McCormick Bridge Scour Evaluation?A Case Study of a Tidal Bridge
Although the Federal Highway Authority has implemented procedures for bridge scour analysis in their HEC-18 publication, they do not indicate a procedure for scour depth determination...

Halloween Wave Transformation Near Virginia Coast
The Halloween Northeaster of October 29-31, 1991 generated a unique severe sea. The storm waves propagated through two wave stations which are 87 km apart. The wave spectra of the storm...

Repeatability and Oblique Flow Response Characteristics of Current Meters
Laboratory investigation into the precision and accuracy of various mechanical-current meters are presented. Horizontal-axis and vertical-axis meters that are used for the measurement...

A Comparison Between Two Kinematic Wave Solutions for Movement of Debris Flows
We compare an asymptotic kinematic wave solution for movement of debris flows with a solution obtained by the method of characteristics. The differences between the two solutions in the...

Roll Waves in Mud Flow
Permanent roll waves on a shallow layer of fluid mud which is modeled as a power-law fluid is studied. Based on long-wave approximation, momentum integral method is applied to derive the...

Turbulent Velocity Flutuations in Natural Rivers
The longitudinal and transverse components of flow velocity, as well as the normal and tangential stresses, must be expected to fluctuate with time and space when flow at a high Reynolds...

Prediction of Occurrence and Runoff Analysis of Debris Flow
A debris flow will occur on a slope when the rainfall exceeds a certain value determined by the hydraulic, geological and topographic properties of the slope. To estimate this critical...

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...

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...

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...

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...

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...

Evaluation and Monitoring of Pile Performance Using Dynamic Measurements in Supporting Offshore Structures
The installation of offshore platforms into deeper waters and new environments is accompanied by an increasing uncertainty in the structure response, foundation design and performance....

Advances in Site Characterization
Data Acquisition, Data Management, and Data Interpretation
This proceedings, Advances in Site Characterization: Data Acquisition, Data Management, and Data Interpretation, consists of papers presented...

Stability of Rock Armour Under Random Wave Attack: Performance of Non-Standard Rock Shapes and Gradings
Quarried rock is frequently used to protect coastal and shoreline structures against wave attack. Armour rock specifications generally exclude rock that is rounded or tabular, and gradings...
