International symposium on hydrometry

Approximately 520 engineers and scientists from 55 countries attended the International Symposium on Hydrometry held at Koblenz, Federal Republic of Germany, from September 13 through 22, 1970. The symposium was convened by Unesco and organized in cooperation with the World Meteorological Organizations (WMO), Unesco, the National Committee for the International Hydrological Decade of the Federal Republic of Germany, and the International Association of Scientific Hydrology (IASH). The symposium was organized within the framework of the International Hydrological Decade (IHD). After a welcoming speech by J. Wallner, Chairman of the Organizing Committee, the opening address was presented by S. Dumitrescu, the representative of Unesco. Introductory statements were then delivered by T. Palas, the representative of WMO; by L.J. Tison, the representative of IASH; and by K. Wittock, the representative of the Government of the Federal Republic of Germany.

Development of a standard rating for the Price pygmy current meter

Fifty new Price pygmy current meters, 50 used Price pygmy meters with used rotors, 50 used Price pygmy meters with new rotors, and 26 used Price pygmy meters with straight uniform (nonbeaded) contact wires were rated individually in a towing tank. A standard rating of V =0.961 N +0.039 ( V =0.293 N +0.012), where V is the velocity in feet per second (metres per second) and N is the meter rotation in revolutions per second, was established for the group of new meters. Repeated ratings of two new meters showed that under the best rating conditions, the individual Price pygmy rating is repeatable to within 1 percent. The standard errors of velocities predicted using the individual ratings and the standard ratings were compared. The use of the standard rating resulted in statistically higher standard errors than the individual ratings for all groups of meters. However, the differences are a fraction of 1 percent higher and are not of concern for practical purposes. The individual ratings and standard rating for the used meters with new straight contact wires were found to be statistically similar to the ratings for the new meters. Continuation of the use of individual ratings of Price pygmy current meters is probably unnecessary with the implementation of precise standards in their manufacture, rating of a random sample, and use.

Measurement of discharge by the moving-boat method

This chapter describes the procedures for measuring discharge in large streams by the moving-boat technique. During the traverse of a boat across a stream, a sonic sounder records the geometry of the cross section, and a continuously operating current meter senses the combined stream and boat velocities. These data are converted to discharge for the cross section quickly, efficiently, and inexpensively. Measurements obtained by the moving-boat technique compare within 5 percent of measurements obtained by conventional means. Field and office procedures applicable to this method are outlined. Theory of technique is developed and equipment required is described. Selection and preparation of the cross section is detailed. A complete facsimile example of computation of a moving-boat measurement is given, and the determination and application of adjustment factors are described.

Systems for monitoring and digitally recording water-quality parameters

Digital recording of water-quality parameters is a link in the automated data collection and processing system of the U.S. Geological Survey. The monitoring and digital recording systems adopted by the Geological Survey, while punching all measurements on a standard paper tape, provide a choice of compatible components to construct a system to meet specific physical problems and data needs. As many as 10 parameters can be recorded by an Instrument, with the only limiting criterion being that measurements are expressed as electrical signals.
