Beach Monitoring Reports
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.

Analysis & Report: David Bills-Thompson, PFCG Technical Officer and Data Co-ordinator
Commentary: The dunes north of the tip site continue to be active although dune recession is minor compared to recent events. The apparent sand accretion behind the dune crest in 9B and 10B is most likely an artefact produced by foliage which is known to give unreliable sand elevations.
The image below of behind the WEDs (From drone mapping) shows water penetration though the rocks but with greatly reduced energy and forming a berm in the secondary dune preventing water reaching the primary dune. This is a demonstration of the WEDs doing its job, still.
Examination of the QST confirms detrimental activity is confined to the area south of the tip to the Parks Vic carpark (posts 7-10) while areas closer to the town including the Night Soil site are in good shape.
The QST indicates that several posts are due for monitoring; Since the DEECA policy change, no full crescent (Includes 11 and 12 and to Mills Reef) monitoring has been done for 15 months; posts 3, 9 and 10 are part of the Swinburne data set with a monitoring frequency of 21 days. Due to an obscure technical fault the monitoring of these posts 8 days ago could not be used. Hence the listing as 'Out of Date'.
