The boundary between defended
and natural sections of this part of the Hampshire coast is marked by a pair
of groynes, either side of the outlet of Chewton Bunny.
|
The clays and gravel mix as they
slide into the beach zone, a mixture termed 'colluvium'. The scale of the
slippage is evident from the human scale object.
|
Groyne H12 marks the boundary
between the Borough of Christchurch and New Forest District Council, who
preside over the wasteland in centre shot.

The undercliff roadway is quite
wide, enough for heavy diggers at least, and is used to facilitate
maintenance on the rock armour of the groynes and beach material between
them.
|
A large car park provides good
accommodation for fieldworkers wishing to visit this site. there is a toilet
and observation pavilion, and ice creams in season. Access is via the
traffic lights in central Highcliffe, opposite G&T's!

A rock groyne, H12, below the
car park. The width of the undercliff is evident.

A luxury house, with an
unpleasantly short garden to the cliff top, here reinforced around a
drainage works, and concrete pipework.
|
More exclusive dwellings, adding
weight to the defended coast argument. Such properties will contribute
highly to the cost-benefit analysis equation.

Naish Farm Holiday
Estate lies between the protected zones of Highcliffe
and Barton-on-Sea. the cliff is a SSSI, a site of special scientific
interest, largely to geologists, as the eroding coastline is constantly
generating fresh exposures. |
 |
|
From the western edge of the
holiday park, the awful gash of chaotic cliff falls, liberally saturated by
recent rain, stretches towards Barton.

Towards the sea's edge the
slides continue; I think I detect a shear plane in this shot!

Towards the west and Highcliffe,
the terminal rock groynes of the defences give way to the receding Naish
Farm coast.

The holiday chalets are visible
here, as are pipes leading to the abyss. Clearly the value of such assets
are not accorded the value of luxury homes, although they probably bring in
more cash to the area in general!

Two chalets have been abandoned
to their fate, and are boarded up. the nearest chalet has 1 metre of
clearance left. In the clefts below lie a pair of picnic tables .. just out
of shot.

|
The boundary of Naish Farm runs
along the cliff top here, but the recent slumping appears quite as regular
as further west.
|
The end of the middle level
roadway on Barton Cliffs, just below the public toilets above.
|
Displaced sheet metal piling and
the surface water build up reveals the cause as well as the extent of the
slippages here.

|
A drainage ditch , probably
constructed to remove liquid from this area, which has seen considerable
slumping.
|
A roadway has collapsed
completely at his point, and slithered off down the hill. Note the crevasses
in the road surface itself.
|
A zoom in on the last shot will
reveal sheet metal piling which has been swept down slope, impotent to
restrain the slumping.

Over the fence and a close up of
the distorted piling. The drainage ditch is visible here, too. The materials
moved underfoot!.
|
Order from chaos in this essay
in rock construction. The Barton groynes start to restore stability to the
coast further east.

A rocky coast, with rip rap in
the bays and rock groynes separating them!
|
More rock, under pressure from
choppy seas. Behind the undercliff road are stone blocks, a graded and
drained slope, another track and then the cliff.
|
A newly-graded slope is probably
in response to a recent slump, evidence for which lies in the foreground.
the Barton shopping parade marks the horizon. |

Rip rap along the coastline,
being attacked by a choppy sea with the wind from the south-west. Looking
east.
|
The parade of shops at the
seafront in Barton, seen from the undercliff track. The variety of textures
and land cover, is dominated by defence works, before a relatively low free
face of cliff. Even so the buildings' future must be suspect.
|
Looking south over the rip rap
from a mini rock groyne. An old wooden groyne still hangs on.

The greensward east of the shops
at the front in Barton. To the left of this shot is the Beachcomber Cafe, a
repository of refreshments and also a display of Barton's history of
erosion, by the New Forest District Council. An ideal place to take stock of
the coast and replenish one's fortitude!
