14.1. Measurement Quality Checks
The ADQA evaluates the effect of the data marked invalid on the computed discharge using the total discharge estimated for all invalid ensembles and the discharge estimated in consecutive invalid ensembles.
Good (Green)
Check—No filters exceeded prescribed thresholds.
Caution (Yellow)
Check—Transducer depth (draft) is not consistent for all transects.
Message—Depth: Transducer depth is not consistent among transects.
Check—More than 10 percent of the discharge is interpolated for ensembles with an invalid average depth.
Message—Depth: Interpolated discharge for invalid ensembles in a transect exceeds 10 percent.
Check—More than 3 percent of the discharge is interpolated for consecutive ensembles with an invalid average depth.
Message—Depth: Interpolated discharge for consecutive invalid ensembles exceeds 3 percent.
Warning (Red)
Check—Transducer depth (draft) is less than 0.01 meter.
Message—DEPTH: Transducer depth is too shallow, likely zero.
Check—More than 25 percent of the discharge is interpolated for ensembles with an invalid average depth.
Message—DEPTH: Interpolated discharge for invalid ensembles in a transect exceeds 25 percent.
Check—More than 5 percent of the discharge is interpolated for consecutive ensembles with an invalid average depth.
Message—DEPTH: Interpolated discharge for consecutive invalid ensembles exceeds 5 percent.
