MARUN
model is the short for Marine Unsaturated

Model formulation
In the absence of source/sink terms, the equation for the conservation of the fluid mass (water + salt) is: $$ \frac{\partial\left(\beta \phi S\right)}{\partial t*} = \frac{\partial\left(\beta \delta K_x* \frac{\partial \psi *}{\partial x*} \right)}{\partial x*} + \frac{\partial\left(\beta \delta K_z* \frac{\partial \psi *}{\partial z*} \right)}{\partial z*} + \frac{\partial\left({\beta}^2 K_z* \right)}{\partial z*} $$ where $$ \phi \left[ - \right] $$ is the porosity of the medium and S is the water saturation ratio of soil moisture with a value of 1 implying fully saturated soil,

In the absence of source/sink terms, the equation for the conservation of the solute equation is expressed as: $$ \frac{\partial \left( \phi S c* \right)}{\partial t*} = $$
