FIGURE 6.18 Sequence of restrictions along the passage from modeling intentions to a valid
model application. Subsequent restrictions narrow the sphere of model applicability. Only the
investigator's experience and skills can expand the range of valid model applications.
Finally, some restrictions arising from data availability for initial conditions,
boundary conditions, or internal parameter specification are discussed in some detail.
In summary, the solution accuracy should not exceed the range of the spatial-
temporal variability of the simulated variables, and a model can only adequately
simulate a particular process within specific temporal and spatial scales. Using the
