The Derwent is a river in the county of Derbyshire, England. It is long and is a tributary of the River Trent which it joins south of Derby. For half its course, the river flows through the Peak District. Much of the river's route, with the exception of the city of Derby, is rural. However the river has also seen many human uses, and between Matlock and Derby was one of the cradles of the Industrial Revolution, providing power to the first industrial scale cotton mills. Today it provides a water supply to several surrounding cities, and its steeply sided valley is an important communications corridor through the uplands of the Peak District.〔(【引用サイトリンク】 River Derwent )〕 Because of its scenic qualities, the valley of the River Derwent sees many tourist visitors. The upper reaches pass through the Peak District National Park, whilst the middle reaches around the old spa town of Matlock Bath which attracts tourists because of its souvenir shops and amusement arcades, together with attractions such as the Heights of Abraham and its cable car.〔〔(【引用サイトリンク】 Matlock Bath )〕 It has been theorised that the name "Derwent" is Celtic and means "a valley thick with oaks" - cf. Welsh ''derwen'' ("oak"). An alternative etymology suggests the name originates from the Celtic ''dwr gwyn'', meaning "white water". ==Course== The River Derwent rises at Swains Greave (590 metres above sea level) on the eastern flank of Bleaklow, opposite Howden Moors, and some east of Glossop.〔 It flows through the Upper Derwent Valley with its three consecutive reservoirs. In order downstream these are the Howden Reservoir, Derwent Reservoir and Ladybower Reservoir. Howden Reservoir is also fed by the River Westend, whilst Ladybower Reservoir is also fed by the River Ashop. In both cases the former confluences of the two tributaries with the River Derwent are now submerged below the respective reservoirs.〔 Further south, the Derwent passes by the village of Bamford, where it is joined by the River Noe. Below this confluence, it flows through Hathersage, Grindleford, Calver and Baslow, and through the estate of Chatsworth House, before it is joined by the River Wye at Rowsley.〔 After passing through Darley Dale, the Derwent reaches Matlock, where, at an oxbow, it collects the great millstream Bentley Brook. It then flows past the villages of Matlock Bath, Cromford, Whatstandwell, and Ambergate, where it is joined by the River Amber.〔 Below Ambergate, the river flows by the town of Belper and the villages of Milford and Duffield. It then enters the city of Derby near Darley Abbey and flows through the centre of the city. The river ends at Derwent Mouth, east of Shardlow, where it flows into the River Trent at a height of above sea level; a total drop of .〔 Its course meanders somewhat, especially in its lower reaches, adding to its apparent length of . Its waters ultimately reach the North Sea via the Humber Estuary.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「River Derwent, Derbyshire」の詳細全文を読む スポンサード リンク
