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.
July 2023 Report
Date: Wednesday, 5th July 2023
Monitoring Team: Staff from the Department of Energy, Environment and Climate Action
Analysis & Report: David Bills-Thompson, PFCG Technical Officer and Data Co-ordinator
Commentary: Across the area monitored from post 1 to post 10 there has been a relatively large loss of sand.
The Wave Energy Dissipation structures (WEDs) image taken from processed drone images show the formation of a Berm behind the rocks indicating there has been heavy wave activity but sufficiently attenuated by the rocks to not encroach on the dune toe. The WED is still working.
The image also shows a comparison of the sand levels between the last two mappings.
Profiles of the ten posts show the usual detail from which the QST is derived.
