Having two Boulder Rivers in Montana often leads to confusion, with some descriptions mistakenly combine the two. The Boulder River in Southwest Montana begins in Jefferson County, northwest of the town of Boulder. The river flows through a canyon along Interstate 15, at the town, it loops to the south, leisurely meandering through the Boulder Valley until it joins the Jefferson near Cardwell. In late summer, irrigation needs reduce the river's already meager water still further, making fishing and floating difficult.

Pharpar (or Pharphar in the Douay-Rheims Bible) is a biblical river in Syria. It is the less important of the two rivers of Damascus mentioned in the Book of Kings (2 Kings 5:12), now generally identified with the A`waj (i.e. crooked), though if the reference to Damascus be limited to the city, as in the Arabic version of the Old Testament, Pharpar would be the modern Taura. In the early Baedeker Guides it was identified as the Al-Sabirani, a fairly downstream tributary of the A`waj.

The Barada (Arabic: بردى‎ / ALA-LC: Baradá; Greek: Chrysorrhoas) is the main river of Damascus, the capital city of Syria. It flows through the spring of ‘Ayn Fījah (عين فيجة), about 27 km north west of Damascus in the Anti-Lebanon Mountains, but its source is Lake Barada, located at about 8 km from Zabadani. The Barada descends through a steep, narrow gorge named "Rabwe" before it arrives at Damascus, where it divides into seven branches that irrigate the oasis of Ghouta (الغوطة). The 'Barada' name is thought to derive from 'barid', i.e. 'cold'.

The Hawkesbury River (also Hawkesbury-Nepean River), is a semi–mature tide dominated drowned valley estuary located to the west and north of Sydney, New South Wales, Australia. The Hawkesbury River and its associated main tributary, the Nepean River, virtually encircle the metropolitan region of Sydney.

The Derwent is a river in Tasmania, Australia. The river rises in the state's Central Highlands and descends more than 700 metres (2,300 ft) over 200 kilometres (120 mi), flowing through Hobart, the state's capital city, before emptying into Storm Bay and flowing into the Tasman Sea. The Derwent River valley was inhabited by the Mouheneener people for at least 8,000 years before British settlement. Evidence of their occupation is found in many middens along the banks of the river.

The Alster is a right tributary of the Elbe river in Northern Germany. It has its source near Henstedt-Ulzburg, Schleswig-Holstein, flows somewhat southwards through much of the Free and Hanseatic City of Hamburg and joins the Elbe in central Hamburg.
