The Network for Engineering With Nature® (N-EWN) invites you to the “N-EWN Knowledge Series: A Continuing Education Series about Engineering with Nature—Modern, reproducible modeling workflows for water feature design,” presented by Dr. Anthony Aufdenkampe, senior environmental scientist of LimnoTech. This 1-hour Zoom webinar will take place April 16, at 12:30 p.m. ET.

Nature-based solutions (NBS) to improve water quality all strive to leverage natural ecological and biogeochemical processes. The interplay among these processes, especially in the context of moving water, can be challenging to anticipate. When high confidence in predicted NBS outcomes is critical, project owners and stakeholders commonly request numerical modeling. Unfortunately, most existing water simulation tools were built decades ago on empirical relationships rather than process-based simulations. Federal agencies have recognized this gap (see NOAA Modeling Strategic Plan for 2024-2033) and the critical need to modernize the process-based models that
do exist and to develop reproducible workflows to setup, run, and analyze coupled models.

This webinar will present this federal vision for reproducible, process-based modeling workflows and describe LimnoTech’s related work with ERDC, USGS, and others. These include: (A) developing the new ClearWater (Corps Library for Environmental Analysis and Restoration of Watersheds) modeling system; (B) contributing and applying the MF6RTM package to couple Modflow6 groundwater transport with PHREEQC geochemical reaction models for contaminant mobility for Aquifer Storage and Recovery (ASR) planning; and (C) assessing various design scenarios for biofiltration of constructed lakes using the General Lake Model with Aquatic Ecosystem Dynamics (GLM-AED) libraries.
