The Economic Value of Trout Fishery Management Programs
The contingent valuation method is used to estimate the economic value of a trout fishing day at the Cache la Poudre River in Colorado. In addition, changes in daily economic value and...
Managing Instream Flows for Salmonid Spawning Habitat
Detrimental sediment related effects on aquatic habitat for anadromous fisheries include (1) deposition of excessive amounts of fine sediments in spawning gravels, and (2) mobilization...
Stochastic Forecasts in Reservoir Planning and Operations
The factors involved in stochastic forecasts of water supply and demand are discussed in relationship to reservoir planning and operating decisions....
Characterization of Uncertainty in Reservoir Operations
The development of operating policies for complex reservoir systems typically requires a consideration of various system component interrelationships and several conflicting operating...
Using Forecasts to Improve Reservoir Operations
This review considers methodologies that have or can be employed to incorporate streamflow forecasts into reservoir policies and operating decisions. These include the use of streamflow...
Seasonal Water Quality Management Given Sparse Data
An approach for designing robust seasonal water quality management programs for river basins with sparse or short flow records is presented. This approach uses Markov chain modelling and...
Imprecise Probability and Water Resources Decisions
In water resources engineering weak information would correspond to circumstances when the record is extremely short relative to the mean rate of occurrence of important design events,...
Integrated Water Resource Planning?A Northwest Case Study
The City of Tacoma Water Division recently incorporated integrated resource planning into its comprehensive water system planning process. This method of planning considers demand-side...
Optimal State Feedback Estimation in Groundwater: Application to Leaky Aquifers
The problem of groundwater flow in leaky aquifer is looked at from a stochastic point of view. Optimal estimation of hydraulic heads are achieved using Kalman filtering. The Kalman filtering...
Alternatives Analysis Using Two-Dimensional Modeling for the Owensboro Bridge and Approaches
The Federal Highway Administration plans to design and construct a new bridge over the Ohio River near Owensboro Kentucky. A hydraulic model with two-dimensional capabilities was utilized....

Computer Analysis of Cable-Stayed & Suspension Bridges
The finite element structural analysis of long span bridges is an area of research that has been studied within the past thirty years since the development and emergence of the digital...
Modeling Beam Torsion in Prestressed Concrete Box Beam Bridges
This paper briefly summarizes the development of a specialized finite element model capable of predicting the elastic and inelastic behavior of beam-slab type prestressed concrete spread...
NOISE?A Comprehensive Software Library for Highway Noise Analysis
The Noise Software Library is a collection of highway noise analysis software tools that are arranged together under a powerful file management system which provides a transparent method...
Finite Element Analysis and Design of Bridges with Applicatrons of ICAD
This paper describes applications of client-server models, interprocess communications (IPC), and concepts of intelligent CAD (ICAD) to the interactive design and analysis of highway bridge...
Finite Element Representation of Approach Slabs
Approaches to bridges are designed to provide a smooth and safe transition from the highway pavement to the bridge deck and back to the highway pavement. Generally this transition area,...
Grillage Analogy for Multigirder Bridges
Grillage analogy is a method frequently used to simulate the structural response of highway bridges with reinforced concrete deck and steel girders. This approach saves substantial efforts...
3D Template of Human Figure for CG Animation in Design
It has become commonplace to use computer graphics (CG) animation in architectural and landscape design. Historically, CG animation has been employed primarily as one of many presentation...
Object Based Visualization of Physical Behavior
In engineering science, the physical behavior of solids, fluids, gases and multiphase systems is analyzed with computational models. Numerical methods form the basis of the computational...
An Object Oriented Approach to Computing with Structural Components
The structural analysis process can be modeled in two separate steps: definition of structural systems and analysis of a discrete numerical model; the transmission between these two models...
