Water Use Pattern of Residential and Commercial Customers
The availability of the Automatic Meter Reading (AMR) devices make it possible to read a large number of meters in a short period of time. Through the use of AMR, we monitored weekly water...
Incorporating Weather Effects in Project Simulation
Planning of construction operations and projects must take into account weather conditions and the resulting impacts on the project schedule. Predetermination of weather and its resulting...
Reducing Ambiguity in Qualitative Reasoning
Qualitative reasoning derives the behavior of a physical system using a representation of the fundamental principles for the domain. In qualitative reasoning parameters are mapped into...
Foundation Uniform Pressure and Soil Structure Interaction
The enclosed paper was presented in the ASCE, 8th Conference on Computing in Civil Engineering and published in its proceedings. One of its main assumptions was considering the foundation...
Time-Dependent Analysis of Nonprismatic Curved PC Box Girder Bridges
The purpose of this paper is to present a step-by-step computer method for predicting the deflection and stress distribution duo to creep and shrinkage of concrete in nonprismatic, curved,...
Rive, Rive-Grown and Burst Probability of Rolled Compressive Concrete Arch Dam
The rive, every step of the rive grown and even burst of arch dam are regarded as sequence random events. Making use of the probability theory and the achievement of elastic, elastic-plastic...
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...
Intercity Travel Demand Forecasting for the Windsor-Quebec City Corridor
Travel demand forecasts were required for the 600-mile-long Quebec City - Windsor Canada Corridor to test alternative rail systems including high speed rail. The approach involved application...
Status of Contamination in the Coastal United States as Revealed from NS&T Analyses of Surface Sediments
Sediment samples have been collected from more than 300 sites along the coasts of the U.S. since 1984 as part of NOAA's National Status and Trends (NS&T) Program. These samples...
The NS&T Intensive Bioeffects Surveys: Design Strategies and Preliminary Results
Intensive bioeffects surveys are conducted in selected areas where chemical data from the National Status and Trends (NS&T) Program indicate greatest potential for contaminant-related...
The Specific Peculiarities of Relief Transformation and Shelly Sediment Differentiation in Coastal Zone
The settling velocities values of shelly sediment considerably differ from ones of the same particles of terrigeneous material and for this reason character and intensity of hydrodynamic...
Trace Metal Distribution in the Sediments of the Bight of Bonny, South Eastern Nigeria
Coastal sediments are important hosts for pollutant trace metals. The concentration and distributions of heavy metals depend on factors such as grain size of sediments, availability and...
Storm Precipitation in Southwest British Columbia
The storm precipitation in a mountainous watershed in the southwestern British Columbia has been studied. Analysis of the spatial distribution of the storm features showed that the precipitation...
Development of an Isohyetal Analysis for Oregon Using the Prism Model
PRISM (Precipitation-elevation Regressions on Independent Slopes Model) is an analytical model that uses point data and a digital elevation model (DEM) to generate gridded estimates of...
Friction Factors in Coastal Flooding
As the world's coastal zones are being developed and the coastal population increases, coastal flooding, or rather the prediction of its extent and frequency of occurrence, becomes a more...
Hydraulic Modeling of Alluvial Plains (Slopes) and Alluvial Fans Using DAMBRK
The design of hydraulic structures such as bridges on distributary flow areas and alluvial fans require methods that can adequately determine discharges at the structures. Flow conditions...
RCHARC: A New Method for Physical Habitat Analysis
The Riverine Community Habitat Assessment and Restoration Concept (RCHARC) is applied to the Gavin's Point tailwater of the mainstem Missouri River as part of studies by the U.S. Army...
Statistical Analysis of Extreme Hydrological Droughts
The study examined several works about extreme droughts for their validity with different parameters by the statistical experimental method. The results showed that the analytical method...
Robust Estimators in Hydrologic Frequency Analysis
This paper applies a specific robust estimation procedure known as 'trimming' in flood frequency analysis. The trimming technique consists in censoring the series of recorded floods by...
The Method of Derived Distributions Applied to Peak Flows
Random variables which are functionally related have their probability distributions also related in a prescribed manner. Thus, in theory, the probability distribution of peak discharge...
