Free-Surface Aeration and Momentum Exchange at a Bottom Outlet [PDF]
, 2007 This study aims to provide some new understanding of the air-water flow properties in high-velocity water jets discharging past an abrupt drop. Such a setup has been little studied to date despite the relevance to bottom outlets.

Teaching Case Studies in Reservoir Siltation and Catchment Erosion [PDF]
, 1998 Waters flowing in streams and rivers have the ability to scour channel beds, to carry particles (heavier than water) and to deposit materials. This phenomenon of sediment transport can affect substantially the design of reservoirs.

Air Entrainment Processes in a Full-Scale Rectangular Dropshaft at Large Flows [PDF]
, 2007 Rectangular dropshafts, commonly used in sewers and storm water systems, are characterised by significant flow aeration. New detailed air-water flow measurements were conducted in a near-full-scale dropshaft at large discharges.

Understanding Air-Water Mass Transfer at Rectangular Dropshafts [PDF]
, 2004 A dropshaft is a vertical structure connecting two channels with different invert elevations. Four configurations of rectangular dropshafts were investigated systematically to study the effects of outflow direction and pool depth on particle residence ...

Nappe Oscillations on Free-Overfall Structures: Experimental Analysis
Journal of Hydraulic Engineering, 2018 AbstractUnder relatively low heads, the occurrence of nappe oscillation, also known as nappe vibration, may be observed on hydraulic structures with a free overfall, such as weirs, crest gates, and...

Numerical simulation of hydraulic performance with free overfall flow
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Recently, free overfall flows have attracted attention of many researchers in the world. It is because the free overfall can be used as a tool in measuring the discharges and flows in any open channel systems or water collection systems for various flow regime at different shape of channels.

Nappe Vibration Mitigation Techniques for Free-overfall Structures
, 2015 Nappe vibration is a phenomenon that has been witnessed in the field for a variety of different free overflow hydraulic structures operating at low heads, such as fountains, crest gates, and weirs. This phenomenon is visually characterized by oscillations in the thin nappe cascading downstream of the control structure.

Brink Depth at Free Overfall – A Review
International Journal of Engineering Research, 2014 The sudden drop of river bed level is known as Free over fall and acts as a control section. Thus it can be used for the estimation of discharge flowing through the river/stream/open channels. The depth of flow just at the free over fall is known as Brink depth or End depth, by measuring which the discharge can be estimated by correlating it with the ...
