The basin was redesigned after initial model tests indicated the original basin did not contain the hydraulic jump. Two objectives of the model study were to determine the head loss over the stepped spillway and stilling basin and measure the pressure distribution along the stepped spillway, ...

These include water loss surveys to identify the loss (permeable) zones, injectivity test, pressure falloff test, temperature warm up surveys and finally production/flow test. Well discharge analysis should be carried out before the flow testing to assess whether the well will likely to self-...
Hydraulic turbines for energy recovery in wastewater treatment plants, with relatively large discharges values and small head jumps, are usually screw Archimedes or Kaplan types. In the specific case of a small head jump (about 3 m) underlying a rectangu
Keywords: hydraulic jump; submergence; public safety; low-head dams 1. Introduction Dam safety programs focus their attention on preventing loss-of-life associated with failure of dams and the related flooding caused by the uncontrolled release of stored water. High dams and large storage reservoirs...
In an engine failure situation, the last thing you needed was spoiler drag added to engine thrust loss in any maneuver. That was Douglas doing “make do,” as they had done with so many hastily added components on the DC-10. The instrument panel was chaotic, as if they’d just thrown...
It was not a sudden loss of pressure. It happened kinda slowly. I was able to put air back into it and finish the ride. For context, the fork was a cross-country fork (Rock Shox Bluto, based on the Reba chassis) and I was riding a fairly standard descent in Pisgah. Thoug...
“killer dams” or “drowning machines,” of t en present a safety hazard to the public because of their ability to trap victims in a submerged hydraulic jump formed just downstream from the dam. Most of these dams, normally producing vertical water surface drops ranging from one to a dozen...
The submerged hydraulic jump isrnan energy-dissipating underwater jet that can often maintain enough kinetic energy to cause itrnto travel downstream and then rise to the surface as a "boil," with a portion of the water of thernjet flowing back toward the dam. This represents the reverse ...
Using energy dissipaters on the soled aprons downstream of head structures is the main technique for accelerating hydraulic jump formation and dissipating a great amount of the residual harmful kinetic energy occurring downstream of head structures. In this paper, an experimental study was conducted ...
