The river Thames increases in width the further downstream you go. See related link...
Velocity increases in a downstream direction because more sources of water combine depth and width. A constant flow of water would result in a higher river velocity.
Width will increase as you go downstream due to the process of erosion and sediment deposition. As a river flows, it erodes the banks and bed, widening the channel, especially in areas with lower gradient. Additionally, the river carries sediment that can accumulate in certain areas, further contributing to a broader channel. This dynamic interplay between erosion and sediment deposition leads to the characteristic widening of rivers downstream.
Captain Charles Sturt discovered the Darling River whilst tracing the Macquarie River. Following the Macquarie inland, he came to a smaller river, the Bogan, which, due to the drought, was merely a series of waterholes. Sturt followed the Bogan downstream until he arrived suddenly at what he described as "a noble river", on 2 February 1829. This was the Darling, which Sturt named after Governor Darling.
It depends if you are going upstream or downstream. If you are going downstream, there are no more locks after Teddington and the river will be tidal until you reach the estuary where it discharges into the North Sea. If you are travelling upstream, there are several locks and the river passes through Windsor, Reading and Oxford among other places to reach its source in Gloucestershire.
The Columbia River, The Sacramento River, The Snake River, The Mississippi River, The Hudson River and the Missouri. There are smaller rivers which are navigable but ships can't go in them.
In French practice, the left bank of the river is the one on your left as you go DOWNSTREAM. So, in Paris, the Left Bank is the South of the town.
The processes of erosion and deposition create different river landforms. River landscapes change as you go downstream from the source to the mouth. In the upper course of a river, steep gradients lead to rapid-flowing rivers. In the middlecourse, the river meanders through gentle gradients.
assume river velocity = X mph boat velocity = 20 mph time to go 6 miles downstream = T1 time to go 3 miles upstream = T2 distance = time * velocity downstream: 6 mi = T1 * (boat velocity + river velocity) upstream: 3 mi = T2 * (boat velocity - river velocity) 6 = T1 * ( 20 + X ) 3 = T2 * ( 20 - X ) T1 * ( 20 + X ) = 2 * ( T2 * ( 20 - X ) ) since T1 = T2 then 20 + X = 40 - 2X 3X = 20 X = 6.67 thus, river velocity is 6.67mph
I think that you mean 'lock' and not loch. A lock on a canal or river allows water level to be raised or lowered so that boats can go upstream or downstream.
