No, a river only flows one way, they either flow upstream or downstream not both.
Downstream. The source of a river is always upstream.
Upstream is where the flow is coming FROM . -Downstream is the direction it is going to.
The upstream of a river is its mouth, AKA, the opening to the ocean, and everything in between. Downstream is the source, AKA the "beginning", such as a lake, and everything in between.To put it simply:A RIVER:(Mouth)=--------------------------------------------------------------------------------0 (Lake) Downstream
downstream and upstream
You are going with the flow of the river
If the boat is moving downstream, you add the speed of the boat with the speed of the river flow. Therefore, the velocity of the boat downstream is 18 km/h. If the boat is moving upstream, you subtract the river flow speed from the boat's speed, so in this case, it would be 12 km/h.
assembly upstream and downstream in ammetres
it slows down because first it rushes down from mountain and then slows down right at the end when it goes into the sea/ocean/lake.
Downstream
upstream
Upstream and downstream systems are business terms that apply to the production process. The search for and extraction of raw materials refers to upstream. When these materials are processed refers to the downstream.
The closer to th engine is upstream and the farther is downstream Before the cat upstream After the cat downstream.
