River gauging structures called weirs force the river generate this hydraulic drop as the water falls from a stilling pool, while flumes normally use a constriction to generate the hydraulic drop. There are many types of weirs from V-notch (Figure 3) to rectangular thin-plate to Crump weirs, and many types of flumes from trapezoidal (Figure 4. The book is the outgrowth of the lecture notes that I prepared for the four-creditcourse Electrodynamicsthat was introduced in the into electrodynamics, the electromagnetic potentials, gauge transformations, covariant formulation of classical electrodynamics, force, momentum and en-. PREFACE TO THE PRESENT EDITION The present book titled, Electromagnetics: General theory of the electromagnetic field. Classical and relativistic approaches, is an extended form of the previous two editions of the books titled Electromagnetics: General theory of the electromagnetic field. The new book, at the difference of the previous ones, contains four new appendices. Discharge measurements are made from boats where no gauging cableways or suitable bridges are available and the river is too deep to wade. The boat is held in place in the measuring section either by fixing to a cable strung across the river (the boat/cableway method) or .

Electromagnetic Flow Measurement. Flow data from electromagnetic gauging stations may also be computed on-site. The technique requires the measurement of the electromotive force (emf) induced in flowing water as it cuts a vertical magnetic field generated by means of a large coil buried beneath the river bed or constructed above it.   25 Design and installation of ultrasonic and electromagnetic flow gauging stations DAVE GIBBARD Peek Measurement Ltd, Kingsworthy, Winchester, Hants 7QA, UK The paper describes the ultrasonic and electromagnetic methods of river flow measurement and provides examples of existing installations in the United Kingdom.

Previous article in .   The Environment Agency of England and Wales owns and operates over 1, river flow gauges of which 35 are electromagnetic (EM) river flow gauges. The Environment Agency became fully operational in and is a non departmental government body whose principal aim is to protect and improve the environment and in doing so contribute to.
