Abstract

The relationship between land subsidence and water level decline caused by groundwater withdrawal in Kerman province, Iran, due to pistachio farming has been investigated by many researchers since 1992. The scope of this work is to examine the previous subsidence and predict the future subsidence. A detailed mathematical model of the actual land subsidence in Kerman is constructed for analysis. This fully coupled finite element consolidation model simulates the subsidence and the continuous piezometric decline of the area. The simulation is comprised of a 3-D flow model for resulting water pressure distribution at each time step. There is good correspondence between the finite element analysis and the actual field data.
