    Subject:   Noosa Spit SEMP - Lower Noosa River Metocean Data Collection




1           Instrument Deployment Summary
To inform the Noosa Spit SEMP, metocean data collection has commenced including:

• The deployment of six tide recorders in the lower Noosa River to continuously measure water level for
    approximately six weeks. This data will be used to calibrate the hydrodynamic model and may also
    provide some valuable information to partially address concerns regarding the published tidal planes.

• Offshore fixed deployment Acoustic Doppler Current Profiler (ADCP) to continuously measure water
  level, current speed, current direction and wave parameters (height, period and direction). This data will
    be used to calibrate both the hydrodynamic and wave models.

• Boat-mounted ADCP measurements have been collected during both neap and spring tidal conditions.
  The measurements (from approximately low water to low water) were taken at Dog Beach, Noosa
    Sound, Munna Point and Noosaville. This data will used to calibrate the hydrodynamic model and
    understand the peak flood and ebb tide currents occurring at Dog Beach.

Figure 1-1 provides a map showing the instrument deployment and boat-mounted ADCP cross-sectional
transect locations. Table 1-1 provides a summary of the instruments. It is anticipated that the deployed
instruments will be retrieved in late April 2019.

Section 2 provides further details on the boat-mounted ADCP measurements
