Connecticut Natural Gas Corporation (CNG) is a gas distribution utility serving 130,000 customers in Connecticut. Gas purchase costs and pipeline maintenance costs account for 65% of CNG's...
Computer-Assisted Problem Solving in Hydraulic Engineering
A number of practical hydraulic problems may be solved using software that allows interaction at the equation level rather than through higher level languages. This paper presents examples....
Hydro Power Intake Design?Criteria and Experience
This paper briefly addresses parameters to be considered in hydro power intake designs. Included are design approaches and criteria, specific examples, and applicable references. Concerns...
Intakes for Low Head Hydro Plants
The design of hydro intakes is usually based on a desire to achieve low intake losses and an acceptable approach flow distribution to the turbine. Generally, velocities in the intake canal...
Fish Diversion in Hydropower Intake
Hydraulic model studies were conducted to develop a fish screening system to be used in the turbine intakes of Priest Rapids Development on the Columbia River, Washington. The system studied...
Water Supply Intake Structures on Western Rivers
Many of the problems experienced with water supply intake structures on western rivers result from a failure to mitigate the effects of moving sediments. Shallow but varying flow depths...
Vortices at Vertical Intakes
This paper presents the results of an experimental investigation designed to predict the formation of weak, free-surface vortices at vertical intakes with a headrace channel. A weak vortex...
