Abstract: Solutions are presented for the effect of pumping of groundwater on the settlement of the ground surface. These solutions cover the cases of pumping from a point sink in homogeneous, non-homogeneous, isotropiic and transversely isotropic, soil deposits. In all cases it is assumed that the soil skeleton is elastic, pore fluid flow obeys Darcy's law and that the water table always remains at the ground surface. These solutions should allow predictions to be made of time dependent and long term (steady state) settlements for many practical problems involving groundwater pumping. Les solutions sont presente pour l'effet de l' extraction de l'eau sur les tasse- ments de la surface des sols. Ces solutions ont obtenu pour le cas ou l'eau est pompe d'un point dans un sol qui est homogene, non-homogene, isotropie ou transversalement isotropie. Pour tous les exemples on assume que le sol est dlastique, que le cours de l'eau obeit la loi de Darcy, et que la table de l'eau est toujours a la surface du sol. Ces solutions permettent la prediction de la variation des tassements avec le temp et aussi les tassements finals pour beaucoup des problemes pratiques.
