Stopping Seepage
The Navajo Dam in New Mexico has major seepage problems. The Bureau of Reclamation, which owns the Dam, conducted studies, verified by outside consultants, concluding that the combination...
St. George Harbor?A Berm Breakwater Solution in Alaska's Bering Sea
The berm breakwater concept is based on the premise that locally available materials should be used in breakwater construction to the largest degree possible. By looking at failure dynamics...
Natural Stabilization of an Eroded Permafrost Site
The paper referred to in this abstract discusses the erosional processes during and after the initial failure, proposed solutions to repair and stabilize the site, and details of the performance...
Building Around a Building
Many, maybe most, construction disasters occur as the result of the failure of temporary structures. Despite the fact that temporary structures have a critical effect on the speed, safety...
California's Fourteen Years of Coastal Zone Management
California's Coastal Zone Management Program has been considered the flagship of the nation; yet large questions remain as to whether the program can protect California's...
Hazardous Waste Landfill Cap System Stability
Pursuant to the regulatory requirements for control of rainfall infiltration into a hazardous waste landfill, a cap design that is impervious plus stable is required. The intent of a cap...
Temporary Structures in Construction Operations
Temporary works have a primary influence on the quality, safety, speed and profitability of all construction projects. They provide access, support and protection of a facility under construction....
The Mexico Earthquakes?1985
Factors Involved and Lessons Learned
This publication reports initial results of study of the 1985 Mexico earthquake, one year after the event. The findings present sufficient depth of analysis to provide an understanding...
Sound Structure
A new concert hall in Dallas, Tex., has the first acoustical design done with the aid of computer simulations that also dictated the shape of the performance space. Those dictates, in...
Investigating Failure
Failure investigations can be adversarial or cooperative, but impartiality, good engineering ethics, and professional responsibility require that the investigator begin with no premature...
Predicting Equipment Failure
At Cleveland's Westerly Water Pollution Control Center, the physical/chemical plant for treating wastewater is one of the largest of its kind, with 50 mgd average capacity....
Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...
Verification of a Generalized Mudflow Model
This paper presents the results from recently completed studies verifying the accuracy and applicability of a generalized one-dimensional model for dynamic routing of mudflows. Numerical...
Management of Water Distribution System Components
The purpose of this study is to 1) analyze main break failures and 2) incorporate other drinking water distribution system components into a data base management structure for reliability...
Embankment-Dam Breach Parameters
The study used data from 43 embankment-dam failures to develop equations that predict breach formation model parameters. These data include the failure mode, embankment characteristics,...
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...
Statistical Analysis of Embankment Dam Failures
Data on embankment dam failures in the State of Colorado were analyzed. The analyses included 1,900 dams and covered a time period from 1799 to 1985. The three basic categories of data...
Analytical Simulation of Bulk Water Supply Network Reliability
The authors present an analytical method for estimating failure probabilities for a bulk water supply network with spatially dispersed supply, demand, and storage. The method examines...
Discharge and Depth Behind a Partially Breached Dam
The role that the velocity-distribution correction factor plays in the determination of the flood discharge and corresponding flow depth behind a partially breached dam is investigated....
Limitations of Saint Venant Equations to Model Flood Waves
The subject of this paper is in direct contrast to all previously known research efforts. Previous effort has focused on simplified forms of Saint Venant using approximate routing models...
