Numerical Modelling and Laboratory Verification for the Turbulent Flow Field in the Branching Channel
Adopting the depth-averaged k-? turbulence model and using the finite volume method and SIMPLE procedure, the turbulent flow field in the branching channel is numerically solved and verified...
Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations (SIDD)
This publication, Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations (SIDD), (ASCE 15-93), is applicable to buried concrete precast pipe intended...
Sludge Under Pressure
Few wastewater engineers ever have to deal with high-pressure pumping. In San Diego, however, city engineers will soon oversee a 100,000 ft long psi main that will transport sewage sludge...
Estimating Network Model Parameters from Mail Survey Data
Network models are generally based on a four-step modeling process; trip generation, trip distribution, modal split, and trip assignment. Microcomputer implementations of these steps have...
Data Base for Seismis Rick Assessment in Mexico City
We describe a model to estimate expected ground motions and expected damage, based on intensity damage relations derived for 14 classes of buildings representative of Mexico City construction....
System Factors in LRFD Format: A Multidimensional Judgment Call
A Load & Resistant Factor Design Specification for wood buildings is being completed. The Specification contains several revisions from the traditional 'repetitive member' factor...
Investigation in 3-D of Stress Distribution in a Circular Tunnel and Vertical Emplacement Holes Due to Thermal and Overburden Loading in Tuff
Thermal stress and displacement analysis using two 3-D finite element models, one having a course mesh and one having a highly detailed mesh are presented. Results are compared to those...
Estimation of Water-Filled and Air-Filled Porosity in the Unsaturated Zone, Yucca Mountain, Nevada
The responses of density and dielectric logs are formulated in terms if the matrix properties, air-filled porosity and water-filled porosity. Porosity values obtained from logs from borehole...
Effects of Core Sealing Methods on the Preservation of Pore Water
Five general core sealing methods (using Protecore, Lexan, wax, Protecore with wax, and Protecore with Lexan) were studied over a two year period to determine their moisture retention...
Solute Transport Characteristics of Fractured Dolomite in Southern Nevada, USA
Recirculating tracer tests in fractured Cambrian dolomite beneath the Amargosa Desert revealed (1) and 83-percent increased in apparent dispersivity resulting from a two-percent increase...
A Derived Flood Frequency Distribution for Ungaged Catchments
Flood frequency distribution for ungaged catchments are described in the article. The various parameters that effect the flood frequency distribution are describes. Influence of the climate...
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...
