Two-Dimensional Numerical Modelling of a Moored Floating Body under Sloping Seabed Conditions

Journal of Marine Science and Engineering, 2020
A coupled floating body-mooring line model is developed by combining a boundary element model for a two-dimensional floating body and a catenary mooring line model.

A Systemic Model for Understanding Business Interactions With Biodiversity and Ecosystems

Business Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity loss and ecosystem degradation represent critical threats to human well‐being and economic resilience, challenging businesses to understand and manage their interdependence with natural systems. This study develops a systemic framework—the BioModel—that elucidates the reciprocal relationship between businesses, biodiversity, and ...

Making Value‐Chain Risks Visible: Extending ENCORE for Systemic Insights

Business Strategy and the Environment, EarlyView.
ABSTRACT Businesses in all sectors, including downstream segments, depend on biodiversity and the ecosystem services it sustains, yet firms also exert pressures that accelerate biodiversity loss. The latter generates material risks for both companies and their financial stakeholders.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Analytical solutions for dynamic response in poroelastic seabed under second-order Stokes waves

Yantu gongcheng xuebao
Based on the theory of the second-order Stokes waves, the dynamic response of a poroelastic seabed induced by nonlinear ocean waves is investigated. The governing equations for the seabed are established in Cartesian coordinates using the Biot's general ...

Numerical investigation of non-cohesive seabed response around a mono-pile by crossing wave-current

Water Science and Engineering, 2022
The interaction between waves and currents in the ocean often complicates the flow field around structures. In this study, a three-dimensional integrated numerical model was established to investigate the seabed response and liquefaction around a mono ...

Ocean Governance and Marine Conservation: Institutional Work as a Lever for Ocean Sustainability

Environmental Policy and Governance, EarlyView.
ABSTRACT Ocean governance presents one of the most complex environmental policy challenges of our time, requiring coordinated action across multiple scales, sectors and stakeholder groups. This paper applies institutional work theory to systematically examine how actors create, maintain and disrupt the governance arrangements underpinning ocean ...

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

Limnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Formation Control With Obstacle Avoidance of Underwater Swarms Based on Relative Visual Feedback

Journal of Field Robotics, EarlyView.
ABSTRACT Underwater multi‐robot and swarm systems require advanced methodologies for controlling collective behavior. Conventional single‐robot techniques, such as tethering, sonar imaging, and acoustic localization, are not scalable or effective for swarm applications.
