Groundwater flow simulation using MODFLOW Bangkok : Asian Institute of Technology, 1991 77, A-2, B-18, C-10 p. Thesis ; no. WA-91-9 A thesis submitted in partial fulfillment of the requirements for the Master of Engineering, School of Engineering and Technology Thesis (M.Eng.) - Asian Institute of Technology, 1991 Heavy pumping of groundwater in Bangkok aquifers in past decades has created many undesirable effects and the complex nature of Bangkok aquifer system requires 3-D representation. In this study a versatile and portable 3-D groundwater flow model, MODFLOW has been adapted to simulate complex Bangkok multi-aquifer system. MODFLOW performance for Bangkok multi-aquifer system was first verified by using the same parameters and discretization used in a previous quasi 3-D model and comparing with the quasi 3-D model results. Hydrogeologic parameters were reevaluated from the detailed stratigraphic sections and calibration was performed to obtain an improved set of model parameters. The simulation period was extended from 1986 to 1990 with field data provided by Department of Mineral Resources. Finally MOD FLOW was used to predict the future performance of Bangkok multi-aquifer system. MODFLOW performance with the improved parameters is much better than that of quasi 3-D model and its parameters. Hydrogeologic parameters obtained in calibration with MOD FLOW agree very closely to field estimation.
