A Simplified Model for the Transient Water Budget of a Shallow Unsaturated Zone

Abstract

A simplified model describing the transient water budget of a shallow unsaturated soil profile is presented and applied to an example of long-term climatic conditions for a site near Coshocton, Ohio. Drainage for a fifty year long record of climate on a daily basis for the Coshocton site compared well with measurements from four lysimeters. The model is useful to help determine the appropriate cumulative evapotranspiration consistent with site climatic data.
