  • To determine the transmissivity of the soil, the engineers measured both the hydraulic conductivity and the thickness of the layer.

Examples

  • Since the transmissivity and yield of the underlying limestone strata are extremely high, and the canal is connected through underwater culverts to the rest of the canal system, drawdown of the water level in the canal or area groundwater was not a concern at the proposed dredge pumping rate.

  • The cubic relationship of fracture transmissivity implies that fractures that occupy only a small portion of the rock or soil mass may prove to be very efficient conductors of fluid.

  • Heterogeneous transmissivity field superimposed on fracture zones at the Swedish Hard Rock Laboratory (scale of block is one km).

    Academic text (1997)
  • Unevenness or irregularities in the fracture surface may form flow channels with power-law sensitivities of transmissivity to the fracture wall separations.

    Academic text (1997)
  • The transmissivity of the aquifer allows for efficient water flow, which is essential for nearby irrigation systems.

  • The study revealed that variations in transmissivity across the region significantly affected the water supply during dry seasons.

Morphology

transmissivity = transmissive (semi-transparent) = transmit + ive + ity

Morphologically regular (transmissive + '-ity'), but the specific hydrogeological definition (hydraulic conductivity × thickness) is a technical sense not deducible from the morphemes alone.

Etymology

The word transmissivity comes from trans- 'across' and mittere 'to send', the same root as transmit. In groundwater work, transmissivity describes how well an aquifer or underground rock 'sends' water across its thickness, which is why the term measures water flow.
