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.

27th October 2023 Report -

Date: Friday, 27th October 2023

Monitoring Team: Nick Abbott and Peter Sanderson

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



There has been a general increase in sand levels except at the the two 'dry' posts 5 and 6 where there was a slight loss in the foreshore area.

Two previous readings at posts' one and three have been withheld due to an anomaly with the validation which is still under investigation.

Some explanation of the QST for values at post 9B is needed.

The previous reading at -7m was a new record low value of -118%. In the latest QST, that (previous) reading now is listed at 0% because a new record low was established and this becomes the new reference.

The percentage height is always calculated relative to the minimum and maximum sand heights ever recorded but excluding the latest reading. For a reading to be listed as -118 one month and zero the next would appear to be a failing of the QST, but remember the QST is focused on what is happening on the beach NOW; all previous readings become part of history and are used as a reference to help create an awareness of how the beach dynamics are performing.
