Transmissivity in Groundwater Hydrology Formulas

The Transmissivity refers to the measure of how much water can be transmitted horizontally through an aquifer is the product of the hydraulic conductivity of the aquifer and its saturated thickness. And is denoted by τ. Transmissivity is usually measured using the Square Meter per Second for Kinematic Viscosity. Note that the value of Transmissivity is always positive.

FAQ

What is the Transmissivity?

The Transmissivity refers to the measure of how much water can be transmitted horizontally through an aquifer is the product of the hydraulic conductivity of the aquifer and its saturated thickness. Transmissivity is usually measured using the Square Meter per Second for Kinematic Viscosity. Note that the value of Transmissivity is always positive.

Can the Transmissivity be negative?

No, the Transmissivity, measured in Kinematic Viscosity cannot be negative.

What unit is used to measure Transmissivity?

Transmissivity is usually measured using the Square Meter per Second[m²/s] for Kinematic Viscosity. Square Meter per Hour[m²/s], Square Centimeter per Second[m²/s], Square Millimeter per Second[m²/s] are the few other units in which Transmissivity can be measured.
