Water moves on a slope by gravity. However, the Romans, discovered that if the slope was only 2o ( two degrees) from the horizontal, then the water would flow , without surging. To this end they built their aqueducts with this slope, so no machinery was required to make the water flow. To lift water to a greater height, they used the Archimedean Screw., which was moved by a donkey/mule chasing a carrot around a rotating pole.
Hydraulic gradient
The type of water erosion that forms larger channels down a steep slope is called gully erosion. Gully and rill erosion are the dominant types of water erosion in the world.
For water the line has a negative slope (vs carbon dioxide). This explains why ice floats since volume decreases with increasing pressure as we move upward on the phase diagram from solid to liquid water, the volume occupied by H20 decreases and thus water must be increasing in density.
then the slope is x=y. there is no slope.
