Rating curves are used to derive river discharge or streamflow from measured river stage time series. However, due to changing environmental conditions such as the presence of ice, sediment, vegetation, or factors, the local hydraulics may change. This means that rating curves or relationships between stage and discharge may need to be adjusted. The “temporary shift” and “override” concepts are used as part of the Water Survey of Canada, WSC, standard operating procedures to accommodate those temporal changes. The animation shows the temporarily shifted rating curve for the calendar year, 1996, and the relationship between stage and reported discharge, as well as in situ measurements of discharge for station 05CK004, Red Deer River near Bindloss, located in the province of Alberta, Canada. This river section is locally a very low-slope river with a large sediment load that is subjected to permanent ice-cover over winter. “Temporary shift” is the dominant technique that is used for discharge adjustment in this station, however, for brief periods when the stage-discharge point departs from the shifted rating curve, the process of “override” is used in which the discharge is further corrected outside the relationship defined by temporary shift and rating curve. Temporary shifts, alongside the practice of override, result in stage-discharge relationships that deviate from base rating curves. Novel and innovative techniques are required for uncertainty quantification due to the spatial and temporal application of temporary shifts per region, and station.
