Hydrology Professional Development Series (PDS) 3 : Manage a Hydrology Program

PDS Statement of Responsibility : Manage the WFO hydrology program with integrated resources and tools to provide accurate and timely information for partners and the public.

Executive Producer(s):
John Bradley - Water Resources/Analysis, Forecast and Support Office/ NWS.

Description of the Area of Responsibility : In support of hydrologic forecast and warning operations, managing the WFO hydrology program ensures the integrity and relevancy of NWS hydrologic services for partners and users. The Hydrology Program Manager (HPM) provides WFO hydrologic leadership, expertise and outreach for flooding, drought, water supply and other local hydrologic issues. Duties are to build and maintain situational awareness and coordination between RFCs and partner agencies as well as maintain the local data program, conduct field work, and configure software. Responsibilities also include training staff to support delivery of NWS hydrologic information during normal and backup operations in addition to gathering and analyzing post event information to improve services.

List of Professional Competency Units (PCUs): In support of hydrologic forecast and warning operations, managing the hydrology program ensures the integrity and relevancy of NWS hydrologic services for partners and users.

  • Lead and conduct WFO Hydrologic Outreach
  • Identify, plan and coordinate changes in the WFO hydrology program
  • Maintain WFO hydrology database and software applications
  • Conduct field work to support WFO hydrology programs
  • Analyze and Verify WFO Hydrologic Events

PCU 5: Analyze and Verify WFO Hydrologic Events

SMEs:
Britt Westergard - ALY - WFO Albany, NY - britt.westergard@noaa.gov
Mary Lamm - PAH - WFO Paducah, KY - mary.lamm@noaa.gov
Michael Garrison - BMX - WFO Birmingham, AL - michael.garrison@noaa.gov

Description of Job Competency to be Achieved :
Analyze and perform verification of WFO hydrologic events, both high- and low-flow, to ensure a complete investigation of these events. This will improve data collection, forecast and warning operations, and internal and external collaboration in flood, drought, and normal conditions.

Description of Need :
Documenting details in flow patterns during high- or low-water events can lead to improvements in forecast crests, low-water minima, and their timing. Collecting and verifying all available precipitation reports, river reports, and high- or low-water impacts during an event and post-event are critical to improved analysis of the scope and magnitude of the flood or drought event. Improved data may lead to more accurate downstream and inundation forecasts and impact statements during current events and for all locations with future events.
