![]() Henceforth, equations applicable for both free flow and submerged flow regime are proposed and hence producing Ditchrider's table for field implementation of the flume. The US Parshall flume was originally developed for accurate flow measurement for irrigation channels, where a channel and / or structure is not clearly defined. Free flow and submerged flow calibration are done within the flow range of 0. From the literature study very few, in fact no data are available for 5? throat width for any flume length. Parshall Flumes, created by Parshall (1928). In the present study, a series of detailed laboratory measurements are made under steady-state flow conditions through a Parshall flume of throat width 0. One of the most commonly used flumes which can accurately measure the water flow is. Since 1922, the Parshall Flume has been the most widely used type of flume for fixed flow monitoring installations. The advantages of this structure include minimal head loss, low construction cost, adaptability to a variety of channel types, and ability to measure wide ranges of flows with custom-designed structures. Keywords: Flume, Parshall flume, free flow, submerged flowĪbstract: In the flow measuring structures with control section such as Parshall flumes, a relationship would be produced between water depth and discharge.
