The channel locations were instrumented with Orion bromide selective electrodes to monitor instream bromide concentrations and guide the collection of physical samples. Physical samples were collected at irregular time intervals weighted to cover the rising and falling limbs more intensively than other time periods. The table below contains the solute injection parameters.
All distances are relative to the established river markings.
