Computer Modeling of Reservoir Sedimentation and Sluicing
A recently developed computer program which simulates the evolution, growth, and movement of a submerged delta in reservoirs was tested for Spencer Dam and Reservoir in Nebraska. The code,...
Decision Rules for Reservoir Releases
One of the problems faced with computer modeling of a multi-reservoir, hydro-power system is making decisions on how releases will be made. Reservoirs many times have multiple demands...
Development of a New Hydraulic Design Tool for Spiral Casing/Distributor Geometry
A novel computational model has been developed to predict highly complex turbulent flow in a combined spiral casing/distributor geometry. Validation of the computational model against...
Optimal Real-Time Control of Hydroelectric Power Plant Using Dynamic Programming
In this paper, an approach of optimal real-time control of hydroelectric power plant operations is presented. The methodology is based on a dynamic programming technique where the original...
Hand Held Powerhouse Control Console or Portable Data Terminal
The Portable Data Terminal (PDT) is a very small light weight hand held computer terminal that communicates with the control system computer by radio. An operator monitors power plant...
A Hydroelectric Plant Operator's Assistant
This paper describes a PC based application designed to assist in the process of enhancing the performance of multi-unit hydroprojects. Optimization considerations, uses of the Operator's...
Ferroresonance & the Snettisham Hydroelectric Project
Key system features of the Snettisham power plant in Alaska will be highlighted along with a discussion of the operational problems encountered due to a ferroresonant condition. The project...
Voltage Regulator Influence on Generator System Stability
During initial startup of a generator system, it is not uncommon to witness generator voltage instability. Most of the time, the solution is reduced to returning the stability control...
Validation Studies on Indexed Sequential Modeling for the Colorado River Basin
A method called indexed sequential modeling (ISM) has been developed by the Western Area Power Administration to estimate reliable levels of project dependable power capacity (PDC) and...
Operation of Hydropower Plants Considering Daily Streamflows
Operation of hydropower plants is a sequential decision process often modeled as a dynamic programming problem. Typically, such formulations consider monthly stages assuming that monthly...
Consideration of Sedimentation on Hydropower Projects
Experience gained by analysis of a number of hydropower projects throughout the world leads to the conclusion that it is necessary to consider sediment related aspects in the design and...
Hydraulic Design and Development of Propeller Replacement Runner for R. H. Saunders
This paper outlines the hydraulic design for the R.H. Saunders replacement runner. The six-bladed propeller runner was numerically optimized based on 3-dimensional flow simulation. After...
Development of an Eicher Screen at the Elwha Dam Hydroelectric Project
The Eicher Screen is a relatively new concept for screening juvenile fish out of hydroelectric turbine penstocks. The concept was developed by Mr. George Eicher and one was recently installed...
Decision Support for Colorado River Operations
The United States Bureau of Reclamation (Reclamation) uses a simulation model known as the 24-month Study Model for planning monthly and seasonal operations for the Colorado River Basin....
Pressure-Time Method Using Modern Practices
Over the past twenty years, Hydro-Quebec has modernized the pressure-time method of flow measurement, a method which is generally economical but sometimes difficult to apply. Starting...
A Decision Support System for Prediction of Crop Yield, Evapotranspiration, and Irrigation Management
Computer simulation models have been developed which predict growth, development, and yield for grain legumes. These models can be applied for yield prediction as well as water management...
Informed Use and Potential Pitfalls of Canal Models
