Analysis of the influence of ferricrete on hyporheic exchange flows
The area of confluence between surface water and groundwater, known as the hyporheic zone, is a natural biogeochemical filter that is dependent on channel morphology and hydraulic conductivity, pressure-driven downwelling and upwelling currents, and stream discharge. In Cement Creek near Silverton, Colorado, deposition of amorphous iron minerals reduces the permeability of the streambed and limits flow through the hyporheic zone. This limited exchange may lower the potential for pollutant attenuation from the metals-loaded waters of Cement Creek within the hyporheic zone. This study found that ...
