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.

Commentary:
VCMP Drone Mapping was conducted by Todd from Deakin University on Tuesday 17th September. Bad weather meant that this mapping session was about a month late.
Dune face recession continues along much of the primary dune North East of the general waste tip site. Profiles 9B and 10B along with the QST show the extent of the erosion. Most of the beach appears to be in a loss phase and many of the profiles show a similar sand level to one year ago.
The attached image from VCMP mapping shows a defined Berm just behind the WEDs and confirms the rock structure is still providing protection for the land fill site. Even though water finds its way through between the rocks, the wave energy is reduced so much that the secondary dune remains largely intact, providing protection against erosion of the primary dune which would result in dune recession.
