Covers the behaviour of rivers, danger levels at bridges, duties of bridge watchmen, and river training works — Guide Bunds, Spurs (Groynes), Marginal Bunds, Closure Bunds, and Assisted Cut-Offs — used to protect bridges and approach banks from flood damage.
River Training Works
- Guide Bunds direct river flow away from bridge approaches; Spurs (Groynes) project into the flow to deflect it from banks.
- Marginal Bunds and Closure Bunds protect specific vulnerable stretches, while Assisted Cut-Offs redirect a river's course entirely.
