Freezing and Thawing of Soil-Water Systems
This book presents a state-of-the-practice review on freezing and thawing of soil-water systems through ten interrelated papers on this subject. The papers review the following topics:...
Stormwater Detention Outlet Control Structures
The Hydraulics Division's Task Committee for the Design of Stormwater Detention Outlet Control Structures was formed to review and report on the state-of-the-art of stormwater...
Watertightness and Seepage Control in Roller Compacted Concrete Dams
An unjointed mass of roller compacted concrete (RCC) can easily be proportioned and compacted so that it is essentially impermeable and 'watertight. ' Permeability tests of various field-placed...
Emerging Computer Techniques in Stormwater and Flood Management
These proceedings identify and assemble information on recent applications of mini- and microcomputer technology to problems in urban stormwater and flood management. Instrumentation and...
New Plant Treats River and Well Water
A new 16 mgd water softening plant at Elgin, Ill. is designed to treat raw water either from the Fox River or deep wells, or in any combination. Flexibility of the chemical feed systems...
Pipeline Hydraulic Transient and Leak Detection Analysis
Liquid and gas pipelines cannot be properly designed with consideration of steady flow analysis techniques alone due to the possibility of pipeline failure resulting from uncontrolled...
Logan Airport Re-Visited
The first detailed evaluation of self-weight consolidation of a large hydraulic clay fill was performed during the construction of Logan Airport in Boston nearly 40 years ago. The paper...
Water for Resource Development
The primary goal of these proceedings is to provide an awareness of the many areas of resource development in which hydraulic engineering plays a key role. The papers cover a variety of...
Grouting Rehabs Earth Dam
To accommodate increased storage needs the Pennsylvania Power & Light Company had to reactivate a fly ash basin and raise an adjacent embankment dam. However, seepage through the...
Thalweg Disposal: Demonstration of an Alternative
Disposal of dredged material in the main channel, or thalweg, is an alternative disposal option for maintenance dredging. The material dredged from the Upper Mississippi River is clean...
Offshore Dredging - Is it still Cost Effective for Beach Restoration?
Offshore dredging has been the source of sand for beach restoration in southeast Florida since Broward County constructed the first project in Pompano Beach in 1970. However, with increasing...
Design and Construction - Theodore Ship Channel
Environmental impacts, greater technological capabilities, and improved evaluation techniques make the disposal of large quantities of dredge material more complex and involved. Also,...
Open Water Disposal for Marsh Creation James River, VA
There is a need for close cooperation between design and construction of levees on soft foundation for containing dredge material. The scope of this study included marine exploration,...
Turbidity Generated by a Model Cutterhead Dredge
The study of turbidity generation indicates that, in general, turbidity increases with an increase in the cutter speed and an increase in the cutter swing velocity. A silt curtain deployed...
Dredge Automation: The State-of-the-Art
Automated control systems are being developed and applied to enhance the productivity and cost-effectiveness of dredges. Referring particularly to hydraulic type dredging plants, the functions...
Development of the Dredging Wheel
The 'bucket line' dredge and 'cutter suction' dredge are two distinct types of equipment. The cutter suction system has developed more...
Selecting a Dredge Pump
While it is not necessary for the dredge operator to know how to design a dredge pump, the ability to select one that meets his project requirements is essential to insure the success...
Dredge Cutterhead Flow Processes
Feasibility studies of new dredge intake and cutterhead shielding techniques were conducted to improve hydraulic cutterhead dredge performance. Simple modification of the suction mouth...
Dredging-Related Considerations in Navigation Channel Design
In the design of a navigation project, the channel depth, width, and alignment for a given set of navigation requirements are dependent on physical, hydrodynamic, and sedimentological...
Influence of Roughness on Velocity and Dispersion at Low Flow
Dependence of the hydraulic and transport characteristics of low flow on channel roughness is investigated. Empirical expressions are used to estimate roughness coefficient as a function...
