   Leaky (Semi-Confined) Aquifers
   These formations are bounded by an aquitard—a layer that is relatively impermeable but permits slow vertical leakage of water. The rate of leakage is determined by the hydraulic conductivity of the aquitard, which is frequently modeled using the specific impedance factor, $\Omega_i$, where:
   $$ \Omegai = \frac{Ka La}{Kw b_w} $$
   Where $Ka$ is the conductivity of the aquitard, $La$ is …
