Watershed Modeler

The Cadmus Group is in search of a mid-level watershed modeler to join our Watershed Science & Management Team on a full- or part-time basis. The Watershed Modelers will coordinate and execute all aspects of watershed runoff and surface water quality modeling using a range of state-of-the-art modeling tools, in support of the development of total maximum daily loads (TMDLs) and other watershed assessment efforts.

Duties:

Primary responsibilities include: determination of data needs (and acquisition of data) for watershed studies and model simulations (e.g., GIS data, land use and soil data, meteorological data, hydraulic data, etc.); model calibration and verification; statistical analyses and quality control on model input data and modeled results; hydraulic simulation of streams and rivers (e.g., stages and discharges); and pollutant fate and transport simulation using receiving water quality models for range of pollutants (e.g., nutrients, sediments, pathogens, metals, toxics, etc.). The individual will regularly summarize and present model results to clients, contribute to the preparation of professional technical reports, and assist with the conceptualization of technical approach for new projects.

Required:

• Bachelor’s degree in hydrology, water resources, civil engineering, environmental, or natural sciences
• Demonstrated experience with surface water quality modeling (including hydrology/flow models) and simulation techniques, including pollutant fate and transport (including nutrients)
• Demonstrated experience and ability in developing, calibrating, validating, and implementing a range of watershed models and surface water quality models, especially those typically used for the development of TMDLs (e.g., QUAL2E/QUALK, HSPF, SWAT, LSPC, BATHTUB, CE-QUAL-W2, etc.)
• Experience applying statistical and other quantitative techniques to watershed assessment projects
• Considerable knowledge of watershed assessment and planning principles
• Ability to work independently, efficiently, and in an organized manner with very strong attention to detail
• Ability to work on multiple projects concurrently and meet tight deadlines.
• Strong problem-solving abilities
• Effective communication skills, in writing, in person, and on the telephone
• Experience working Microsoft Office Suite software and Web browsers
• A cheerful and outgoing personality, positive attitude, sense of humor, and team spirit

Preferred:

• Master’s degree in hydrology, water resources, civil engineering, environmental, or natural sciences
• Applied knowledge of the Clean Water Act
• Experience developing TMDLs
• Experience with urban stormwater modeling (e.g., SWMM, HEC-HMS, etc.)
• Experience using R, or another programming language with the ability to quickly learn advanced R skills
• Experience with Microsoft Excel/Word macros and Visual Basic for Applications (VBA) programming
