Beach Monitoring Reports
12th December 2023 Report -

Date: Tuesday, 12th December 2023

Monitoring Team: Dept of Energy, Environment and CLimate Action

Analysis & Report: David Bills-Thompson, PFCG Technical Officer and Data Co-ordinator



The Department of Energy, Environment and Climate Action conducted VCMP mapping around Port Fairy Bay on 12th December 2023.

Generally there has been an increase in sand levels however the dune crest behind Post 9 has receded by about one metre; refer to chart 9B.pdf for the details.

Validation of the measurements by Elevation History in 'Propeller' suggest that elevations could be high by 3 - 5 cm. depending on location. Comparison with laser measurements on the same day at posts 1, 2 and 3 are also slightly less than the drone mapping. On charts 1, 2 and 3, the green lines are the laser measurements. This investigation is ongoing.


The table above is derived from actual measurements of the beach sand elevation at typical points along East beach. The colours are used to provide an approximate indication of the sand level along the beach compared with historical levels. The range of sand levels and the values at which the colours change are shown in the colour legend at the bottom of the table.

The percentage represents the current sand height compared to the historical minimum and maximum heights ever measured at that location since 2013. These values are calculated from the measurements used to produce the profile charts that give additional information about the sand dynamics at that monitoring point.

These three columns give an overview of the sand level now, how it has changed since the previous measurement and how it compares to last year's results.

A positive number in a red square is usually not a concern but if the number is negative, it indicates that a new low sand level has been detected and further consideration of all the data at that point should be investigated.
