Bed Level Change Measurements at Tollesbury Managed Realignment Site 1995-2007

Twenty fixed transect positions measured monthly to bimonthly from 1995 to 2007 to investigate silt accumulation after coastal realignment. Data was collected to the nearest millimeter using a ruler by the data author. The work was funded by the UK Department for Environment, Food & Rural Affairs.

Use Cases

• Analyze temporal trends in bed level change from monthly and bimonthly transect measurements to assess silt accumulation rates.
• Model the impact of managed sea wall breaching on sediment deposition using the fixed transect positions as spatial reference points.
• Correlate measurement frequency changes (monthly to bimonthly to biannual) with observed bed level stability over the 12-year period.

Strengths

• Long-term monitoring over a 12-year period from 1995 to 2007.
• High-precision measurements recorded to the nearest millimeter.
• Data collection follows a structured protocol with twenty fixed positions along transects.

Limitations

• Unknown sample size (row count) and specific data structure (columns).
• Data collection frequency decreased over time (monthly to biannual), potentially reducing temporal resolution later in the series.
• Geographic scope is limited to a single managed realignment site in the Blackwater estuary, UK.
