Groundwater Modeling

Groundwater Supply and Sustainability

• Long-term basin-wide planning
• Development of groundwater supplies
• Groundwater sustainability assessment
• Incorporate climate projections and surface water availability assessments
• Seawater intrusion
• Typical codes include MODFLOW, MODFLOW-OWHM, GSFLOW, and IWFM

Managed Aquifer Recharge

• Feasibility assessment
• Projection of groundwater impacts from recharge operations
• Aquifer storage and recovery projects
• Assessment of travel times in support of indirect potable reuse

Environmental Remediation

• Determining capture zone of an extraction wellfield
• Evaluating risks of losing containment of a plume
• Assessing when a remedy needs to be expanded
• Determining remediation cost allocation
• Typical codes include MODFLOW, MT3D, USG-Transport, MODPATH, and modPATH3DU

Brine Resources

• Groundwater flow and transport modeling in support of lithium and potassium brine reserve estimation
• Seamless integration with 3D resource estimates
• Simulate variable density flow if required
• Use numerical modeling to evaluate and optimize production wellfield design
• Typical codes include MODFLOW-USG and MODFLOW-SURFACT

Hard Rock Mining

• All aspects of mining operations from environmental impacts, water supply, and feasibility through mine operations and closure
• Mine dewatering and depressurization assessments
• Modeling in support of permitting requirements
• Pore-pressure modeling
• Tailings seepage evaluations
• Water supply development
• Typical codes include MODFLOW-USG and MODFLOW-SURFACT

Uncertainty Assessment

• Provide confidence bounds with model projections
• Use multiple techniques, from simple to complex
• Communicate uncertainty with clients and stakeholders
• GoldSim Certified Solution Provider

In addition, we often use 3D Geologic Models such as Leapfrog to develop input and present results in a way that is accessible to project stakeholders. Our 3D Geologic Modeling includes:

• Conceptual hydrogeologic model development
• Numerical model input development
• 3D visualization
