A visco-elastic analytical model is presented for the simulation of large scale groundwater flow and land subsidence. Groundwater flow is simulated by a two-dimensional flow model. Land subsidence is modeled vertically by using the Taylor-Merchant one dimensional consolidation theory. In application, multiple aquifers are generalized by using a field approach based on a few 'bulk parameters', which allows the direct use of records obtainable in situ. / The visco-elastic model is applied to analyze and predict the land subsidence in Bangkok, Thailand. The results demonstrate that the visco-elastic model can yield a satisfactory prediction of consolidation that is better than that obtained with the classical Theis-Jacob approach. / Predictions of the piezometric head and subsidence for the 20 years from 1981-2000 were made based on the following three scenarios: (1) a constant withdrawal at 1980's rate, (2) a cessation of all pumping wells, and (3) simultaneous pumping and injection, with injection exceeding 1980's pumping rate by 50%.
