Job Description Summary
Performs advanced to highly advanced (senior-level) modeling and/or engineering work for the Coastal Science Program in the Surface Water Division to support regional and state flood planning in Texas. Work involves developing, maintaining, and applying hydrologic, hydraulic, and hydrodynamic models across river, estuary, and open ocean scales. Work involves establishing goals, objectives, technical standards, methods, and procedures for coupling inland and coastal models to assess compound (riverine and storm surge) flood risk. Plans, oversees, and participates in scientific and engineering studies of state streams, rivers, bays, estuaries, and ocean. Serves as a liaison and gives presentations concerning coastal flood modeling at public meetings; provides technical support to stakeholders and customers; and, develops working relationships with state and federal agencies, academic institutions, and private contractors to advance coastal modeling. May train others. Works under limited to minimal supervision, with considerable to extensive latitude for the use of initiative and independent judgment. Reports to the Manager of the Coastal Science Department.
Essential Job Functions
• Plays a senior technical role in the Coastal Science department to improve existing models, operationalize new models, and develop the strategy and methods for coupling inland and coastal models to support compound flood risk analyses in Texas.
• Develops, maintains, and applies hydrologic, hydraulic, and hydrodynamic models of rivers, estuaries, and open ocean.
• Writes, executes, and maintains programs and scripts for model execution, analysis, and data visualization.
• Writes, reviews, and evaluates scopes of work, technical memos, reports, work process, and policy documents.
• Serves as a liaison for the TWDB at public meetings and develops working relationships with federal, state, and local agencies, academic institutions, and private contractors to advance coastal flood modeling.
• Provides quality customer service and technical support to internal and external customers and stakeholder committees.
• Delivers presentations to technical and non-technical audiences.
• Manages contracts related to inland and coastal modeling or monitoring.
• Assists with planning field studies and resulting data management; may assist with on-site work, equipment installation, and data acquisition.
