Where is the biggest tidal bore?
Qiantang River

How deep is the Mersey River?
30 m
Here is the confluence with the navigable River Weaver. The Mersey Estuary continues through the ‘Narrows’ a straight narrow channel with depths of up to 30 m driven by a change in geology. It forms the Outer Estuary, a large area of inter-tidal sand and mud banks as it flows into Liverpool Bay on the Irish Sea.

What causes a river bore?
A tidal bore is a rare natural phenomenon in which an incoming tide creates a wave of water that travels up along a river or a narrow bay causing water to flow against the river’s current.
How big is the tidal bore on the Mersey?
THE TIDAL BORE ON THE RIVER MERSEY Most people have heard of the Severn Bore and flock to witness (or surf) its famous, huge wave on the Spring tides. But few know the River Mersey has the second largest tidal bore in Britain and can reach up to 1.7 meters when a very high tide (over 10m at Liverpool) is expected.
How fast does the water come in on the Mersey?
The water comes in fairly rapidly and it has been estimated that it can reach speeds of eleven miles per hour on the Mersey. A bore is a large wave at the foremost point of an incoming tide as it travels up-river.
Why are tidal bores important for river estuaries?
River estuaries with a tidal bore are generally the most important feeding grounds for estuarine wildlife. As the tide approaches the riverbed is scoured and the rich mixture is aerated and redeposited on the tide’s retreat.
Which is the second highest tidal range in Britain?
