SC 209: California Mega-floods and the Connection to Atmospheric Rivers: A Hydrologic Perspective – Class presentations available for viewing

California’s geographical location, along with the diversity of geological terrain and features and proximity to the Pacific Ocean, subjects it to large variability in weather and climate. This variability complicates societal preparation for extreme events, such as floods and drought, which impact nearly all human systems. Historically, these extreme events, especially flooding events or so called “mega-floods,” have had a dramatic impact to the population and they will continue to do so in the future. This joint lecture discussed one of the atmospheric phenomena known to cause widespread flooding across California – Atmospheric Rivers, originating in the tropical, moisture-rich Pacific Ocean, which impact the California coastline with disastrous implications to urban flooding, infrastructure damage and agriculture. The role of climate variability and climate change will be discussed, along with state-of-the-art observation platforms, modeling systems and forecasting methods.

The UCI CHRS is an interdisciplinary group that brings together faculty and researchers from the Departments of Civil and Environmental Engineering and Earth System Science. The group jointly conducts research to advance the knowledge of the water and energy cycle at scales ranging from local watersheds to continental, using hydrologic processes, remote sensing information, and computer models. The majority of CHRS research activities are funded by NASA, NOAA, and NSF.
