Examples of short-throated flumes are Parshall flumes and H-flumes, throatless flume with rounded transition and throatless flume with broken plane transition (cutthroat flumes). When compared with weirs, long-throated flumes are similar to broad-crested weirs (parallel streamlines), while short-throated flumes behave like short-crested weirs Author: Adeniyi Adeogun, Abdul Rasak Apalando Mohammed. , , and (which all deal with broad-crested weirs and long-throated flumes); in Sections , , and ; and in Annex 4. Minor classifications have been added and errors corrected. Further, the typeface and lay-out have been changed to improve the legibility of the text and accomodate some additional information.
This guide covers recommendations for the selection of weirs and flumes for the measurement of the volumetric flow rate of water and wastewater in open channels under a variety of field conditions. This guide emphasizes the weirs and flumes for which ASTM standards are available, namely, thin-plate weirs, broad-crested weirs, Parshall flumes, and Palmer-Bowlus (and other long-throated. Field observations and measurements support these laboratory results, which should apply to most long‐throated flumes, since a rectangular broad‐crested weir represents the .
Computer calibrations of broad-crested weirs use the same principles and theories developed for long-throated flumes (see Section ). FLUMES A flume is an artificial open channel constructed to contain flow within a designed cross section and length (Brooks et al, ). Long-Throated Flumes and Broad-Crested Weirs In the context of water management, structures that measure the flow rate in open channels are used for a variety of purposes: (i) In hydrology, they measure the discharge from catchments; (ii) In irrigation, they measure and control the distribution Pages:

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'.

while long-throated flumes are well adapted to natural streams. The range of potential applications for the family of long-throated flumes and broad-crested weirs is unlimited, both in terms of channel types and ranges of flow rates. The primary advantage of these flumes and weirs is the theoretical predictability of.
Long-throated flumes and broad-crested weirs provide a practical, low-cost, flexible means of measuring open-channel flows in new and existing irrigation systems, with distinct advantages over. Long-throated flumes and broad-crested weirs have become accepted standards for open-channel flow measurement during the past two decades.
These structures offer the accuracy and reliability of. Some of the work is compared to results from the WinFlume computer program (Wahl et al. ) developed by the discussers for the calibration and design of long-throated flumes and broad-crested weirs.
Many of the results presented by the authors touch upon subjects previously investigated and documented in detail by the discussers and others. Parshall and Cutthroat flumes require upstream ponding depths of about 40% of the head reading while long-throated flumes and the re lated broad-crested weirs require about 10% to 15%.
The vertically adjustable, long-throated flumes allow the reduction of ponding at nearly all flow rates for a Author: John Replogle, Brian Wahlin.

Long-throated flumes and broad-crested weirs: M.G. Bos. Martinus Nijhoff/Dr. Junk Publishers, Dordrecht, The Netherlands, xiii + pp., Dfl/US$ Abstract.
This book discusses the measurement of open channel flows on a solid scientific foundation by developing sound theory of water flow through long-throated flumes in their numerous shapes (including broad-crested weirs) and facilitates the selection of suitable measuring structures.
Long-throated flumes and broad-crested weirs provide a practical, low-cost, flexible means of measuring open-channel flows in new and existing irrigation systems, with distinct advantages over other flume and weir devices.
A primary advantage is the fact that these structures can be custom-designed and calibrated with a computer program based on well-established hydraulic by: crested weirs with a streamlined flow contraction also fall into the long-throated flume family.
Broad-crested weirs are particularly well adapted to irrigation canals. Flumes are better adapted to natural streams. The application of this family of long-throated flumes and broad-crested weirs is unlimited.
