The problem of low dissolved oxygen (DO) level has been found to be widespread in ice-covered or polluted rivers. This thesis is targeted at providing some fundamental studies on the remediation measure of injecting air/oxygen via existing effluent diffusers to increase river’s DO level, with two...

Understanding the flows inside plunging drop structures could enable efficient ways to transport water between different elevations in urban drainage systems. A physical modelling approach is pursued throughout this thesis to investigate the complex nature of the flow developed inside some of...

Sediment in storm sewers attracts increasing attentions in recent years due to two major issues including the sewer blockage and the environmental contamination. Pollutants attached to fine sediment surface may adversely affect aquatic life and natural water bodies. Excessive sediment deposition...

Three-Dimensional Numerical Investigation on Velocity Field and Mixing Characteristics at Channel Junctions
DownloadFall 2014
Channel confluence is an important component in river systems. The flow dynamics and mixing processes associated with such geometry are highly three-dimensional and complicated. In this study, a commercial software, ANSYS CFX, was employed to investigate the flow structures and mixing...
