Coastal Erosion
Accelerates
Wave
action
Brothers Jarryd and Tegan du
Toit are caught by surprise
as an extra large wave
pounds into the dunes on
Tuesday afternoon at Palm
Beach, just north of
Alkantstrand. Wave action
has totally undermined the
Zululand coastline over the
past month, sweeping
thousands of tons of sand
into the sea
METRES per day of coastal
dunes and beaches continued
to crumble as huge seas
whipped up by strong
southeasterly winds at
spring tides took their toll
this week.
Sandy beaches are virtually
non existent from
Alkantstrand northwards and,
as onlookers watched, dunes
collapsed before their eyes
causing vegetation and large
trees to plummet into the
sea. The latter are an added
headache to authorities
baffled by nature’s latest
onslaught on the beaches. ‘A
small boat would be in
serious trouble if it
smacked a half-submerged
tree at sea,’ said an
official.
Also
dangerously afloat are
numerous creosote poles
which once formed part of
beach infrastructure.
Meanwhile, arguments and
blame-laying continue as
amenities that have cost
hundreds of thousands of
rands to build look likely
to be washed away at the
next spring tides.
While most concede that
matters beyond the control
of local authorities are at
fault - such as global
warming - others say poor
management of the coastal
system has played its part.
‘Short of building another
pier at the Palm Beach/uMhlathuze
Pipeline area to prevent
sand from moving northwards,
there is no alternative but
to continuously pump sand
into the area,’ said an
ex-municipal official who
has monitored local beaches
for 15 years.
‘Put the dredger just off
the shark nets and keep at
it. At the same time, bring
all the dredge spoil from
new works within the port
and pump that here as well,’
he said. ‘I watched
yesterday as waves broke
over the dune at Palm Beach.
If that dune was to breach,
the sea would flood through
and the entire parking lot
opposite the Triathlon Club
would be under water.’
