Preliminary evaluation of the floating dome method of measuring reaeration rates
The floating dome method of measuring reaeration rates was evaluated using a modified tracer technique and a disturbed equilibrium technique. The lack of agreement between results of the floating dome method and the other methods was attributed to limitations in instrument accuracy amplified by physical relationships of the dome to the water column rather than conceptual errors in the dome method. In techniques where polarographic oxygen probes are used to monitor the oxygen content within the dome atmosphere, the ratio of volume of the dome to volume of the water column under the dome must be kept below 0.02 to minimize instrument error to less than 10 percent of the predicted oxygen transport. The combination of instrument limitations, coupled with environmental limitations caused by wind and the greenhouse effects, severely restrict application of the floating dome method.
