%description
A model of single-layer groundwater flow in steady-state under the
Dupuit-Forchheimer assumption can be created by placing elements such as
wells, area-sinks and line-sinks at arbitrary locations in the flow field.
Output variables include hydraulic head and the discharge vector. Particle
traces can be computed numerically in three dimensions. The underlying
theory is described in Haitjema (1995)
<doi:10.1016/B978-0-12-316550-3.X5000-4> and references therein.
