Abstract
A second order stochastic differential equation is used for modeling o f water-table elevation. The data were sampled at the Borden Aquifer a s a part of a tracer experiment. The purpose of the water-table data c ollection was to determine presence of a water flow. We argue that the water-table surface is a simple plane oscillating up and down in time according to an equation for a stochastic oscillator. We derive the m odel, estimate its parameters and provide arguments for goodness-of-fi t of the model.
