DNR creates new software to track runoff potential

MADISON, Wis. (AP) — The state Department of Natural Resources has developed new software for identifying terrain susceptible to agricultural runoff.

The software, called the erosion vulnerability assessment for agricultural lands tool, or EVAAL, uses topographic data, years of crop data and soil data to create detailed maps of areas where gullies or rills might carry agricultural nutrients away from fields toward water bodies. The software can focus down to three square meters and expand to include an entire watershed.

According to the DNR, the software can help engineers, nutrient management planners, county conservationists, researchers and farmers address pollution.

The software is available for download on the DNR’s website.
