Iowa Learning Farms is hosting a free virtual field day on the challenges of improving water quality and quantity management in the karst topography of the Upper Iowa Watershed at 1 p.m. Feb. 4.
Matt Frana, Upper Iowa Watershed project coordinator, and Winneshiek County landowners Tom and Maren Beard will be participate in the discussion.
“The karst topography in northeast Iowa creates some unique challenges when planning for water detention project sites,” Frana says. “Shallow depth to bedrock, easily dissolvable bedrock, highly fractured bedrock, and sinkholes can become problematic if water is pooled above or near them.”
“By reviewing soils, bedrock, sinkhole and terrain GIS map layers, high-risk areas can be identified and avoided without wasting time on lengthy and costly in-field investigations,” Frana adds. “If a site appears to have a moderate risk, methods like soil or bedrock boring and the use of electrical resistivity imagery can be used to determine if potentially problematic conditions exist below the surface as part of the planning process to better assure successful projects.”
