Modelling fish passes can present different challenges to modelling flood flows. Fish require a range of conditions to stay happy and migrate upstream to spawn, and different species have different requirements.

In this webinar, Tim Paddison, Principal Modeller at Binnies, focuses on two sites located on an upland stream in South Wales, for which Binnies designed fish passes as part of a wider project commissioned by Natural Resources Wales.

This webinar demonstrates how Flood Modeller can be used to test different options, aid the refinement of fish pass designs, assess the impacts on flood risk and ultimately lead to their successful construction.
