Hydraulic gradient: In general, the direction of groundwater flow due to changes in the depth of the water table.
Hydrocarbon: Organic compounds that are built of carbon and hydrogen atoms and are often used in petroleum industries.
Hydraulic Gradient (i): Slope of a water table or potentiometric surface. Groundwater flows from points of high elevation and pressure to points of low elevation and pressure.
HYDRAULIC GRADIENT
The change in hydraulic head (pressure) per unit distance in a given direction (dimensionless). It is the driving force of fluid flow in a porous medium.
hydrocarbons ...
hydraulic gradient The slope of the hydraulic grade line. In open channel flow, it is the slope of the water surface. In pipes under pressure, it is the slope of the water pressure.
hydraulic gradient. The slope of the hydraulic grade line
This is the slope of the water surface in an open channel,
the slope of the water surface of the groundwater table, or ...
Hydraulic Gradient (i, dH/dX)
The gradient or slope of the water table, or of the potentiometric surface, in the direction of the greatest slope, generally expressed in feet per mile.
Hydrocarbons (HC) ...
Hydraulic Gradient
The slope of the water table or aquifer. The hydraulic gradient influences the direction and rate of groundwater flow.
Hydrologic Cycle ...
Hydraulic Gradient: The slope of the groundwater level or water table.
Hydraulic Head: Height above a datum plane (such as mean sea level) of the column of water that can be supported by the hydraulic pressure at a given point in a groundwater system.
hydraulic conductivity A measure of the rate at which water can move through a permeable medium if the hydraulic gradient of the ground-water flow system is unity (45 degrees).
The downward movement of water through soil; specifically, the downward flow of water in saturated or nearly saturated soil at hydraulic gradients of 1.0 or less.
periglacial ...
Aquitard: 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.
