Groundwater is indispensable to human society and ecological integrity, but remains difficult to work with because of the properties of underground environments. Naturally, there have been many attempts to model these under-ground mechanisms. The model of interest is MODFLOW 2005, developed by the United States Geographical Survey, which outputs numerical simulations of groundwater processes. Specifically, I worked with data from an example case of the unsaturated flow zone package, which aimed to describe water table depths as a function of mainly infiltration (water in at land surface) and evapotranspiration (water out). The data describes the Sagehen watershed: a roughly 27 square mile patch of land on the side of one of the Sierra Nevada’s mountains.
