Modeling session at the Geological Society of American Annual meeting in Indianapolis, November 4-7, 2018

Please join us for the 130th Annual Meeting of the Geological Society of America in Indianapolis, Indiana on November 4-7, 2018. Please consider submitting an abstract to our GSA Session T100. "Applications and Advances in Groundwater Flow Modeling”.   This session will focus on a range of groundwater flow modeling topics, including investigations of water quantity and quality, advances in modeling technology and visualization, and integration of groundwater flow models with other scientific disciplines.   Abstracts are due by August 14 at 11:59 pm PDT and can be submitted here.

  Sincerely,   Daniel B. Abrams, Groundwater Flow Modeler, University of Illinois, dbabrams@illinois.edu, 217-244-1520.

  Daniel R. Hadley, Hydrogeologist, University of Illinois, drhadley@illinois.edu, 217-300-0402.

    T100. Applications and Advances in Groundwater Flow Modeling. Groundwater flow models are an essential tool for addressing a number of hydrogeological and societal issues. This includes: 1) short and long- term water supply on a local and regional scale, 2) investigation of the fate and transport of both point and nonpoint contaminant sources, and 3) the role that groundwater plays in an integrated system, including its interactions with surface water, atmospheric systems, ecological systems, and anthropogenic activities. In recent years, advances in modeling and computing have greatly increased the number of options available to modelers, not only in terms of the type of model code (finite-difference, finite-element, analytic element) but also the tools to interact with the models (graphical user interfaces, scripting via FloPy). As a result, larger and more complex models are possible, and the process of updating and archiving these models can be more readily streamlined and even automated via scripting. A number of new visualization options using GIS tools are also available to communicate complicated model results to the public in 2D, 3D, and animated formats. This session will focus on these recent advances in modeling and visualization techniques, while also highlighting applied modeling of at-risk water supplies and biological systems sensitive to changes in groundwater quantity or quality.



Strack offers short course on AEM, October 24-27, 2018, Nelson, Wisconsin

The short course will be focused on the use of elementary analytic solutions and models created with the Analytic Element Method for solving groundwater flow problems. The approach to solving groundwater problems, regardless of their complexity, is greatly enhanced in terms of both insight and efficiency by carrying out preliminary computations. Such computations may consist of relatively simple solutions amenable to implementation, either in inter-active computer programs such as MATLAB, or in dedicated analytic element computer programs such as SLAEM or MLAEM.

McLane Environmental offers new AEM tutorials & training

flexAEM System offers an easy introduction to groundwater modeling using analytic element software. The system consists of hands-on tutorials, courses, software tools, and “best practice” tips to introduce you to analytic element modeling at your own pace. flexAEM materials are designed to help experienced modelers add a fast and powerful new technique to their toolkit, or to help hydrogeologists and engineers make the calculations they need without the steep learning curve of complex modeling software.

AnAqSimEdu - new free educational version of AnAqSim (analytic aquifer simulator).

AnAqSimEdu was developed as a supplement to the 2nd edition of the textbook Groundwater Science, published by Elsevier. AnAqSimEdu simulates single-layer steady flow with confined, unconfined, and interface domains. Allows heterogeneity and anisotropy. Line boundaries include: head-specified, normal flux-specified, river, interdomain. Nice user interface. Available at this link:
