A rocky stream bed with large, irregularly shaped rocks would cause the most friction for water flowing over it. The rough surface of the rocks creates turbulence and resistance, slowing down the water flow.
A rough and uneven streambed would cause the most friction. Large rocks, boulders, or other obstacles in the streambed create turbulence and resistance to the flow of water, increasing friction. Smooth and flat streambeds, on the other hand, have less friction as water can flow more freely over them.
Friction does not move things. Friction is the force that opposes motion between two objects that are touching. Not enough friction allows for things to move, depending on what kind of friction; the less force it has.
When solid surfaces slide over each other, the kind of friction that occurs is called sliding friction. This type of friction results from the resistance to motion between the two surfaces in contact.
Static friction is the type of friction that acts on objects that are not moving. It occurs when two surfaces are in contact but not sliding past each other.
There are many applications that would benefit from less friction. Any kind of motion where heat is produced but not intended would benefit from less friction. Some examples: 1. the contact point between the piston and wall in an engine produces less heat and more power with less friction 2. air flow over a car's exterior, over a plane's exterior, over a rockets exterior results in reduced drag (air resistance) with less friction 3. the space shuttle could definitely use less friction with the atmosphere during re-rentry 4. electrical conductors are more efficient as friction decreases 5. if friction were 0, the perpetual motion machine would be possible

I think you are talking about a groove cast. Groove casts form in the bottom of a stream when transported sediment is dragged along a mud bottom.
This kind of friction is referred to as drag, or air resistance.
The kind of force you will need to use a 550g box is a push and a pull and also that is when friction comes in too because it is just not about the forces because friction is based on force's the kind of friction that will come in is the sliding friction,rubbing friction,and static friction reason is because when a box is that heavy you just cant pick it up there has to be some kind of friction that comes into play so there will be some sliding across the ground and so rubbing also.Also fluid comes in when involved with water and other things
