Instrumentation Performance in Soft Clay Soils (A Case History)
In 1978, IDEAL BASIC INDUSTRIES, INC. initiated construction of a cement manufacturing plant located south of Mobile, Alabama on the Theodore Ship Channel. Because deltaic clays were too...
Waste Phosphatic Clay Disposal in Mine Cutsr
Research was undertaken to assess the applicability of waste clay disposal back into phosphate mine cuts. The pit was monitored for two years with measurements of clay surface elevation,...
New Tools Help Find Flaws
Certain electromagnetic tools for nondestructive evaluation of existing infrastructure, though not widely used, can cut cost and time of identifying flaws in existing infrastructure. Five...
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...
Draghead Designs vs. Production
This paper discusses the development and design of draghead configurations for silt materials and describes a testing program designed to determine the most efficient range of the controllable...
Evapoconsolidation in Fine-grained Material
The increased difficulty of obtaining land needed for confined disposal of dredged material and phosphatic clays highlights the need to assess alternative disposal measures by accurately...
Computer Models for Dredged Material Disposal Planning
Short term and long term planning for the disposal of dredged material can be significantly enhanced using state-of-the-art computer modeling. Computerized mathematical models can be constructed...
Flow Parameters of Fluid Mud
A set of small-scale, high-resolution velocity and stress sensors based on rugged metal-clad hot wires and epoxy-encapsulated hot films is to be evaluated for its performance characteristics...
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....
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...
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...
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...
Cavitation in Various Types of Shear Flow
Cavitation in turbulent shear flow depends on the intensity and spectral characteristics of the pressure fluctuations in a Lagrangian frame of reference as well as depending on the concentration...
Modeling of a Multifunctional Hydraulic Structure
A 1:12 scale Froude model of a hydraulic control structure in the Rochester Combined Sewer Overflow Abatement Program (RCSOAP) was constructed and tested to optimize the design requirements...
Power from a Water Supply System: A Resource Which Can Be Tapped
There are numerous water supply systems from which hydroelectric power could be developed without impending the regular operational schedule. The basic principle of operation is not different...
Design and Operation of Pipeline Control Systems
More and more of the time of the engineer involved in the design and construction of a pipeline project is devoted to problems relating to the control systems to operate and monitor the...
The Third Wave in Water Quality Management
In the 1970's there was great pressure to clean up water-polluting discharges no matter what the cost. Now in the tight-budget 1980s, there is a vigorous search for more cost-effective...
Design of Bridges for Ice Forces
Sources of knowledge on ice forces and ice effects on bridges are listed and discussed briefly. Comments are made on experience of damage by ice and on the influence on bridge costs of...
Design of Navigational Structures for Ice Forces
An overview of ice conditions and the types of ice action that are hazardous to navigational structures is presented. Depending on the circumstances, ice failure against structures occurs...
