on groundwater modelling

J. Bredehoeft (2010) in Models and model analysis writes:

We collect all the available geologic data and create cross sections and isopach maps of various hydrostratigraphic layers. We decide that the geologic information is incomplete, and drill additional test wells. By this time, the project is 75% to 80% complete, and now we build "the groundwater model". We run the model, and we find it is sensitive to data that we failed to collect (e.g., the vertical hydraulic conductivity of a confining layer). Perhaps even our concept of the system is invalid. But there is neither time nor money left in the project budget—the model informs us that we need another project.
