Excerpt from Hydraulics of Rivers, Weirs and Sluices: The Derivation of New and More Accurate Formulae, for Discharge Through Rivers and Canals Obstructed by Weirs, Sluices, Etc;, According to the Principles of Gustav Ritter Von Wex

It seems strange that the earnest efforts of so high a technical authority as Hofrat von Wex should have failed to interest hydraulic engineers the world over. A careful search through the leading hydraulic literature, with one exception, did not reveal a single comment regarding either the man or his work. Prof. I. P. Church says in his "Mechanics of Engineering," 1906 ed., foot of page 688, "Herr Ritter von Wex in his Hydrodynamik derives formulae for weirs, in the establishing of which some rather peculiar views in the mechanics of fluids are advanced."

The unquestioned ability of Hofrat von Wex and his very extensive practical experience along the lines he has treated, place his work in the front rank of technical achievement in the specialty of river hydraulics. His views and theories on this subject, while radically different from those of his time, are most rational and sound, and merit the respect and approval of all practical hydraulic engineers.

With a thorough conviction of the high value of the Wex theories, the author has ventured to place them before his profession in a form which he hopes will prove most practical and acceptable.

The general status of our knowledge respecting hydraulics generally, and particularly the subject of weirs, is very unsatisfactory, to say the least. Hence any progress, if it be real progress, means a radical departure from former conceptions.

It is the rule that new and progressive ideas are received with more or less suspicion, which Professor Church expresses in the word "peculiar." As such ideas become more generally known they receive a more charitable reception and are soon tolerated. When all opposition fails they are crowned by final acceptance. May the present work advance to this final state.
