Two views of the cone of depression around a pumping well, for a constant pumping rate and a laterally extensive isotropic and homogeneous confined aquifer (calculated using the Theis equation), with a flat water table or piezometric surface. Pumping rate, aquifer parameters, and duration of pumping are the same as in the No-Flow Boundary and Constant-Head Boundary cases.
You can also download a MicroSoft Excel (v. 4) Chart of this well, allowing you to rotate and view the image from other directions (configure your Web Browser to recognize MIME type "application/excel," using MicroSoft Excel as the "helper" application).
