Seismic Analysis of Safety-Related Nuclear Structures and Commentary on Standard for Seismic Analysis of Safety Related Nuclear Structures
This standard provides requirements for performing analyses to obtain design information which will lead to the reliability of structures under a severe earthquake. The goal of this standard...

Engineering Aspects of Soil Erosion, Dispersive Clays and Loess
This collection of papers deals with selected engineering aspects of soil erosion, dispersive clays and loess. Two types of erosion are considered?surface and subsurface (piping)?with...

Dynamic Response of Pile Foundations?Experiment, Analysis and Observation
In recent years, a considerable amount of attention has been paid to the dynamic response behavior of pile foundations. However, mainly because of difficulties in conducting tests and/or...

Detection, Control, and Renovation of Contaminated Ground Water
The papers in this book provide technical guidance to engineers regarding the problems, solutions, and uncertainties associated with groundwater contamination in the United States. The...

A Safer Earthquake Design Approach
The Uniform Building Code earthquake code permits taking advantage of a frame's capacity to absorb energy at stresses beyond yield. Dropping that provision would save lives....

The National Incinerator Testing & Evaluation Program
Environment Canada, under the National Incinerator Testing & Evaluation Program (NITEP), is addressing emissions from municipal energy-from-waste combustion systems. The main thrust...

Experiments on Culvert Flow
Laboratory experiments are described which were performed on small-scale models of smooth circular culverts of length-to-diameter ratio varying between 13 and 52, and longitudinal downward...

Hydraulic Structures on Piles
Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses...

A Comparison of Tidal Sediment Boundary Layer Profiles with Theory
A number of theoretical derivations have been presented for predictions of the sediment concentration profile near or at the bottom of a column of surface water. Ultrasonic transceivers...

Time Variability of Suspended Material Concentrations in Estuaries
The concentration of suspended materials (SMC) within estuarine systems varies in response to a variety of factors. This variability complicates sampling SMC and establishes particular...

Laboratory Study of Mud Flows
In the study reported depth profiles and tip velocities were measured for a series of unsteady mud flows generated in a laboratory flume using a dam break scenario. Observation of a wide...

Rehabilitation Measures?Wanaque Reservoir System
The rehabilitation of Pompton Lake Dam and the dams of the Wanaque Reservoir System has provided the North Jersey District Water Supply Commission with a safe, dependable source of water...

Consolidation of Slurried Soils
This paper describes the use of large strain consolidation theory and centrifugal modelling to study the consolidation behavior of slurries. Laboratory testing of the slurry is needed...

An Investigation of the Alcatraz Disposal Site
The Alcatraz dredged material disposal site in San Francisco Bay is a dispersive site that is not intended to accumulate disposed sediment. However, the recent discovery of shoaling at...

GLVHT Model Verification using Field Data
The Generalized, Longitudinal-Vertical Hydrodynamic and Transport model (GLVHT) as developed for the U. S. Army Corps of Engineers Waterways Experiment Station and described in Buchak...

Scour Downstream of High Level Emergency Spillways
The Corps of Engineers has numerous high level emergency spillways (HLES) including some that have the potential for excessive scour downstream during certain flow events. 'Excessive...

Development of Scour Channel After Spillway Failure
In November 1985 parts of the spillway which controlled the water level in Lake Charleston failed during a moderate flood event. The spillway failure resulted in formation of a large 'sinkhole'...

Modeling Materials for Protecting Earth Weirs
This paper reports laboratory experiments on various materials used to protect earth weirs. Dumped rock, gabion mattresses, and shaped blocks on a gravel layer were subjected to high velocity...

Evaluation of Sand as a Modeling Material Using Vellinga's Guidance
An experimental series of flume tests were conducted using three sizes of sand as modeling sediment in order to evaluate the effect of sediment grain size and the range of validity of...

Improved Robustness of the NWS DAMBRK Algorithm
The combination dam breach and flood routing numerical model called DAMBRK has been developed by the National Weather Service (NWS) for forecasting river flooding events (Fread, 1984)....
