Abstract: The Laplace equation was solved analytically in two dimensional homogeneous, isotropic ground water flow fields for different water table configurations with the aid of least square method. The flow pattern for different shapes of water table configuration was obtained from a mathematical model and the following results were obtained: For the water table configurations which have central symmetry relative to the point obtained from the intersection of the water table curve and the mid-line, no matter what is the slope, the transition point from recharge to discharge is halfway between the water divide and the valley bottom. For several water table configurations other than those mentioned above, the transition point from discharge to recharge zone is not half-way between the water divide and valley bottom, but rather tends to occur closer to the lowest elevation. In this group of study, more elaboration is needed for drawing a general conclusion.
