Excerpt from Current Meters: For Use in River Gauging The Committee on Gauging Rivers and Tidal Currents was appointed by the Department to prepare a conspectus of information available as to the methods and appliances which have been used in investigations bearing upon measurements of river flow or of tidal and other currents, and a to the arrangements for the testing and standardising of such apparatus, and to test such appliances as appear to be suitable for use in the study of the water power resources of this country. The following report has been prepared by Dr. M. A. Hogan on the instructions of the Committee, and is intended to bring together in a summarised form the information available as to the conditions affecting the design and use of current meters, and to give a description of those types now in use. A bibliography of the more recent literature on the subject which is available in the principal London libraries has been prepared. In view of the cost involved, it was not considered worth while printing this bibliography, but type-written copies have been deposited with those libraries likely to be interested. A shorter bibliography of the literature dealing with current meters is included in this publication. While preparing this report Dr. Hogan visited France and Switzerland. The Department is indebted to the Chief Engineers and other officials of the Service des Forces Hydrauliques (France) and of the Service des Eaux (Switzerland) for the information supplied and for the kindness and courtesy they extended to Dr. Hogan.
