Freeboard Allowances for Chute Spillways
Allowances must be made for the physical phenomena which cannot be modelled, such as wave action, air bulking, splash and spray; the simplifications of behaviour implicit in the calculations;...
Hydraulic Model Studies - Sidney A. Murray Jr., Hydroelectric Plant
The power plant is located at the Old River Control of the Lower Mississippi River (Louisiana). It consists of an intake channel about 5000 ft long, a power plant with eight bulb units...
Physical Model Study of New York State Dam
The New York State Dam is located on the Mohawk River near its confluence with the Hudson River. Downstream from the dam, the river flow is divided into six channels as the water passes...
Hydraulic Model Tests of Flow around Penstock Suspended inside the Tunnel for Design of a Small Hydro
The proposed hydropower project in the State of Virginia involves design and construction of a steel penstock hung from the crown of an existing outlet tunnel at this U.S. Army Corps of...
Spillway Crest Development through Model Testing on Chenderoh Ambursen Dam
The Chenderoh Hydroelectric Project on the Perak River in Malaysia was placed in service in 1930. The hollow Ambursen dam was modified in 1944 by the additions of a concrete cap with flashboards....
