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.

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 ...

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.

Unsteady Flow Patterns between Two Egg-Carton Corrugated Plates
Engineering Transactions, 2021 Unsteady analyses of the flow between two egg-carton corrugated plates were performed. Geometry effects on the flow were as follows: “closed recirculations” shrank downstream the channel and became “open recirculations”.

Numerical simulation of flow over a rough bed [PDF]
, 2007 This paper presents results of a direct numerical simulation (DNS) of turbulent flow over the rough bed of an open channel. We consider a hexagonal arrangement of spheres on the channel bed.

Effect of near‐bed turbulence on chronic detachment of epilithic biofilm: Experimental and modeling approaches. [PDF]
, 2010 The biomass dynamics of epilithic biofilm, a collective term for a complex microorganism community that grows on gravel bed rivers, was investigated by coupling experimental and numerical approaches focusing on epilithic biofilm‐flow interactions.

Modeling and Analysis of Fluid Flow through A Non-Prismatic Open Channel with Application to Drilling [PDF]
Modeling, Identification and Control, 2018 This paper presents the development and validation of a simplified dynamic model of a Venturi channel. The existing dynamic models on open channels are based on the open channel flow principles, which are the shallow water equations.
