This study examined whether electromagnetic induction is a reliable tool to predict various streambed properties, including water conductivity, water temperature, and hydraulic conductivity. The test site was along the North Loup River, outside of St. Paul, Nebraska. Electromagnetic induction was performed using a field portable, multi-frequency EMI tool. Hydraulic conductivity was measured using the falling-head permeameter test, and water temperature and conductivity were measured using handheld meters. The study found that there is a strong positive correlation between water conductivity and apparent electrical conductivity measured by electromagnetic induction. This relationship can be explored further through the analysis of spatial patterns …
