Abstract: A high level of dissolved oxygen is vital for the maintenance of healthy streams and rivers. Structures in rivers can increase dissolved oxygen levels by creating turbulent conditions where small air bubbles are carried ...

Abstract: Maintenance of a high level of dissolved oxygen is important in natural rivers and in some water treatment processes. This can be enhanced by creating turbulence in the water. One method of producing such turbulence is via ...

Abstract: Various structural measures have been advocated for river restoration and habitat improvement schemes. The W-weir is one such structure that can be used in mobile bed alluvial rivers to diversify habitat and provide grade ...

Abstract: Sediment transport patterns in a meandering channel with instream restoration structures (vane and W-weir) have been studied. Laboratory experiments were conducted in a large-scale mobile-bed channel with graded materials ...

Abstract: The effectiveness of a novel approach of using vanes, installed at a low angle and attached to the bank, for bank protection and for the restoration of river meanders has been investigated in a laboratory study. Experiments ...

Abstract: A numerical study of friction parameters associated with nearly flat tidal channels is reported. Such empirical parameters are often back-calculated using complex flow equations through a procedure referred to as “inverse ...

Abstract: Values of calibration parameters embedded in open-channel flow equations normally are ascertained using observation data that often contains Gaussian noise. These values subsequently suffer from induced errors even if they ...
