MODFLOW-USG

TRRP Training: 2022 Program

presented by: GSI Environmetal Inc.

Texas Risk Reduction Program regulations (TRRP; 30 TAC 350) establish consistent risk-based protocols for assessment and response to soil, groundwater, or surface water impacts associated with environmental releases of regulated wastes or substances.

Presented by GSI Environmental Inc., this popular and informative training series is a must for professionals who need a working understanding of TRRP and those needing to stay up-to-date with the latest TCEQ TRRP guidance and policies.

TRRP Training Course (2 Days): Provides an overview of the TRRP framework and step-by-step training on property assessment and response action procedures established under the TRRP rule

Attendees will become acquainted with rules, key guidance and policies covering affected property assessments, protective concentration levels, and response actions. The course material presents strategies for efficient project management in compliance with TRRP and explains the various report forms adopted by TCEQ.

MODFLOW-USG solves the groundwater flow equation using unstructured grids. Many advanced packages are included to solve practical water resource problems.

An unstructured grid version of MODFLOW called MODFLOW-USG has been released by the USGS to provide flexibility in gridding for MODFLOW solutions. Sorab Panday, Principal at GSI, is a lead developer of MODFLOW-USG and worked closely with the USGS on its development.

Unstructured grids allow for inclusion of various cell geometries and grid-nesting methodologies to discretize the domain as well as inclusion of various other flow processes and domains such as flow through interconnected one-dimensional features like fractures, karst, wells, or channels in a fully implicit formulation using the “Connected Linear Network” (CLN) Package. The code is in the public domain and is freely available from the USGS website.

Further development of MODFLOW-USG has continued with additional enhancements and features including the following highlights:

Multi-species contaminant and heat transport
Agricultural or remedial system return flow package (QRT) with solutes
Density dependent flow and transport
Unsaturated zone flow (Richards Equation) and transport
Dual-porosity flow and transport

Matrix diffusion
Time varying material properties
Automated time stepping
Turbulent flow through conduits
Several user-friendly mechanisms to restart or continue simulations and simplify processing

These features are available through the USG-Transport software available as open source and public domain. Click here to obtain the source code, executable, and documentation.
