Improving fish pass design with computational fluid dynamics (CFD) and behavioural models of eel movement

Improving fish pass design with computational fluid dynamics (CFD) and behavioural models of eel movement

Tom Padgett is nearing the end of his PhD research, sponsored by JBA Trust, and recently published results from his research in the Royal Society Open Science Journal. Tom used the flexibility of computational modelling to test different eel tiles under several different conditions and eel life stages. Overall, passage efficiency decreases with increasing flow and steeper installation angles; it increases as elvers get larger, and older.

Comparing sediment transport in hydraulic models

Comparing sediment transport in hydraulic models

As part of Eleanor’s placement with JBA Trust, she has investigated whether the outputs from pre-existing flood risk hydraulic models can be used to evaluate the geomorphological impact of a flood. Results from her work are presented in this poster.

Geomorphological effectiveness of floods to rework gravel bars: insight from hyperscale topography and hydraulic modelling

Geomorphological effectiveness of floods to rework gravel bars: insight from hyperscale topography and hydraulic modelling

A new study shows how the topographic and sediment data collected using terrestrial lidar surveys can be used to provide boundary conditions in a range of widely accessible flow models and could help add further insight to the hydromorpological analysis of a river reach.
