For aquifer saturated thickness d, hydraulic conductivity K and transmissivity T, which relation holds?

$T=Kd$
$T=K/d$
$T=\sqrt{Kd}$
$K=\sqrt{Td}$

Show answer and explanation

Correct answer: (A) $T=Kd$

Explanation

Transmissivity integrates conductivity across saturated thickness. For a homogeneous aquifer,$T=\int_0^dK\,dz=Kd$,**A**. Units are(m/time)(m)=m²/time. The source calls K permeability;the stated relation uses hydraulic conductivity.
