The River Swale is a river in Yorkshire, England and a major tributary of the River Ure, which itself becomes the River Ouse, emptying into the North Sea via the Humber Estuary. The name ''Swale'' is from the Anglo-Saxon word ''Sualuae'' meaning ''rapid and liable to deluge''. Annual rainfall figures of 1800mm p.a. in the headwaters and 1300mm p.a. in the lower waters over a drop of 148m in 32 km, gives proof to its name.〔(【引用サイトリンク】title=Origin of name )〕 The river gives its name to the valley through which it flows, namely Swaledale. The river and its valley are home to many types of flora and fauna typical to the Yorkshire Dales. Like similar rivers in the region, the river carves through several types of rock and has features typical of both river and glacial erosion. The River Swale has been a contributory factor in the settlements that have been recorded throughout its history. It has provided water to aid in the raising of crops and livestock, but also in the various mining activities that have occurred since Roman times and before. The river is said to be the fastest flowing in England and its levels have been known to rise 3 metres in 20 minutes. ==Course== The source of the River Swale is at the confluence of the Birkdale Beck and the Great Sleddale Beck. The river flows north-north-east past lead mines on its northern bank and the end of Whitsundale and then easterly towards the first of many waterfalls in the headwaters. After flowing over Wain Wath Force the river continues south-east over Hoggarts Leap and Catrake Force near Keld, before it reaches East Gill Force and Kisdon Force. Shortly after Swinner Gill joins the river it swings sharply south towards the village of Muker where Straw Beck joins and the river turns east again. The river flows past Gunnerside towards Feetham where it turns north-east for a short while before returning east past Healuagh, Reeth and Grinton. The river then swings gently south-east and east below Marrick before turning north-eastward and then north past Marske. It eventually returns eastward near Hudswell before it flows past the main town of the valley, Richmond. The river then starts a series of long south-east meanders past Brompton-on-Swale and under the A1 at Catterick Bridge before turning south past Catterick. The river continues long south and south-east meanders past Thrintoft and Morton-on-Swale. As it starts to pursue a more constant southerly flow it is joined by the River Wiske before passing Skipton-on-Swale, Catton, Topcliffe and Asenby. It then flows past Helperby and Myton-On-Swale before joining the River Ure. 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 Swale」の詳細全文を読む スポンサード リンク
