Summary
Hypothetical two-dimensional, steady-state groundwater flow models of a previously published 1988 model calibration exercise were developed using the finite-difference computer code, MODFLOW-2005, to demonstrate the power of modern parameter estimation and uncertainty approaches. For this study, an initial run recreated the 1988 "truth" model. The true model was then simplified to account for information not provided the participants in the 1988 calibration exercise. Increasing sophistication was brought to bear to demonstrate how problems identified in 1988 were overcome using modern software approaches. This USGS data release contains all of the input and output to run the model simulations described in the associated journal article [...]
Summary
Hypothetical two-dimensional, steady-state groundwater flow models of a previously published 1988 model calibration exercise were developed using the finite-difference computer code, MODFLOW-2005, to demonstrate the power of modern parameter estimation and uncertainty approaches. For this study, an initial run recreated the 1988 "truth" model. The true model was then simplified to account for information not provided the participants in the 1988 calibration exercise. Increasing sophistication was brought to bear to demonstrate how problems identified in 1988 were overcome using modern software approaches. This USGS data release contains all of the input and output to run the model simulations described in the associated journal article (https://doi.org/10.1111/gwat.12907).
The purpose of the groundwater flow modeling was to demonstrate how modern calibration and uncertainty analysis software can overcome common problems associated with making forecasts with groundwater models. The purpose of the scenarios involving increasingly sophisticated methods was to educate the reader about the tools as well as the modeling problem solved. Explanation of models included in this data release are documented in the article published by the journal Groundwater (Wiley Publishing) (https://doi.org/10.1111/gwat.12907).
