SHE model blind evaluation tests for Slapton Wood catchment, Devon, UK (1/1/90-31/3/91):
(a) comparison of the predicted phreatic surface level bounds for square (14; 20) with the measured levels
for dipwell (14; 18); (b) comparison of the predicted bounds and measured weekly soil water potentials at
square (10; 14) for 1.0m depth (after Bathurst et al., 2004, with kind permission of Elsevier).
The resulting uncertainty bounds on the model predictions were declared successful in predicting both
water table levels and soil water potentials (Figure 5.7). The authors note that the bounds could have been
set much wider if the only aim had been to bracket the observations. The model was also successful in
predicting the total volumes of discharge outputs from the catchment (although the bounds were of the
