The impact of soil AWC on the slope of a linear regression
model of annual ET as a function of climate predictors: (a) precipitation,
(b) R75, and (c) TAMJ. The slope of the ET–climate predictor
is plotted across a physically viable range of mean basin soil AWC
for each climate predictor and for each study basin: OR-CAS (left
column), CO-ROC (middle column), and CA-SIER (right column).
The slopes are normalized to facilitate inter-basin comparison.
