Notes
This map relates hydraulic head, \(h\), in m to the volumetric current density, \(q\), (A/m^3) using a cross coupling term to convert the negative gradient of hydrualic head into secondary current densities. This cross coupling parameter \(L\) is a multiplication of the hydraulic conductivity (m/s) of the material and the ionic density (C/m^3) of the fluid.
The mapping is:
\[q = \nabla \cdot L \nabla h\]
