Ice Forces on Bridge Piers
The force that river ice exerts on bridge piers has been studied in the field and with models in the laboratory. Ice forces are a function of the strength, thickness, failure mode and...

Quality in the CM Constructed Project
The services of the testing laboratory on construction projects have not generally been considered as part of the construction management function. If the intention of construction management...

Effectiveness of Extended Detention Ponds
Field and laboratory studies of the performance of detention facilities for the removal of selected pollutants from urban stormwater were conducted. The laboratory studies consisted of...

Research on Transportation Facilities in Cold Regions
Transportation facilities research in cold regions, reported in this session proceedings, begins with a field study showing that ground surface characteristics have a significant effect...

Concrete Rehabilitation Options and Solutions
This paper demonstrates the basic steps for a successful rehabilitation program using a case study of the rehabilitation work for the NASA/JPL 64-meter deep space communication antenna....

Analysis of Liquefaction Potential of Hydraulically Placed Subsea Berms
The use of hydraulically placed sand for the construction of artificial islands for hydrocarbon exploration in the Beaufort Sea has necessitated detailed geotechnical evaluations of their...

Negatively Buoyant Flow in a Diverging Channel
Negatively buoyant (plunging) flow from a horizontal, constant width channel into a diverging channel has been studied in the laboratory. The study was undertaken to provide information...

Making Treatment Plants Work
For the most part, past design criteria that have been used were based primarily on historical information from plants that worked or general rule of thumb criteria. With the increasing...

Behavior of Drilled Piers in Layered Soils on Texas Barrier Islands
Twenty-eight full scale load tests and the results of 41 geotechnical studies were analyzed to correlate shear strength interpreted from field and laboratory test data with those derived...

Grout Slurries?Thick or Thin?
In this paper some recent experiences in dam grouting in several countries are discussed where bentonite or Intraplast additives were used to control sedimentation, viscosity, grout density,...

Computer Simulation of Lime-Soda Softening of Cooling Waters
A computer model is developed to simulate the process of lime-soda softening of cooling waters. Results from the model are compared with those from a laboratory experimental study using...

Theoretical and Experimental Evaluation of Single-Activated Sludge
The objective of this paper is to discuss the results of operating a laboratory bench scale compartmentalized activated sludge unit operated at a hydraulic detention time ( theta ) of...

Coastal Zone Management in Emilia-Romagna, Italy
The beaches of the seaside resorts in the Emilia-Romagna region are of great importance to the regional economy. During the last decades, certain natural and man-induced developments have...

A Study of Inlet Control Alternatives for SWM
A laboratory study of alternatives for effecting inlet control on urban storm sewer systems for stormwater management (SWM) is described. The test facility was a full-size physical model...

Integration of Micro, Mini, and Mainframe Computers in WES Hydraulics Studies
The U. S. Army Corps of Engineers Waterways Experiment Station (WESA) Hydraulics Laboratory is involved in hydraulic studies of navigation and flood control projects of the Army Corps...

Frazil Ice Control Using Air Guns
The design of the J. H. Campbell, Unit 3, Cooling Water Intake in the late 1970's used some new ideas and concepts in response to a strong concern for fish protection at a...

Laboratory Studies for the J. H. Campbell, Unit No. 3, Cooling Water Intake Design
A three-year study sponsored by the Empire State Electric Energy Research Corporation was conducted to determine the overall efficiency of a full-scale angled screen demonstration facility...

Embankment Overtopping Tests to Evaluate Damage
The paper reports on studies of embankments 6 ft high, 10 to 22 ft in crest width, and 3 ft in length, with slope varying from 2:1 to 4:1. Embankment surfaces include pavement, grass,...

Electronic Worksheet Applications in Hydrology and Hydraulics
Spreadsheet software packages are available for virtually all micro computers in use today. Although they are quite often thought of as business tools, their usefulness as engineering...

Microprocessor-Based Data Acquisition Systems
The application of microprocessor-based data acquisition systems to laboratory experiments and field tests is discussed. The importance of the system design and hardware selection is emphasized....
