Short-throated flumes The term 'Short-throated flumes' as it applies to the area of reclamation can be defined as ' Short-throated flumes are considered short because they control flow in a region that produces curvilinear flow. While they may be termed shortthroated, the overall specified length of the finished structure, including transitions, may be relatively long. The Parshall flume is the main example of this kind of flume. These flumes would require detailed accuracy and accurate knowledge of the individual streamline curvatures for calculated ratings which is usually considered impractical. Thus short-throated flumes are determined empirically by comparison with other more precise and accurate water measuring systems'.
