Process Section -- CAP Block Descriptor -- 5-Year Proof of concept Monitoring A 5-year proof of concept monitoring network will be developed in accordance with the CAP. This phase of monitoring will use groundwater wells in a monitoring network to determine if the monitoring network design will provide adequate CAU surveillance. Measurements of field parameters will be used to demonstrate that the model is capable of making reasonable predictions that fall within an acceptable level of confidence. Model validation, to ensure fidelity of the model to the physical system, will utilize a ten-step protocol to demonstrate that a model has been developed which meets user needs. These ten steps are: 1) Establishment of model purpose, 2) Development of conceptual model, 3) Selection of a computer code and verification of code, 4) Model design, 5) Model calibration, 6) Sensitivity and uncertainty analyses, 7) Model verification, 8) Predictive simulations, 9) Presentation of model results, and 10) Postaudit. The validation postaudit step tests whether the model can predict future system behavior. The five-year proof of concept is the model postaudit to establish, within a longer time frame, that the model is capable of producing meaningful results with an acceptable degree of uncertainty. Model validation is substantiated once all ten steps are shown to have been acceptably completed. |
