The outer boundary condition is set as Dirichlet with a hydrostatic pressure along the shell surface of the slice equivalent to a head of $h = 0 m$ (i.e. water level equals top of domain). For mass transport, a Dirichlet boundary conditions with concentration $c = 0$ is set at the outer shell. The inner boundary condition is equivalent to the eighth of a total abstraction rate of $Q_t = 15 m^3/d$ for a full cylinder. *NB: In the `ComponentTransport` process, the Neumann BC is given as mass flux and has to be calculated per area, such that the value for the project file is $Q = Q_t / 8 / A \cdot \rho = 2.83542E-03 m^3/s/m^2 \cdot kg/m^3$ with fluid density $\rho = 1000 kg/m^3$ and abstraction area $A = 7.65 m^2$.*

The homogeneous, isotropic domain is defined for the radius $1 < r < 100 m$ and a thickness $b = 10 m$. Saturated intrinsic permeability is $\kappa = 7.6453E-13 m^2$ yielding a transmissivity of $T = 7.5E-05 m^2/s$; porosity is $\phi = 0.2$; specific storage is $S_s = 1.0E-03$ and defined through compressibility $\gamma = 5.0968E-08 s^2/m/kg$ (input tag fluid_density_pressure_difference_ratio is $\frac{\partial \rho}{\partial p} = \frac{S_s}{b \phi g \rho}$ with gravitational acceleration $g = 9.81 m^2/s$).

Mass transport properties are irrelevant as no transport processes are calculated.
