From a longitudinal view, it is the deepest part of the riverbed from the source of the mouth. It is line of steepest descent along the streambed and is almost alway the line of fastest flow in any river
A thalweg is the lowest elevation in a valley or watercourse.

The maximum velocity of water typically occurs at the center of the stream where the flow is deepest and least affected by friction from the streambed and banks. This is known as the thalweg or thalweg line.
The velocity of a river is typically highest in the center of the channel, where the water has the least amount of friction with the riverbanks and bed. This is known as the thalweg.
this principle is used to form international water boundary between nations having dispute over an region, it is also binding upon LAW OF SEA.
The "Main Channel".
Thalweg
A fast flowing stream is called a rapid. Rapids are where the water flows downhill very fast and over underwater obstacles.
the side to sidecurves in a riverthat occur whenthe land is relativelyflatAs the river erodes quicker at the thalweg (the path of the fastest flowing water) and slower on the opposite banks, where it is depositing on the slip-off-slope, the river moves. It covers a large area over time as it moves and 'smooths out' the land.
Dynamic equilibrium occurs at the point where the erosion and deposition of sediment are balanced, typically found in the middle or thalweg of a straight channel of a stream. At this location, the stream is in a state of dynamic equilibrium where the overall shape and characteristics of the channel remain relatively stable over time.
