"February 1989." Includes bibliographical references. "A series of tests was conducted to examine the performance of the towing carriage at the Hydraulics Laboratory of the National Water Research Institute (NWRI), Burlington, Ontario. The results show that the mean speed is accurate to within 0.13% at the 99%confidence level. Comparison with tests conducted in 1982 showed that there has been some deterioration in the performance of the carriage in the upper speed range. Although the apparent deterioration of performance is not excessive it suggests that some overhauling of the system's components is indicated. Recommendations are made for the implementation of a monitoring program to document any further changes in the performance of the towing carriage"--Abstract.
