  • SST Ensemble Experiment-Based Impact Assessment of Climate Change on Storm
    • Authors: Junichi Ninomiya, Nobuhito Mori, Tetsuya Takemi, Osamu Arakawa
      Abstract: Coastal Engineering Journal, Volume 59, Issue 02, June 2017.
      To evaluate future changes in storm surge caused by global warming, dynamical downscaling was conducted using the Weather Research and Forecasting model for Typhoon Vera under present- and future-climate conditions and storm surge simulation using the Coupled Model of Surge, Wave, and Tide. The present-climate experiment entailed dynamical downscaling using data from the Japanese 55-year Reanalysis project as the initial and boundary conditions, and the future-climate experiments entailed downscaling considering future changes simulated through sea-surface temperature ensemble experiments using the Meteorological Research Institute Atmosphere General Circulation Model. The characteristics of the downscaled typhoon agreed well with the Best Track, and the future changes in the typhoon characteristics were as follows: intensification of the central pressure, delayed decline in the high-latitude area, and westward track migration. Present-climate storm surge simulation executed using these downscaling results after correcting for the track error agreed with the observed surge, but the storm surges under future-climate conditions were underestimated because of differences in the typhoon track and surface roughness. Storm surge simulations were conducted using an empirical typhoon model; the results suggest a storm surge of 26[math]cm (average of the ensemble) at Nagoya Port, which is located in the innermost region of Ise Bay.

  • Benefit–Cost Analysis on Coastal Structures Design for Climate
           Change Adaptation in Hong Kong
    • Authors: Ander Chow, Terence Leung, Francis Lee
      Abstract: Coastal Engineering Journal, Volume 59, Issue 02, June 2017.
      Some experts believe that Hong Kong will probably be subjected to more extreme weather conditions due to climate change. To better understand the potential implications of the effects of climate change on coastal structures in Hong Kong and to ascertain necessary revisions to the current design standards to minimize the risk of coastal flooding, the Civil Engineering and Development Department (CEDD) of the Hong Kong Special Administrative Region Government conducted a study to review the climate change situation in Hong Kong and its implications to coastal structures design. Projection method has been developed to project the two major climate change factors pertinent to design of coastal structures, i.e. the mean sea levels (MSLs) and extreme wind speeds, to different time windows of the 21st century based on IPCC AR5 scenarios. CEDD seriously considered investing in the future coastal structures by designing the new structures with climate change revisions as one of the adaptation measures against the climate change impact and undertook benefit–cost assessment to evaluate whether the adaptation measure is effective in coastal structures design. Three types of common coastal structures to cope with climate impact, i.e. sloping rock armor seawall, vertical blockwork seawall and piled-deck pier, were investigated. The cost–benefit analysis results demonstrated that the benefits of increased protection on new coastal structures to cope with climate change effects outweigh the additional costs incurred to construct and maintain these structures.

  • Estimation of Climate Change Impact on Storm Surges: Application to Korean
    • Authors: Sooyoul Kim, Jihee Oh, Kyung-Duck Suh, Hajime Mase
      Abstract: Coastal Engineering Journal, Volume 59, Issue 02, June 2017.
      The present study assesses the climate change impact on local storm surges along the coasts of the Korean Peninsula and Tottori Prefecture, Japan. A series of storm surge simulations are conducted on a physical process-based storm surge model using direct forcing from general circulation model output data in the two periods of 1979–2008 and 2075–2099. It is found that the typhoon intensity is enhanced and its number increases under the future climate condition in the area of the Korean Peninsula (32[math] to 40[math] N and 120[math] to 138[math] E). In addition, the typhoon approach course moves by 0.523[math] westward in the future climate. From a series of storm surge simulations, the statistical analysis showed that the climate change influences the storm surge height regionally and locally; it decreases on the west coast of the Korean Peninsula in the future, whereas it increases on the south coast of the Korean Peninsula and on the coast of Tottori Prefecture, Japan.

  • Predicting Breaking Wave Conditions Using Gene Expression Programming
    • Authors: Bryson Robertson, Bahram Gharabaghi, Hannah E. Power
      Abstract: Coastal Engineering Journal, Ahead of Print.
      The forces and loading resulting from shallow water breaking waves are one of the most important drivers in coastal engineering design and morphological change. The importance of accurately and precisely predicting breaking wave conditions cannot be overstated. Using a novel dataset of laboratory and field scale breaking wave conditions, this study assesses the performance of widely applied empirical relationships for breaking waves and uses newly available artificial neural networks and gene expression programming (GEP) numerical methods to develop an accurate and easily applied predictor of breaking conditions for coastal engineers and planners. A novel GEP model is developed and shown to: provide excellent predictive ability at all scales, greatly improve prediction compared with previous works at laboratory scale, and clearly identify the relevant importance of seafloor slope and the water depth to wavelength ratio.

  • Effect of Regulation of the Inlet Channel on Tides and Water Levels in
           Lake Hamana, Japan
    • Authors: Jon Hinwood, Shin-Ichi Aoki, Takumi Okabe
      Abstract: Coastal Engineering Journal, Ahead of Print.
      Hamanako is an economically and culturally important tidal lake on the Pacific coast of Honshu, Japan. Between 1954 and 1973, entrance works were constructed to regulate the channel to the lake. In a previous paper, the tidal records from Maisaka just inside the lake, prior to regulation, were analyzed to explain the responses of the lake to the ocean tide and other water level changes. The present paper compares water level responses with those following regulation of the entrance. The principal differences are that at Maisaka the tidal range increased up to 1965, following the first stages of regulation, but it has been constant since then. In the inner part of the lake, regulation has increased the tidal range but reduced its variability and has reduced the mean water level in the lake. The southern sand shoal divides the lake into two tidal basins, with Maisaka lying in the smaller outer basin. Studies of the inner basin have shown that its tidal range continues to increase. A hydrodynamic model has been used to show that this increase is primarily due to scouring of the inner channel through the southern shoal. The model has also shown that the constancy of the Maisaka tidal amplitude since 1965 is not a static equilibrium, but is a balance between the effects of the outer entrance channel scouring and increasing the Maisaka tide, offset by the inner channel scouring and reducing the Maisaka tide.

  • Reliability-Based Safety Analysis of a Seawall with Incomplete Information
           on Tsunamis
    • Authors: Kuo-Wei Liao, Hsi-Jui Hsiung
      Abstract: Coastal Engineering Journal, Ahead of Print.
      This study proposes a safety evaluation process for a prevention structure against tsunamis, in which the most updated guideline (i.e. FEMA P-646) is used as the deterministic analysis and a probabilistic approach is adopted to consider uncertainties involved. To overcome the incomplete data on Tsunamis, a Markov chain Monte Carlo (MCMC) simulation is developed to increase the quantity of historical data from Taiwan followed by the use of the least squares support vector machine (LS-SVM) to estimate the probability density function (PDF) of random variables. Based on the fragility analyses of the superstructure, substructure and entire system, if the wall thickness is below 4.45[math]m, the wall thickness is more likely to be the governing factor compared with the pile diameter. Conversely, the pile diameter would more likely be the dominating factor. When the pile size decreases from 75[math]cm to 65[math]cm, the threshold value will shift from 4.45[math]m to 3.85[math]m. In addition, when the wall thickness and height are greater, there is a greater likelihood of the failure probability being governed by the substructure. Based on historical records only, the probability of failure of the seawall is extremely low. Nevertheless, results shown here are in line with the engineering judgement and the computation procedure established in the present study can be used as a reference for performing safety analysis on tsunami structures with insufficient data.

  • An Equilibrium Transport Formula for Modeling Sedimentation of Dredged
    • Authors: L. M. Kaczmarek, Sz. Sawczyński, J. Biegowski
      Abstract: Coastal Engineering Journal, Ahead of Print.
      The proposed formula for modeling sedimentation is based on a concept of hydrodynamic equilibrium in sediment transport. Hydrodynamic equilibrium occurs when the sediment transport is in a form of grain jumps with the distance traveled [math] smaller than the one established in the numerical modeling. A first-order upwind scheme FDM is applied. It provides the solution to equations describing changes in bathymetry in time and space coupled with simultaneous changes of bed sediment distribution. A clear-cut division of sediment transport into those during wave crest and wave trough is proposed. The results of bathymetry modeling coincided satisfactorily with the laboratory data. Moreover, the longer the experiments run, the more the results of measurements are compliant with the calculations. A certain time is needed for sediment transport to reach the hydrodynamic equilibrium, especially when the suspended load is significant. It is reached after going through the initial stages of bed level changes coupled with simultaneous changes of grain size distribution. The application of the model to field conditions shows its ability to predict sedimentation of dredged channels. Furthermore, the calculations show a good agreement with measured bed grain size distributions of sediment samples taken from the sites within the navigational channel of Łeba Port in Poland.

  • The Future Prediction of the One-Dimensional Topography of the Estuary
           Delta of the Shirakawa River
    • Authors: Sota Nakajo, Kohei Nakanishi, Hikaru Ota
      Abstract: Coastal Engineering Journal, Ahead of Print.
      Predicting the long-term topographical change based on results of a time-slice experiment using a General Circulation Model (GCM) is difficult because actual change is a result of the continuum of events occurring in succession leading from the past to the future. We developed a one-dimensional topographical model of an estuary delta as the first step of assessing climate change effects. Three major effects, i.e. tidal flow, waves and sediment supply from the river, were included in this model. In order to estimate the sensitivity of these effects, simulations with virtual conditions were conducted. These simulations show equilibrium profiles that are close to the results of Roberts et al. 2000] “Predicting the profile of intertidal mudflats formed by cross-shore tidal currents,” Proc. Marine Sci. 3, 263–285.]. The simulation results were validated with observation data from the Shirakawa River delta. As a long-term prediction (about 37 years), the propagation of the rollover point was less than the actual data showed. The gradient of the subtidal zone was gentler than that observed. However, the short-term prediction (about 17 years) agrees with the observation data. These results show that old, unreliable, observation data used as a boundary condition significantly affects the reproducibility of the actual tidal flat profile. Finally, the effect of continuous Sea Level Rise (SLR) over 100 years from the present was investigated. As expected, the simulation results show a shift of the shoreline landward. The water depths in the intertidal and subtidal zones increase compared to a no-SLR condition. Therefore, the topset area grows as a consequence of SLR. Additionally, it was shown that future accumulation in the subtidal zone is reduced with SLR.

  • On the Role of Climate Change on Wind Waves Generated by Tropical Cyclones
           in the Gulf of Mexico
    • Authors: Christian M. Appendini, Adrián Pedrozo-Acuña, Rafael Meza-Padilla, Alec Torres-Freyermuth, Ruth Cerezo-Mota, José López-González, Pablo Ruiz-Salcines
      Abstract: Coastal Engineering Journal, Ahead of Print.
      To generate projections of wave climate associated to tropical cyclones is a challenge due to their short historical record of events, their low occurrence, and the poor wind field resolution in General Circulation Models. Hence, synthetic tropical cyclones provide an alternative to overcome such limitations, improving robust statistics under both present and future climates. We use synthetic events to characterize present and future wave climate associated with tropical cyclones in the Gulf of Mexico. The NCEP/NCAR atmospheric reanalysis and the Coupled Model Intercomparison Project Phase 5 models NOAA/GFDL CM3 and UK Met Office HADGEM2-ES, were used to derive present and future wave climate under RCPs 4.5 and 8.5 scenarios. The GFDL model shows less bias in the present climate with respect to NCEP/NCAR results. Furthermore, the numerical results suggest an increase in wave activity for the future climate in the Caribbean Sea and Northern Gulf of Mexico, whereas some areas are expected to decrease the wave energy, as the stretch of the Gulf of Mexico between Yucatan and Southern Texas. The results have practical implications on the design of offshore structures. The 100-year design wave based on the present climate might result in under/over design of structures, owing to the lifespan of a structure that is within the future wave climate period.

  • An Improved Prediction for Wave Runup on a Circular Cylinder
    • Authors: Deping Cao, Zhenhua Huang, Fang He, Wei Jian, Edmond Lo Yat-Man
      Abstract: Coastal Engineering Journal, Ahead of Print.
      Previous studies have applied various methods to analyze the wave runup on fixed columns, including linear and higher order diffraction theories and semi-empirical correlations. However, none of them seems to be adequate to accurately predict the wave runup over a full range of wave steepness and cylinder sizes when further compared with experimental data from the literature. The focus of this study is on a better semi-empirical formula for wave runup on a circular cylinder. We: (i) report on a set of experimental results obtained for a circular cylinder with various diameters in regular waves; (ii) evaluate the performance of existing theories or empirical equations using a full data set comprising new experimental results and results reported in the literature; and (iii) propose a new equation for predicting the wave runup on a fixed circular cylinder in regular waves. The proposed semi-empirical equation considers both the effects of wave scattering and wave nonlinearity and is able to estimate the runup of regular waves on a circular cylinder with significantly improved accuracy when tested with the full experimental data set.

  • The Influence of Climate Change on Coastal Erosion Vulnerability in
           Northeast Brazil
    • Authors: Karoline Angélica Martins, Pedro de Souza Pereira, Rodolfo Silva-Casarín, Antônio Vasconcelos Nogueira Neto
      Abstract: Coastal Engineering Journal, Ahead of Print.
      In this paper, an adapted methodology to evaluate coastal erosion vulnerability, which provides a basis for decision-making concerning risk management strategies, is described. The vulnerability evaluation was based on weighted indicators and assessed the vulnerability under different climate change scenarios. To generate the vulnerability index, dynamic processes, geo-indicators, and social and morphological parameters associated with modeled scenarios of sea level rise and predicted wave height changes were integrated. The study area included the sandy beaches in Pernambuco, NE Brazil, and was used to describe the practical application of this approach. Because the occupation of large sectors of the coastline was low, the vulnerability was concentrated in urbanized areas. The high-vulnerability sections of the coast were those with high population densities, high-rise buildings, induced coastal squeeze and hard engineering structures. The low-vulnerability beaches generally had low urbanization rates and well-conserved, resilient coastlines. Under future scenarios, the vulnerability of this coastal region will increase with sea level rise and wave height changes.

  • An Approximation to the Statistical Characteristics of Wind Waves in Front
           and from the Toe of the Structure to the Toe of the Crown of Nonovertopped
    • Authors: Montse Vílchez, María Clavero, Asunción Baquerizo, Miguel A. Losada
      Abstract: Coastal Engineering Journal, Ahead of Print.
      According to the main recommendations and technical criteria along the world, the design project of a breakwater must address the verification of the different failure modes that can affect the breakwater stability. This research focuses on the estimation of the statistical characteristics of the wind waves interacting with different breakwater types and their evolution from the toe of the structure to the toe of the crown. This knowledge is essential to calculate the reliability of the structure in its useful life. Partial standing wave patterns are likely to occur in front and along the section of the breakwater depending on their typology. Based on Rice’s theory of envelope amplitude, we present an approximate solution of the total wave height distribution in front of the breakwater. The experimental results in 2D confirmed that the incident, the reflected and the total wave height in front of the breakwater followed a Rayleigh distribution in which the parameter is the root-mean-square total wave height. Its value depends on the modulus and phase of the reflection coefficient. The probability density function of the total wave height evolves from a Rayleigh to a Weibull distribution, whose scale and shape parameters vary from the toe to the crown of the structure, and depend on the breakwater type, the relative grain diameter, and the relative water depth. The largest deviation from the Rayleigh distribution occurs at the toe of the crown. These findings are weakly dependent on the incident wave steepness, and are valid for narrow-banded incident wave trains, impinging perpendicularly on nonovertopped breakwaters with a steep frontface, which ensures the rapid evolution of the wave train. Then, each mode of failure that might occur in the breakwater section can be formally checked against the same incident wave height, but verified (calculated) with the actual wave height, locally transformed by the specific typology.

  • Projections of Future Beach Loss in Japan Due to Sea-Level Rise and
           Uncertainties in Projected Beach Loss
    • Authors: Keiko Udo, Yuriko Takeda
      Abstract: Coastal Engineering Journal, Ahead of Print.
      In this study, we projected the future beach loss in Japan’s 77 coastal zones due to sea-level rise (SLR) based on representative concentration pathway (RCP) scenarios and 21 models of the Coupled Model Intercomparison Project Phase 5 (CMIP5). The beach-loss curve for SLR in Japan was constructed, and uncertainties associated with SLR projections and sediment sizes were evaluated. Beach-loss rates in the future (2081–2100) were projected to be 62% for the ensemble mean RCP2.6 scenario, 71% for RCP4.5, 73% for RCP6.0, and 83% for RCP8.5, and the rates projected by the CMIP5 models for RCP4.5 ranged widely from 61% to 87%. The effect of the spatial distribution of SLR in each CMIP5 model on beach-loss rate in Japan is insignificant, while the effects of differences in the SLR values among RCP scenario and CMIP5 models are significant. The maximum uncertainties associated with sediment sizes (0.2–0.6[math]mm) against the same SLR were assessed to be 38%. Despite significant uncertainties in the projected beach loss, results in the near future (2046–2065) reveal that the beach-loss rates between 18% and 79% differed by 60% in the near future and between 28% and 96% differed by 70% in the future. For the worst case scenario in the near future, the projected beach width is less than 10[math]m in more than half of the 77 coastal zones, which would cause serious damage to coastal structures such as seawalls and revetments in beach areas. Thus, the development of effective measures to combat beach loss is critical for Japan’s coastal management.

  • Entrainment and Transport Dynamics of Shipping Containers in Extreme
           Hydrodynamic Conditions
    • Authors: Jacob Stolle, Ioan Nistor, Nils Goseberg, Takahito Mikami, Tomoya Shibayama
      Abstract: Coastal Engineering Journal, Ahead of Print.
      An experimental study was performed to examine multiple debris entrainment and transport in tsunami-like flow conditions. The study was performed in the Tsunami Wave Basin at Waseda University. The wave basin used a falling-head driven elongated solitary wave that broke at the edge of a horizontal apron to generate a tsunami-like surge. The debris, modeled as scaled-down (1:40 length scale) 20-foot standard shipping containers, was placed on the horizontal apron. The debris was tracked using a camera-based object tracking algorithm. The study examined the effect of the debris configuration, the number of debris, and orientation of debris on the entrainment and transport within the inundating surge. In examining the transport of multiple debris, the debris tended to be transported within the surge as an agglomeration. Using a previously derived model of debris the study determined experimentally derived coefficients to explain the difference in debris transport between various configurations.
