COUNCIL TO TRIAL NEW<br />
TECHNIQUE TO NOURISH<br />
OUR BEACHES<br />
A technique new to the Sunshine Coast will<br />
be used to address erosion at one of the<br />
region’s most popular beaches.<br />
Sunshine Coast Council has<br />
announced it will trial an innovative<br />
method of sand nourishment at<br />
Maroochydore to protect the popular area<br />
from the effects of severe weather.<br />
The technique, called nearshore<br />
nourishment, has not been used in the<br />
region before and it involves importing<br />
sand from outside the area and placing it in<br />
the water, about 300 metres off the beach.<br />
Waves, currents and tides will then<br />
deposit the sand onto our beaches,<br />
providing an additional buffer to future<br />
storms and coastal erosion. The traditional<br />
method is to beef up the beach itself, rather<br />
than drop sand offshore.<br />
Sunshine Coast Council’s environment<br />
portfolio councillor Peter Cox says the<br />
Coastal Hazard Adaptation Strategy guides<br />
the Council’s work to manage our region’s<br />
beaches from the risk of future erosion.<br />
“A lot of work has gone on behind the<br />
scenes over several years to inform the<br />
long-term management of our coastline,”<br />
he says. “We are using coastal data captured<br />
through wave buoys, beach surveys,<br />
NEWS<br />
hydrographic surveys, ecological<br />
monitoring, and wind data to shape the<br />
project.This is in addition to studies that<br />
have shown that there is a limited supply of<br />
sand on the Sunshine Coast.<br />
“Maroochydore Beach has been subject<br />
to significant erosion events over the years<br />
and adding new sand from outside the<br />
region, such as the Spitfire Channel in<br />
Moreton Bay, will help nourish the area and<br />
protect from further erosion.<br />
“The trial will supplement the existing<br />
sand re-nourishment program that involves<br />
collecting sand from the Maroochy River<br />
and pumping it onto the beach. Trialling<br />
the new technique will assist us to make<br />
evidence-based decisions about the future<br />
management of our coastline.”<br />
