About the Symposium

Purpose

The Symposium's primary purpose is to focus attention on extreme precipitation events in California watersheds responsible for producing floods and placing life and property at risk. We hope this attention will increase our knowledge and understanding of extreme precipitation events, so we can:

  1. Provide better information on the size of large floods for land use and flood risk management planning efforts, and
  2. Increase the warning time in advance of large floods.

The Symposium is designed to be an informal setting for an interesting day of scientific and technical presentations with time for questions and answers. The cost is kept low to encourage participation by a diverse audience.

History

The first Symposium was convened in 1994, and held annually thereafter (except for 2000). From 1994 to 2003, the Symposium was known as the California Weather Symposium. The name was changed in 2004 to California Extreme Precipitation Symposium to acknowledge our emphasis on extreme precipitation. From the initial gathering of 55 weather aficionados, participation has grown to over 200.

Over the years our primary focus has been on precipitation responsible for floods. Flooding is of primary concern to government agencies responsible for protecting life and property located in California's floodplains and the private sector professionals assisting them.

In 2003, the Symposium was invited to be part of the larger Lower American River Science Conference and in 2005 and 2007 the American River Watershed Conference, each organized by the College of Natural Sciences and Mathematics, California State University, Sacramento.

Gary Estes, the Founding Coordinator of the California Extreme Precipitation Symposium, and Matt Fleming, a speaker from the 2014 Symposium, with the Hydrologic Engineering Center of the U.S. Army Corps of Engineers, were invited as speakers for the International Symposium on California Extreme Precipitation. The event, sponsored by the Japan Society of Hydrology and Water Resources, Disaster Prevention Research Institute, Kyoto University, and the Japan Civil Engineers Consultants Association, was held in Tokyo, Japan, on February 7, 2015.

The purpose of this International Symposium was to increase efforts to share scientific knowledge among private, government, and academic sectors in order to prepare against atmospheric river-induced disasters.
