Infinite Extent Help

Huisman Assumptions

From:

Kruseman, G. P., and de Ridder, N. A.1991. Analysis and Evaluation of Pumping Test Data, Second Edition, International Institute for Land Reclamation and Improvement, Wageningen, The Netherlands.

• The aquifer is confined.
• The aquifer has a seemingly infinite areal extent.
• The aquifer is homogeneous, isotropic, and of uniform thickness over the area influenced by the test.
• Prior to pumping, the piezometric surface is horizontal (or nearly so) over the area that will be influenced by the test.
• The aquifer is pumped at a constant discharge rate.
• The flow to the well is in steady state.
• The aquifer is not fully penetrated by the well.
