A solitary wave by definition moves at a speed faster than the critical flow speed (Christie 1989) and, as a result, move into the supercritical flow upstream of the transition between super- and subcritical flow (Fig.
The studies of Kaya [4] on semi-elliptical side weirs in subcritical flow showed that the discharge coefficient of these weirs is more than classic weirs.
For a subcritical flow [GAMMA] < 1, this corresponds to the characteristics of the real part of natural frequency against flow velocity as normally seen in literature; that is,
Concerning the laminar flow (Re [less than or equal to] 200) and subcritical flow (Re [greater than or equal to] 300) in this study, different proper calculation models are adopted for them, respectively.
[8] presented a dynamic model for subcritical flow analysis in junction of channels.
This study will investigate culverts during subcritical flow (full flow conditions), with air trapped in the flow separation zone at the culvert inlet.
The Froude number remained less than 0.40, indicating subcritical flow even at the design discharge.
For example, if an obstruction, such as a culvert or a weir, is placed in the channel with subcritical flow, a concave water surface called a "backwater curve" develops upstream of the structure.
For this flow problem, the subcritical flow over the same bump has been studied by Goutal and Maurel [28], Zhou [1], and Peng et al.
Fortunate [10] in 1972 developed two correlations for critical and subcritical flow regimes.
Therefore, by applying the preceding considerations and confining the research to subcritical flow, the effect of ([rho.sub.s]/[rho]), and [[V.sub.cc] * (D/[Nu])] can be discounted.
