Numerical groundwater modeling is a strength of the USGS, from software development (likeMODFLOW) to applications, such as the regional groundwater availability studies highlighted in the December 2015 News and Highlights.
Numerical models are our most powerful tools for decision making. But these models require expertise to operate and require significant computational resources. Natural resource managers need reliable models to predict surface water impacts dues to installation of new groundwater wells and may not have the expertise or computer resources to run the necessary simulations. An alternative is to emulate the numerical process model with a statistical “metamodel”, or surrogate model.
This new paperillustrates the use of a metamodel in the aquifers within the Lake Michigan basin, a temperate region where shallow groundwater is closely connected with lakes, wetlands, and streams. A groundwater flow model was emulated using three statistical techniques -- a Bayesian Network, an Artificial neural network, and a Gradient Boosted Regression Tree. A numerical MODFLOW-USG model was used for the evaluation.
If you’re a member of the NGWA Scientists and Engineers Section, you will soon receive the Groundwater January-February 2018 issue. Below is a brief overview of what you will find.
In his Guest Editorial, Dylan J. Irvine encourages authors in Groundwater to share data, scripts, and spreadsheets with their readers to increase the impact of new methods and approaches. He argues this can much enhance the uptake of new complex methods, as readers do not have to determine how to implement these methods themselves...
If you are a member of the NGWA Scientists and Engineers membership section, you just received, or will soon receive, the May-June 2017 issue of Groundwater®. Below I offer a brief overview of the issue.
In his Guest Editorial, "The Ying and Yang of Groundwater," new Technology Editor David Lipson, Ph.D., offers his personal perspective of how theory and practice (modeling and fieldwork) in groundwater hydrology go hand in hand; one cannot do one without the other.
Lipson, who became technology editor in...
