Quantity and Quality of Dry Weather Flow in Las Vegas Valley, Nevada
In recognition of the potential for dry weather flows to convey pollutants from the Las Vegas Valley, the potential economic and resource value of these flows within the Valley, and the...

The Concept of Local Euler Number as an Aid for Sizing Pitot Tubes
Correlations with drag coefficients enable determining the relations between the form of Pitot tubes and their velocity coefficients. A numerical example is presented to clear the use...

Estimating Bridge Scour in New York from Historical U.S. Geological Survey Streamflow Measurements
Historical streamflow measurements by the U.S. Geological Survey an bridge-inspection reports by the New York State Department of Transportation are being used to estimate scour at 31...

Relation of Local Scour to Hydraulic Properties at Selected Bridges in New York
Hydraulic properties, bridge geometry, and basin characteristics at 31 bridges in New York are being investigated to identify factors that affect local scour. Streambed elevations measured...

Large-Scale Embankment Overtopping Protection Tests
The U.S. Bureau of Reclamation (Reclamation), Colorado State University (CSU), and the Electric Power Research Institute (EPRI) have an ongoing cooperative research effort to determine...

Progressive Failure of an Overtopped Embankment
The failure of an overtopped embankment is a problem of a very complicated nature. Concerned organizations are interested in information that can be used in future planning and development...

Oxygenation Experiments in the Wave Breaking Zone
Experiments on oxygenation due to waves breaking on a uniformly sloping beach were carried out at the laboratory of Harbor Works, National Technical University of Athens. The influence...

Reference Surfaces for Bridge Scour Depths
Depth of scour is measured as the vertical distance between scoured channel geometry and a measurement reference surface. A scour depth measurement can have a wide range depending on the...

A Finite-Difference Model for 3-D Flow in Bays and Estuaries
This paper describes a semi-implicit finite-difference model for the numerical solution of three-dimensional flow in bays and estuaries. The model treats the gravity wave and vertical...

The Courant Number and Unsteady Flow Computation
The Courant number C, the key to unsteady flow computation, is a ratio of physical wave velocity, ?, to computational signal-transmission velocity, ?, i.e., C = ?/?. In this way, it uniquely...

A Culvert Analysis Program for Indirect Measurement of Discharge
A program based on the U.S. Geological Survey (USGS) methods for indirectly computing peak discharges through culverts allows users to employ input data formats used by the water surface...

Three-Dimensional Modeling of Tides and Wind-Waves
A third-generation coupled discrete numerical wave prediction model is dynamically linked to a three-dimensional hydrodynamic model. The effects of water level, currents, and bottom friction...

Flow Study of In-Service Sanitary Sewers Rehabilitated with Insitupipe
In an effort to define the flow characteristics of sanitary sewer segments rehabilitated with Insituform under normal in-service conditions, Insituform of North America, Inc. (currently...

RCC: Rehab Results
Thirty dams have been modified with roller compacted concrete in order to provide additional spillway capacity and for safe overtopping of embankment dams. In the national dam safety inspection...

Nondestructive Testing Role in Repair and Rehabilitation of Concrete Structures
Nondestructive testing (NDT) methods are increasingly being used to assess the condition of structural concrete. The paper discusses applications of NDT methods for forensic investigation...

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...

Piles for Marquette University Math Building
This paper presents a comparison of static pile capacity predictions using CPT cone resistance results with results of a test pile program and production pile driving. Pile capacity prediction...
