Using oceanographer Rachel Carson's study The Edge of the Sea (1955) to contextualise tidal spaces, this chapter discusses how constantly shifting and eroding coastlines act as a site for writing, re-writing and performing acts of cultural and personal memory. It also considers the ecological impact of human activity on tidal spaces and their more-than-human inhabitants.

14-18 NOW's Pages of the Sea, directed by Danny Boyle, invited communities around the United Kingdom to meet on their local beach to commemorate those who were lost in World War I by marking portraits in the tidal sands. Choreographer Chloë Smith's Tidal, performed in Berwick-upon-Tweed in 2015, was commissioned as a commemorative work but became an act of personal memorialising when Smith's brother drowned prior to the event. Performance company Curious's Out of Water (2012–2014), invites participants on a dawn-walk to the shoreline exploring memory, time, genealogy and water through song and movement. My own collaborative site-responsive work, Tide Times (2018), created with electroacoustic composer Tim Cooper for the tidal island of Cramond, explores the multiple identities of place over time. Tide Times encouraged audiences to create their own tidal poems and artworks through a series of invitations in treasure chests hidden around the island.

In explicating these aforementioned artworks, which explore ideas of remembrance using tidal spaces, this chapter will also acknowledge the forgetting that is implicit in performing these actions. What can the legacy of commemorations traced in such a transient and precarious space as a tidal zone be? This chapter argues that while shorelines provide sites for large and small scale acts of public remembering, they are simultaneously acts of forgetting as the twice daily tides cause inevitable erasure.

The paper aims to propose a new mathematical model for allocation and scheduling of vessels at multiple marine container terminals of the same port, considering the access channel depth variations by time of day.

This paper proposes a new mathematical model for allocation and scheduling of vessels at multiple marine container terminals of the same port, considering the access channel depth variations by time of day. The access channel serves as a gate for vessels entering or leaving the port. During low-depth tidal periods the vessels with deep drafts have to wait until the depth of the access channel reaches the required depth.

A number of numerical experiments are performed using the operational data collected from Port of Bandar Abbas (Iran). Results demonstrate that the suggested methodology is able to improve the existing port operations and significantly decrease delayed vessel departures.

The contribution of this study to the state of the art is a novel mathematical model for allocation and scheduling of vessels at multiple terminals of the same port, taking into consideration channel depth variations by time of day. To the best of the authors’ knowledge, this is the first continuous berth scheduling linear model that addresses the tidal effects on berth scheduling (both in terms of vessel arrival and departure at/from the berth) at multiple marine container terminals.

A mathematical model and numerical method for water flow and solute transport in a tidal river network is presented. The tidal river network is defined as a system of open channels or rivers with junctions and cross sections. As an example, the Pearl River in China is represented by a network of 104 channels, 62 nodes, and a total of 330 cross sections with 11 boundary sections for one of the applications. The simulations are performed with a supercomputer for seven scenarios of water flow and/or solute transport in the Pearl River, China, with different hydrological and weather conditions. Comparisons with available data are shown. The intention of this study is to summarize previous works and to provide a useful tool for water environmental management in a tidal river network, particularly for the Pearl River, China.

Today’s graduate education should provide students with technical specialization and professional skills to holistically prepare them as genuine leaders, ready to address today’s complex and ethical dilemmas in the workplace. Inclusion of professional development complements their technical specialty by providing opportunities to develop successful, self-aware, authentic leadership within their fields. One way to develop these skills is through an interdisciplinary, online leadership development course. This study examines the effectiveness of an online leadership course in building authentic leadership skills over five academic semesters. Scores on the authentic leadership measure show statistical significance between the pre- and post-tests, with positive effect sizes in transparency and self-awareness. Results suggest that this online course, focused on personal and professional development, improves students’ understanding of themselves and the world around them and capacity to gain the trust of their followers.

The purpose of this paper is to research electrochemical testing technology as applied to in field corrosion evaluation of metallic materials and to study the corrosion behaviors of the materials exposed in different marine regions.

The electrode systems for in field electrochemical evaluation of metallic samples are designed and applied to monitor two types of carbon steel samples exposed both in the submerged zone and the tidal zone at a marine corrosion test station. Corrosion potential monitoring, potentiostatic square wave, electrochemical impedance spectroscopy, and electrochemical noise methods are used in the test.

It is confirmed that the electrode systems could be used for electrochemical measurement of metallic samples during exposure in the submerged zone and the tidal zone of a marine corrosion test station for long‐term test durations. The electrochemical measuring results reflect the changes and differences of the samples' corrosion behavior during exposure in different regions and they respond directly to the influence of marine environmental factors on the corrosion behaviors, especially the influence of temperature.

In this paper, lots of consecutive and dynamic corrosion information is obtained from field exposures. The findings provide a foundation upon which to investigate and forecast the corrosion behaviors of materials in marine environments.

The purpose of this paper is to highlight the use of small river ferries as an under-researched but novel mode of travel which enhances and brings new dimensions to tourist experiences of travelling landscapes.

The study used a mixed methods approach including participant observation, a survey and interviews with ferry users and staff at one river crossing in South West England.

The ferry attracts tourists as a different and practical mode of transport. The river crossing provides an experience of being on water, and the material structure of the ferry significantly shapes on-board interactions whilst providing new perspectives of place.

This article draws on data collected for a study of ferry crossings conducted at three sites in Devon and Cornwall, England, using multiple methods. The material presented in this article focuses on one site and draws on four interviews, twelve reflection cards and observations.

The research highlighted the extent to which the ferry is dependent on tourist use. At the same time, it reveals the extent to which the crossing enriches the tourist experience and celebrates a ferry’s contribution to local place-making.

The majority of research on ferry crossings focuses on commuter experiences, marine crossings and larger passenger vessels. This article makes an original contribution to literature on ferries, as it offers a perspective on tourist experiences of river ferry crossings, reveals how the ferry structure influences interrelations on-board and provides distinctive insights into place through a focus on movement across water.

This study aims to simulate Hunter turbine in Computer Forensic Examiner (CFX) environment dynamically. For this purpose, the turbine is designed in desired dimensions and simulated in ANSYS software under a specific fluid flow rate. The obtained values were then compared with previous studies for different values of angles (θ and α). The amount of validation error were obtained.

In this research, at first, the study of fluid flow and then the examination of that in the tidal turbine and identifying the turbines used for tidal energy extraction are performed. For this purpose, the equations governing flow and turbine are thoroughly investigated, and the computational fluid dynamic simulation is done after numerical modeling of Hunter turbine in a CFX environment.

The failure results showed; 11.25% for the blades to fully open, 2.5% for blades to start, and 2.2% for blades to close completely. Also, results obtained from three flow coefficients, 0.36, 0.44 and 0.46, are validated by experimental data that were in high-grade agreement, and the failure value coefficients of (0.44 and 0.46) equal (0.013 and 0.014), respectively.

In this research, at first, the geometry of the Hunter turbine is discussed. Then, the model of the turbine is designed with SolidWorks software. An essential feature of SolidWorks software, which was sorely needed in this project, is the possibility of mechanical clamping of the blades. The validation is performed by comparing the results with previous studies to show the simulation accuracy. This research’s overall objective is the dynamical simulation of Hunter turbine with the CFX. The turbine was then designed to desired dimensions and simulated in the ANSYS software at a specified fluid flow rate and verified, which had not been done so far.

The purpose of this paper is to describe and critically review the new tenure arrangements that have been established to recognise Māori relationship with land (Te Urewera) and river (Whanganui River), to ascribe them their own legal personality.

The paper describes the development of the legal arrangements in Aotearoa, New Zealand, for Treaty settlements with Māori, and documents the various forms of rights and divisions of space that are changing the face of property institutions.

The paper finds that the acknowledgement of land and nature as having their own legal status and, therefore, owned by themselves is bold and innovative, but is still not a full recognition of customary tenure. The recognition of rivers as indivisible entities is stated but not clearly implemented.

Māori interests and authority are now more clearly articulated, and Māori may expect to be able to engage in customary practices and restore their traditional relationships with their land more explicitly.

The avoidance of an ownership regime has tempered public concerns about issues such as ownership of flowing water. The formalities are still being completed in the case of the Whanganui River, so the full implications are yet to be felt.

This is an innovative development in tenure arrangements seen by some as providing for the rights of nature, but actually responding to the rights of the Indigenous people. This article may inform others about possible models for more diverse tenure arrangements elsewhere.

Coastal flooding has disastrous consequences on people, infrastructure, properties and the environment. Increasing flood risk as a result of global climate change is a significant concern both within the UK and globally. To counter any potential increase in future flooding, a range of potential management options are being considered. This study aims to explore future coastal management practice for flood alleviation, incorporating the influence of climate change.

The Taf estuary in South West Wales, a macro-tidal estuary which has a history of coastal flooding, was chosen as the case study in this paper to investigate the impact of coastal management interventions such as construction of hard defences, managed realignment or altering land use of affiliated ecosystems such as salt marshes on the complex hydrodynamics and hence flooding of the surrounding areas of the estuary. The study was carried out using a numerical hydrodynamic model of the Taf estuary, developed using the process-based Delft3D modelling software.

The role of the selected management interventions on coastal flooding was investigated using an extreme storm condition, both with and without the impact of future sea level rise. The results highlight the scale of the effect of sea level rise, with the selected management interventions revealing that minimising the increase in flooding in future requires careful consideration of the available options.

This paper explores the highlighted role of coastal management practice in future with the influence of climate change to study how effective alternative methods can be for flood alleviation.
