Errors in Piezometric Measurement
Laboratory tests indicate that piezometric measurements of depth in open channels are characterized by positive errors that increase with size of piezometer opening. For a given piezometer size, the error is expressed as a constant percentage of the mean velocity head. Roughnesses added to the test channel tended to reduce the magnitude of the error whereas surface waves did not affect the piezometric measurement.
