can be predicted. The model selected was able to predict depositions
only fairly well, considering that the locationused to test the model was
within the network of the samplers used to develop the model. Also the
time period- during which the model was tested was the same as the
period during which the model was developed. On the other hand, a
systematic sampling error seems to have entered into the comparison.
The fact that the model could be used to fit data at other times and at
other locations indicates that the model may be more widely applicable
‘than for the conditions for which it had been developed.
