What is discharge in geography?
Discharge is the volume of water passing a given point over a set of time. To calculate discharge you do: Mean velocity x cross sectional area Steeper slopes should lead to higher velocities because of the influence of gravity. Discharge normally increases downstream, as does width, depth and velocity.
Where did the soil in the Indus River valley receive its rich silt from?
The soil in the Indus River valley receives its rich silt from the annual flooding of the river. The Indus River carries sediment and nutrients downstream, depositing them on the surrounding land during floods. This process replenishes the soil and makes it fertile for agriculture.
What does riverbed mean?
A riverbed is the channel where a river flows, typically made of gravel, sand, and other sediments deposited by the river. It serves as the natural path for water to flow downstream, shaping the landscape over time.
Why does load particle size decrease downstream?
Load particle size decreases downstream due to the transport capacity of the river being higher further downstream, allowing larger particles to settle out and be deposited. Smaller particles are able to remain in suspension and be carried further downstream before settling. Additionally, erosion and weathering of larger particles can lead to their breakdown into smaller particles over time.
What toll is used to measure the velocity of a river?
A current meter is typically used to measure the velocity of a river. This device is placed in the water flow to measure the speed and direction of the current at various depths. The data collected helps in understanding the flow dynamics of the river.
Why does average velocity increase downstream?
Average velocity increases downstream because of the overall flow of the river. As the river moves in the downstream direction, the volume of water increases due to tributaries adding water along the way. This increase in water volume results in a higher average velocity as the same amount of water needs to flow through a larger channel.
Why does river velocity increase downstream?
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.
Why does the water depth increase downstream?
Water depth increases downstream due to a combination of factors such as the accumulation of flow from tributaries, reduced friction along the river bed, and the energy gradient of the river. As the river flows downstream, it gains more volume and velocity, resulting in higher water depth.
Why do rivers speed up even when the radiant decreases?
There is less friction from the bed and banks of the river downstream (where the gradiant decreases) so the velocity increases.
How does the gradient of a river affect its flow?
The gradient of a river is mostly flat or downhill which means that as the water flows it is affected by gravity. The steeper the gradient goes downhill, the more gravity will affect the water which will make the water flow faster (increases the velocity).
How do floods affect river velocity?
Increases it
A boat moves at a speed of 15 kmh in still water. The river it is traveling in flows at a rate of 3 kmh downstream. What is the velocity of the boat if it travels downstream What is the velocity of th?
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.
Does a stream's velocity increase or decrease downstream?
A stream's velocity typically increases downstream due to the accumulation of water volume and slope gradient. This leads to higher flow rates and faster-moving water.
Why does load vary downstream?
This is the amount of load a river can carry. Generally, the load quantity will increase with discharge and velocity because rivers of higher discharge and velocity have more energy so will be able to carry more load. Therefore, load quantity increases downstream. Also, small particles require less energy to be carried so as the load size decreases, quantity increases
Why does the volume of the river increase downstream?
A river increases in volume as more streams join the main flow in the lower reaches.
What is the relationship between velocity sediment size and river size?
As the steam velocity increases, the diameter of the sediments being transported increases.
What is the river thames width?
The river Thames increases in width the further downstream you go. See related link...
