Groundwater Modeler

Position Title: Groundwater Modeler Position Type: Full-Time Location: Woodland, CA MODELER RESPONSIBILITIES (Knowledge in CA Groundwater): Develop and calibrate numerical hydrologic models ranging in complexity up to basin-scale integrated hydrologic and solute transport models. Use of finite difference and/or finite element model software such as MF-OWHM, MODFLOW 6, IWFM, and related model codes. Develop and use scripts (e.g., Python, R, Matlab) to develop model input files and process and evaluate model output. Working with various types of hydrologic, engineering, and hydrogeologic data and software to develop hydrogeologic conceptual models Working in small groups to complete project tasks while also providing project management oversight, if required. Preparation of written documents and client deliverables, including technical presentations, public engagement, reports, and technical memoranda. Aquifer test data collection and analysis. Involvement and management of multiple projects simultaneously. Use of analytical solutions of common hydrogeologic problems. Modeler REQUIRED QUALIFICATIONS (Knowledge in CA Groundwater): B.S. degree in Geology and M.S. degree in Hydrogeology or related disciplines Minimum of 5 years of experience in consulting in California with a primary focus on groundwater or integrated hydrologic modeling. Proficient in using finite difference and finite element model codes such as MF-OWHM, MODFLOW 6, and IWFM. Fluency in the use of a scripting language such as Python, R, MATLAB, etc. Experience in the calibration of groundwater models using PEST or PEST++ software.
