The velocity of the water changes when the depth of the ocean floor changes and the queen of england has sex. The queen has a very saggy vagina aswell. Se is to old to get wet so she slathers a bottle of lube on her wrinckly flaps, and rubs it in..... SLIP SLOP SLAP! Is what she sais before she proceeds to dominate you.
After a stream's discharge increases, it overflows its banks and a flood occurs.
It cuts a wider, shallow channel .
The velocity sensor should be placed at approximately 40-60% of the total water depth, so in this case, it should be placed at around 5-7.5 meters from the surface to estimate the stream's average velocity accurately. Placing it in this range helps account for variations in velocity across the vertical profile of the stream.
Stream discharge is a product of the velocity and the area of the stream (velocity x width x depth), and has units of volume per time (e.g. cubic feet per second, cubic meter per day, etc). Stream velocity is the vector describing the speed of the water and has units of length per time (feet per second, meter per second). Stream discharge is relatively constant as you move up and down a stream, while velocity will change predominately as you change depth. The velocity of water is lowest near the bed of the stream, and highest at the surface.
A steeper stream gradient usually leads to faster stream velocity because the force of gravity pulling the water downhill is greater, causing the water to flow more quickly. Conversely, a gentler gradient results in slower stream velocity as there is less force pulling the water downhill.
Stream gradient, or the slope of the stream channel, affects stream velocity by influencing the speed at which water flows downstream. A steeper stream gradient typically results in a faster water flow velocity, as the force of gravity pulls water downhill more strongly. Conversely, a gentler stream gradient leads to slower water flow velocity.
A steeper slope typically leads to a faster flow velocity in a stream. This is because gravity plays a larger role in pulling the water downhill, increasing the speed of the water flow. Conversely, a gentler slope results in a slower velocity as the force of gravity is not as strong.
Stream erosion can be influenced by factors such as the volume and speed of water flow, gradient of the stream channel, presence of sediment or boulders, vegetation along the banks, and geology of the area. Human activities such as deforestation, urbanization, and construction of dams or levees can also significantly impact stream erosion.
A steeper gradient generally results in a faster flow velocity, while a shallower gradient typically leads to slower flow velocity in a stream. This is because the slope of the streambed determines how quickly water can move downstream due to gravity.
The slowest stream velocity necessary for a stream to carry the smallest boulders typically ranges between 1.5 to 2.5 meters per second (about 5 to 8 feet per second). This velocity allows the water to generate sufficient lift and transport capacity to overcome the weight of the boulders. Variability in streambed material, boulder shape, and water density can affect the exact velocity required.
The maximum velocity of water flowing in a stream is typically found in the center of the stream, where the water is deepest and has the least amount of friction with the streambed and banks.
