Environmental Hydraulics of Open Channel Flows [PDF]

, 2004
The book is an introduction to the hydraulics of open channel flows. The material is designed for undergraduate students in Civil, Environmental and Hydraulic Engineering. It will be assumed that the students have had an introductory course in fluid mechanics and that they are familiar with the basic principles of fluid mechanics : continuity, momentum,

Flow Hydrodynamic in Open Channels [PDF]

, 2023
Streams and rivers are subject to considerable hydrodynamic loads. Flow interactions with natural or man-made structures in open channels lead to the development of complex dynamic processes, requiring further studies to comprehend fully.

Self-similarity of spanwise rotational motions’ population trends in decelerating open-channel flow

Theoretical and Applied Mechanics Letters, 2022
Decelerating open-channel flow is a type of flow that gradually moves forward with decreasing velocity and increasing water depth. Although all flow parameters change along the streamwise direction, previous studies have revealed that these parameters ...

TRANSIENT FLOW IN A RECTANGULAR OPEN CHANNEL

Journal of Engineering, 2005
In this paper, the transient flow in a rectangular open channel has been studied for different conditions. The velocity and depth of water have been calculated at different sections in the channel. A computer program (Channel) was developed to solve the

Parametric forcing approach to rough-wall turbulent channel flow [PDF]

, 2012
The effects of rough surfaces on turbulent channel flow are modelled by an extra force term in the Navier–Stokes equations. This force term contains two parameters, related to the density and the height of the roughness elements, and a shape function ...

Distribution of motion scales of vortices in turbulent open channel flow

Shui kexue jinzhan, 2015
To understand the distribution of motion scales of vortices in turbulent open channel flow along water depth. A flume experiment system based on high-resolution particle image velocimetry(PIV) was applied to measure fully developed turbulent open channel

Universality of Turbulent Dispersion in a Steady Flow in an Open Channel [PDF]

, 2011
We construct a low-dimensional depth-averaged model of turbulent dispersion of tracers in an open channel flow. Two types of the average velocity profile are considered.
