Pipeline Leak Detection Based on Mass Balance
Current technologies in Supervisory Control and Data Acquisition (SCADA) systems enable pipeline leak detection to be carried out in real time by software-based methods. This paper discusses...
Relocating a 54-Inch Diameter Force Main without Interrupting Wastewater Flow
The City of Tampa, Florida, was faced with the challenge of relocating three segments of an old 1372 mm (54-in.) diameter reinforced concrete pipe force main, totaling nearly a mile in...
Morphological Methods for Characterizing Inter-feature Distances
Characterizing inter-feature distances in digital images using automatic image analysis systems presents problems not found when quantifying the morphology of the features themselves....
Digital Image Techniques for Volume Change Measurements in Triaxial Tests
This paper presents an innovative technique that has been used for measuring the volumetric deformation that cylindrical specimens experience during the shearing stages of a triaxial test....

Use of Pressuremeter in Mixed Highrise Foundation Design
The pressuremeter has been used extensively for the evaluation of strength and deformation characteristics of the glacial hardpan soils in the design and construction of caisson foundations...
Driven Then Pushed Minicone Tests in a Sand Chamber
For a general knowledge on the Standard Cone Penetrometer test and its uses the reader is referred to the work of Briaud and Miran (1991). For this study (Khalaf and Briaud, 1992) a smaller...
Permeability Determination for Unsaturated Soils
A reliable approach for the determination of the soil hydraulic conductivity function relies on the parameter estimation solution approach in which heterogeneous state of saturation within...
Transit Times Through Compacted Clay Liners
Transit time, or time taken by waste liquid to move through the thickness of the liner, is a short-term performance parameter which can be used to determine the necessary liner thickness....

Comparison of Model and Field Results for Barbers Point Harbor
As waves travel into harbors from deep water, nonlinear processes lead to transfers of energy from the wind wave frequencies to long waves with periods of the order of several minutes....
A Design Manual for Coastal Fluidization Systems
This paper summarizes a recently completed design manual on fluidization systems to manage sand in the coastal environment for sand bypassing at inlets and harbor mouths and for creating...
Remote Automated Wave and Water Level Monitoring System Deployed at Agat Harbor, Guam
Agat Harbor, Guam is a small boat harbor excavated from a coral reef flat and protected by a detached breakwater. An automated monitoring system was designed and installed to observe wave...
Should the U.S. Accept the Concept of Navigable Depth?
Navigable depth is defined as the maximum depth of water from the chart datum that is safe to accept as the bed of the channel, such that damage does not occur to a ship's hull and maneuverability...
Sonic NDE of Structural Concrete
Case histories are presented to illustrate applications of nondestructive evaluation (NDE) methods that use stress waves to characterize the conditions of concrete construction. The case...
Wave Interaction with Fluid Mud in Rectangular Trench
Wave interaction with fluid mud in a rectangular trench is studied theoretically based on small-amplitude wave theory. The problem was formulated using the Voigt model for an viscoelastic...
Aspects of Parallel Processing in Reservoir Simulation
Vectorization techniques have proved to be extremely effective for large-scale reservoir simulations. Parallel capabilities hold even greater potential for these enormous problems. Domain...
Wavelet Transform Analysis of Several Transient or Nonstationary Phenomena in Engineering Mechanics
Several examples of the use of a wavelet transform in the analysis of transient events in mechanical systems are provided. The transform has the advantage over other transient analysis...
Nonlinear Behavior of Thin Slender Free Surface Non-Newtonian Elliptical Rings
This paper analyzes the nonlinear motion of a slender concentric thin elliptical ring of an incompressible, non-Newtonian fluid. This study includes the physical effects of surface tension,...
