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...

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...

Evaluation of Two-Stage Outlet Hydraulics
A two-stage detention basin is an effective storm water management tool. This type of basin is designed to control two storm events and it will tend to perform better than a single-stage...

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....

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...

Hydrology for River Management: The Belle River
Crop damages in recent years prompted farmers to back an effort to clean portions of a large inter-county drain. Other groups with conflicting interests pressed for a study of the impact...

Discharge Characteristics of Labyrinth Weirs
The hydraulic performance of labyrinth weirs is developed from data obtained from flume studies and site specific models. Using dimensional analysis, an equation for the discharge is developed...

Pipe Spillway Plunge Pool Design Equations
An equation is given to determine if scour holes will beach and widen excessively. For nonbeaching scour holes, dimensionless equations are given for the progression of scour with time...

Riprap Sizing-Four Methods
A comparison summary is provided for sizing of riprap by four methods: Isbash, Froude, Tractive Force - Logarithmic Velocity Profile (TFL), and Tractive Force - Power Velocity Profile...
