RISUpstream Hydraulics of a Run-of-the River Hydropower Facility for Fish Entrainment Risk Assessment
Publisher: American Society of Civil Engineers
Abstract: Run-of-the-river hydropower is a typical form of power generation in mountainous regions. This study investigates the velocity field upstream of Aberfeldie dam, a run-of-the river facility on the Bull River near Wardner, ...

Dissipation of Supersaturated Total Dissolved Gases in the Intermediate Mixing Zone of a Regulated River
Publisher: American Society of Civil Engineers
Abstract: In regulated rivers downstream of hydropower facilities, understanding how supersaturated total dissolved gases (TDGs) are distributed and dissipated is crucial, as they can negatively impact the aquatic environment. The ...
Generation of Supersaturated Total Dissolved Gases from Low-Level Outlets at Hydropower Facilities
Publisher: ASCE
Abstract: Supersaturated total dissolved gases (TDGs) generated by dams can cause gas bubble trauma and mortality in fish in downstream waters. In this study, we evaluated air entrainment and generation of supersaturated TDG at two ...
Case Study of Total Dissolved Gas Transfer and Degasification in a Prototype Ski-Jump Spillway
Publisher: ASCE
Abstract: Gas transfer in dam spillways often leads to supersaturation of total dissolved gases (TDGs) that can cause fish mortality. Quantifying TDG associated with this process is crucial in the development of operating alternatives ...
