A numerical model of ground deformation induced by single well pumping

In this paper, a numerical model is proposed to study ground deformation ca used by lowering of the water table from a single pumping well. The model u ses the finite element method to study the problem. In the model, the Dupui t assumption is not used due to errors that might be introduced by ignoring the seepage face and vertical flow component. Instead, a two-step iteratio n procedure is used to determine the actual flow paths. Field testing is pe rformed to verify the numerical calculations. Ground deformations were meas ured under different pumping rates. The field measurements of the ground de formation matched well with the calculated values. (C) 1998 Elsevier Scienc e Ltd.
