Burnham-on-Sea in the context of "River Brue"

The River Parrett is a river that flows through the counties of Dorset and Somerset in South West England, from its source in the Thorney Mills springs in the hills around Chedington in Dorset. Flowing northwest through Somerset and the Somerset Levels to its mouth at Burnham-on-Sea, into the Bridgwater Bay nature reserve on the Bristol Channel, the Parrett and its tributaries drain an area of 660 square miles (1,700 km) – about 50 per cent of Somerset's land area, with a population of 300,000.

The Parrett's main tributaries include the Rivers Tone, Isle, and Yeo, and the River Cary via the King's Sedgemoor Drain. The 37-mile (60 km) long river is tidal for 19 miles (31 km) up to Oath. Between Langport and Bridgwater, the river falls only 1 foot per mile (0.2 m/km), so it is prone to frequent flooding in winter and during high tides. Many approaches have been tried since at least the medieval period to reduce the incidence and effect of floods and to drain the surrounding fields.

Brean Down is a promontory off the coast of Somerset, England, standing 318 feet (97 m) high and extending 1+1⁄2 miles (2.5 kilometres) into the Bristol Channel at the eastern end of Bridgwater Bay between Weston-super-Mare and Burnham-on-Sea.

Made of Carboniferous Limestone, it is a continuation of the Mendip Hills. Two further continuations are the small islands of Steep Holm and Flat Holm. The cliffs on the northern and southern flanks of Brean Down have large quantities of fossils laid down in the marine deposits about 320–350 million years ago. The site has been occupied by humans since the late Bronze Age and includes the remains of a Romano-Celtic Temple. At the seaward end is Brean Down Fort which was built in 1865 and then re-armed in the Second World War.

Sedgemoor is a low-lying area of land in Somerset, England. It lies close to sea level south of the Polden Hills, historically largely marsh (or "moor" in its older sense). The eastern part is known as King's Sedgemoor, and the western part West Sedgemoor. Sedgemoor is part of the area now known as the Somerset Levels and Moors. Historically the area was known as the site of the Battle of Sedgemoor.

Sedgemoor gave its name to a local government district formed on 1 April 1974, under the Local Government Act 1972, by a merger of the municipal borough of Bridgwater, the Burnham-on-Sea urban district, Bridgwater Rural District and part of Axbridge Rural District. The district covered a larger area than the historical Sedgemoor, extending north of the Polden Hills across the Somerset Levels and Moors to the Mendip Hills.
