What is upstream and downstream in rivers?
The term upriver (or upstream) refers to the direction towards the source of the river, i.e. against the direction of flow. Likewise, the term downriver (or downstream) describes the direction towards the mouth of the river, in which the current flows.
Do currents flow upstream or downstream?
A significant number of river-reservoir systems all over the world have large diurnal variations in atmospheric heating rates and develop density currents in the downstream river/ reservoir due to colder denser flow releases from an upstream reservoir.
How upstream affects downstream?
Typical examples might include polluted discharge in an upstream catchment that makes water downstream unusable; withdrawal of large amounts of water for irrigation upstream, leaving less water available downstream; as well as widespread land use change upstream which affects water availability and sediment loads …
How do you determine upstream and downstream of a river?
Downstream means towards where the flow ends, at the opposite end of the waterway from the source. If you are boating from Kingston to Toronto, for example, you are heading upstream. If you are going from Kingston to Cornwall, you are travelling downstream.
What is downstream on a river?
The word downstream (which is one word instead of being two words; down stream) mainly means the direction that the water in a river flows. Downhill, towards the sea, or nearer to the mouth of the stream (where the river ends). In all three cases, downstream means towards the end of the process or flow.
What is upstream and downstream in flow?
If the flow of data goes toward the original source, that flow is upstream. If the flow of data goes away from the original source, that flow is downstream.
Do all rivers flow downstream?
Rivers tend to flow downstream, but sometimes they don’t. Sometimes they flow sideways and sometimes they flow upstream! On the other hand, rivers in lowland regions tend to flow slowly, because the slope of the land is much less steep.
What is a good downstream rate?
Downstream speeds can range from 56 kilobits per second (Kbps) for dial up to 50 megabits per second (Mbps) for the fastest fiber-optic network connections offered by some Internet service providers. The average DSL connection is from 1 to 10 Mbps. Cable modems average 10 to 20 Mbps.
What are downstream impacts?
relating to or happening at a later stage in a process. downstream effects/costs. Synonyms and related words. Late or too late.
What direction is upstream?
English Language Learners Definition of upstream : in the direction opposite to the flow in a stream, river, etc. : toward the source of a stream, river, etc.
How are upstream and downstream problems calculated?
Upstream and Downstream – Formula
- Upstream = (u−v) km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Downstream = (u+v)Km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Speed of Boat in Still Water = ½ (Downstream Speed + Upstream Speed)
How are upstream dams and downstream water allocations related?
For example, diversion of upstream water supplies for irrigation, water supply, flood control and hydroelectricity generation will interrupt the continuous downstream transfer of water and sediment which would otherwise take place.
What’s the difference between a boat upstream and a stream?
Stream – The moving water in a river is called a stream. Upstream – If the boat is flowing in the opposite direction to the stream, it is called upstream. In this case, the net speed of the boat is called the upstream speed Downstream – If the boat is flowing along the direction of the stream, it is called downstream.
What is the formula for upstream and downstream?
According to the formula, Speed of the stream = ½ (Downstream Speed – Upstream Speed) Speed of the stream = ½ (26-16) = ½ × 10 = 5 km/hr Q 4.
What happens when water is diverted to the upstream?
Water that is diverted upstream means less water downstream, and the result is that upstream activities benefit at the expense of downstream activities. Determining the optimal level of water diversion between upstream and downstream uses is therefore a critical issue.
