A comprehensive framework for optimising the effects of inverse logistics practices in SC sustainability
Authors: López Vargas Cristina
Published: June 2017

With growing sustainability concern in mind, firms seek to implement reverse logistic systems in their operations. However, if these practices were not properly implemented, they would be costly and even ineffective. In order to guide company efforts, the present study provide a comprehensive framework based on two dimensions. On one hand, it suits a reverse logistic management model stage-by-stage. On the other hand, the framework brings together concrete measures to optimize SC sustainability from three perspectives: operative, economical and environmental. The proposed framework thus allow to balance reverse logistic practices and SC sustainability. Furthermore, we validated it by analysing six real case in different industries. Findings highlight how reverse logistic activities may improve each SC sustainability dimension.

Authors: Mejia-Villa Andres , Alfaro-Tanco José Antonio
Published: June 2017

This study pretends to highlight the usefulness of developing action research (AR) projects as a way to develop a set of integrated studies based on a dual contribution: academic and managerial ones. The concept of AR Project goes one step ahead in terms of AR methodology as an extended case study. We describe an specific AR Project associated to a doctoral theses in the field of innovation intermediation. As main results, we have learned from this experience that (1) the relationship between researchers and practitioners must be collaborative and based on trust and commitment, (2) an AR Project is broader and more complex than a case study, (3) the diffusion of research results must be differentiated for practitioners and academics, and finally, (4) the AR Project is an open and collaborative innovation practice.
Modal properties and stability of bend–twist coupled wind turbine blades
Authors: Stäblein Alexander R. , Hansen Morten H. , Verelst David R.
Published: June 2017

Abstract. Coupling between bending and twist has a significant influence on the aeroelastic response of wind turbine blades. The coupling can arise from the blade geometry (e.g. sweep, prebending, or deflection under load) or from the anisotropic properties of the blade material. Bend–twist coupling can be utilized to reduce the fatigue loads of wind turbine blades. In this study the effects of material-based coupling on the aeroelastic modal properties and stability limits of the DTU 10 MW Reference Wind Turbine are investigated. The modal properties are determined by means of eigenvalue analysis around a steady-state equilibrium using the aero-servo-elastic tool HAWCStab2 which has been extended by a beam element that allows for fully coupled cross-sectional properties. Bend–twist coupling is introduced in the cross-sectional stiffness matrix by means of coupling coefficients that introduce twist for flapwise (flap–twist coupling) or edgewise (edge–twist coupling) bending. Edge–twist coupling can increase or decrease the damping of the edgewise mode relative to the reference blade, depending on the operational condition of the turbine. Edge–twist to feather coupling for edgewise deflection towards the leading edge reduces the inflow speed at which the blade becomes unstable. Flap–twist to feather coupling for flapwise deflections towards the suction side increase the frequency and reduce damping of the flapwise mode. Flap–twist to stall reduces frequency and increases damping. The reduction of blade root flapwise and tower bottom fore–aft moments due to variations in mean wind speed of a flap–twist to feather blade are confirmed by frequency response functions.
In-Vitro Antioxidant Capacity and Bioactive Compounds Preservation Post-Drying on Berrycacti (Myrtillocactus geometrizans)
Authors: Santiago-Mora Priscila Desiree , Cardador-Martinez Anaberta , Tellez-Perez Carmen , Montejano-Gaitan Jose Gerardo , Martin del Campo Sandra T.
Published: June 2017

Berrycactus is a cactus which does not require special agronomic attention, the berries are consumed locally and its commercialization is rather scarce because of the extremely short shelf-life. The significance of the application of any drying methods used to extend the shelf-life on the berrycacti is currently unknown. The aim of this work was to preserve berrycacti (Myrtillocactus geometrizans) and test the bioactive compounds and antioxidant capacity using two distinctive drying methods, freeze-drying (FD) and Instant Controlled Pressure Drop (DIC). Ripe berrycacti was chosen for the drying procedures because the antioxidant capacity and levels of soluble phenols and betalains were at their peak. Colour, phenols, non-extractable polyphenols, tannins, betalains, and antioxidant capacity were considered as factors to determine drying efficacy. Only colour parameters could discriminate between FD and DIC, concluding that both methods are suitable and efficient for preservation of antioxidant properties and retention of bioactive compounds. Both drying methods demonstrated higher in-vitro antioxidant capacity compared to the fresh fruit; highlighting the increase of non-extractable polyphenols and condensed tannins, and good retention of betalains and ascorbic acid after the drying treatments. This research points to use this sustainable crop to provide added value to berrycacti while considering this fruit as functional food due to the antioxidant capacity present even after being processed.

Making sense of ESOL policy: Tutor perspectives
Authors: Courtney Clare
Published: June 2017

This paper explores tutor perspectives on ESOL (English for Speakers of Other Languages) learners in the UK. Government policy towards ESOL is increasingly driven by an ideology in which citizenship is conflated with the acquisition of English language skills. Underpinning this way of thinking are concepts of Othering and deficiency. My research aimed to investigate how tutors “make sense” (Spours, Coffield, & Gregson, 2007; James & Biesta, 2007) of ESOL policy in the UK, how this informs tutors’ attitudes towards English language learners, and to understand the potential impact that such attitudes could have on learners. The study demonstrates that tutors are influenced in their attitudes towards their learners by the persistent external issues of funding and the contradictory discourse implicit in ESOL policy. Such attitudes can have a tangible effect on learners.
Formování inkluzivního prostředí na české škole jako priorita pedagogické antropologie

Published: June 2017

Každý žák by měl bez ohledu na svůj sociální původ, etnicitu, barvu pleti, náboženské vyznání, gender či zdravotní handicap zažívat ve škole pocit rovnosti. To je jeden z předpokladů rozvoje inkluzivního vzdělávání, na jehož formování se v současném českém školství podílí mj. multikulturní výchova. V naší studii reflektujeme roli pedagogů a jejich vliv na formování hodnot a postojů jejich žáků, ve vztahu k jinakosti, přičemž se opíráme jednak o poznatky pedagogické antropologie, která jako aplikační věda podporuje proinkluzivní přístup ve výchově a vzdělávání, a jednak o zjištění plynoucí z našeho výzkumného šetření mezi pedagogy základních a středních škol v České republice. Výsledky ukazují, že pedagogové odmítají odpovědnost za utváření názorů žáků, přitom je zřejmé, že se svými žáky stereotypy o těch tzv. jiných často sdílejí.

Proximal clustering between BK and CaV1.3 channels promotes functional coupling and BK channel activation at low voltage
Authors: Vivas Oscar , Moreno Claudia M , Santana Luis F , Hille Bertil
Published: June 2017

CaV-channel dependent activation of BK channels is critical for feedback control of both calcium influx and cell excitability. Here we addressed the functional and spatial interaction between BK and CaV1.3 channels, unique CaV1 channels that activate at low voltages. We found that when BK and CaV1.3 channels were co-expressed in the same cell, BK channels started activating near −50 mV, ~30 mV more negative than for activation of co-expressed BK and high-voltage activated CaV2.2 channels. In addition, single-molecule localization microscopy revealed striking clusters of CaV1.3 channels surrounding clusters of BK channels and forming a multi-channel complex both in a heterologous system and in rat hippocampal and sympathetic neurons. We propose that this spatial arrangement allows tight tracking between local BK channel activation and the gating of CaV1.3 channels at quite negative membrane potentials, facilitating the regulation of neuronal excitability at voltages close to the threshold to fire action potentials.

Introduction: Pseudomonas are ubiquitous bacteria widely present in nature. However, they have emerged as an opportunistic pathogen for humans. This bacterium is accountable for many localized and disseminated diseases, especially wounds in burn patients, respiratory infections, septicemia and bacteremia. Among all Pseudomonas species, P. aeruginosa is one of the important and most virulent species in hospital settings, while other pathogenic species include stutzeri, putida and fluorescence. The aim of this study was to assess pattern of antibiotic resistance in these bacteria isolated from a University teaching and treatment center. This cross-sectional study was conducted on 99 Pseudomonas strains (68 strains P. aeruginosa and 31 other Pseudomonas species) isolated from various clinical specimens. Antimicrobial drug susceptibility test was performed using the disc agar diffusion method according to CLSI recommendations. In this study, among various clinical specimens sent to microbiology laboratory, wound (59.59%) was found as a major source of Pseudomonas spp. Among various wards, Pseudomonas spp. was isolated more from patients admitted to burns ward (48.48%). Antibiotic susceptibility assay results revealed non susceptibility pattern towards most of the antibiotics; however, among all antibiotics tested, most common resistance was observed towards ceftazidime (76.76%). The results of this study shows the presence of Pseudomonas infection in the hospital setting and their developed resistance towards many conventional antibiotics, which is a concern at this treatment center. Thus, there exist a need for evaluation of careful and accurate measurement of resistance and assessment of exact drug administration policies. Therefore, to control the infection and prevent from increased prevalence of resistant strains appropriate resolution should be followed.
Who are the important predators of sea turtle nests at Wreck Rock beach?
Authors: Lei Juan , Booth David T.
Published: June 2017

Excessive sea turtle nest predation is a problem for conservation management of sea turtle populations. This study assessed predation on nests of the endangered loggerhead sea turtle (Caretta caretta) at Wreck Rock beach adjacent to Deepwater National Park in Southeast Queensland, Australia after a control program for feral foxes was instigated. The presence of predators on the nesting dune was evaluated by tracking plots (2 × 1 m) every 100 m along the dune front. There were 21 (2014–2015) and 41 (2015–2016) plots established along the dune, and these were monitored for predator tracks daily over three consecutive months in both nesting seasons. Predator activities at nests were also recorded by the presence of tracks on top of nests until hatchlings emerged. In addition, camera traps were set to record the predator activity around selected nests. The tracks of the fox (Vulpes vulpes) and goanna (Varanus spp) were found on tracking plots. Tracking plots, nest tracks and camera traps indicated goanna abundance varied strongly between years. Goannas were widely distributed along the beach and had a Passive Activity Index (PAI) (0.31 in 2014–2015 and 0.16 in 2015–2016) approximately seven times higher than that of foxes (PAI 0.04 in 2014–2015 and 0.02 in 2015–2016). Five hundred and twenty goanna nest visitation events were recorded by tracks but no fox tracks were found at turtle nests. Camera trap data indicated that yellow-spotted goannas (Varanus panoptes) appeared at loggerhead turtle nests more frequently than lace monitors (V. varius) did, and further that lace monitors only predated nests previously opened by yellow-spotted goannas. No foxes were recorded at nests with camera traps. This study suggests that large male yellow-spotted goannas are the major predator of sea turtle nests at the Wreck Rock beach nesting aggregation and that goanna activity varies between years.

THE GEOLOGICAL ASPECTS OF COASTAL ENGINEERING
Authors: Handin John W.
Published: June 2017

A natural beach system is in equilibrium when there is a balance between sand supply and erosion such that the volumes of material entering and leaving the system are just equal. If the erosion rate exceeds the supply rate, a beach retrogrades; if the erosion rate is less than the supply rate, a beach progrades. Unfortunately, coastal engineering works, which are meant to improve the shore for commerce or recreation, often upset this delicate balance with very deleterious results: great accretions of sand and high dredging costs, accelerated beach erosion and much property damage. It is the task of the geologist to determine the secular equilibrium conditions of a beach system and to supply the coastal engineer with the information he needs to control the natural forces acting on the shore in such a way that this equilibrium is maintained. In order to accomplish this task, the geologist needs to make a thorough study of the source, transportation, and deposition of beach sediment. He must determine the stable position of the shore line and the profile of equilibrium of the beaches through detailed physiographic investigations. The geological report can and should close with the prediction of just what will happen to a natural beach system if man introduces a disturbing element.
CONTRIBUTION OF HYDRAULIC MODELS TO COASTAL SEDIMENTATION STUDIES
Authors: Simmons Henry B.
Published: June 2017

The use of hydraulic models in coastal sedimentation studies dates back more than 60 years. To the best of the writer's knowledge, the first such model was of the tidal portion of the Mersey River in England, and was constructed and operated by Professor Osborne Reynolds in the year 1887. Data obtained from the model tests by Professor Reynolds were used in the location and design of navigation channels from the sea to the port of Liverpool. Since the time of Professor Reynolds, numerous models have been used in this and other countries for studies of coastal sedimentation problems. The first such study made by the waterways Experiment Station was of Winyah Bay, South Carolina in 1933, and was followed by studies of Ballona Creek outlet near Venice, California; Galveston Harbor, Texas; Absecon Inlet at Atlantic City, New Jersey; the Umpqua River entrance in Oregon; Lynnhaven Inlet near Norfolk, Virginia; and many others. This paper covers in a general way the types of coastal sedimentation problems subject to model analysis, the types of models used, model instruments and appurtenances, field data requirements, adjustment and verification of models, testing of proposed improvement plans, the analysis of test results, and the limitations of models.
LOCATION OF HARBORS
Authors: Peel Kenneth P.
Published: June 2017

The location of harbors is dependent on many factors, which vary widely in different parts of the country. For example, along the Atlantic coast are many natural waterways. The improvement of these waterways, especially for small craft, is comparatively inexpensive and harbors are constructed at frequent intervals. However, along the coast of southern California, natural facilities are almost nonexistent. Consequently, improvements are farther apart and correspondingly larger. The cost per boat accommodated remains about the same. In general, this discussion is based on conditions along the coast of California, particularly southern California. The purpose of this paper is to show how the costs, functions, types, sizes, and physical features of harbors and the effect of harbors on adjacent shore lines and underground basins are related to the selection of a proposed harbor site. Typical examples, with brief discussions of the principal factors involved in the selection of harbor Sites, are given later in this paper.
DESIGN AND CONSTRUCTION OF GROINS
Authors: Horton Donald F.
Published: June 2017

Groins are frequently used for shore protection and improvement. Not infrequently the owner of shore property who has had groins built to protect or improve his property is disappointed with the results. More often than not this unhappy situation must be attributed to the fact that too much was expected by the owner. The owner in such a case is not properly to be criticized, because a great deal remains to be learned about groins; their effects, their proper design and construction. In the present state of the art of shore protection and improvement it is not possible to design and build groins without facing numerous uncertainties, particularly in the area of advance determination of the results which will be accomplished. This condition is faced frankly at the very beginning of this paper and should be kept in mind throughout the consideration of the subject of groin design and construction. This paper presents a digest of what is considered by the writer to be the best current practice. No pretense is made for the development of original ideas on the subject. The writer is indebted to many engineers who have contributed accounts of their experiences to the literature, and to the members of the Beach Erosion Board and its staff, especially Dr. Martin A. Mason.
CASE HISTORY OF SHORE PROTECTION AT PRESQUE ISLE PENINSULA, PA.
Authors: Lee Charles E.
Published: June 2017

The beach protection aspects rather than the importance to navigation of Presque Isle Peninsula is stressed in this paper, The history of the locality is so extensive that only that which bears on beach protection and the portion deemed pertinent to provide background to the early importance of the site will be related. The three main reasons for protecting Presque Isle Peninsula are as follows: for protection of the natural harbor at Erie, Pennsylvania; for the preservation of the beaches which provide Pennsylvania's only public lakeshore recreational area on Lake Erie; and to prevent destruction of the only land access to the facilities on the peninsula. It is reported that in 1947 over 1,500,000 people visited the 3,200 acre Presque Isle State Park. There are also located on the peninsula installations of the Erie Water Works, the United States Coast Guard and the Pennsylvania State Department of Fisheries.
3D PHYSICAL MODELING OF TSUNAMIS GENERATED BY SUBMERGED LANDSLIDES AT A CONICAL ISLAND: THE ROLE OF INITIAL ACCELERATION

Published: June 2017

This paper presents a new set of 3D experiments aimed to gain insight on the role of the initial acceleration upon the generation process of tsunamis by submerged landslides that may occur at the flanks of conical islands. The
experiments have been carried out in a large wave tank by varying the initial acceleration of the landslide model. A novel system, relying on the use of a computer controlled stepped motor, has been employed to control the motion of the landslide model. The experiments have been carried out in a parametric way by changing the initial acceleration of the landslide, aiming to reproduce dierent triggering mechanisms. Preliminary experimental findings confirmed the crucial role of the initial acceleration of the submerged landslide in generating tsunamis.
ANALYSIS OF NEARSHORE LOCAL EFFECTS ON TIDAL BEHAVIOUR AT IMAM KHOMEINI PORT AND MUSA BAY
Authors: Rezaei Yeknami Saeed , Soltanpour Mohsen , Ranji Zahra
Published: June 2017

Tidal waves have very different dynamics in shallow waters, in comparison to deep sea waters. When a tidal wave approaches to nearshore areas, it might be affected by different factors such as resonance, shoaling in landward direction, funneling due to the decrease of the width, damping due to bottom friction, and partial reflection at abrupt changes of the cross-sections of estuary. Coriolis force can also deflect the tidal waves in large areas, which may lead to the changes of tidal ranges near the coasts. The high increase of tidal range at Musa Bay, located at the north-western part of the Persian Gulf, is studied in this paper. Numerical modeling confirms the occurrence of the resonance for a period of about 8-9 hr., where the amplification factor is gradually decreased with further increase of the wave period. Results implied that resonance, funneling and shoaling are the three most effective parameters which amplify the tide in this area.
IN MEMORIAM: Maarten Dingemans
Authors: Liu Philip L.-F. , Mynett Arthur
Published: June 2017

Maarten Dingemans passed away due to heart failure in the hospital on January 12, 2017. Maarten was born 15 Aug 1943 in Haarlem, the Netherlands, where he attended high-school at the Lorentz Lyceum. He started his studies at Delft University of Technology in 1962; initially in Mechanical Engineering, and later in the Faculty of Mathematics.

After receiving his Ir degree in Mathematics from Delft University of Technology in September 1970, Maarten started working at Delft Hydraulics in 1970 as a Mathematical Engineer until his retirement in 2007. During his career at Delft Hydraulics, Maarten involved in numerous coastal research grants and industrial engineering projects. One of the well-known laboratory benchmark experiments have been nick-named as â€œDingemansâ€™ barâ€ experiment.

On November 21, 1994 Maarten received his PhD degree from Delft University of Technology. Prof. dr. ir. A.J. Hermans was his promoter. The World Scientific Publishing Co later published his doctoral thesis, entitled â€œWater wave propagation over uneven bottomsâ€, as a two-part book with the same title in 1997. Many students, researchers and engineers in the coastal engineering community have studied and referenced this book.

In 1985 he continued working at Delft Hydraulics at De Voorst and he moved his family to Emmeloord. On September 1st 2007, at age of 64, he officially retired from Delft Hydraulics. However, he kept himself busy attending conferences and workshops all over the world, and writing and reviewing various articles. At the time of his passing he was still working on an article together with Dr. ir. Gert Klopman.

Throughout his entire life Maarten has faced continued health challenges. His courage to cope with ill health has always been inspiration to many of his friends and colleagues. Maarten enjoyed cycling, especially cross-country bicycle journeys during his healthy days. He once wrote: â€œLong-distance cycling to and from work stimulates the realization that things do not run as smoothly as one wishes they should.â€

Maartenâ€™s biggest loss in life was the passing of his wife Marja (also a mathematician and a colleague at Delft Hydraulics) 21 years ago now. Maarten dedicated his book to the memory of his beloved wife Marja.
MODEL VERSUS NATURE: HYDRODYNAMICS IN MANGROVE PNEUMATOPHORES
Authors: Horstman Erik M , Bryan Karin R , Mullarney Julia C , Pilditch Conrad A
Published: June 2017

Water flows through submerged and emergent vegetation control the transport and deposition of sediment in coastal wetlands. Many past studies into the hydrodynamics of vegetation fields have used idealized vegetation mimics, mostly rigid dowels of uniform height. In this study, a canopy of real mangrove pneumatophores was reconstructed in a flume to quantify flow and turbulence within and above this canopy. At a constant flow forcing, an increase in pneumatophore density, from 71 m-2 to 268 m-2, was found to cause a reduction of the within-canopy flow velocities, whereas the over-canopy flows increased. Within-canopy velocities reduced to 46% and 27% of the free-stream velocities for the lowest and highest pneumatophore densities, respectively, resulting in stronger vertical shear and hence greater turbulence production around the top of the denser pneumatophore canopies. The maximum Reynolds stress was observed at 1.5 times the average pneumatophore height, in contrast to uniform-height canopies, in which the maximum occurs at approximately the height of the vegetation. The ratios of the within-canopy velocity to the free-stream velocity for the pneumatophores were found to be similar to previous observations with uniform-height vegetation mimics for the same vegetation densities. However, maxima of the scaled friction velocity were two times smaller over the real pneumatophore canopies than for idealized dowel canopies, due to the reduced velocity gradients over the variable-height pneumatophores compared to uniform-height dowels. These findings imply that results from previous studies with idealized and uniform vegetation mimics may have limited application when considering sediment transport and deposition in real vegetation, as the observed turbulence characteristics in non-uniform canopies deviate significantly from those in dowel canopies.

Published: June 2017

Breaching of sandy coast was commonly observed on Yamamoto Coast, southern Miyagi Prefecture during the 2011 tsunami. That made the shoreline having concave shape after the tsunami. Concave shoreline is bounded by two headlands. The recovery of concave shoreline is discussed through the analysis of satellite images. The relationship between dimensionless elapsed time with dimensionless recovery of shoreline at the central line of concave portion, and dimensionless of area of backfilling in the concave portion are studied based on analytical solutions of the one-line model. For those two relationships, results obtained for case with rigid boundaries is asymptotic when the ratio between length of the bounded coast and width of concave portion is getting larger. Good agreement between measured data and theoretical results can be obtained.
NUMERICAL SIMULATION OF CROSS-SHORE PROFILE EVOLUTION USING OPENFOAM
Authors: Karagiannis Nikolaos , Karambas Theofanis , Koutitas Christopher
Published: June 2017

In the present work, an innovative numerical approach was developed coupling two models in order to simulate the wave propagation over a sloping beach and the sediment transport in surf and swash zones. The first model, synthesized on the basis of OpenFOAM (version 2.4.0) is used to describe the hydrodynamic characteristics of the flow and the wave propagation while the second one is applied for the sediment transport and erosion/deposition prediction using the results of the first model. The method above constitutes an iterative procedure which is tested hereby and seems to yield satisfactory numerical results in comparison with experimental data (Dette 1998).
A STUDY ON UPLIFT PRESSURES OF TSUNAMI ACTING ON CEILINGS OF WATER CHANNELS
Authors: Takabatake Tomoyuki , Oda Yukinobu , Ito Kazunori , Honda Takahide
Published: June 2017

When tsunami enters a water channel of an industrial facility, the water surface inside the channel rises and uplift pressures act on the ceiling if it is reached by the water surface. In this study, magnitudes and characteristics of this uplift pressure are investigated both experimentally and numerically. The results show that (1) the uplift pressure comprises an initial impulsive pressure and a following more slowly varying pressure; (2) trapped air reduces the impulsive pressure, and thus attaching a vertical barrier to the ceiling could act as a countermeasure; and (3) the impulsive pressure can be evaluated approximately with conventional predictive methods and by appropriate numerical simulations.

Published: June 2017

Overtopping discharges over a composite seawall model has been studied experimentally. Effect of crest elevations on the overtopping discharges was studied based on the new data set of 132 tests. Test data is compared to the existing formulas given by EurOtop Manual (2007) and EurOtop II Manual (2016). Results showed that both EurOtop Manual (2007) and EurOtop II (2016) formulas for composite seawalls are applicable to our test setup with a roughness coefficient of 0.55 which corresponds a rubble mound composite structure with two layers and an impermeable core.
Vertical wall caused the composite structure act as an impermeable structure. Height of the storm wall was raised 2, 4, 6, 8, and 10 cm successively during the tests. Results showed that a reduction rate clearly depends on the wave steepness.

This paper presents the feasibility study for a green touristic infrastructure by the installation of a WEC system in the port of Giardini Naxos, in the Mediterranean Sea. The area is characterized by a low amount of annual wave energy. The WEC system chosen is the OWC and its geometry has been tested by means of a small scale physical model. The surface elevation and the pressure on the structure have been recorder in such tests in order to evaluate, respectively, loadings and reflection at the front wall. The eigenperiod of the water column inside the device is also obtained. Finally, the economic return is estimated.

Munna Point is a premiere recreational beach in the Noosa River which has been maintained by regular nourishment for over 20 years. As longevity of each nourishment was less than 6 months, the long-term costs were high and efforts were eventually suspended resulting in loss of the beach. In an effort to reinstate the amenity and provide a more stable beach, a groyne field accompanied by nourishment was proposed. To provide a low-impact, low-risk and low-cost solution, the groynes were designed with a low crest using sand-filled geotextile containers. To achieve the design, containers and scour mattresses were filled in-situ using a dredge, which was an innovative application of a methodology typically adopted for much larger containers. The first 3 groynes have successfully been installed as part of the first stage and 12 months of monitoring subsequently undertaken. The groynes have clearly been effective at extending the longevity of the nourishment and the wider intertidal profile has remained very stable. The beach is now successfully enhancing the amenity of the community and experiencing a high level of usage.

A case-study pertaining to a number of existing breakwaters located on northern coastlines of the Gulf of Oman, directly facing the Makran Subduction Zone (MSZ) sets the context in order to elucidate the adopted methodologies for both Probabilistic Tsunamis Hazard Analysis (PTHA) as well as investigating breakwater stability in the event of a major tsunami. MSZ stretches from west to east for over 900 (km), affecting the coastlines of Iran, Pakistan, India, Oman and UAE as a potential source of tsunami hazard. According to historical data, the last reported MSZ generated tsunami which was triggered by the 1945CE earthquake of 8.1 (Mw) magnitude caused human fatality figures of up to almost 4,000, in addition to major structural devastation in its wake. Of particular interest, is the fate of existing breakwaters along the northern shorelines of the Gulf of Oman whose design criteria did not initially incorporate tsunami-related considerations, providing impetus for the modeling, design & analysis efforts presented in this article to serve the two-fold objective of assessing the need for strengthening existing structures, which are virtually all of the rubble-mound type, as well as deriving suitable design criteria for new breakwaters in the MSZ related tsunami affected region of Iran, earmarked for significant new developments.
TOE STABILITY IN VERY SHALLOW WATER COMBINED WITH STEEP SEA BOTTOM

It is common to construct a rock toe berm of three to four rocks wide when concrete armor units are placed in the armor layer. This toe berm is a relevant element, especially in very shallow waters combined with steep sea bottoms, where waves directly attack the toe berm and the lowest part of the armor. Several formulas are available to estimate the damage to rock toe berms. In this paper, these formulas are compared for different design conditions within their range of application. Most of these formulas use the damage parameter Nod. However, there are often situations in which wider toe berms are required for a safe design, and the damage parameter Nod is not recommended. A methodology is thus proposed to design wider toe berms based on the damage to the nominal toe berm of three rocks wide (Nod*), considered as the most shoreward part of the toe berm which effectively supports the armor layer.

The spatial and temporal variation of wave spectrum under typhoon SANBA, which was the 16th typhoon originating in the northwestern Pacific Ocean in 2012, was examined. The typhoon SANBA passed through the middle of Korean peninsula whereas most of typhoons passed the Straits of Korea (eastern side of Korean peninsula). This unique path of typhoon SANBA provided interesting features of wave conditions. It was believed that wave heights were larger in the right side of the typhoon path because typhoons translation speed and rotational wind field were in the same direction (i.e., dangerous semicircle). However, observational evidence of wave spectrum under typhoon was still rare because of the difficulty in measurement. In this study, wave spectrum analysis under extreme storm condition of typhoon SANBA is given for the left and right sides of the path, including the information of significant wave height, peak period, and dominant wave direction. Wave measurements were obtained by directional wave rider buoys installed at Yeosu and Namhyeongjedo in Korea. Yeosu and Namhyeongjedo are located in each of the left and right of the path of the typhoon SANBA. The measurements provided distinguished wave conditions in each side of navigable semicircle and dangerous semicircle of the typhoon. Therefore it is possible to observe the spatial differences of the wave spectrum across the path of the typhoon, as well as temporal changes of wave spectrum as the typhoon evolves.
UPDATE OF THE EUROTOP NEURAL NETWORK TOOL: IMPROVED PREDICTION OF WAVE OVERTOPPING

Published: June 2017

The goal of this work is to present a synthesis of the improvements and updates developed to deliver the final version of the ANN tool adopted by the second edition of the wave overtopping manual, EurOtop, released on the internet in 2016. This tool consists of three identical but independent ANNs able to predict the main parameters representative of the wave-structure interaction processes, i.e. the mean wave overtopping discharge, the wave transmission and the wave reflection coefficients. The contribution focuses on the modifications of the ANN architecture carried out since the last ICCE conference to achieve an optimized representation of the wave overtopping, especially in case of low and extreme values of the overtopping discharge. The consistency of the ANN predictions is assessed through an artificial dataset including geometrical and climate input parameters that are varied with continuity, while the robustness of the tool is checked by applying the ANN to selected geometries excluded from the training database.
NUMERICAL SIMULATION FOR TSUNAMI-HEIGHT REDUCTION USING A VERY LARGE FLOATING STRUCTURE

Published: June 2017

The tsunami-height reduction using a very large floating structure, i.e., VLFS, is discussed, with the water waves, interacting with a floating thin-plate, simulated numerically. The final tsunami-height reduction rate increases, as VLFS length, VLFS flexural rigidity, or the wave height of an incident tsunami, is increased. If two VLFSs are utilized, the final tsunami-height reduction rate, also depends on the distance between the VLFSs. In two-dimensional tsunami propagation, another wave propagates to the outside, along the crest line of the main wave, leading to an additional tsunami-height reduction.
THE DEVELOPMENT OF A SAND BEACH BY DEEP-WATER WAVES
Authors: Flinsch Harold
Published: June 2017

In a previous paper**, it was shown that the mechanism of the trochoidal waves can be used to determine the equilibrium slope of a sand beach under any wave conditions. As a start it was assumed that the beach material was of uniform grain size, and that the waves approached the beach directly with all motion in planes at right angles to the shore line.

In the present paper, the application of the theory is shown in the development of various sand and gravel beaches. The equilibrium theory is studied in the light of the fact that there is usually considerable transportation of material along the shore. In particular, attention is called to the characteristics of beaches with rounded or pointed contours, of beaches whose ends are closed off by rocks or cliffs, or whose ends are open and extend into deep water without barriers of any kind.

A method of study and analysis is demonstrated which can be applied to all beaches. Finally, it is shown that an accurate forecast of the natural development of a beach can be made on the basis of the equilibrium slope equation, as well as a forecast of the effect of any structure placed in a naturally developing beach.
MAINTENANCE OF A NAVIGABLE CHANNEL THROUGH A BREAKTHROUGH AREA

Published: June 2017

The engineering problem described is one which is encountered on a portion along the Northeastern coastline where tidal currents and shifting sands are predominant features. Due to the extreme local variability of such phenomena, generalizations and similar precedents from which a solution might be adopted are seldom available. It is therefore necessary to attempt to reduce such problems to elements which can be treated by fundamental concepts. With this viewpoint, the proposed solution has been developed by applying elementary principles of energy dissipation to the local situation of a natural water passage, in which flow due to a tidal differential is essentially in one direction.
GRAPHICAL RECORDING OF WAVE PROFILES IN THE LABORATORY; HARMONIC ANALYSIS
Authors: Santon L.
Published: June 2017

We have developed a laboratory wave recorder of great simplicity which plots a wave profile to a scale which can be either 1 or 3 for the amplitude and which varies between 0,5 and 1 for the horizontal distances.

The apparatus, the principle of which we have already described at a time when we had not proved all its possibilities, has shown itself to be extremely sensitive for the study of fine phenomena.

We have used chronophotographic methods with aluminum powder to record wave motion. In this method, it is necessary to photograph fine selected and prepared particles which sink slowly but which are nevertheless large enough to reflect light through about half a meter of water in the wave flume.
SEA-DEFENCE WORKS OF THE ATLANTIC COAST BETWEEN THE LOIRE AND GIRONDE
Authors: Blondeau F. , Baste A.
Published: June 2017

Between the Loire and the Gironde, the Atlantic Ocean runs along a succession of zones, the level of which is lower than that of the Spring tides. The main ones are:

In the North, the marsh of Vendee, between the Loire and the Bocage (woody district): 50,000 hectares.

In the Center, the marsh of Poitou, between the Bocage and Aunis; 80,000 hectares.

In the South, the marsh of Saintonge, between Aunis and Saintonge: 50,000 hectares.

Natural defences (sand-hills, shingle beaches) exist in some places. But more often than not, the protection is assured by artificial defences. Seaside resorts (Chetelaillon, Royan) are protected by other works. Ahead of the coast line lie large islands (Noirmoutier, Re, Oleron) which include lowlands even more threatened than those on the continent. Therefore,this coast offers a great number of interesting works for the specialized engineer.
