New system to restore wetlands could reduce massive floods, aid crops

Seed Daily via SPX: Engineers at Oregon State University have developed a new interactive planning tool to create networks of small wetlands in Midwest farmlands, which could help the region prevent massive spring floods and also retain water and mitigate droughts in a warming climate.

The planning approach, which is being developed and tested in a crop-dominated watershed near Indianapolis, is designed to identify the small areas best suited to wetland development, optimize their location and size, and restore a significant portion of the region's historic water storage ability by using only a small fraction of its land. Using this approach, the researchers found they could capture the runoff from 29 percent of a watershed using only 1.5 percent of the entire area.

The need for new approaches to assist farmers and agencies to work together and use science-based methods is becoming critical, experts say. Massive floods and summer droughts have become more common and intense in the Midwest because of climate change and decades of land management that drains water rapidly into rivers via tile drains...
