Experience with the Application of Fully 3D Potential Flow Analysis to Runner Design
Hydraulic turbines come in various shapes and types depending on their operating conditions. Their performance characteristics depend largely on the runner which is the most difficult...
Guidelines for Failure Investigation
The
Cautious Risk Taking
Traditionally, the design engineer could bear virtually unlimited liability for design failure. Now he is less vulnerable. The concept is less than 20 years old, but since the early 70s,...
Grouting Trends
The grouting industry is discussed and North American practice compared to European practice. There has been more innovation in this field overseas, but there have also been failures....
Specification as a Requirement for Hot Mix Asphalt
A brief description of the current national research programs that affect the development of specifications is included in this paper. Elements of the Strategic Highway Research Program...
Real-Time Project Tracking
Too often project tracking is based on a job costing program which charges costs to the project based upon invoices from vendors and payrolls of employees. The information obtained from...
Potential Misuse of Construction Scheduling Software
The advent of microcomputers, coupled together with the development of many easy to use and economical scheduling packages, has placed a very powerful tool in the hands of construction...
Effect of Planning Errors on Construction Safety
A discussion of the planning phase of the building process associated with all the activities that are accomplished during this phase is presented. The different types of errors that occur...
Eliminating Bias in Construction Schedules to Measure Time
Schedules developed for use in managing the construction process which are accurate for that use are not necessarily sufficiently accurate to measure and evaluate delays and changes to...
Project Control Via Acoustical Sensing
This paper describes ongoing research into automating the process of collecting project control information using acoustical sensing devices. The paper describes how frequency spectra...
Decision Support System for Achieving and Measuring Design Effectiveness
A microcomputer program is developed to serve as a decision system for improving design effectiveness. The program, called 'Design Effectiveness Evaluation and Implementation...
Pumped-Storage: An Analysis of Optimal Capacity
This paper presents a systems analysis procedure to evaluate planning alternatives for pumped-storage operated in an existing power system. This procedure can be used by planners and engineers...
Federal Vs. Non-Federal Hydroelectric Development
This paper presents the methodology and results of economic and financial analyses that were performed to indicate the optimum size powerplants that would be constructed assuming Federal...
Actual Vs. Expected Performance of Small Hydro Projects
This paper presents the results of several case studies of small hydro projects that compare the expected performance with the actual performance as measured in terms of energy generation....
The Uses of CADD in Hydropower Development
The hydropower community needs inexpensive methods to thoroughly and quickly analyze the siting of hydroelectric projects. Computer-aided design and drafting (CADD) and programs like HYSIZE...
Small Hydro Analysis and Reporting Program
The Ontario Ministry of Energy initiated a project to develop an analysis program based upon metric measures and Canadian costs. The Ministry of Energy of the Province of Ontario has been...
Cumulative Impact Assessment: Application of a Methodology
The authors expanded upon the Federal Energy Regulatory Commission's (FERC) Cluster Impact Assessment Procedure (CIAP) to provide a practical methodology for assessing potential...
Glen Canyon Environmental Studies Resource Response Analysis
The primary objective of the Glen Canyon Environmental Studies is to determine how the resources of the Grand Canyon respond to the operations of Glen Canyon Dam. Two levels of analysis...
Systems Analysis for Fisheries Protection and Mitigation at Corps of Engineers Columbia River Dams
Pacific Northwest anadromous salmon and steelhead that migrate to and from the ocean are greatly affected by the numerous Columbia and Snake River dams they have to pass, first downstream...
Hydropower Simulation: An Overview
