MidCoast Council is partnering with the University of Newcastle to undertake the studies to better understand how waves and sand interact and move on our coastline.

Researchers will set up equipment on Boomerang, Elizabeth and Shelly beaches from Monday, May 13 and will be on the beaches for most of the day.

"The researchers are measuring surf zone wave parameters such as wave heights and periods, current speeds, and the beach topography," said the field trip leader and senior lecturer from the University of Newcastle, Dr Hannah Power.

These data sets will be used to help answer questions about how waves and sand interact, and how the sand moves around on these beaches, and other NSW beaches, she said. State of the art technology, including laser scanners, pressure traducers and current meters will be used to collect this information.

"Gaining more knowledge and information about how waves behave at specific locations, and how sand is shifted as a result, will help inform council's management of coastal change in these locations," MidCoast Council's Gerald Tuckerman said.

There will be no restriction to public access to the beaches during this research, but beach users are asked to be mindful of the equipment.
