Numerical Modeling of Flow in Hydropower Intakes
To reduce high mortality of downstream migrating juvenile salmon at hydraulic turbines, traveling screens are used to guide the juveniles into a bypass channel for safe passage. However,...
Water and Sediment Movement in Irrigation Furrows
Water movement in an irrigation furrow is simulated by numerically solving the governing equations of continuity and momentum for unsteady, spacially varied flow in a pervious bed open...
Hydraulic Testing of a Large Make-Up Pipeline
A 37 mile pipeline which consists of sections of 114 inch, 96 inch and 66 inch pipes was constructed for delivering secondary sewage effluents for power plant makeup. During initial operations,...
Coping with High and Low Pressures of Transient Flow
Conditions exist in most long distance water pipelines, such that abnormal but inevitable occurrences will cause transient flow. Often the most crucial conditions for consideration by...
Hydraulic Analysis of Water Transmission Flowing Party Full
The hydraulic behavior of a transmission line that flows full along only part of its length is more difficult to analyze than a completely full line. Unsteady open-channel and closed-conduit...
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...
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...
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...
Local Scour at Fish Rocks
There is a growing interest in the enhancement of rearing habitat for juvenile anadromous fish in the Pacific Northwest. This has focused attention on the need for a better understanding...
Modeling Multiple Spur Schemes to Control Bank Erosion
A natural consequence of the meandering tendencies characteristic of all streams, is streambank erosion. The problem has taken on particular interest recently, focusing on erosion problems...
Willamette River Adjustments to New Spur Dikes
Severe bank erosion has caused recent local losses of up to 30 ft (9 m) per year of prime agricultural land along a half-mile (800 m) reach of the Willamette River, Oregon. The U. S. Army...
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...
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...
Safety, Maintenance, and Aesthetic Considerations Associated with Outlet Control Structures for Stormwater Detention Ponds
Findings of the Task Committee for the Design of Outlet Control Structures, an ASCE Technical Committee, regarding maintenance, safety and aesthetic considerations for stormwater detention...
Design Accuracy of Stormwater Detention Basins
While the stormwater detention basin is the most frequently used method for controlling runoff from developing areas in the United States, there appears to be no statement of the probable...
