Explanation:
the hydraulic gradient is: group of answer choices the permeability of the rock. the slope of the water table. the increase in temperature with depth. the rate of flow of groundwater.
Groundwater moves in the direction of maximum decreasing total head under the influence of the hydraulic gradient.
Explain about the hydraulic gradient?The change in water level per unit of distance along the direction of highest head drop is known as the hydraulic gradient (1), which is the slope of the water table or potentiometric surface.
If the gradient is negative, which means the hydraulic head is lower at depth, there is an indication of a downward flow component. The hydraulic head is higher at depth if the gradient is positive, on the other hand, which denotes an upward flow component. The gradient's size tells us a lot about its importance.
This vector depicts the flow direction of groundwater, with zero denoting "no flow" and negative values denoting flow along a dimension.

When the acceleration is zero or the speed is constant, instantaneous and average velocities can both be equal. This is because all instantaneous velocities will be equal in this situation.
Explain about the Actual velocity?After the control filter and display filter have been applied, the filtered value that remains is known as the Actual Velocity. The Actual Velocity (Unfiltered) status register provides the unfiltered value, and the Actual Velocity (Control) value provides the first filtered value.
To calculate the velocity, multiply the distance travelled by the time needed to traverse that distance, then add direction. If one's position doesn't change, their velocity is zero.
