Rivers became more industrialized with the growth of technology and the human population. [19] As fish and water could be brought from elsewhere, and goods and people could be transported via railways, pre-industrial river uses diminished in favor of more complex uses. This meant that the local ecosystems of rivers needed less protection as ...
Rivers get their alluvium from erosion, which carves rock into canyons and valleys. Rivers have sustained human and animal life for millennia, including the first human civilizations. The organisms that live around or in a river such as fish, aquatic plants, and insects have different roles, including processing organic matter and predation.
This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.
The River Exe (/ ˈ ɛ k s / EKS) is a river in England that rises at Exe Head, near the village of Simonsbath, on Exmoor in Somerset, 5.2 miles (8.4 km) from the Bristol Channel coast, but flows more or less directly due south, so that most of its length lies in Devon.
At 37 miles (60 km) long, it is the longest river entirely in Sussex [2] and one of the longest starting in Sussex after the River Medway, River Wey and River Mole. From the series of small streams that form its source in the area of St Leonard's Forest in the Weald , the Arun flows westwards through Horsham to Nowhurst where it is joined by ...
Thus the River Ure and River Ouse can be counted as one river system or as two rivers. If it is counted as one, the River Aire / River Ouse/ Humber system would come fourth in the list, with a combined length of 161 miles (259 km); and the River Trent /Humber system would top the list with their combined length of 222 miles (357 km).

The river has three major tributaries, and many minor ones. For much of its length, it flows in a generally south-west to north-east direction. The historic city of Canterbury is situated on the river, as are the former Cinque Port of Sandwich and the railway town of Ashford. The route of the Stour Valley Walk follows the river.
The River Yare is a river in the English county of Norfolk. In its lower reaches it is one of the principal navigable waterways of The Broads and connects with the rest of the network. The river rises south of Dereham to the west to the village of Shipdham. Above its confluence with a tributary stream from Garvestone it is known as the ...
