How much do modflow feflow jobs pay per year?

As of Jun 7, 2026, the average yearly pay for modflow feflow in the United States is $93,020.00, according to ZipRecruiter salary data. Most workers in this role earn between $83,000.00 and $103,000.00 per year, depending on experience, location, and employer.

What are the typical challenges faced when working as a Modflow/Feflow modeler in groundwater projects?

One of the main challenges Modflow/Feflow modelers encounter is accurately representing complex subsurface hydrogeology with limited data, which often requires making informed assumptions and iterative model calibration. Collaboration with geologists, field engineers, and project managers is essential to ensure that model inputs reflect real-world conditions and project objectives. Additionally, modelers must stay current with software updates and evolving regulatory requirements, as well as effectively communicate technical results to non-specialist stakeholders. Managing project deadlines while ensuring the quality and reliability of model outputs is also a common aspect of the role.

What are the key skills and qualifications needed to thrive as a Modflow/FEFLOW Hydrogeological Modeler, and why are they important?

To thrive as a Modflow/FEFLOW Hydrogeological Modeler, you need a strong background in hydrogeology, groundwater modeling, and environmental engineering, typically supported by a relevant degree such as geology, hydrology, or civil engineering. Expertise in using Modflow and FEFLOW software, GIS tools, and data analysis platforms is essential, and certifications in groundwater modeling can be advantageous. Strong analytical thinking, attention to detail, and effective communication are key soft skills for interpreting complex data and presenting findings to multidisciplinary teams. These skills ensure accurate modeling, effective project delivery, and informed decision-making in water resources management.

What is the difference between Modflow Feflow vs Groundwater Modeler?

AspectModflow FeflowGroundwater Modeler
CredentialsHydrogeology degree, modeling certificationsHydrogeology or environmental science degree, modeling experience
Work EnvironmentResearch labs, consulting firms, government agenciesEnvironmental consulting, government agencies, research institutions
Usage in IndustrySpecific software (Modflow, Feflow) for groundwater flow modelingBroader groundwater modeling tasks, including Modflow and Feflow

Modflow Feflow specialists focus on using specific software tools for groundwater flow modeling, often requiring specialized certifications. Groundwater Modelers have broader roles, utilizing various modeling software including Modflow and Feflow, in diverse environments like consulting and government agencies. While both roles involve groundwater modeling, Modflow Feflow experts are more specialized in software application, whereas Groundwater Modelers handle a wider range of modeling tasks.

What are Modflow and Feflow?

Modflow and Feflow are both specialized groundwater modeling software used by hydrogeologists and environmental engineers. Modflow, developed by the US Geological Survey, is widely considered the industry standard for simulating groundwater flow in porous media. Feflow, developed by DHI, offers advanced capabilities for simulating groundwater flow, contaminant transport, and heat transfer, with support for complex geological and hydraulic conditions. Both tools help professionals analyze groundwater systems to support water resource management, environmental impact assessments, and remediation projects.

The ideal candidate is a recognized or emerging subject matter expert in hydrogeology, comfortable taking ownership of project outcomes, mentoring junior staff, and contributing to the continued growth of our water resources practice.
Responsibilities:
  • Lead and direct hydrogeological studies to evaluate groundwater availability, quality, flow systems, and aquifer characterization for mining, environmental, and water resources projects.

  • Design and oversee the development, calibration, and application of analytical and numerical groundwater flow and transport models (e.g., MODFLOW, FEFLOW) under fully saturated and variably saturated conditions.

  • Provide senior technical review and sign-off on hydrogeologic analyses, reports, and designs to ensure technical rigor, quality, and compliance with client and regulatory expectations.

  • Integrate hydrogeologic assessments with geotechnical, environmental, and surface water studies to support mine planning, dewatering, water supply, and environmental impact assessments.

  • Develop and evaluate groundwater monitoring networks, pumping tests, and data acquisition programs; interpret field and laboratory data for use in design and decision-making.

  • Manage medium to large, multi-disciplinary projects, including scope development, budgeting, scheduling, resource planning, and risk management.

  • Serve as a primary point of contact for key clients; build and maintain long-term client relationships through consistent, high-quality delivery and proactive communication.
