An ordinary differential equation for velocity distribution and dip-phenomenon in open channel flows
Open channel flows, velocity distribution, dip-phenomenon, ordinary differential equation, semi-analytical solution
2011/8/29
An ordinary differential equation for velocity distribution in open channel flows is presented based on an analysis of the Reynolds-Averaged Navier-Stokes equations and a log-wake modified eddy viscos...
Fuzzy rules based model for solute dispersion in an open channel dead zone
Fuzzy rules based model solute dispersion open channel dead zone
2009/12/4
A method has been developed to estimate turbulent dispersion based on fuzzy rules that use local transverse velocity shears to predict turbulent velocity fluctuations. Turbulence measurements of flow ...
THREE-DIMENSIONAL STABILITY ANALYSIS OF OPEN CHANNEL FLOW OVER AN ERODIBLE BED
THREE-DIMENSIONAL STABILITY ANALYSIS OPEN CHANNEL FLOW ERODIBLE BED
2009/10/29
The formation oP ripples and dunes (lower range bed waves) is assumed to
be related to the transport of sediment as bed load. From the present
theory it is concluded that the formation of the upper ...
Investigation of the Friction Coefficient in Smooth Open Channel Flows
Open channel energy loss friction factor
2009/10/14
In practical engineering, the friction coecient formulations developed for circular pipes are usually assumed to be valid for open channels and used in derivation of mathematical formulation. However...
Study of Aeration Performance of Open Channel Chutes Equipped with a Flip Bucket
Aeration eciency Chute Dissolved oxygen Flip bucket Open channel Oxygen transfer
2009/10/12
An adequate supply of dissolved oxygen (DO) is essential for the survival of aquatic organisms. Hydraulic structures can increase DO levels by creating turbulent conditions where small air bubbles are...
Effects of groundwater flux on open-channel estimates of stream metabolism
groundwater flux open-channel estimates stream metabolism
2014/5/26
The open-channel oxygen method can produce precise estimates of photosynthesis (P) and respiration (R) over a wide range of stream conditions. It is widely recognized that flux of groundwater contribu...
