Rate of Under-Registration Due to Failures of Large Meters
Leaks and meter under registrations are suspected as primary components of unaccounted-for water in Korea. In 2001, national unaccounted-for-water rate is reported as 26.6%. More than...

Bayesian Approach to Support Design of a Groundwater Long Term Monitoring Plan
This paper discusses a retrospective data assimilation approach that allows one to examine the spatial and temporal differences between forecast and observed states. Their stability, or...

The Accuracy of Extrapolated Design Estimates with Hydrologic and Environmental Models
Extrapolation error in water resources and environmental modeling has not been the subject of adequate study in the past. In research and design, estimates obtained from regression models...

Effectiveness of a BioInfiltration BMP
This paper presents results from a project to construct and study a BioInfiltration Traffic Island on the grounds of Villanova University. The projects goals were to 1. To create a bioretention...

Failures and Problems with Lift-Slab Construction
This chapter provides an overview of failures and problems with lift-slab construction. Topics include jack systems with inadequate take-up devices; the Canadian wedge connection; Serra...

Recent Advances in Optimal Structural Design
Sponsored by the Technical Committee on Structural Design of the Technical Administrative Committee on Analysis and Computation of the Technical Activities Division of the Structural Engineering...

Deep Freeze
In engineering, overcoming a failure can sometimes be more instructive than completing a project with unqualified success. Such was the case with the collapse and repair of a force main...

Advances in Buoy Technology for Wind/Wave Data Collection and Analysis
Considerable advances have been made recently to reduce the cost of gathering meteorological and oceanographic data from coastal waters, especially for meteorological and oceanographic...

Applications of Multibeam Echo Sounding with Topographic Mapping for Monitoring of Rubble Mound Breakwaters
Analysis of data from the breakwater monitoring program indicates the integration of multibeam survey capability with the increased accuracy of OTF DGPS positioning and advanced data management...

Raising the Bar - 345kV Uprating
The paper presents solutions to increasing the transfer capacity (book rating) of two critical 345kV tie lines. Described are computer modeling techniques using laser survey data coupled...

Geotechnical Aspects of Beach Restoration
Large-scale beach restoration undertaken by the U.S. Army Corps of Engineers in Florida requires millions of cubic yards of beach quality sand. Exploration for these sand resources starts...

Saving Saluda
One of the largest roller-compacted-concrete berms in the United States will stand sentinel in case South Carolina's Saluda Dam undergoes liquifaction in response to strong...

The Determination of Velocity Spectra and Dissipation by Direct and Indirect Means using Second-Order Accurate PIV
In this paper we present a 2 nd order accurate technique in space (following Wereley & Meinhart's (2001) extension of Cowen & Monismith's (1997) dynamic sub-window PIV...
