Road to Recovery
The effect of the Loma Prieta earthquake on San Francisco's elevated viaduct system is still being felt more than four years later. Immediately after the quake, the entire...
Functional Analysis of the Envelope Design Process for Integrated Building Design
Building envelope failures account for a great portion of building failures. The number of envelope deficiencies would be reduced if the design process was integrated. Integration would...
Pile Settlement Based on Dynamic Measurements
Dynamic measurements during driving are well established for monitoring driving performance and the prediction of pile capacity. Post driving, signal matching office methods (e.g. CAPWAP)...
Analysis of the Juturnaiba Embankment Dam Built on an Organic Soft Clay
The Juturnaiba Dam, located in the northern part of Rio de Janeiro State, Brazil, has 1.2 km of its length built on an organic soft clay about four meters deep. The construction of the...
Down Drag on Friction Piles: A Case History
The down drag settlements experienced by the foundation of a supermarket constructed in 1972 in Gretna-New Orleans, Louisiana are presented. Two different lengths of piles (12.2 m and...
Methods for Risk and Reliability Analysis
Recently, there has been considerable emphasis on the state of decay in the nation's infrastructure because of its importance to society's needs and industrial growth. Water distribution...
Risk and Reliability of Water Resources Infrastructure and Engineering Approaches to Risk and Reliability Analysis
The paper summarizes the second session of the conference which discussed the risk and reliability of water resources infrastructure as well as engineering approaches to risk and reliability...
Plain flooding: near field and far field simulations
The paper deals with the problems met in the attempt of simulating the plain submersion produced by a levee breaking in the inertia dominated region (near field), scaling with the typical...
Finite Element Algorithms for Modelling Flood Propagation
The paper details the numerical solutions adopted in the TELEMAC-2D code that solves the shallow water equations. The numerical choices have been driven by the need for computational efficiency...
Object-Oriented Finite Volume Dam-Break Model
This paper is devoted to Object-Oriented analysis and design techniques to two computational modules in the field of dam-breaking. The C++ Object-Oriented...
New Methods for Modelling Dam-Break Wave
Recent developments in numerical analysis for hyperbolic equations have led to new methods which solve shallow water equations including complementary equations for hydraulic jumps. An...
Two-Dimensional Dam-Break Flow Simulation in a Sudden Enlargement
The paper presents the use of a two-dimensional depth averaged mathematical model for an unsteady dam-break flow simulation in a sudden enlargement. Continuity and two momentum equations...
Free surface flow modelling on a complex topography
The aim of this paper is to describe the different construction stages and the validation of a free surface flow model on a complex topography. This model is based on the two dimensional...
Ultimate Depth of Scour Around Bridge Piers
A design equation for estimating ultimate depth of local scour at bridge piers has been proposed which is based upon the envelope curves drawn to published field data covering a wide range...
Bridge Pier Scour Equations - An Assessment
A comparative assessment of various bridge pier scour equations has been reported on the basis of analyzing a set of published prototype data from Indian rivers and other countries covering...
Natural and Dam Break Flood Routing in Mountain Rivers
The accuracy of four one-dimensional flood routing methods is assessed for extreme floods in various mountain river settings. This preliminary assessment focusses on the prediction of...
1993 Mississippi Record Stages and Levee Failures
Record-setting stages, flooding duration, and multiple levee failures are distinguishing features of the Mississippi River 1993 flood. The peak stages reached at stations along the Illinois...
Toe Scour Protection Methods
Toe scour protection is an important element in bank protection projects because undermining by scour at the toe is one of the major causes of failure of bank protection. Existing toe...
Alternatives for Overtopping Protection of Dams
Prepared by the Task Committee on Overtopping Protection of the Hydraulics Division of ASCE. This report summarizes the results of an inventory and...
A Thousand Points of Data
Significant cracking was discovered in a multistory parking garage shortly after construction. Was it safe to open? Based on visual inspection, a bridge was down-rated, with potential...
