Technical Officer, Hydrogeological Modelling

Responsibilities Provide advanced technical expertise in hydrogeological modelling, including numerical flow and solute transport simulations, conceptual model development, and parameterization, to support Geoscience and other functional groups at the NWMO in support of on-going site characterization activities and the regulatory decision-making process. Contribute to the design, acquisition, processing, and integration of hydrogeological datasets, ensuring consistency, quality, and suitability for use in groundwater flow models at various scales. Collaborate on hydrogeological modelling projects, including developing detailed work plans, performing model setup and calibration, conducting sensitivity and uncertainty analyses, troubleshooting model issues, and collaborating with multidisciplinary teams to integrate geological, geochemical, geomechanical, and surface hydrology data into cohesive model frameworks. Support the development of contracts for hydrogeological data acquisition, modelling, and integration projects including: the development and issuance of contracting documents (RFPs etc.); the evaluation and selection of contractors; and monitoring contractor performance from technical, budget, and schedule perspectives. Produce geoscientific reports or other documents and/or presentations, as required, related to geoscientific research and supporting documents. Communicate (written and oral) findings of geoscientific work to technical and non-technical audiences. Perform other duties as required. Contribute as required to committees’ task forces to conduct studies and or carry out work programs. Appear before government authorities, agencies, regulator bodies and legislative hearings as an expert in hydrogeological modelling, as required. Qualifications and Experience A 4-year university degree in a relevant major such as hydrogeology, geology, geophysics, geotechnical, environmental or civil engineering. Demonstrated experience in quantitative hydrogeological modelling and analysis. Demonstrated experience in developing approaches for modelling groundwater systems in crystalline rock environments.. Demonstrated experience in incorporating multi-disciplinary geoscientific data to investigate groundwater migration, including geological model elements and field hydraulic data. Experience with relational hydrogeological databases, GIS, scientific visualization, groundwater flow and solute transport modelling, including the development of pre- and post-processors for model inputs and outputs Experience with sensitivity and uncertainty analyses or methods in groundwater modelling studies. Demonstrated understanding of data QA/QC and data management standards. Experience in reviewing and writing high-quality hydrogeological modelling technical reports and journal publications, and in developing other presentations of a technical nature. Demonstrated ability to work within a multi-disciplinary team and interact with external contractors. Excellent communication skills, both written and verbal. Experience in project management and the ability to facilitate work projects and liaise between a variety of technical and non-technical colleagues. Preferred P.Geo. or P.Eng. is considered an asset. A master’s or Ph.D. degree with specializations in hydrogeological modelling would be considered an asset. Knowledge and experience in ArcGIS, Paraview, and solute transport modelling (HydroGeoSphere, OpenGeoSys, MODFLOW, MT3D, MODPATH) Knowledge and experience with programming or scripting languages (e.g. VBA, Python, Fortran, bash, etc.) for the development of pre- / post-processors, application of numerical methods, and scientific computing. Ability to provide group-leading hydrogeological modelling expertise in support of advancing site understanding and the regulatory process for a Deep Geologic Repository is considered an asset.
