  • Perform hydrological modeling of historical and future floods (both riverine and non-riverine) in Montgomery County watersheds using HEC-HMS and HEC-RAS, or comparable software.
  • Perform quality control including but not limited to understanding, quantification, and analysis of components of the hydrological cycle, including soil moisture, snow, ground and surface waters, precipitation, evapotranspiration, and runoff, utilizing innovative remote sensing and numerical modeling techniques.
  • Create metadata and fact sheets supporting the data products and examine the results under different climate scenarios.
  • Perform data analyses using GIS and remote sensing data to answer questions about physical and natural resources.
  • Design, build, and maintain GIS applications including research, database design, data maintenance, and mapping analysis.
  • Performs spatial analyses to design, produce and provide map products, tabular data and reports.
  • Prepare presentations, reports, data visualizations, and other high-quality communication materials.
  • Create ArcGIS Online Maps, Applications, StoryMaps, Dashboards, etc. to improve access to, analysis of, and communication about climate change, and other natural and infrastructure resources.

The ideal candidate will have considerable experience in data analysis, statistical methods, climate change effects on the water cycle and climate modeling; experience with Hydrologic Modeling Systems; and demonstrated experience in GIS, geospatial data compilation and analysis.

To ensure a positive workplace and to comply with federal, state and County laws, the incumbent is responsible for completing mandatory trainings within the first three to six months or within the specified timeframe.


Experience:  Three (3) years of professional experience in information technology field in Geographic Information Systems (GIS) or Remote Sensing related to modeling, data visualization, or cartography.
