Advances in Display and Analysis of Groundwater Data
by Steve Wilson and Daniel AbramsSep 17, 2020 11:45 am2 Views
The Water Survey has been a leader in groundwater science since its inception in 1895. Water Survey staff have developed innovative ways to analyze and visualize data, from painstakingly soldered flow models using electricity, to digital flow models like the widely used Prickett-Lonnquist Aquifer Simulation Model (PLASM), to more recent interactive maps and a new approach to developing potentiometric surfaces using MODFLOW. Learn more about the past, present, and future of the Water Survey's groundwater data innovation in this StoryMap.

Rethinking short-term droughts in Illinois
by Tiffany JolleyApr 14, 2020 9:00 am1 View
While there is no universally accepted definition of drought, contemporary definitions look at a percentage of precipitation over a protracted period of time, in most cases over the course of a year. Some say this approach leaves people and communities vulnerable to a different type of drought – flash droughts.

Researchers update Illinois standards for storm frequencies
by Lisa SheppardMay 2, 2019 10:00 am1,788 Views
As heavy rainstorms become more frequent and stronger than in the past, municipal drainage systems designed from outdated standards often fail, resulting in flooding and financial losses. Researchers at the Illinois State Water Survey (ISWS) have recently applied newer data to update ISWS Bulletin 70, the publication that provides the state standards for expected extreme storms.

ISWS participates in project to help predict air quality, enhance crop yields
by Tricia BarkerSep 12, 2018 8:45 am1 View
Tracking how air moves at night near the Earth's surface could provide insights into how air pollution spreads and when it's best to apply pesticides. This week, a team of University of South Carolina and University of Illinois researchers will launch a project to do just that. The two-month experiment -- called Stable Atmospheric Variability and Transport, or SAVANT -- will run from Sept. 15 to Nov. 15 in and near Mahomet, Illinois, and will measure air flow in what's known as a stable boundary layer.

ISWS investigates the potential for stormwater credit trading in Cook County
by Lisa SheppardFeb 9, 2018 5:30 pm5 Views
In the Chicago region, rain and snowmelt often overwhelm sewer systems, causing street flooding and basement back-ups. Pollutants from sewer systems flow into nearby rivers and Lake Michigan. Even in areas with separate storm and sanitary sewers, overflow from severe storms carries pollution into the Chicago area waterways system, adversely affecting water quality and habitat. This problem is expected to worsen as climate change progresses and storms grow larger and more frequent.
