Abstract

A QUASI THREE-DIMENSIONAL FINITE ELEMENT MODEL IS PRESENTEDFOR THE ANALYSIS OF GROUNDWATER FLOW AND LAND SUBSIDENCE DUE TO PUMPAGE IN MULTIAQUIFER SYSTEMS. IN THE MODEL, AQUIFERSARE SIMULATED WITH THE AID OF TWO-DIMENSIONAL HORIZONTAL FINITE ELEMENT GRIDS. EACH AQUIFER IS CONNECTED TO ITS NEIGHBORS ABOVE AND BELOW BY ONE-DIMENSIONAL VERTICAL FINITE ELEMENT STRINGS WHICH ALLOW LEAKAGE TO TAKE PLACE ACROSS AQUITARDSAND AQUICLUDES. LAND SUBSIDENCE IS MODELED BY VARYING THE VOID RATIO OF EACH VERTICAL ELEMENT ACCORDING TO A NONLINEAR VERSION OF TERZAGHI'S ONE-DIMENSIONAL CONSOLIDATION THEORY.
