Overview

Lead GIS workflows for hydropower, watershed and environmental projects

Key Responsibilities

• hydraulic modeling
• gis lead
• dashboards
• data management
• geodatabase
• qa/qc

Tasks

-Prepare and translate inputs and outputs for 1D/2D hydraulic, sediment transport, and habitat models, ensuring spatial consistency and model-ready datasets. -Serve as GIS lead in proposal development, project planning, and data-management strategy for multi-disciplinary teams. -Develop basemaps, dashboards, and story maps to communicate modeling results and monitoring data to clients, regulators, tribes, and the public. -Mentor junior staff in geospatial methods, database management, and quality assurance practices. -Produce high-quality cartographic and visualization products for technical reports, permitting, and stakeholder engagement. -Conduct hydrologic and terrain analyses—watershed delineation, change detection, floodplain mapping, sediment characterization, and habitat suitability modeling. -Maintain metadata, QA/QC, and data management standards to support transparency, repeatability, and defensible technical deliverables. -Manage, process, and QA/QC large spatial datasets (LiDAR, topobathymetric surveys, DEMs, orthophotos, UAV-SfM) for use across engineering, geomorphic, and ecological disciplines. -Build geodatabases and automated geoprocessing workflows (ModelBuilder, Python, SQL) to ensure efficient, reproducible analyses and defensible regulatory documentation (FERC, NEPA/CEQA, ESA). -Lead GIS workflows supporting hydropower relicensing, dam removal, watershed modeling, hydraulic analysis, and environmental compliance projects. -Collaborate closely with engineers, geomorphologists, hydrologists, and biologists to integrate GIS analyses into design, modeling, and decision-making.
