Poole Harbour entrance. The Sandbanks (upper in photo) and South Haven (lower) Peninsulas have grown towards the inlet narrowing it from several km in the late Holocene to some 350m at present. All tidal exchange occurs through this inlet generating strong ebb dominant tidal currents and sediment transport. Note the flood tidal delta to the left inside the harbour. It is believed to comprise sands and gravels driven through the entrance by storm waves from Poole Bay.
