Southsea Tracer Pebble Study

Southsea Tracer Pebble Study 2023 - 2024

Our Research Team have recently deployed 700 tracer pebbles across seven sites along the Southsea frontage, stretching from The Pyramids to Fort Cumberland. Tracking the movement of these tracer pebbles will help to provide important information on sediment transport rates and direction, including the location of any sediment transport convergence (where material accumulates) or divergence zones (where material disperses from). It will also give an indication of the behaviour of the newly imported material pumped ashore by the Sospan Dau in September 2023 as part of the Southsea Coastal Scheme works. The results from this tracer pebble study will feed into the Southsea Beach Management Plan that is currently being developed as part of the Southsea Coastal Scheme and allow our team to gather evidence to support numerical modelling and ongoing studies along the frontage.
