Yes, there are groynes along the Holderness Coast in East Yorkshire, England. These structures are used to reduce coastal erosion by trapping sand and sediment, helping to protect the shoreline from the powerful waves of the North Sea. The groynes have been part of coastal management efforts in the area, which is known for its rapid erosion rates. However, their effectiveness and environmental impact are subjects of ongoing debate.

The Holderness Coast is approximately 20-30 miles east of Hull, depending on the specific location along the coast.

The Holderness Coast in the UK is primarily composed of soft sedimentary rocks such as clay, sand, and gravel. These rocks are easily eroded by the sea, causing the coastline to retreat at a rapid rate.
The cliffs on the Holderness Coast are mostly made up of chalk and therefore erosion happens quickly. Due to the fact that groynes were put in place to protect the small village of Mappleton that is on a clifftop, this has meant that less beach material can move downstream and therefore further erosion takes place further downstream.

The Holderness Coast has employed various methods for coastal protection, including hard engineering solutions like sea walls and rock armor to absorb wave energy and prevent erosion. Additionally, groynes have been constructed to interrupt sediment transport and build up beaches. Soft engineering approaches, such as beach nourishment, have also been used to replenish eroded beaches with sand. These strategies aim to balance the need for immediate protection with long-term sustainability of the coastline.
Spurn Point and the area around Aldbrough are areas in the Holderness Coast that are particularly exposed to deposition due to the prevailing northeast winds and the longshore drift process. These areas experience significant erosion, leading to the deposition of sediment along their shores.
