Gravel doesn't fit close together like clay soil particles do, slowing down water flow through mud. If you visualize gravel as a screen of 1/8th inch mesh and clay soil as a screen of 1/128th mesh ( 16 times smaller holes ) you can then easily understand that water flows very swiftly through the gravel screen compared to the fine particles of clay soils.
Low permeability and Steep slope
An aquitard is an impermeable lump of rock or clay. It does not allow water to flow through it which means that it blocks the water sending it to another destination.
Erosion is a fast process because the flow of water is fast by the additon of wind
If you are talking about science, then an aquitard is an impervious layer of clay, silt, or rock that will not allow the water to pass through it fast enough to be used as a water supply.Geological formation that may contain groundwater but is not capable of transmitting significant quantities of it under normal hydraulic gradients. May function as confining bed.
Canyons don't flow. Do you mean the river flowing through the canyon?
Sand. The sand has space between all of the little grains, clay is stuck together with less space.
it all depend on the person and there health but yes water does flow as fast as blood.
fast

No. Clay particles are very small and tend to attract other clay particles to from a matrix. Permeability refers to the ability of a gas or liquid to flow through a material. Because clay forms a tight matrix, gas and liquids flow very slowly through clay. Loose sand has high permeability
through flow is when infiltrated water moves through soil to the sea.
Normally the flow of water through a course grained material will be faster than through a fine grained material as the pore spaces between the grains tend to be larger.
Gravity causes water to flow downwards. In porous ground the water will seep into the soil. If the water hits a non-porous layer (clay, for instance) the water will spread horizontally.
Low permeability and Steep slope
Permeability is a measure of how fast water will flow through connected openings in soil or rock
It is a fast flow of water
