WE03 - Hydrometeorological Forecasting: Making the Most of What is Available

Aug 29, 2018 8:30am ‐ Aug 29, 2018 9:20am


The cheerful TV weather person comes on the local news on Friday and talks about a 40% chance of rain for Monday. But come Monday, a severe storm causes local flooding and a combined sewer overflow! Precipitation forecasting has improved exponentially over the last 20-years, yet for public works operations, a profound disconnect exists in how forecast information is acquired (access and timing), perceived (interpreted), and used for decision-support (mitigation.) This presentation will discuss the tools that are available to resolve this issue and provide innovative approaches for using hydro-meteorological information in managing stormwater and wastewater programs.

Learning Objectives: At the conclusion of this session, you will be better able to: 

  • Identify reliable sources for hydro-meteorological information.
  • Discuss how to better use and apply forecast information to stormwater, reservoir, and wastewater management.
  • Make more informed decisions to mitigate the impacts of severe storms and flooding.
