Abstract: A low velocity current meter using optical tracing of hydrogen bubbles is described. The instrument was developed for applications in hydraulic laboratory studies. Its design and operational characteristics are given. The ...

Abstract: A negatively buoyant inflow to a lake or reservoir sinks to the bottom and forms an underflow. In this process, the “plunging flow” entrains ambient water and becomes diluted. The dilution alters the buoyancy and hence the ...

Abstract: Water temperature profiles were measured at 2‐min intervals in a stratified temperate lake with a surface area of

Abstract: A research program was conducted at the St. Anthony Falls Laboratory to investigate impulse pressures caused by the collapse of transient cavitation bubbles. The impulsive pressures associated with vibratory as well as ...

Abstract: The internal flow behavior of negatively buoyant flow in a diverging horizontal channel is inferred from visual observations and temperature distribution. Some observed flow features are explained and illustrated.

Abstract: Negatively buoyant (plunging) flow entering a horizontal and diverging channel has been studied in the laboratory. Such flow is found at the heads of reservoirs and near effluent sites into lakes. Six flow regimes could ...
