Manning-type relations do not contain the term viscosity, which limits their use to the field of rough turbulent flow. Strickler roughness coefficient k or n of Manning are estimated with great difficulty, requiring a proven practical experience. In order... see more

The field of rough turbulent flow occupies an important place in the practical applications of hydraulic engineer. It is for this reason that the present study is interested in the most important parameters of this flow namely the characteristic length, t... see more

The rough model method (RMM) is explained through its application to the design of a pressurized pipe-weir, widely used in practice. The three basic equations of turbulent flow are firstly applied to define explicitly the geometric elements of a referenti... see more

The velocity-profile data from NIKURADSE'S (1950) seminal study was reexamined with modern curve-fitting software. A single equation was derived that describes the influence of bottom roughness on the velocity profile over a wide range of flow conditions,... 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

A solitary wave in two-dimensional, incompressible, turbulent free-surface flow over a plane bottom with small, constant slope is considered. The flow is assumed to be slightly supercritical with Froude numbers close to 1. If the flow far upstream and far... 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
