Behavior of Horizontally Curved Steel Highway Bridges
Horizontally curved highway bridges represent up to 25 percent of the market for new steel-bridge construction each year. However, unanswered questions remain concerning the fundamental...
Reliability Curves for Reservoir Performance
Seattle District, U.S. Army Corps of Engineers, has developed a family of reservoir guide curves that illustrate reliabilities when storage conditions gradually decline from 98% to as...
Treating Uncertainty in the Design of Horizontal Curves
A model based on expected total cost minimization approach is developed for determining optimal horizontal curvature for highway sections. Expected total cost is defined as the sum of...
Colorado Dome
Innovative engineering and precise design helped engineers overcome a building's unique shape and difficult site to deliver the $71.5 million Jefferson County Government Center...
Environments Parameters of Sediments and the Interface Sediment-Water in the Tacarigua Lagoon (Venezuela)
A study was made of the sedimentological characteristics of a lagoon bottom, and of the anions present at the sediment-water interface. For this analysis, the lagoon was divided into five...
Peak Frequency Curves for the Middle Rio Grande
To define peak flow frequency curves for ten sites in the highly controlled and regulated Middle Rio Grande, an approach which relates peak inflow and peak outflow from the reservoirs...
Runoff Prediction by Recession Curves
Based on the characteristics of the discharge hydrograph such as the rising limb and the recession curve, a simple water tank model is constructed. This water tank has cross-sectional...
Neutron Gauge Calibration Comparison of Methods
Several methods for obtaining soil samples for determining soil water content were used for field calibration of neutron gauges. This paper compares the results of calibration curves obtained...
Design of a Curved Baffle Energy Dissipation Structure
A curved baffle energy dissipation structure was designed and constructed based on the results of hydraulic and analytical models. Field tests of the prototype demonstrate close comparison...
Rainfall Depth-Duration-Frequency Analysis for Major Cities in Taiwan
The annual series of extreme rainfall amounts for various durations are compiled. The statistics such as mean, standard deviation, coefficient of variation, coefficient of skewness, and...
The Challenge of Operating Roped Shuttles on Curved Guideways
Guideway curvature creates design challenges unique to roped people mover systems. These challenges include: Positioning large numbers of rope support sheaves along the guideway to support...
Inflation Instability of Cylindrical Membranes

A Mathematical Tool Set for SORM Reliability Methods
FORM and SORM methods are used for approximating failure probabilities. Here an overview of the main mathematical results of SORM methods is given: Classification of asymptotic behavior,...
A Frequency Surface for Rainfall Intensity and Duration
A technique for developing rainfall intensity-duration-frequency surface is presented. With the aid of the Box-Cox power transformation raw data is transformed into a jointly near normally...
A GIS Based Geomorphic Approach for the Digital Computation of Time-Area Curves
Hydrologists routinely operate simulation models to approximate the runoff process. A popular strategy is the routing of a 'time-area' histogram. In addition, state-of-the-art hydrologic...
Evaluation of Intensity-Duration-Frequency Curves by Point Precipitation Models
In this work an alternative approach to estimate the Intensity-Duration-Frequency curves is used. This approach which uses point precipitation models recently proposed in the literature...
A Bivariate Stochastic Reservoir Model
A bivariate distribution of peak flows and volumes is derived taking into account their correlation structure. This distribution is then used to derive reservoir operation curves which...
Analysis of Water Banking Projects as Additions to the California State Water Project
