Estuaries
Geography: AQA GCSE, topic 3.3.14
Estuaries
Estuaries are found in tidal areas at river mouths (where the sea meets a river).

What happens at high tide in estuaries?
- At high tide, the river overflows its banks.
- Because the water is moving slowly at this point, the sediment it is transporting gets deposited.
- These sediments build up over time to form large mudflats.

What happens at low tide in estuaries?
- At low tide, the sea retreats and the mudflats are exposed to the air.
