WinFlume - Windows-based software for the design of long-throated measuring flumes

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 theory. This allows the design of structures that meet unique operational and site requirements, and eliminates the need for laboratory calibration. To facilitate future use of these devices, the Bureau of Reclamation and the Agricultural Research Service have recently developed the Windows-based, WinFlume computer program described in this paper.
