What is critical hydraulic gradient?
The critical hydraulic gradient is the threshold at which soil begins to experience internal erosion or piping due to water flow. It represents the maximum hydraulic gradient that can be sustained without causing soil particles to be dislodged and transported. When the hydraulic gradient exceeds this critical value, it can lead to instability and failure of soil structures, such as embankments or dams. Understanding this concept is essential for geotechnical engineering and the design of safe infrastructure.
What is hydraulic gradient?
It is ratio of height to length ie., h/L.
What is a relation between permeability and hydraulic conductivity?
Permeability is a measure of a material's ability to transmit fluids through its pore spaces, while hydraulic conductivity quantifies how easily water can flow through a material under a hydraulic gradient. Hydraulic conductivity is influenced by both the permeability of the material and the properties of the fluid, such as viscosity and density. Essentially, hydraulic conductivity is a practical application of permeability, particularly in the context of groundwater flow and engineering.
What was the advantage of using hydraulic mining when mining for gold?
Hydraulic mining blasts away the surface of the mine with highly pressurized jets of water. This allows for easy access to the minerals underneath. A negative consequence of Hydraulic mining is the damage to the surrounding environment.
Is hydraulic fluid and hydraulic oil the same thing?
Hydraulic oil and hydraulic fluid are different. Hydraulic fluid is used in small systems such as car brakes. Hydraulic oil is used in large systems such as loaders.

The steepness of a water table's slope is know as its?
Hydraulic gradient
What does a positive and a negative gradient look like?
A positive gradient goes uphill from left to right A negative gradient goes downhill from left to right
What is hydraulic gradient?
It is ratio of height to length ie., h/L.
How do you calculate factor of safety against quick condition?
FS= critical hydraulic gradient/exist hydraulic gradient icr=(saturated unit wt - water unit wt)/water unit wt
What is the negative reciprocal of a slope?
The negative reciprocal of any gradient gives the gradient of the line perpendicular to it. If you had a line of gradient 2, the negative reciprocal would be -1/2 Just change the sign on the number and flip the number/fraction to get the negative reciprocal.
When either the run or rise are negative the line is?
one with a negative gradient.
Why do you measure the gradient of a river in negative numbers?
Well, we could speculate. We do notice that from any point, the river always flows in the direction of the negative gradient ... that is, the direction of the greatest negative slope.
Will the gradient of y equals -x plus 1 be positive or negative?
negative
What controls the rate of movement of ground water?
The porosity and permeability of the soil or rock control the rate of movement of groundwater. Other factors such as hydraulic gradient, hydraulic conductivity, and gradient also influence the speed at which groundwater moves through the subsurface.
What is meant by negative gradient of a quantity?
The gradient of a quantity is the greatest rate at which it changes as you move in different directions from where you are now. If the quantity has a negative gradient, that means that the quantity decreases in that direction. A great example of a negative gradient is the elevation of the land at a point on a road that has a hill on one side and a cliff on the other side. The greatest rate at which the elevation changes is in the direction off the edge of the cliff, and it's negative in that direction.
Does the line of best fit have to have a positive gradient?
Not at all. If the two variables have a negative correlation, that is as on increases the other decreases, then the line of best fit would have a negative gradient.
