Job Description Summary
Performs routine (journey-level) to advanced (senior-level) geosciences or hydrological work. Work involves the compilation and documentation of source information; adherence to set processes and standards; the use and manipulation of various programming scripts; development and calibration of numerical groundwater flow models; analysis and interpretation of groundwater modeling results and water budgets; the use of GIS software to prepare maps, geodatabases, process data, and/or review input/out from models; writing reports; providing presentations; reviewing, analyzing, coordinating, or overseeing the collection and analysis of data and samples for technical reports and projects; preparing, reviewing, or evaluating model designs, results, and analysis and reports; and ensuring compliance with applicable statutes and regulations. May train or supervise others. Works under moderate to minimal supervision, with limited to considerable latitude for the use of initiative and independent judgment. Reports to the Manager of the Groundwater Availability Modeling Department.


Essential Job Functions
• Collects and reviews technical data, analyzes findings, and assists with data calculations and the development of recommendations for programs or projects.
• Conducts scientific hydrogeological investigations to ensure that accurate and appropriate information is available for use in water resource management decisions; specifically, statutorily required model simulations, development of groundwater models, water budget analysis, model-related data evaluations, and documentation of related activities.
• Studies and documents quantities, distribution, disposition, and development of groundwater and surface waters in support of groundwater modeling.
• Maintains and prepares records and reports and presents technical evaluations and plans.
• Implements technical projects and completes design preparation, plans, estimates, and calculations.
• May develop or use hydrologic models for various applications.
• Reviews the activities of contractors funded through the Groundwater Availability Modeling Program.
• Researches and delivers written and verbal responses to public, inter, and intra-agency inquiries. May include
presentations at public meetings summarizing modeling studies and simulations.
