SCOPAC Sediment Stores & Sinks Study

Channel Coast Observatory: £25,000 (2011-2014)

The primary aim of this project was to identify sediment stores and sinks across the SCOPAC region for future recycling operations. There are large cost savings to be had by using locally sourced material for beach replenishment and recycling schemes.

The project presents sediment accretion and erosion for beaches, ebb deltas, landward sinks and offshore shoals using best available data. The main focus of the report is on the active sediment stores, particularly those areas undergoing large changes in volume or area.

About the fly-through presentation

The video above presents the final sediment stores and sinks across the SCOPAC coastline, showing:

Beaches

Beach accretion is shown for the earliest to most recent epoch with management practices removed. The scale of the mapping does not lend itself well to presenting the beach stores, however, the detail can be found in Section 3.1 and Appendix E of the report “Evolution of Coastal Sediment Stores and Sinks across the SCOPAC region”

Ebb tidal deltas

Ebb tidal delta accretion is shown for the earliest to most recent epoch which varies for each site. Further information can be found in Section 3.2 of the report.

Landward sinks

Constant areas and areas of gain in sediment for earliest to most recent available data. Further information can be found in Section 3.3 of the report.

Offshore shoals

Constant areas and areas of gain in sediment are shown for earliest to most recent available data. Further information can be found in Section 3.4 of the report.
