January 23, 2026 -Lecture: Flash Floods in Semi-Arid Landscapes – FULL (waitlist)
Lecture: Flash Floods in Semi-Arid Landscapes – FULL (waitlist)
Special Earth Sciences Weekend!
Speaker: Suzanne Walther, Ph.D., University of San Diego
PROGRAM IS FULL - PLEASE CALL ABDNHA at 760-767-3098 to get on waitlist.
It has been said that the two most common ways to die in the desert are from thirst and from drowning. Flash floods are the leading weather-related cause of death in the U.S. and many parts of the world, and cause billions of dollars in damage. Dr. Suzanne Walther is a fluvial geomorphologist. She studies rivers, streams, floods, sediment movement, and how the natural flow of water shapes the landscape, interacts with ecosystems, and significantly impacts human development. The focus tonight is on flash floods in semi-arid areas, such as Borrego Springs, where they can occur, the conditions that lead to their formation, the powerful forces they unleash, their effects on water supply and drought, and what can be done to mitigate their destructive impact on human development. In the ABDNHA Library. General Public: $12, Members: $10, Volunteers: $8. You can register online at abdnha.org or at the Nature Center, 760-767-3098.
