Hemsby Hole is not in Hemsby, but just off its coast, quite close to the beach. It is a relatively deep seabed feature, parallel with the beach, running from near Winterton-on-Sea to near Caister-on-Sea. And it is getting deeper, according to the UK Hydrographic Office (ukho.gov.uk) survey which compared features in 2005 with those in 1999.

A layman wonders if this deepening is caused by the same complex of processes which robs Hemsby of its natural coastal protection - large sand dunes.

Why would massive sand dunes, which must have taken years to build up (give or take seasonal adjustments), start and continue to erode rather than keep accreting on balance?

How many impartial scientific studies have there been into the effects of dredging for sand and aggregates on the whole coastal ecosystem and geomorphology? Any references please (suitable for a layman to grasp)?
