The Colorado WSC is exploring new methods to calculate real time discharge under the ice which hopefully leads to safer and more accurate data collection. We are also looking at discrete discharge measurement techniques that require only a few holes to be drilled in the ice. Techniques include tracer measurements (i.e. salt dilution), and the PC method which only requires a stage-area rating and few holes drilled around the y-axis to record a maximum instream velocity with a current meter or ADCP, and in this case an upward looking ADVM and streamside edge computing.
