The high tide @ 11.05am on Sunday 9th of December coincided with SW wind direction. This resulted in a lot sediment being shifted off the beach on the southern boundary of our island.....
A report by Alan Burgess 
Current Picture On Sunday 9th of December at 11.05am there was a storm surge on top of the high tide. This happened because the wind direction came up the line of the Solent from the South West. A storm surge is when the wind interacts with the sea surface in such a way as to cause an extra high tide. This extra energy results in high levels of erosion. In the scale of things this is not an unusual event. We often get storms in winter, nothing new there. This event shifted 100’s of tonnes of beach sediment and exposed the base of the sea defence. 
Does Portsmouth have a weakness in its sea defence system? What does need our scrutiny, is the current state of our sea defence. We would like all of you who live in Portsmouth, and go for an occasional walk on the beach at Southsea to watch how the beach is changing, and to watch how the sea defence structures are responding to the current storm energy. Are storms becoming more intense? Are the sea defences crumbling. How much of a problem is this? Surely it is just a matter of slapping on a bit more concrete.
