ABSTRACT

PORTER D. 28.08. 1855 Hartford CT/USA 26.02. 1935 Malden MA/USA Dwight Porter graduated from Sheffield Scientific School, Yale University, New Haven CT, obtaining in 1880 the PhB degree. After having served as instructor, he was appointed in 1883 professor of hydraulic engineering at Massachusetts Institute of Technology MIT, Cambridge MA. He was member of the American Society of Civil Engineers ASCE, the Boston Society of Civil Engineers, and the New England’s Water Works Association. Porter’s compendium on stream gagings is almost unknown, despite it was a successful teaching basis. The contents includes Stream gaging, Discharge curves, Gage, Soundings, Water flow, Pulsations, Velocity distribution, Velocity measurement methods, Vertical velocity curves, Velocity at the surface, Mean velocity, Two-point or three-point methods, Rod or tube floats, Integration methods, Harlacher method, Computation of discharge, Discharge curve, Loops, Stout method, Floats, Current meters: Fteley, Price, Haskell, Discharge measurement by chemical means, Slope formulas, Accuracy of stream gagings, Gagings in ice-covered channels, Time required for gagings, Problems. It may be noted that all problems of theoretical and practical hydrometry are addressed in this book. In a later paper it was observed that the channel shape has a significant effect on accurate discharge measurement, and it was recommended that gagings should be made in artificial reaches of a river to eliminate abnormal discharge curves.
