Risk assessment of the production of seaweed in the Netherlands; food safety and nature

open access: yesFood Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Seaweed is seen as an important source of alternative proteins for a sustainable food system and food security. The cultivation of seaweed is therefore encouraged by the European Union (EU) and also by the Dutch government.In the Netherlands, seaweed is farmed on small scale in the Southwest Delta, the Wadden Sea and the North Sea. Despite the

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

open access: yesPolymer Composites, Volume 47, Issue 5, Page 4102-4126, 10 March 2026.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

The Variation in Wake Structure of a Tidal Stream Turbine with Flow Velocity [PDF]

open access: yes, 2013
A combined Blade Element Momentum - Computational Fluid Dynamics (BEM-CFD) model is applied to a 10 m diameter tidal stream turbine blade and the supporting nacelle and tower structure in a 700 m long rectangular channel. The modelling approach is computationally efficient and is suitable for capturing the time-averaged influence of the turbine on the ...

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Shrouded Wind and Water Turbine Analytical Model Extensions for Tip Gaps, Center Bodies, and Flow Blockage

open access: yesWind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This paper provides improvements to a previously presented simple, accurate, lower order analytical model for predicting the performance of horizontal‐axis shrouded turbines for a wide range of shroud airfoil shapes varying in length, camber, and thickness. The new, extended model incorporates explicit quantitative predictions of those effects

Study on the Wake Characterization of a Horizontal-Axis Tidal Stream Turbine Utilizing a PIV System in a Large Circulating Water Tunnel

open access: yesEnergies
In this study, a particle image velocimetry (PIV) system was used in a large circulating water tank to investigate the wake of a horizontal-axis tidal turbine model, focusing on minor blockage effects and scale influence.
