The danger of grounding that the extreme tidal range posed to shipping caused a decline in Bristols importance as a port.

All Bristols rivers drain to the River Avon, which in turn flows into the Severn Estuary.

Since the latter has the second highest tidal range in the world (the highest is in the Bay of Fundy by the way) this creates further drainage problems for the city.

In 1825 the Mylnes Culvert was constructed to take this flow under the Floating Harbour to discharge into the New Cut.

Major schemes have continued in the 200 years since.

The Northern Storm Water Interceptor tunnel, built in the 1950s, is 12 km long and takes water from the Frome at Eastville and discharges it in the Avon Gorge.
