The present knowledge on the behavior of hydraulic jumps is only for smooth, horizontal channel beds. Very limited studies have been reported in the literature on the performance of hydraulic jumps on rough beds.The objective of our study is to investigat... see more

The dimensioning of the channels and especially the computation of normal depth plays a significant role in the practice of hydraulic engineer. The classical methods usually used are graphical or iterative to determine the linear dimensions of a pipe or a... see more

This paper reviews the applicability of nine selected expressions in determining the equivalent value of the Manning coefficient of roughness. For this purpose, a prismatic 4m-long and 0.05m-wide trapezoidal-shape channel was constructed, namely the homog... see more

Designing and maintaining open channels as well as studying nonuniform flow crucially depend on normal depth. In practical applications, the vaulted rectangular cross-section is widely applied. However, the form of the relationship determining the normal ... see more

The study proposes to establish the relation which governs the Manning’s n roughness coefficient in a trapezoidal-shaped channel. It appears that n depends on the depth of the flow, the bottom width of the channel, the slope of the channel, the absolute r... see more

Numerous studies have been and are still being carried out on flows in periodic pattern channels. However, if these continue to multiply, it is because the phenomena involved are very complex and there are still a large number of poorly described points. ... see more

The objective of this work is to propose a new approach to the calculation of the linear dimension of a rectangular channel at critical flow, whose internal walls are characterized by the relative roughness . The calculation takes into account the effect ... see more

Normal depth plays a significant role in the design of open channels and in the analysis of the non-uniform flow as well. Currently, there is no analytical met hod for calculation of the normal depth in open channels, including the trapezoidal profile. Cu... see more
