Core Responsibilities

Primary Functions

Develop, calibrate, and execute complex one- and two-dimensional hydrologic and hydraulic models (e.g., HEC-RAS, HEC-HMS, SWMM) to simulate riverine systems, floodplain dynamics, and stormwater runoff.
Conduct detailed floodplain and floodway analyses, including preparing and processing LOMR/CLOMR applications and supporting documentation for FEMA submissions.
Perform comprehensive watershed assessments and characterizations to support water quality improvement projects, land use planning, and resource management strategies.
Design, install, and maintain hydrometric monitoring networks, including data loggers, sensors, and telemetry systems for collecting real-time water level, flow, and quality data.
Collect, process, and perform rigorous quality assurance/quality control (QA/QC) on large hydrological and meteorological datasets from various sources.
Author detailed technical reports, memorandums, and scientific papers that clearly document methodologies, analyses, results, and recommendations for technical and non-technical stakeholders.
Utilize Geographic Information Systems (GIS) for advanced spatial analysis, including watershed delineation, terrain analysis, land use classification, and creating high-quality cartographic outputs for reports and presentations.
Conduct field investigations to gather site-specific data, including stream gauging, water quality sampling, channel morphology assessments, and infrastructure inspections.
Analyze long-term climate data and trends to assess potential impacts on water availability, flood frequency, and ecosystem health, incorporating climate change projections into models.
Support the engineering design of hydraulic structures such as culverts, bridges, dams, and stormwater management facilities by providing critical design flow and water surface elevation data.
Evaluate the hydrological impacts of proposed development projects, mining operations, or land-use changes and recommend effective mitigation measures.
Provide technical expertise and support for environmental permitting processes, ensuring compliance with local, state, and federal regulations like the Clean Water Act.
Develop and apply statistical methods to analyze hydrologic data, perform frequency analysis (e.g., flood frequency), and identify trends or anomalies.
Prepare and deliver compelling presentations to clients, regulatory agencies, and the public to communicate project findings and support decision-making processes.
Manage the hydrologic and hydraulic components of multi-disciplinary projects, ensuring tasks are completed on schedule, within budget, and to a high technical standard.
Conduct dam break analyses and prepare inundation mapping to support the development of Emergency Action Plans (EAPs) for dam safety programs.
Perform water balance calculations for reservoirs, watersheds, and industrial sites to support water supply planning and operational decisions.
Assess stream stability and sediment transport dynamics to inform channel restoration design and erosion control projects.
Review technical studies, models, and reports prepared by other consultants or agencies to ensure technical accuracy and soundness of approach.
Mentor junior staff, providing technical guidance on modeling techniques, data analysis, and professional best practices in the field of hydrology.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to answer specific questions from project managers and clients.
Contribute to the organization's data strategy and roadmap by identifying new data sources and innovative analytical techniques.
Collaborate with business units to translate data needs into engineering requirements for new software tools or data collection efforts.
Participate in sprint planning and agile ceremonies within the data engineering team if the project requires it.
Assist in the preparation of proposals and business development efforts by providing technical scope, budget estimates, and methodological descriptions.
Stay current with emerging research, technologies, and regulatory changes in the water resources field through continuous professional development.
