Core Responsibilities

Primary Functions

Lead development, calibration, and validation of hydrologic and hydraulic models (HEC-HMS, HEC-RAS, EPA SWMM, MIKE SHE or similar) for watershed-scale floodplain analysis, flood risk mapping, and stormwater management design, ensuring model inputs, assumptions, and results are clearly documented and defensible for permitting and public review.
Design and execute water quality monitoring programs, including sampling plan development, field collection (in-situ measurements and grab samples), chain-of-custody procedures, laboratory coordination, and interpretation of results against regulatory thresholds and TMDLs.
Prepare detailed technical reports, memos, and permit application packages (NPDES, MS4, water quality certification) that synthesize hydrologic and water quality findings, summarize methods and uncertainties, and recommend practical mitigation or operational strategies for clients and regulators.
Conduct watershed-scale water balance and mass-balance analyses to quantify surface water, groundwater interactions, recharge, evapotranspiration, and consumptive use under current and future scenarios to inform resource allocation and drought contingency planning.
Perform GIS-based spatial analysis and map production for watersheds, drainage networks, impervious surfaces, land use change detection, and infrastructure inventories using ArcGIS Pro, QGIS, and remote sensing datasets to support planning and permitting.
Analyze continuous monitoring and telemetry datasets (stream gauges, rainfall stations, flow meters, SCADA) to detect trends, perform QA/QC, gap-fill time series, and produce event-based and seasonal analyses used for modeling inputs and operational decision-making.
Apply statistical and data science techniques (regression, trend analysis, uncertainty analysis, synthetic hydrograph generation) using Python, R, or MATLAB to interpret hydrologic signals, generate design storms, and quantify model sensitivity and predictive confidence.
Support stormwater infrastructure and green infrastructure design by producing runoff hydrographs, sizing conveyance and detention systems, evaluating low-impact development alternatives, and preparing conceptual and detailed engineering calculations.
Coordinate and communicate with federal, state, and local regulatory agencies (EPA, state water boards, USACE, state departments of environmental quality) to obtain permits, respond to agency comments, and ensure projects meet regulatory and policy requirements.
Lead field investigations and site assessments including channel surveys, cross-section and profile measurements, topographic verification, groundwater monitoring well installation oversight, and health & safety compliance during fieldwork.
Evaluate climate change and land-use change scenarios to assess future flood risk, water availability, and water quality impacts; incorporate downscaled climate projections and sensitivity scenarios into planning products.
Develop and maintain centralized water data repositories, standardized metadata, and data management workflows to ensure reproducibility, version control, and easy retrieval of hydrologic and water quality data for multi-year projects.
Provide technical support for environmental impact assessments and CEQA/NEPA documents, writing methods and results sections, assessing project impacts on water resources, and recommending mitigation measures to reduce adverse effects.
Prepare grant applications, funding proposals, and technical scopes for water resource studies and infrastructure projects; quantify benefits, costs, and timelines to support procurement and funding decisions.
Provide peer review of hydrologic and hydraulic analyses produced by internal staff or external consultants, verifying model assumptions, boundary conditions, and compliance with agency guidance and design standards.
Support water allocation modeling and policy analysis by translating technical hydrologic outputs into operational metrics such as yield estimates, reliability curves, and scenario-based supply assessments for planners and decision-makers.
Integrate groundwater and surface water data to evaluate conjunctive use, baseflow contributions, and recharge opportunities, working with hydrogeologists to produce joint surface-groundwater assessments.
Design and implement QA/QC procedures for field and laboratory data, model inputs, and deliverables to ensure high data integrity, accurate interpretation, and defensible recommendations in regulatory and legal contexts.
Present technical findings to non-technical stakeholders, elected officials, and community groups through clear visuals, executive summaries, and oral presentations that translate complex technical information into actionable insights for policy, operations, and community planning.
Manage multiple project tasks, deliverables, budgets, and consultants simultaneously; track milestones, prepare invoicing documentation, and provide timely status updates to project managers and clients.
Conduct risk assessments for floodplain development and critical infrastructure, combining hazard, exposure, and vulnerability analyses to prioritize mitigation investments and resilience planning.
Design and implement hydrologic data collection networks and sensor deployments, coordinate with IT/SCADA teams for telemetry integration, and develop automated reporting dashboards and alerts for operational monitoring.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis for cross-departmental planning, policy evaluation, and emergency response situations.
Contribute to the organization's water data strategy and roadmap, helping define standards for metadata, data storage, interoperability, and reproducible modeling practices.
Collaborate with engineering, planning, conservation, and legal teams to translate technical water resource findings into actionable recommendations and contract deliverables.
Participate in project planning, sprint planning, and agile ceremonies when working on interdisciplinary or software-focused water data projects to align priorities and deliverables.
Mentor junior staff and interns in field sampling techniques, modeling best practices, data management, and report writing to build departmental capacity.
Assist in public outreach and stakeholder engagement efforts by preparing outreach materials, responding to public comments, and participating in community meetings to explain water resource analyses and proposed solutions.
