Stability of Method of Characteristics
For the analysis of waterhammer, the first-order accurate method of characteristics (MOC) has been widely used for which Courant condition for stability has been developed neglecting the...
Computer Aided Hydraulic Design of Pipelines
General purpose computer software packages are being used more frequently in the hydraulic design of pipeline systems. The areas where the use of such packages are advantageous over earlier...
Vacuum Assisted Pipelines Operation
In the process of upgrading the sewerage facilities for Lancaster, Pennsylvania, it was decided to combine two existing facilities into one new facility. This required the design of three...
Milwaukee Sewerage District Interplant Pipeline
The pipeline is intended to transfer solids between the Jones Island and South Shore treatment works a distance of approximately 12 miles (19. 3 km). The 4 conduit pipeline comprising...
The Design and Construction of the Bartletts Ferry Labyrinth Weir Spillway
The discharge capacity of the Bartletts Ferry Project has been increased 165 percent by the addition of a labyrinth weir spillway. The hydraulic design was based on a published design...
Instruments Detect Dam Movement During Construction
Recent attention has been given to retrofitting electrical generation facilities at existing dams. Maintaining a safe structure during construction, and accomplishing this within a budget...
Valuable Design Insights Derived from Construction and Operation of Kinzua Dam
A number of design alternatives have surfaced during more than 17 years of operating experience at Kinzua Dam which should be useful in the design, construction, and operation of other...
A Nebraska Power District's Experience in Stabilizing by Silt Injection
The structures, rolled earth and concrete, of the Central Nebraska Project are constructed on foundations of loessial soils that range from a few feet to more than 100 feet in depth. The...
Numerical Modeling of Downstream Impacts Resulting from Hydropower Operations
Hydropower peaking operations often have downstream impacts that require an accurate assessment. A one-dimensional implicit finite difference numerical model has been used to accurately...
Intake-Shoaling and Pump-Vibration Problems
Iowa Generation's Council Bluffs Unit 3 circulating water-intake structure has experienced two major problems: (1) formation of sand bars in front of the trash racks during...
Operating Experience--Fine-Mesh Traveling Screens
Start-up and operating results for a new screenhouse at the Prairie Island Nuclear Generating Plant, 50 miles (80 km) downstream from Minneapolis/St. Paul, are compared to design assumptions....
Passive-Intake System for a Shallow Sand-Bed River
The Jeffrey Energy Center draws its cooling water make-up from the Kansas River near Belvue, Kansas. At this site, the Kansas River is a shallow sand-bed river of constantly changing bottom...
Japanese Experience with Intake Designs
To diversify its power sources, Japan has operating or under construction some 37 nuclear power units. This technology and the design criteria are imported from the U. S. The power plants...
Design of Selective Withdrawal Intake Structures
An overview is presented of the general methodology used by the U. S. Army Corps of Engineers in the design of selective withdrawal intake structures. Considered are the types of structures...
Report on Task Committee's Scope and Findings
A Task Committee for the Design of Outlet Control structures studied the state-of-the-art practices concerning the hydraulic function, water quality, public safety, maintenance and aesthetic...
Outlet Hydraulics vs. Storage Requirements
In many cases developers must use a portion of their land for temporary detention of storm runoff in order to comply with local ordinances. A simple method is outlined which yields the...
Detention Pond Outlet Design for Pollution Control
Stormwater runoff detention ponds were originally developed for the control of flooding and the designs of the outlet control structure must be modified to obtain pollution control objectives....
High Streamflow Behaviors in the Ohio River Basin
The intensity function, which describes the severity of the flood occurrences, is a critical factor in flood control and reservoir operation. It is found that the occurrence rates of high...
A Three Dimensional Hydraulic Jump
A study is conducted to define the three-dimensional hydraulic jump that occurs in a rectangular channel downstream of a rectangular contracted sluice gate. A sequent depth ratio equation...
Reservoir System Management for Water Quality
A reservoir system analysis computer model has been recently developed with the capability to simulate up to 10 reservoirs, 30 control points and 8 water quality parameters. With this...
