Shoreline Erosion Management Plan

A SEMP will provide Council with an understanding of key coastal processes in the study area as
well as a long term action plan to mitigate threats identified to Council assets and land. A SEMP
will address priority erosion issues within the study area and recommend preferred management
options that are underpinned by sound science, coastal engineering principles and community
values, in a process that is supported by State legislative guidance. The proposed scope of the
SEMP includes an investigation of the Noosa River and Main Beach as previous investigations
have shown a clear relationship between these two areas.

In order to complete a SEMP, a Coastal Processes Study is required to support the SEMP with
rigorous science.

The Coastal Process Study would involve deployment of several data collecting units within the
lower Noosa estuary and Laguna Bay, in order to collect detailed information on waves, tides,
currents and water levels. This data will be used to construct a detailed numerical model of the
area to better understand erosive forces, potential sediment transport patterns and the interaction
between the Noosa River and Main Beach. The outcomes of this study, along with consultation
with relevant internal and external stakeholders would underpin the SEMP.
