Iowa Flood Center Deploys Rain Gauges

IFC researchers have designed and installed 20 state-of-the-art rain gauges with soil moisture probes in the Turkey River watershed in northeast Iowa, with a few more gauges in the South Fork of the Iowa River watershed (Franklin, Hamilton, and Hardin counties) and the Walnut Creek watershed (Jasper County).

IFloodS: NPOL Radar on the Ground

NASA and Iowa Flood Center staff have been busy deploying instrumentation to field locations in the Cedar, Iowa, and Turkey River watersheds in preparation for the campaign.

Flood Damage Reduction in Soap Creek

Iowa Flood Center researchers will provide an update on the Iowa Watersheds Project and share results of their work including the impact the built structures in Soap Creek have had on reducing flow and flood damages in the watershed.
