Happisburgh August 24 2010

The usual place to start for a photo-shoot of Happisburgh is the destroyed lifeboat ramp. Here the concrete has been undermined and has been left, in some areas, hanging against the cliff. Behind are other reminders of erosion, namely the ruined revetments and newer rip-rap.

From the cliff top in front of the caravan and camping field, and the beach steps in the centre.

To the north the cliffs are edging back from the line of revetments - and the pillbox makes a good marker!

Still in the area of the old lifeboat ramp, and its tangled mass of concrete.

A pronounced plinth of clay basement has developed in front of Cliff Road, where unglamorous buildings are about to fall.

The shoreline still has ineffective revetments, but also new rip-rap defences, centre.

The rip=rap is low in the water in places, and its line is by no means complete, but it is soaking up a lot of energy, nevertheless.

Just a few of the old steel reinforcement rods litter the beach.

There has been little recession in front of cliff Road and, in places, vegetation has colonised the less severe slopes.

The headland at Cliff Road is being worn back, left, but the wide expanse of beach to the south appears to be accumulating!

The wide beach berms in 'Happisburgh Bay, together with the handiwork of Sand Martins, centre.

The tide was turning when these shots were taken, and  occasionally a large wave would come over the outer beach.

Looking towards the defences at Cart Gap, where beach accumulation was to become more evident.

A deep backwater has etched out a channel that cuts through a gap in the groyne at the northern end of the Cart Gap defences.

Older defences have been swamped by an  accumulation of beach material, cut into by the lateral channels.

Harder defences predominate south of the access at Cart Gap, with groynes doing a big job, left, but displaying the pressures of beach entrapment by the need to reinforce the lee of the groyne with rip-rap.

Groynes made from back-to-back sheet piling filled with concrete, left. On the right the rip-rap in front of the concrete sea wall is being buried by sand.

The walk was to the most northerly of the reefs at Sea Palling. At this state of tide the tombolo of sand fell just short of the reef.

On the left is the brash-line of the last high tide on the sand tombolo. On the right is a vehicular beach access point being filled up by blowing sand.

The encroachment of the sand spilled over the dune crest to the lane beyond. On the right sand has gummed up steps up to the sea wall.

The steel sheet piling at the northern end of the Cart Gap defences had been outflanked by the sea, but had then been reinforced by rip-rap. The latest development is the invasion of blown sand from the aggrading beach.

The views northwards, towards Happisburgh, show rising levels of upper beach and some vegetation on stable slopes.

This theme of sand accumulation is evident from the cliff top, if not so clearly from the sea's edge. Unfortunately, I hit the wrong button on the camera and lost the proto-dunes developing in the northern part of the bay!
