Modelling eel movement to improve fish pass design
A summary of the PhD research carried out by Tom Padgett into how weirs, fish passes and hydro-electric plants can best be configured to avoid disruption to eel and fish migration.
Rivers and Coasts
What data, evidence and modelling is needed to develop a catchment strategy?
This report aims to help identify the data and modelling needs, and the robustness of evidence, for developing Natural Flood Management strategies in the Skell catchment to reduce flood and sediment risks.
Online catalogue of nature-based flood risk management projects in the UK
This page has been superseded by a new page about our interactive mapping of nature-based flood risk management projects across the UK. You can find the new page here: https://www.jbatrust.org/how-we-help/interactive-mapping/
Improving fish pass design with computational fluid dynamics (CFD) and behavioural models of eel movement
Tom Padgett recently published results from his PhD 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
As part of Eleanor Pearson’s PhD placement with JBA Trust, she 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.
Exploring the origins of watercourses through sedimentary archives
Research outputs from a PhD to estimate flood frequency using documentary and floodplain sedimentary archives to extend flood series.
Flood Inundation Mapping with Data Assimilation
MSc project poster – Zhiqi Hu investigated if observations of floods from satellite images can help us improve the accuracy of forecast flood maps.
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.
River flumes engage and inspire at Peterborough STEM Festival
Two of our hydraulic river flumes were in action at the Peterborough STEM Festival on 13 October as part of a range of fun hands-on activities to celebrate and experience the wonders of science, technology, engineering, and mathematics.
Risk based analysis of small scale, distributed, nature-based flood risk management measures deployed on river networks
The environmental community team up with mathematicians to tackle the challenge of understanding the risks associated with nature-based flood risk management measures deployed on river networks.
