A Knowledge-Based Computer System for Financial Wind Risk Management
This paper presents the results of a sponsored applied research project conducted by a multi-disciplinary team to integrate state-of-the-art methods in wind and collateral (e.g., surge,...
The Integrated Systems Approach to Facilities Management
This paper investigates the condition and use of the systems for facilities management and discusses process and considerations for improving the long term value of integrated facilities...
Mat Foundation Design: An Historical Perspective
Nearly a half century ago, Karl Terzaghi rationalized the analysis and design of mat foundations with the conclusion that subgrade reaction was the most important variable. Soon after...
Settlement of Large Mat on Deep Compressible Soil
This case history describes the settlement analyses for a large load compensated (floating) mat foundation on a deep deposit of normally consolidated clay of variable thickness. Large...
Influence of Flexible Mat on Settlements of Marine Clay
Highly compressible marine clays occur extensively in coastal regions. In lieu of traditional pile or raft foundations in such weak soils, recently a flexible mat system has been developed...
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...
Reliability-Based Assessment of Corps Structures
Due to the limited amount of funding available for maintenance, rehabilitation, and replacement of aging Corps structures, the director of civil works, Headquarters, U.S. Army Corps of...
Quantifying Flood Damage Uncertainty
The U.S. Army Corps of Engineers (Corps) has adopted a risk-based analysis procedure to analyze the effect of uncertainty on flood damages and the benefits of flood damage reduction projects....
Risk-Based Budgeting for Maintenance Dredging
The U.S. Army Corps of Engineers must estimate the budget required to conduct maintenance dredging at hundreds of sites across the country. The amount of funds needed to do the maintenance...
Developments in Risk Analysis Commercial Software
There has been a marked increase in the number and type of commercial software packages available to support risk and uncertainty analysis. Monte Carlo simulations, the first such tool,...
Automated ORP Control for Aerobic/Anoxic Cycling in Oxidation Ditch Treatment
The 1140 m3/d (0.3 mgd) Grand Coulee, WA. oxidation ditch was modified to incorporate a computer-control anoxic/aerobic cycle operation to investigate...
A comparison between computed and measured bed evolution in a river bend
A shallow-water scheme with a movable bed has been employed in order to check the reliability of computations related to the bed evolution when a substantially three-dimensional phenomenon...
Demonstration Project for Scour Instrumentation
A Federal Highway Administration (FHWA) Demonstration Project was developed to facilitate technology transfer of instrumentation related research to the highway industry. The objective...
A Computer-Controlled, Precision Pressure Standard
The operating principles as well as the technical aspects of the implementation of a precision pressure standard are presented here. The instrument can have dual use: either as a pressure...
Sensitivity Analysis of Bridge Equations
Computation of riverbed scour at the 482,000-plus bridges over water in the United States of America requires a significant level of hydraulic engineering effort. To do cost-effective,...
HEC River Analysis System (HEC-RAS)
The Hydrologic Engineering Center (HEC) is developing next generation software for one-dimensional river hydraulics. The HEC-RAS River Analysis System (HEC, 1994) is intended to be the...
Improved Hydraulic Features of the HEC River Analysis (HEC-RAS)
The Hydrologic Engineering Center (HEC) is in the process of developing a Next Generation (NexGen) of hydrologic engineering software. The goal in the area of river hydraulics is to develop...
An Approach to the Calculation Method of Mean Sediment Size
Mean sediment size is an important parameter expressing the characteristics of sediment. Several calculation methods of mean sediment size which are popular at present almost have some...
Salinity and Dissolved-Oxygen Dynamics in a Wind-Driven Estuary
Water levels, near-surface and near-bottom salinities, and near-surface and near-bottom dissolved-oxygen concentrations were measured continuously in the Pamlico River estuary, North Carolina,...
