Protected foreshore, from Mabel Greville Breakwater to the Naze A-frame Breakwater

 

 

The Mabel Greville breakwater at a very low tide; levels seem to favour the south side of the groyne.

From the defended coast 200m north of Mabel Greville; drainage inspection hatch in the foreground, centre, and more of the blockwork defences, centre and right.

The concrete blocks are held by sheet piling and wooden piles; the graded slopes behind feature in the centre shot, with affluent housing just showing on the ridge line.

Winter seas have aggraded the beaches with shingle as the Naze Tower is approached.

1280-DSC06716.jpg

 

 

 

 

As the tide was so low it was an excellent opportunity to view the cliffs from the seaward, across a basement of clay, only overlain by shingle in a narrow band of beach.

Walton town to the south, across the 'cloughs' of clay.

Swivelling from views to the south, on the left, towards the north on the right.  The relationship between the protected cliffs, the breakwater, and the undefended cliffs can be established.

I could see a major cliff fall has taken place, but also wanted to record the unusual low tide exposing the end of the breakwater. The steep concrete pathway (with pedestrians and the Tower in the background) from the undercliff to the cliff top is getting to be within 5-6 metres from the edge of the active cliff erosion.

Cliff falls at the Naze Breakwater

 

 

The new cliff fall is seen over the rip rap protecting the A-frame breakwater; it can be seen to be outflanking these defences.

The first embayment northwards from the protected coast has suffered a fall, seen by the many levels of dying grass on the rotational slumps being carried forward towards the beach. The beach has been lowered over the last year or so and is regularly washed over its full width, removing cliff falls.

1280-DSC06734.jpg

857-DSC06735.jpg

1280-DSC06736.jpg

 

The centre photo shows that erosion of the slumping is recent and active, although in other parts of the cliff this has not been the case.

857-DSC06737.jpg

1280-DSC06741.jpg

 

 

 

857-DSC06738.jpg

 

 

 

On the left a mobile flow has made its way to the beach, draining the hollows created by the slumping. Centre and right photographs show exposure and erosion of the clay - looking like basalts when dried out!

857-DSC06742.jpg

857-DSC06744.jpg

The position of the pillboxes remains the prime marker of recent erosion, here seen with various backdrops of recent falls.

1280-DSC06746.jpg

This sequence shows a shear plane in the clay, scraped smooth and with scratch marks, where the crag has slid down over it in a surge towards the beach.

1280-DSC06751.jpg

857-DSC06754.jpg

1280-DSC06753.jpg

 

 

 

On the left an embayment spews more material, in an area where saturated crag slides freely from cliff falls.

 

 

On the right, slumps from the low cliffs deliver further woodland to the beach.

1280-DSC06757.jpg

 

 

 

 

1280-DSC06761.jpg

 

The site of what was clearly extensive docking facilities at the north of the Naze peninsula. Erosion has been less effective on the well-bound platelets of clay, than the larger grain size of the material at the base of an old construction. The Hjustrom Curve in action!

Northwards to the Felixstowe skyline.

The old sea wall and the lagoon at its front.

The lowlands to the north of the Naze and adjoining Hamford Water. The vegetation cover is of marsh, rough grassland and scrubby woodland .. and is managed behind sea defences.

1280-DSC06775.jpg

 

1280-DSC06774.jpg

 

 

 

 

The extent of the sand and gravel beach is limited, as seen against the extensive area of wave-cut platform that is clay. The shear-plane slip is seen in the centre and on the right, ad is well-marked by the two concrete gun-mounts.

Cliff interfluve and probable unconformity!

1280-DSC06781.jpg

 

 

 

 

The concrete standing on the cliff top near the cafe is almost gone, falling whole as seen in the centre shot! Slumping blocks are seen quite near the cliff top, but no longer accessible from it.

1280-DSC06784.jpg

 

857-DSC06786.jpg

1280-DSC06785.jpg

 

 

 

 

Dramatic pillars of crag less than a foot thick!

1280-DSC06790.jpg

 

 

 

 

Only the southern section of the first embayment has failed, but it is this area that is most crucial, threatening the cafe and the concrete steps down the cliff.

1280-DSC06787.jpg

857-DSC06795.jpg

 

 

 

1280-DSC06788.jpg

 

Already the chasm between the cliff top and the surging rotational slumps is considerable; the free face is again unsupported and able to fail. The new wooden railing, right, will be a good marker of erosion for some months.

1280-DSC06791.jpg

 

 

 

857-DSC06792.jpg

1280-DSC06794.jpg

 

From a ledge half way down the cliff, the pillars are just about visible, as is the structure of slumps and free faces .. and the area where rainwater will provide the weight and reduced adhesion for a mobile flow.

1280-DSC06799.jpg

The last of the concrete apron, left, is near the top of the beach access steps, centre. The cliffs are outflanking the defences, right, and are now nearly in line with the Tower Breakwater.
