Join us on November 12, at 4:30 PM in room 2204 in the Edward St. John Teaching and Learning Center. Dr. Karen Prestegaard will give a talk about changes in precipitation timing and their links to flash floods and droughts. We hope to see you there!
Headshot of Dr. Karen Prestegaard. Wed. 11/12: Karen Prestegaard. Changes in precipitation timing and their links to flash floods and droughts. In the past decade, many regions of Maryland have experienced hot, dry periods during summer months leading to flash droughts that have affected crops, forests, and stream baseflow. In the same time period, the intensity of summer storms has been increasing, with some sites experiencing multiple storm events in excess of the 100-year storm in the same year. My research group has been developing techniques to characterize precipitation clustering and the impacts on streamflow. We also have been monitoring small streams in Maryland urban and non-urban areas to measure flood rise rates, stream channel erosion, and the underlying geologic, geomorphic, and land use characteristics that mitigate or enhance these stream responses. Our goal is to provide information that can be used to identify existing flood hazard regions and to identify areas that have enhanced responses when developed.

Dr. Sujay Kaushal, a professor and researcher in the Department of Geology at UMD, was featured in the article "Why salt is threatening America's rivers and drinking water," published in the Washington Post on 6/4/25.
Why salt is threatening America's rivers and drinking water. Written by Kasha Patel. June 4, 2025. Washington Post. Tall tan grasses known as Phragmites australis are seen along the Anacostia River in Bladensburg, Maryland. These invasive plants, which grow in salty environments, are warning signs of the changing chemistry of the environment. Freshwater ecosystems, like the Anacostia River, are growing saltier year-round. That increasing salinity has not only been linked to mass deaths of aquatic life and damaged infrastructure, but some people can even taste it in drinking water. Too salty to drink. Around the DC metro area, the biggest salt contamination comes in the winter. People apply an abundance of salt on roads – if you can hear it crunch under your feet, it’s too much – and the excess runs off into riverways. The biggest source around DC and other major northern inland cities is an overapplication of road salt to thaw winter ice, which enters into rivers or the ground, According to sujay kaushal, professor and reseacher at umd and member of the Climate resilience network.

Friday ice update - #Arctic sea ice extent is currently the 6th lowest on record (JAXA data)

• about 120,000 km² below the 2010s mean
• about 700,000 km² below the 2000s mean
• about 1,220,000 km² below the 1990s mean
• about 1,620,000 km² below the 1980s mean

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between April and July by looking at the decadal average line positions.
