Snake Reservoir Drawdown ? A Brief Progress Report
The Northwest Power Planning Council has directed the region to employ the use of 'Drawdown' as tool to help threatened and endangered salmon stocks in Snake and Columbia rivers unless...
Role of Economics in Endangered Species Act Activities Related to Snake River Salmon
The development of recovery actions for the species of Snake River Salmon listed under the Endangered Species Act (ESA) must consider a wide range of actions covering the different life-cycles...
An Historical Perspective on Water Resources Education
A professional education in water resources combines courses that apply sound science to meet popular needs with general knowledge on how society uses and views water. The graduate has...
Politics and Drought Planning: Friends or Foes?
Nothing frustrates the average drought planner more than politics. Yet, droughts cannot be prepared for realistically without reliable political partners, smoothly cooperating government...
Geothermal and Hydropower Production in Iceland
This paper will first consider the technical aspects of both hydropower and geothermal power production in Iceland. Then the economic consequences of the alternative utilization of these...
Price Elasticity and Conservation Potential
Water conservation programs usually contain pricing incentives for users to limit water consumption. This analysis uses data from the Portland, Oregon water system as an example of both...
The Evolution of Conservation Rates in Phoenix, Arizona
Conservation or increasing block rates first implemented in Phoenix, Arizona in 1982 were reexamined by a three year study involving Water Department staff, a Citizen Rates Committee and...

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...
Explanation Facilities for Intelligent Engineering Tutors
Intelligent Tutoring Systems (ITS) provide a method for humans to interact with a computer to learn about a particular topic. Usually, the ITS system has as part of its components a knowledge-based...
A Program Architecture for Interactive Nonlinear Dynamic Analysis of Structures
This paper discusses a general object-oriented architecture for use in nonlinear dynamic structural finite element analyses. In light of the special issues surrounding such analyses, the...
Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...
Construction Enterprise Management Computer-Aided Diagnosis Technique
Due to the problem existed in the traditional management consulting of construction enterprise, the author has developed the MCAD (Management Computer-aided Diagnosis) technology which...
Qualitative Formulation of Load Paths Through a Functional Description of Structures
The past few decades have seen major advances in computer tools to analyze complex structures and loadings. For the most part, these programs have focused on two areas - A, programs for...
Stress Analysis in Concrete with Cooling Pipes
A substructure method of finite element analysis is adopted in this paper to simulate heat transfer and thermal stresses in a concrete dam. The massive concrete structure is cooled by...
PDS: An Expert System for Distress Diagnosis of Flexible Pavements in Taiwan
Pavement distress diagnosis requires a significant amount of engineering judgement which is difficult, if not impossible, to be quantified. This is an excellent domain for the development...
Exchanging Layout and Schedule Data in a Real-Time Distributed Environment
Unpredictable site conditions and unforeseen changes in construction work may result in inefficiencies due to a shortage of work space and difficult access to critical areas on site. This...
An Application of Neural Networks to Hysteretic Modeling of Steel Structures
This paper describes an application of the neural networks to realistic hysteretic modeling. The neural networks learn from sample data (training cases) and make predictions for new cases....
Non-linear Analysis of a Cable Stayed Bridge
A concrete single-pylon cable-stayed bridge has been analyzed to investigate the ultimate capacity. Two different methods were used to investigate the nonlinear behaviour. First, a simplified...
On the Usage of AutoCAD as a User-Interface for a Finite-Element-Program
This paper describes the approach used by the author to take AutoCAD as a user-interface for an existing Finite-Element-package. Some principles concerning database management are discussed,...
