摘要

Any philosophy that in its quest for certainty ignores the reality of the uncertain in the ongoing processes of nature denies the conditions out of which it arises.-John Dewey, The Quest for Certainty, 1929 With great power comes great responsibility.-Voltaire Today's groundwater modeling tools are characterized by power, capability, and sophistication that was unthinkable even a few years ago. Boundary conditions (lakes, streams, wetlands) have advanced modules that allow more realistic depictions of the natural world. Models can simulate multiple scales conjunctively (Mehl and Hill 2005; Hunt 2006), or combine different formulations of the underlying mathematical governing equations (Haitjema et al. 2010). The unsaturated zone can be rigorously included (Jones and Woodward 2001; Radcliffe and Simunek 2010), even on a large watershed scale using kinematic wave approximations (Niswonger et al. 2006).
