Abstract This paper describes research being carried out on the development of the role of poroviscosity in determining land subsidence due to groundwater extraction. Poroviscosity incorporates early-time (so-called instantaneous), intermediate (so-called primary consolidation) and late time (creep or so-called secondary compression) into one unified theory of time dependent skeletal compression. It requires only one constant to be evaluated for one-dimensional behaviour and at any time exhibits a semilogarithmic stress/strain relationship. Poroviscous theory should accordingly provide an improved accuracy of land subsidence prediction results when saturated sedimentary basin sequences are depressurized.
