A river increases in volume as more streams join the main flow in the lower reaches.
yes
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.
The velocity of the river increases downstream due to the cumulative effect of gravity pulling the water downhill. As the river flows downstream, it collects water from tributaries and gains more volume, leading to an increase in velocity to accommodate the larger volume of water. Additionally, friction between the water and riverbed is reduced downstream, allowing the water to flow more freely and pick up speed.
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.
Depth and width of a river typically increase downstream due to several factors, including increased water volume from tributaries, reduced gradient, and erosion processes. As water flows downstream, it erodes the riverbanks and bed, widening and deepening the channel. Additionally, sediment transport and deposition can alter the river's shape, contributing to these increases in size. Overall, the combination of hydrological dynamics and geological processes leads to a broader and deeper river 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.
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.
Channel depth typically increases as you move downstream due to the accumulation of water volume and sediment load from upstream sources. As the flow progresses, the river or stream gains more energy, allowing it to erode deeper into the channel and carry a greater volume of water. Additionally, downstream channels tend to widen, which can also contribute to increased depth.
Because as the river slows it deposits more than when it flows fast.
Decrease. The source of the river is usually in a mountainous area with a steep gradient.
Downstream. The source of a river is always upstream.
