CASE STUDY: DEVELOPING A LOW-COST FISH PASSAGE SOLUTION TO MITIGATE FOR ENVIRONMENTAL IMPACTS OF WEIRS

  Daniella Montali-Ashworth commenced her CDT-SIS studentship project by adapting a theoretical concept related to fluid dynamics interactions with aquatic plants to better understand fluid mechanics associated with a cylindrical cluster of bristles. From the desk, she moved into the laboratory to test her assumptions, before moving into a highly interdisciplinary realm to explore how …

Improving Fish passage on the Adur

Improving fish passage on the Adur by Rachel Paget Ouse and Adur River Trust Newsletter. Summer 2018. https://oart.org.uk/wp-content/uploads/2018/10/OART-11-Summer-2018-E-Newsletter-1.pdf OART have installed a new fish pass at Haterell’s Bridge, removing a significant barrier to fish passage on the Western arm of the River Adur and facilitating increased, multi-species, fish movement through an additional 2.2km of river.
