Includes bibliographical references (page 12). "This cooperative study with the Water Survey of Canada has resulted in an understanding of new technology and has provided potentially useful data for assessing the winterwater quality of Hamilton Harbour- This first application of the AFFRA to a highly dynamic reversing flow in a ship canal has been evaluated by 40 field experiments using conventional current profiling methods. Significant underestimation of the current and degradation of the data quality over the four month installation period are potential problems for further investigation by the AFFRA manufacturer"--Management perspective.
