E.1.1 General mathematical model
The flow of water in the watertable of homogeneous isotropic soil is governed by Darcy's law:
where v is the effective velocity of water flow, K is the constant hydraulic conductivity, h is the hydraulic head.
The hydraulic head at any given point is
where z is the gravitational head, i.e. the vertical height above the origin of coordinates, and p is the pressure head.
In this appendix only steady flows will be considered, i.e. flows where ...
