Silver Jackets Webinar on Changes in the Magnitude and Frequency of Riverine Flooding in the United States
The May 16, 2018 Silver Jackets Webinar presentation was given by Robert Hirsch, Research Hydrologist for the U.S. Geological Survey.
Effective flood mitigation requires sound information about the risks, for example how high are stream flows and how often one can expect floods to occur on any given river. Flood risk information depends on long-term streamflow data, detailed geographic information about watersheds and floodplains, and statistical analyses of these data. Historically, the assumption has generally been that the relationship of frequency and magnitude never changes over time.
Today the hydrologic science community and citizens in general recognize that there are reasons that changes could be taking place, driven by factors such as changes in land use, engineering works, and in climate. An important part of planning for the future is knowing what changes have happened in the past and trying to learn about the drivers of those changes. Robert Hirsch shared research completed by the USGS to understand these changes.
The presentation (pdf, 2.61 MB) and recorded session (mp3, 9.32 MB) are available.
