Poole Bay

Poole Bay is a bay in the English Channel, on the coast of Dorset in southern England, which stretches 16km from Sandbanks at the mouth of Poole Harbour in the west, to Hengistbury Head in the east. Poole Bay is a relatively shallow embayment and consists of steep sandstone cliffs and several 'chines' that allow easy access to the sandy beaches below. The coast along the bay is continuously built up, and is part of the South East Dorset conurbation, including parts of the towns of Poole, Bournemouth and Christchurch. The bay is often erroneously referred to as Bournemouth Bay, because much of it is occupied by Bournemouth.Measures to prevent coastal erosion have been deployed throughout the 20th century. Concrete seawalls and groynes allowed the construction of homes and roads on the clifftops, but prevented natural supply of sand and gravel to the shore. From 1970 to 2000 over 1.5 million m³ of sand was used to replenish the beaches at Bournemouth and Poole. Many of the beaches along Poole Bay were replenished during the winters of 2005 and 2006 with 1.1 million m³ of sand dredged from Poole Harbour and 700,000 m³ of sand dredged from a Licensed Area off the Isle of Wight. In 2015 a 17-year £43.7million project was approved to protect the beaches from further erosion over the next century. The plans involve replacing the groynes and adding new ones and replenishing the beaches with 210,000 cubic metres of sand and gravel every three years.
