Partially penetrating well:
LINEAR SOURCE IN A CONFINED AQUIFER
Both pumping
well and observation well are partially penetrating. The length of
the pumping well screen is less than the aquifer thickness. The
aquifer is anisotropic on the vertical plane. Considered are
drawdowns in observation well and in piezometer (an openended
small diameter pipe, wherein water penetrates through its
bottom).
All equations
for the linear source are written for the aquifer isotropic on the
vertical plane. In case of anisotropic aquifer the following
substituting should be made:
Conceptual schemes
Aquifer of infinite extent and
thickness
Semiinfinite aquifer
Recharge boundary
Noflow boundary
Bounded aquifer
Recharge boundaries
Noflow boundaries
Combination of a recharge and a
noflow boundaries
