Low-Flow Frequency Analysis with Censored Data
Log-linear regression models are often fit to low-flow quantile estimates from gauged sites to obtain a relationship for estimating low-flow quantiles at ungauged sites. In some regions...

Analysis of Missouri River System Operations Alternatives
The Corps of Engineers is conducting a study of alternative water control plans for the exiting Missouri River Mainstem System. Data on the effects of the alternatives on the various project...

How Many Observation Wells Does it Take to Find a Groundwater Contamination Plume?
A Bayesian data worth framework is developed to balance the benefits and costs of data collection. In addition to Bayesian decision analysis, tools from Monte Carlo simulation, numerical...

Linguistic Analysis of Risk in Project Planning
Construction risk analysis models are mainly based on quantitative techniques which require numerical data. However, in many cases, the available information related to uncertainty factors...

TIGER and Census Bureau Data in a GIS: A Powerful Combination for Civil Engineers
TIGER is the acronym the Census Bureau crated to identify its computerized geographic support system: the Topologically Integrated Geographic Encoding and Referencing System. Although...

3-D Coordinates - A Universal Rectangular Coordinate System for a GIS and Other Spatial Databases
Rules of solid geometry and 3-dimensional (3-D) rectangular coordinate systems are well known and used in many applications. Points on or near the earth's surface have long been described...

An Information Engineering Approach for Environmental Impact Assessment and Monitoring Program
Environmental impact assessment studies cover a number of activities for: data collection, data analysis, numerical modeling, system monitoring, and regulation compliance. The diversified...

An Object-Oriented Scheduling Data Acquisition Model Using a Hybrid Expert System
Acquisition of scheduling data for construction project information management is a complicated task. Historically, there has been a fundamental disconnection between cost estimation and...

A Decision Support System for Nonpoint Source Pollution Management Using a Distributed Model-GIS-DBMS Linkage
Methods were developed for directly linking the distributed parameter model, AGNPS with a GIS and a relational database management system (RDBMS) to investigate a nonpoint source pollution...

Multimedia Technologies for Civil and Construction Engineering Professional Practice
Multimedia can be classified as any experience or application that uses two or more media to convey a message or achieve a given purpose. Some of the main types of possible applications...

Strengthening the Design/Construction Interface Using Electronic Imaging, Document Management and Work Flow Technologies
The paper describes a conceptual approach for the implementation of document imaging systems as a mechanism for strengthening the design/construction interface. The paper discusses some...

Capturing As-built Project Information for Facility Management
Complete, accurate, and timely provision of as-built information plays a critical role in the optimal upkeep of a facility. Facility operators/maintainers usually are delivered a constructed...

A program for the Analysis of Pile Load Tests
The load capacity of piles are routinely determined from full scale pile load tests under actual field conditions. Several empirical methods were proposed for the analysis of field load/settlement...

Bridge Rating Using Influence Surface for Curved Bridge Structures
A fairly sizeable number of curved steel bridges in Louisiana need to be rated and influence lines required to be stored. A methodology is developed and rating procedures are established....

A Speed Prediction Model for New Zealand Highways
This paper outlines a limiting speed model using probabilistic techniques to simulate the different types of vehicles and their performance along a two-lane rural highway. The road to...

Design and Implementation of a Database for Seismic Evaluation of Structures
The seismic evaluation of large structures, such as bridges, requires a comprehensive framework for managing the data. An evaluation typically involves the dynamic analysis of a number...

Transactional Support for Concurrent Finite Element Analysis & Design
The finite element (FE) analysis and design process deals with large amounts of complex engineering data. Although sophisticated techniques have been developed for computer-aided FE analysis,...

Deductive Databases in Engineering
Many engineering systems can be modeled in terms of objects and relationships among objects. As generalized relational databases, deductive databases provide a suitable tool for representing...

Overflow Elimination Benefits from GIS Based Technology
Elimination of wet weather overflows through the rehabilitation of infiltration and inflow defects requires careful analysis of the collection system. The integration of geographic information...

Machine Learning in Civil Engineering ? Important Issues and Challenges
