Dredging Developments in the Canadian Arctic
The use of dredges in the Canadian Arctic in connection with oil exploration programmes has lead to the adaptation of existing and adoption of new techniques. Further development is required...
An Offshore Mound Constructed of Dredged Material
The concept of using dredged material to intentionally construct an underwater mound was tested and confirmed at the Dam Neck Disposal Site, 4 miles offshore Virginia Beach, Virginia....
Hydraulic Uncertainty in Risk Analysis
Considerable effort has been expended in defining and evaluating hydrologic uncertainties; however, the analysis and evaluation of hydraulic uncertainties has received little attention....
Dynamic Reliability Models for Hydraulic Structures
In addition to the determination of capacity and layout of hydraulic structures under normal design, one other important but related task that faces engineers is the evaluation of reliability....
Reliability Analysis as Reflected from the Fourth International Symposium on Stochastic Hydraulics
Reliability analysis is perhaps one of the most practically important branches of the general field of stochastic hydraulics. Its potential applications include quantitative evaluation...
Upper Hudson River Valley Dam Break Model
In order to determine areas of inundation due to the failure of Conklingville Dam, a dam break analysis was performed, and the resulting outflow hydrograph was routed through the downstream...
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...
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...
Hydrotest Rupture of Penstuck Liner at Bath County
Bath County is the construction site of Virginia Electric and Power Company's pumped storage project. Rupture of a penstock liner during hydrotest at high pressure threatened...
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...
Flow and Scour Patterns around Gabion Structures
There is a need for simple, inexpensive and effective means for streambank protection and fish habitat enhancement. Initial results are presented of laboratory research on the performance...
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....
