Because as the river slows it deposits more than when it flows fast.
Because the Width and Depth both increase downstream. This means the wetted perimeter will also increase.
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.
Silt
silt
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.
yes because of the yellow silt it carries downstream
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.
Rivers carry silt downstream and build deltas.
Rivers carry silt downstream and build deltas.
The the bearing capacity of silt soil can be improved by:Compacting the soil to increase it's density.Increasing the depth of the foundation layer as the increased effective stress will act to increase bearing capacityThe use of geosynthetics may act to increase bearing capacityThe use of lime stabilisation / soil mixing techniques may also act to increase the bearing capacity of silt.
The very old winding brook became filled with silt, and no longer flowed as strongly as it once had.
Fine silt and mud are carried further downstream than heavier rocks and gravel. Which often results in muddy banks at the river mouth.
