated with tropical or mid-latitude storms. In conjunction with tides, it is one major driver of coastal flooding associated with storms events. Because local inundation is strongly modulated by the local shape of the coastline and the bathymetric slope, accurate storm surge prediction by the mean of traditional numerical models requires the use of very fine grids and is hence very resource intensive. This means that the performance of a live prediction system based on such methods will likely be subject to a trade-off between prediction accuracy, prediction speed and cost (Wang et al., 2009). Several publications have demonstrated the potential of machine learning approaches for the prediction of storm surge (e.g. (Tiggeloven et al., 2021), (Cagigal et al, 2020)). However, the developed methods often focus on local predictors and aim at predicting storm surge at a single location at a time. In this study, we explore the use of several data driven methods as an alternative to numerical methods to predict storm surge along the coast of New Zealand.
THE EFFECT OF TROPICAL CYCLONES’ TRANSLATION SPEEDS AND LANDFALL ANGLES ON MAXIMUM SURGE HEIGHTS ALONG IDEALIZED COASTS
Authors: Qian Xiaojuan , Son Sangyoung
Published: September 2023

Global warming has known to alter the cyclonic translation speed (TS) in the past, for instance, a slowdown trend of TS in the Northwest Pacific region. Thus, the importance of TS along with landfall angle (LA) has been examined over the coast of Louisiana (Rego, 2009). Not only these cyclone’s characteristics but also the geometries that the cyclone is traveling over are found to be crucial to the development of storm surge. Meanwhile, previous studies mainly focus on one or two individual characteristics in specific sites, which made their conclusions limitedly understood. Therefore, this study aims to generalize the synthetic effects of TS, LA, and coastal geometries on a maximum surge height (MSH) along the coast through the numerical simulations of a series of idealized scenarios.

Highly touristic activities, fishing and trade shipping coexist along the Pacific coast of Central America, the last one dominated by the Panama Canal. Then, an accurate spatio-temporal characterization of wave climate is of utmost importance and relevance. Notwithstanding, the existence of various wave models over the Pacific Ocean, such models offer information under spatial resolution of 0.2° at most and three hourly temporal resolution. Several WavewatchIII ® (WW3 Group, 2019) parametrizations have been adapted to the Central American Pacific coast, obtaining results which differ from each other.
TEST OF LSTM NETWORKS IN LONG-TERM BEACH MORPHOLOGICAL CHANGES
Authors: Banno Masayuki , Kuriyama Yoshiaki
Published: September 2023

In the prediction of beach profile changes, for example, the long-term calculation of daily changes can only provide sufficiently reliable reproduction results for a few years. One of the reasons is that actual morphological change is caused by the superposition of complex processes that are unknown. The prediction of timeseries data by data-driven models in contrast to physical models has been applied to various fields in recent years with the spread of deep learning and is expected to be used as a tentative solution for problems that cannot be adequately predicted by physical modeling. Recurrent neural networks are being applied to predict shoreline change over several years (Montaño et al., 2020), but application to spatial morphological changes, such as beach profile changes, is rarely investigated due to the limitations of the large amount of observation data required for learning. Here, we used the LSTM (Long Short-Term Memory) network, one of the recurrent neural networks, and long-term beach profile data observed at the Hasaki coast, Japan for learning and prediction of beach profile changes.

Published: September 2023

All around the world, deltas are among the most densely populated and heavily utilised regions, where crucial functions, such as freshwater availability and safety against flooding, strongly relate to the natural dynamics of the system. Therefore, a thorough understanding of the estuarine system is crucial, especially when developing nature-based solutions for safeguarding these essential functions for today’s society as well as future generations. To better understand the effect of different estuarine parameters on salt intrusion, an extensive sensitivity analysis has been executed based on an idealised estuary layout. The idealised estuary is parametrically designed using thirteen parameters that represent both boundary conditions and geometric features, such as river discharge and water depth. Subsequently, the Delft3D Flexible Mesh (DFM) model has been used to determine the salt intrusion, allowing the exploration of a wide range of estuary layouts.

Typhoon Rai, the last typhoon in the Western Pacific basin in 2021, entered the Philippine Area of Responsibility (PAR) on the 14th December at 23:00 Philippine Standard Time with a minimum central pressure of 985 hPa and maximum sustained winds of 100 km/h (NDRRMC 2022). The typhoon made its first of nine landfalls at Siargao Island in Surigao del Norte on the 16th December 2021 13:30 PST and continued to bring strong winds and rainfall to the Visayas region. The storm was one of the strongest typhoons to have hit the Philippines in recent times, and the government declared a State of Calamity across 493 cities and municipalities (NDRRMC 2022). The typhoon damaged more than 1.1 million houses in the Central Visayas region, and caused a total of 220 total reported deaths and 546 injuries. In the present work, the authors surveyed the storm surge heights in a variety of coastal areas of Cebu and Bohol islands.
QUANTIFYING AND CLASSIFYING COASTAL CHANGE IN SCOTLAND USING SATELLITE-DERIVED COASTAL BOUNDARIES
Authors: Muir Freya M. E. , Hurst Martin D. , Richardson-Foulger Luke , Rennie Alistair F.
Published: September 2023

Global sea levels and the frequency and severity of coastal storm events are both predicted to rise with anthropogenic climate change. Coastal storms are often accompanied by intense wave energy producing large waves which lead to impact damage, wave overtopping and flooding of coastal infrastructure Erosion of soft coasts can cause instability and infrastructure damage, and exacerbate flood risk with weakening of natural protective features like dunes. To plan effectively for a changing climate and increased coastal risks, coastal managers require continuous, repeatable datasets on past coastal change to anticipate potential future changes and assess adaptation options.
SEASONAL HYDRODYNAMICS AND TRANSPORT TIMESCALE OF A COASTAL ISLAND
Authors: Silva Larissa Maia Dantas da , Guimarães Ricardo , Fonseca Richardson Gomes da , Rosman Paulo Cesar Colonna
Published: September 2023

Santa Catarina Island, situated at the city of Florianopo-lis has over 450000 people and is the 2nd most populous island in Brazil, with 88km of sandy beaches. Located between the island and the continent are the North and South Bays, with an average depth of 5m. The Southeastern Brazilian coast is constantly affected by the passage of frontal systems remotely generated on the Argentine continental shelf. These remote signals can induce shelf waves with periods of several days, playing a key role in mean sea level (MSL) variations (Castro and Lee, 1995). Remote winds blowing parallel to the Southeastern Brazilian coast from the south quad-rant tend to increase the mean sea level, while winds from the north quadrant induce a lowering of the MSL. Consequently, these sea level fluctuations may generate coastal currents that are dissociated from the astronom-ical tide, with heights in the same order of magnitude as the astronomical components (Melo et al., 2016; Dottori and Castro, 2018). To provide useful information, this paper aims to de-scribe the coastal hydrodynamics and assess the transport timescales of Santa Catarina Island, including the North and South Bays. To represent seasonality, two scenarios comprising 3 months each - winter and sum-mer - were defined, with different meteorological and hydrological conditions.
INSHORE TSUNAMI HAZARD INCLUDING BATHYMETRIC AND EPISTEMIC UNCERTAINTY – A DESIGN METHODOLOGY
Authors: Couper Zachariah , Waterhouse Alex
Published: September 2023

Probabilistic Tsunami Hazard Analysis (PTHA), as detailed by Thio et al (2005) amongst others, can be considered a conceptually standard approach to assessing tsunami hazard, as discussed by Geoscience Australia in the Tsunami Hazard Modelling Guidelines (2018). Typically, hazard curves of a hydrodynamic parameter such as surge level are produced at an offshore location. This study presents a methodology which facilitates the production of inshore hazard curves which retain and account for complex hydrodynamic interactions, in addition to allowing uncertainty in bathymetry and model capture of seiching in local embayments. The methodologies are demonstrated through a case study of American Samoa, for which detailed bathymetry is available in the public domain, and high-resolution tsunami observations have been previously captured.

Published: September 2023

Sustainable coastal defense is promoted by wave-vegetation interaction that occurs in coastal zones and is able to dissipate wave energy and baffle currents. To study the complex fluid-structure interactions involved, numerical models present themselves as a suitable tool able to offer an in-depth view over the near field kinematics and dynamics. Taking into account the effect of vegetation dynamics is necessary, and often modelled through coupled fluid and structural solvers. This implies increased complexity, adaptive re-meshing tools, and numerically expensive simulations given the disparity between dimensions of the fluid domain and the very thin structural elements. The aim of this work is to present a novel numerical coupling tool based on the meshless Smoothed Particle Hydrodynamics (SPH) method, which can handle ultra-thin vegetation and resolve the vegetation kinematics without the use of any fitted parameters.
IMPROVING ANALYTICAL WAVE DAMPING MODELS FOR WOODY VEGETATION
Authors: Kalloe Su , Hofland Bas , Wesenbeeck Bregje van
Published: September 2023

Including vegetation in front of dikes is a promising addition to stand-alone hard infrastructures for the safety against flooding. Vegetation dampens the incoming waves, alters velocity structures and enhances sedimentation. Besides this, it provides other ecosystem benefits such as increasing biodiversity and scenic values. However, these cannot be implemented yet as we need more accurate ways of predicting wave damping, especially during storm conditions. We need both hydraulic and vegetation measurements, where the latter is difficult for woody vegetation as they consist of more complex structures (i.e., branch densities, angles and tapering) than grassy vegetation. Part of the Woody project aims to improve existing analytical models for wave damping by woody vegetation. We will mainly focus on accurate vegetation input (i.e., frontal-surface area and flexibility) as well as quantifying the impact of these parameters on wave damping, and how to implement this in small-scale physical models. Thereto we also aim to identify possible scale effects during scaled physical modelling. Finally, these findings will be implemented in existing analytical formulations.

ARE GLOBAL CHANGES IN WAVE AND STORM SURGE CONDITIONS CORRELATED WITH COASTAL EROSION/ACCRETION?
Authors: Ghanavati Mandana , Young Ian , Kirezci Ebru
Published: September 2023

Both satellite and reanalysis model data have shown statistically significant changes in global wave height in recent decades. It is often speculated that, if such changes continue in the future, they may have an impact on coastal erosion. A global study to investigate whether the observed changes in significant wave height have had a measurable impact on beach stability has, not however, previously been attempted. This presentation will bring together global datasets of changes in wave height, storm surge and coastal erosion over the last 30 years, to investigate possible links.
PREDICTING SHORELINE EVOLUTION IN A CHANGING WAVE CLIMATE
Authors: Ibaceta Raimundo , Kristen D. Splinter  , Mitchell D. Harley  , Turner Ian L.
Published: September 2023

Reliable predictions of shoreline evolution at a range of time scales both now and by end of the century are required for assessing coastal vulnerability in a changing climate. This is particularly important given the possible changes in regional wave climates and/or ocean water levels due to climate variability. To this end, much work has gone into the development of simple and efficient semi-empirical shoreline models that can be used to predict shoreline evolution over time scales ranging from seasonal to multi-decadal. An alternative is to use time-varying model parameters to improve model predictability at interannual timescales. Kalman filter techniques offer a framework to detect time-varying (or non-stationary) model parameters by adjusting them as shoreline observations become available. Ibaceta et al. (2020) implemented a dual state parameter Ensemble Kalman Filter (EnKF) within the shoreline evolution model ShoreFor (Davidson et al., 2013), and showed that this methodology is suitable to detect parameter changes that best hindcasted observed shoreline evolution. Additionally, they demonstrated that this observed parameter non-stationarity could be linked to the changing characteristics of the underlying wave forcing. The application of this methodology over long-term datasets now enables the parametrization and physical interpretation of the model parameters as a function of the multi-year variability in wave forcing, allowing for enhanced shoreline predictions out of the selected training period.

Published: September 2023

Nature-based solutions (NbS) for coastal protection has recently gained increased attention worldwide as a sustainable, economical and eco-friendly alternative to conventional grey structures, particularly under the threat of climate change (Temmerman et al. 2013). Wave energy dissipation by vegetation can be parameterized by the total horizontal force acting on the plant; expressed using a Morison-type equation considering only the form drag component (Dalrymple et al. 1984). Modelling wave-vegetation interaction is challenging in a laboratory environment (Lara et al. 2016) and it is difficult to accomplish a realistic representation of a plant’s biomechanical behavior and geometry using plant mimics or surrogates. Few studies have modelled real saltmarsh vegetation in large scale laboratory facilities (Moller et al. 2014; Maza et al. 2015) and quantified wave attenuation, particularly for engineered living shorelines (Maryland DoE, 2013). Further research is needed, particularly in the Canadian context, to investigate the capacity of different saltmarsh species to effectively attenuate waves and wave runup under storm conditions, to examine the plant’s drag coefficient and to bridge the gap to develop technical design specifications for the detailed design of living shorelines.

Extreme external forces such as associated with strong cyclones have often caused severe coastal erosions. Numerical simulation models have been employed for evaluating these coastal morphological changes (Roelvink et al., 2009). However, few studies focused on the morphological response caused by tropical cyclones under expected climate change. In this study, field surveys and numerical simulations were conducted to evaluate morphological changes caused by typhoon Lupit (2021) on Niigata coast. PGW (Pseudo Global Warming) methods under the SSP scenarios of IPCC AR6 were used to simulate morphological responses under expected climate change.

Quantifying subsurface velocity in the surf-zone beneath shoaling/breaking/broken waves is critical to accurately predict nearshore processes such as sediment transport [Hsu and Hanes, 2004]. The in-situ instruments designed to measure this velocity where waves break, such as velocimeters, routinely get buried, broken, or lost in the surf-zone. This limits our ability to collect field datasets of subsurface velocity in energetic wave conditions. To address this, we propose to build on known relationships that link subsurface velocity behavior to more easily observable surface signatures. Here, we collect the necessary surface and subsurface data to test the hypothesis that surf-zone surface measurements can predict subsurface velocity profiles extending to the bed.

This paper describes our findings from ecological surveys at several shoreline and beach enhancement projects in the Caribbean. Using standard fish abundance and diversity surveys and benthic habitat mapping protocols, we track how rock armour transitions from a barren substrate at installation to a diverse marine ecosystem over time. The ecosystem services provided by the rock armour have been evaluated and compare well with naturally occurring habitats. Using available economic benefit analyses, we estimate the value of these ecosystem services at various stages as the rock armour habitat matures.

It is projected that global mean sea level could rise up to 1 m this century with a strong regional pattern. It is estimated that 20percent of England’s coastal defenses could fail under just half this rise. Ambitious climate mitigation and adaptation plans may protect 400,000 – 500,000 people, but flood and coastal erosion risks cannot be fully eliminated. Building coastal climate resilience requires accurate wave overtopping prediction tools and nowcast information to prepare for and respond to coastal hazards. In Dawlish, SW England, a new monitoring system to measure concurrent beach level and wave overtopping conditions over a 1-year period was installed. The system obtains in-situ measurements of the inland wave overtopping distribution across a public walkway and railway line, and issues near real-time overtopping data to the British Oceanographic Data Centre, making it accessible online within 15 minutes of detection. This public web service also ingests near-real time wave and water level data from existing national coastal monitoring networks, providing a full dataset to validate and calibrate an operational wave, water-level and overtopping forecast system. Using these data, the numerical forecasts have been refined by incorporating recent beach levels to reduce the uncertainty in the wave overtopping predictions due to seasonal variability in the beach level at the toe of the sea wall.
STUDY OF STORM TIDE MODELING IN THE PEARL RIVER ESTUARY
Authors: Shen Edward Qiang
Published: September 2023

By reproducing storm tides during nine historical typhoons in the Pearl River Estuary against observations, this paper presents a data-model comparison approach to quantify the uncertainties of three parameters of Holland (1980) parametric wind model. The wind reduction factor that represents effects of mountains and skyscrapers surrounding the estuary may be estimated by finding the minimum RMSE in simulated storm tide peak elevation. The radius to maximum winds can be efficiently adjusted according to observed pressures through the exponential distribution of atmospheric pressure field; and the peakedness is verified on the basis of maximum wind speed versus pressure drop relations. By applying these parameters with the wind model, storm tides in the estuary can be effectively simulated, except for wind conditions where most of the estuary is within the maximum wind radius and winds there are significantly affected by the mountainous lands. Wave setups are noticeable when typhoons made landfall on the right bank of the estuary. As a prerequisite for good model performance, the grid size somewhere in a storm tide model should be smaller than the minimum spacing among soundings points at that location in order to effectively produce the model bathymetry described by the soundings data.

The city of Skive, located in West Jutland Denmark, is looking to develop a long term strategic urban development plan integrated with supporting climate adaptation pathways keeping Skive climate-proof for future conditions. In this study a Dynamic Adaptive Pathway Plan (DAPP) was used to investigate uncertainties with regards to future climate change and urban development. Similarly to uncertainties regarding climate change (e.g. Sea-level rise) and the associated change in risk, there is great uncertainty in the future development of the system (Skive) through a range of socio-economic variables. This will directly affect the solution space for climate adaptation. NIRAS, LYTT Architecture and Skive Municipality have developed a strategic urban development plan and investigated the implications and possibilities for climate change adaptation in Skive. It is one of the first fully developed DAPP processes in Denmark. The project illustrated the need for supporting uptake of dynamic decision making, the necessity of multi-disciplinary collaboration within the municipality, and the integration of land use considerations within the adaptation pathway development.

The present study aims to address the future projection of waves and storm surges of Tropical cyclones over the Arabian Sea, using the atmosphere-ocean numerical models and CMIP5 climate models. A Pseudo Global Warming (PGW) approach was utilised to implement the future climate and a WRF-FVCOM-SWAN framework was utilized to estimate the changes of a historical event in the future climate. The uncertainties included in different parts of the framework can lead to remarkable changes in this future estimation and are required to be addressed and quantified for a more appropriate estimation. Different factors such as forcing, boundary condition, and physics play a significant role in the uncertainties of wave and surge models. The study revealed that the wind forcing provided by the WRF model is the governing factor with the highest importance.

Onshore wind can significantly affect wave overtopping process and increase mean overtopping discharge. Thus, the wind should be an important variable in coastal design process. However, despite many researches have analyzed the influence of wind on the overtopping, there is still a lack of exhaustive knowledge about this phenomenon. To further analyze the wind effects, the CFD model FLOW-3D has been used to investigate wave overtopping at vertical seawalls. The single-fluid approach has been adopted, i.e. the presence of wind has been simulated via the wind shear stress on the sea surface. The main aim of this work is to verify the ability of this simplified numerical modelling to capture the macro-processes involved in the phenomenon of wave overtopping. The presence of wind shear stress has led to physically consistent results. It confirmed that as the mean overtopping discharge decreases, as the wind effect increases. Furthermore, numerical results have shown that the advection of water droplets behind the structure by the wind is the key mechanism for the enhancement of wave overtopping. Finally, by gathering numerical results and laboratory data carried out by Durbridge (2021), a new predictive formula to estimate the wind factor is provided.
WAVE OVERTOPPING AT DIKES AND BREAKWATERS UNDER OBLIQUE WAVE ATTACK
Authors: Gent Marcel R.A. van
Published: September 2023

The crest level of coastal structures such as dikes and breakwaters is often based on estimates of the amount of wave overtopping. One of the important parameters affecting wave overtopping is the angle of the incident waves since oblique waves can significantly reduce the amount of wave overtopping compared to perpendicular wave attack. Based on 3D physical model tests on dikes, rubble mound breakwaters and vertical caisson breakwaters, the influence of oblique wave attack has been evaluated. A new expression for oblique waves has been derived that can be applied for all tested structure types.
