Amir AghaKouchak is a Professor of Civil and Environmental Engineering and Earth System Science at the University of California, Irvine. His research focuses on natural hazards and climate extremes and crosses the boundaries between hydrology, climatology, remote sensing. One of his main research areas is studying and understanding the interactions between different types of climatic and non-climatic hazards including compound and cascading events. He has received a number of honors and awards including the American Geophysical Union’s James B. Macelwane Medal and the American Society of Civil Engineers (ASCE) Huber Research Prize. Amir is currently serving as the Editor-in-Chief of Earth’s Future. He has served as the principal investigator of several interdisciplinary research grants funded by the National Aeronautics and Space Administration (NASA), National Science Foundation (NSF), and National Oceanic and Atmospheric Administration (NOAA). Amir has a passion for nature and landscape photography, and he uses his photos for creating educational materials.

Flooding vulnerabilities of L.A. River’s Glendale Narrows spark concern amid record rain

Los Angeles Times  online


In the last decade alone, California has been hit with back-to-back cycles of historic drought followed by historic rain, snow and flooding. “I’m personally concerned about this because our levee systems are very, very old and basically made out of soil,” said Amir AghaKouchak, a UC Irvine professor. AghaKouchak co-authored a 2020 study on the impacts of climate change on levees protecting critical infrastructure–transmission lines, roads, railroads, natural gas and petroleum pipelines in densely populated areas such as Southern California’s coastal communities.

In California, there are more than 14,000 miles of urban and rural levees. They protect dry land, cities, towns, homes, businesses, farms and public property from floods. … "On average, they are 57 years old and many of them were built using standards that were much less rigorous than are current building practices," said UC Irvine Climate and Flood Scientist [Professor] Amir AghaKouchak. … "We're not doing enough. Lack of maintenance is one of the biggest issues in my opinion," said AghaKouchak. … "Future earthquake can cause actual collapse and failure," said AghaKouchak.

The state’s years-long drought may have also had a psychological effect on residents, who lately have been praying for rain, said Amir AghaKouchak, a civil and environmental engineering professor at University of California, Irvine. “Fire, when you see it, you immediately feel the danger,” he said. “But rain is different, especially in California, where we consider it a good thing.” Floods, then, can blindside people, he said. And it doesn’t take much water — sometimes just a quarter of an inch in a matter of minutes — to transform a benign hill into a mudslide, AghaKouchak said.

Will Iran's climate inaction fuel rising disaster threats?

Reuters  online


Amir Aghakouchak, an Iranian-American professor of civil and environmental engineering at the University of California, Irvine, who has written on water scarcity in the country, said he was not sure a higher profile would translate to action on the ground in Iran. "Unfortunately, when it comes to water and environmental management, I am not optimistic about the level of government engagement," he said.

“In cascading events, the sequence, timing and order of events really matter,” says Amir AghaKouchak, a professor of environmental and civil engineering at the University of California, Irvine. He adds that some events can take place over years, making it harder for scientists to model or predict their risks.

The next extreme floods could be even worse, a new study shows. But there’s a way to prevent that

CNN  online


Amir AghaKouchak, a co-author and civil engineer at the University of California at Irvine, told CNN that many parts of the country — including the St. Louis area and eastern Kentucky — are particularly vulnerable and need to make a lot of improvements to adapt to the rapidly changing climate.

But this an evolving status quo many societies and governments have to accept. “Heat waves happen more frequently now and they are spread around throughout the year,” Amir AghaKouchak, a University of California at Irvine professor, told my Washington Post colleagues. “This is the new normal and most likely it will only get worse in the future unless we take serious actions.”

Rainfall Totals: 1+ Inch of Rain in Parts of San Diego County Not Enough to Pull From Drought, Expert Says

NBC San Diego  online


UC Irvine professor of Civil & Environmental Engineering Amir AghaKouchak said while the rainfall was significant, it is not likely enough to pull the region out of drought. "We are towards the end of the rainy season. It is unlikely that we will see several [more] storms like this. So, most likely we will remain below average this year," AghaKouchak said. "The good news is that our reservoirs are not bad... It's better than last year, but we will remain under drought situation this year, at least that's how it looks like."

Changes in the exposure of California's Levee-Protected Critical Infrastructure to flooding hazard in a warming climate

Environmental Research Letters

2020 Levee systems are an important part of California's water infrastructure, engineered to provide resilience against flooding and reduce flood losses. The growth in California is partly associated with costly infrastructure developments that led to population expansion in the levee protected areas.

Impacts of ozone and climate change on yields of perennial crops in California

Nature Food

2020 Changes in temperature and air pollution affect agricultural productivity, but most relevant research has focused on major annual crops (for example, wheat, maize, soy and rice). In contrast, relatively little is known about the effects of climate change and air quality on perennial crops such as fruits and nuts, which are important to dietary diversity and nutrition, and represent ~38% of California’s agriculture by economic value.

Flash droughts present a new challenge for subseasonal-to-seasonal prediction

Nature Climate Change volume

2020 Flash droughts are a recently recognized type of extreme event distinguished by sudden onset and rapid intensification of drought conditions with severe impacts. They unfold on subseasonal-to-seasonal timescales (weeks to months), presenting a new challenge for the surge of interest in improving subseasonal-to-seasonal prediction. Here we discuss existing prediction capability for flash droughts and what is needed to establish their predictability.

Climate Extremes and Compound Hazards in a Warming World

Annual Review of Earth and Planetary Sciences

2020 Climate extremes threaten human health, economic stability, and the well-being of natural and built environments (e.g., 2003 European heat wave). As the world continues to warm, climate hazards are expected to increase in frequency and intensity. The impacts of extreme events will also be more severe due to the increased exposure (growing population and development) and vulnerability (aging infrastructure) of human settlements.

How do natural hazards cascade to cause disasters?


2018 This has been an exceptional year so far for natural disasters. Typhoons in Asia and Hurricane Florence hitting the US east coast have caused extensive damage, flooding and mudslides. In the past two months, Scandinavia, Spain and Portugal, the United Kingdom, North America and South Africa experienced fierce forest blazes.

Mountain snowpack response to different levels of warming


2018 Across the world, the seasonal montane snowpack stores and releases substantial amounts of water annually. As the global temperature is projected to rise, it becomes increasingly important to assess the vulnerability of the mountain snowpack. We therefore turn to the historical record to understand the extent to which snow water equivalent (SWE) and its centroid respond to different levels of warming.
