Streamflow Measurements Using Salt Dilution Techniques

Salt dilution is a proven method of measuring stream discharge that is widely used around the world but seldom within the U.S. Geological Survey (USGS). This technique is useful at sites where mid-section, ADCP, flume, and volumetric measurement techniques cannot be effectively conducted due to high turbulence, high velocities, and inadequate cross sections.
