Last week Mundell & Associates employees participated in and presented at the Association of Environmental Engineers and Geologists 63rd annual meeting, held virtually this year.
Major topics of the conference this year included engineering geology for tunnels and underground construction; radon investigation and remediation; lessons learned for dams, levees, and naturally occurring asbestos; practical examples for applied geoscience methods for problem solving; and a landslide symposium.
John Mundell presented the work of Mundell & Associates on 2 projects during the “Dams and Levees Lessons Learned Symposium” on September 17 and 18th.
“Geophysical Evaluation of Dam Seepage to Support Rehabilitation Efforts” detailed the various Geophysical methods and outcomes during a project in Muhlenberg County, Kentucky. 2D Electrical Resistivity Imaging, Frequency Domain Electromagnetic Terrain Conductivity and SP Profiling, and Ground Penetrating Radar were used to understanding potential seepage pathways and selection of remedial alternative for the dam. Contributors to this project included John, Ryan Brumbaugh, and Forrest Kunkel.
On the following morning, John presented “Calibrating Artificial Intelligence and Hydrologic Modeling with Smart Monitoring Inputs for Enhanced Levee Safety Predictions under Changing Climate Conditions” of a levee project in Greendale, Indiana (contributors Tyler Balson, Luke Johnstone, and Forrest Kunkel).
This project used various data inputs (area-specific river gauging, area groundwater levels, precipitation, and drone photography) in the development of linear, hydrologic and machine learning models to simulate river and groundwater levels during high water events. Based on analysis of data from this project, machine learning techniques appear to be able to replicate predictions made from calibrated linear and hydrologic models based on real world physical relationships.
Although the conference was held virtually this year, participants enjoyed a packed schedule and the innovative opportunities for online networking, thanks to the hard work of all the organizers!
