Sheffield nestles on the eastern foothills of the Pennines and is sculpted by a dramatic hill-and-valley system formed where five rivers — the Don, Sheaf, Rivelin, Loxley and Porter — converge, producing steep-sided valleys and gritstone ridgelines with much of the urban area built directly onto hillsides…

Birmingham is a snowy city relative to other large UK conurbations, due to its inland location and comparatively high elevation. Between 1961 and 1990 Birmingham Airport averaged 13.0 days of snow lying annually, compared to 5.33 at London Heathrow. Snow showers often pass through the city via the Cheshire gap…

The Lake District is a roughly circular upland massif, deeply dissected by a broadly radial pattern of major valleys which are largely the result of repeated glaciations over the last 2 million years. The apparent radial pattern is not from a central dome, but from an axial watershed extending from St Bees…

The western part of the district in the Vale of York borders on and is drained by the River Derwent. The landscape is generally low-lying and flat although minor ridges and glacial moraines provide some variations in topography. Where there are dry sandy soils there are remnants of historic heathlands and…

In Yorkshire there is a very close relationship between the major topographical areas and the geological period in which they were formed. The Pennine chain of hills in the west is of Carboniferous origin. The central vale is Permo-Triassic. The North York Moors in the north-east of the county are Jurassic in…

Kent was also the location of the largest number of art schools in the country during the nineteenth century, estimated by the art historian David Haste, to approach two hundred. This is believed to be the result of Kent being a front line county during the Napoleonic Wars. At this time, before the invention…

The west of the county lies on more resistant Cretaceous chalk. This chalk is responsible for a sweeping tract of largely downland landscapes that stretches from Dorset in the south west to Dover in the south east and north through East Anglia to the Yorkshire Wolds. The chalk is less easily eroded so forms…

The city, like most of the UK, has a maritime climate highly influenced by the Gulf Stream. Located in the driest region of Britain, Cambridge's rainfall averages around 570 mm (22.44 in) per year, around half the national average, with some years occasionally falling into the semi-arid (under 500 mm (19.69…

Rainfall tends to be associated with Atlantic depressions or with convection. In summer, convection caused by solar surface heating sometimes forms shower clouds and a large proportion of rainfall falls from showers and thunderstorms at this time of year. The wettest months are November and December and on the…

Bath is in the Avon Valley and is surrounded by limestone hills as it is near the southern edge of the Cotswolds, a designated Area of Outstanding Natural Beauty, and the limestone Mendip Hills rise around 7 miles (11 km) south of the city. The hills that surround and make up the city have a maximum altitude…

A study published by Princeton University and McGill University, in 2020, concluded that the Manhood Peninsula is at particularly high risk of flooding as its topography is less than 5 metres (16 ft) above the current mean sea level and that by 2100 Selsey will be subject to permanent inundation.

London's topography is characterized by a gently rolling terrain shaped by the River Thames and its tributaries. The city lies within the London Basin, a natural depression bordered by higher grounds such as the North Downs to the south and the Chiltern Hills to the northwest. The Thames flows west to east,…

Due to its central location in England and altitude range from 27 metres in the south to 636 metres in the north, Derbyshire contains many species at the edge of their UK distribution ranges. Some species with a predominantly northern British distribution are at the southern limit of their range, whilst others…

The city of Exeter was established on the eastern bank of the River Exe on a ridge of land backed by a steep hill. It is at this point that the Exe, having just been joined by the River Creedy, opens onto a wide flood plain and estuary which results in quite common flooding. Historically this was the lowest…

Ashdown Forest is an ancient area of open heathland occupying the highest sandy ridge-top of the High Weald Area of Outstanding Natural Beauty. It is situated 30 miles (48 km) south of London in the county East Sussex, England. Rising to an elevation of 732 feet (223 m) above sea level, its heights provide…

A distinctive feature of the catchment is the marked variation in the topography and character of the landscape, which varies from the upland moorland headwaters of the Dark Peak, where the highest point of the catchment is the Kinder Scout plateau at 634 metres (2,080 ft); through to the intensively farmed…

Little of note happened at Dawlish until the end of the 18th century, when seaside locations on the south coast started to become popular with the wealthy, mainly caused by George III making Weymouth in Dorset his summer holiday residence from 1789. In May 1795, the antiquarian and topographer John Swete spent…

The lake is 1680 yd (1540 m) long and 700 yd (640 m) wide, covering an area of 0.24 mi² (0.62 km²). It has a maximum depth of 70 ft (21m) and an elevation above sea level of 208 ft (62 m). The lake is both fed and drained by the River Rothay, which flows through the village before entering the lake, and then…

Elevations are higher in the north and west, reaching more than 800 feet (240 m) in the Chilterns near Tring. The county centres on the headwaters and upper valleys of the rivers Lea and the Colne; both flow south, and each is accompanied by a canal. Hertfordshire's undeveloped land is mainly agricultural,…
