- •
We model the impact of partial barriers and flow on river connectivity.
- •
A novel method was used to integrate hydraulic and connectivity modelling.
- •
The output was highly dependent on how barrier passability was modelled.
- •
Flow can have a strong and complex effect on connectivity.
- •
Greater understanding of combined effect of barriers urgently needed.
