Beach Monitoring Reports

The table shown 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.

September 2023 Report

Date: Wednesday, 6th September 2023

Monitoring Team: Blake, Pat

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



In summary, posts 1-7 show a positive increase in sand height while posts 9 and 10 have lost significant levels. The tip site near post 8 has changed little since July. Post 9 has only two readings possible from the drone and shows a record low level.

Validation of the elevations calculated from the drone images suggests the readings might be up to 10cm below the actual elevations. If the post 8 height is corrected using the validation data, the increase in 'Recent' percentage height is only two points.

The Quick Summary Table is available at the following link. Please book mark this address as it is now the 'go to' place for the latest report on sand levels.

The QST is a dynamic table and its presentation of data changes automatically with time. eg Six weeks from the last monitoring date the 'Recent' data changes colour to grey indicating that a new measurement is due. It is therefore logical to only have this record in one location where it can be quickly updated when ever it changes.
