Using new and improved technologies, the Iowa Flood Center has deployed a hydrologic network to measure real-time conditions in each of the eight rural watersheds involved in the Iowa Watershed Approach.

“The university [of Iowa] has been really good to us here,” Iowa County farmer Stewart Maas says. “I’ve got a lot of respect for the hydrology department.” —Stewart Maas and son Jared make use of data produced by an IFC hydrologic station on their property

Project Description:

Through the Iowa Watershed Approach, the Iowa Flood Center (IFC) has deployed a network of 20 hydrologic network stations to help researchers understand hydrologic conditions in the watershed, allowing them to better analyze and forecast flood and drought conditions. The hydrologic stations measure rainfall and wind speed and direction, as well as soil moisture and temperature conditions. They are co-located with a shallow groundwater well. Data from the stations is collected in real-time and made available on the Iowa Flood Information System.

The staions will help the IFC reach its goal to deploy one station in every county in Iowa. The proposed dense network of about 100 hydrologic stations would help better predict floods, assess droughts, manage water resources, and benefit Iowa’s agricultural producers.
