This thesis represents an attempt to place such flow measurements on a solid foundation by explaining the theory of water flow through ‘long-throated flumes‘ and their hydraulically related ‘broad-crested weirs‘. On the basis of this theory, and on practical experience, these structures are recommended for use whenever the water surface in the channel at the measuring site can remain free. The thesis concludes with a design procedure that will facilitate the application of these structures. The idea to undertake research on discharge measurement structures was born upon my appointment as the first civil engineer with the International Institute for Land Reclamation and Improve | | 出版日期 | Book 1985 | | 关键词 | Drainage; boundary layer; capacity; control; design; development; energy; flow; history; measurement; model; st | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-6225-5 | | isbn_softcover | 978-94-009-6227-9 | | isbn_ebook | 978-94-009-6225-5 | | copyright | Martinus Nijhoff/Dr W.
