Beach Monitoring Reports
October 2023 Report -

Date: Wednesday, 4th October and 18th October 2023

Monitoring Team: Nick Abbott, Peter Sanderson

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



Nick became concerned that the charts from 6/09 and 12/09 mapping were not reflecting what he was seeing where the sand was covering the groins. After checking the sand heights transcribed from propeller (which roughly agreed with my figures) Nick and Peter Sanderson made laser measurements at post 1. This confirmed a very large increase in the sand height. The new chart for post 1 shows the latest laser measurement and the two previous drone measurements.

A limited laser monitoring was conducted by Nick and Peter S on the 18th when unsuitable weather prevented drone monitoring. This was a follow up to the very large accretion measured at Post 1 on 4/10.

The table on the left 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.
