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...

Instream Flow Methodologies and Requirements
Instream flow is a term applied to the discharge occurring downstream from and at least partly controlled by a dam or diversion structure. The volume and timing of instream flows most...

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
Numerous models have been developed for production costing and generation system expansion which include operation of hydropower in the system. These models rely on energy production and...

A Short-Term Hydro Scheduler for Hydro-Thermal Power Systems
This paper presents HYDSIM (Hydro-electric Simulation), a new versatile computer model developed to simulate the hourly or daily operation of a large network of multi-purpose reservoirs...

Real Time Hydropower Scheduling for Niagara Mohawk Power Corporation
Niagara Mohawk Power Corporation (NMPC) presently manually schedules their hydro system of 660 MW (80 stations in ten river basins). The scheduling procedures are labor intensive and relatively...

Reservoir Regulation in the Monsoon Climate of Korea
An examination of reservoir regulation rules in light of uncertain estimates of river flow in the Han River Basin, Republic of Korea, shows that two strategies will improve total hydroelectric...

Hydrologic Dispatch Model for a Hydropower System
A hydrologic dispatch model was developed for an 11 plant, six reservoir hydroelectric system. The model incorporates load forecasting, system dispatching strategy, and database management...

The Use of Time Series Analysis to Estimate Flow Duration Curves to Assess Energy Potential for Low Head Hydro Redevelopment
The proposed hydroelectric site location has a low head potential making discharge the primary energy production component. A flow duration curve (FDC) study was commenced to generate...

New Martinsville Hydroelectric Project
The 34MW New Martinsville Hydroelectric Project is presently under construction in West Virginia. Located at Hannibal Locks and Dam near river mile 126 downstream from Pittsburgh, PA,...

A Mathematical Model for Traveling Screens at Hydropower Plants
Hydroelectric projects cause significant mortality to fish migrating downstream. The current method to reduce fish mortality at hydropower plants is the use of traveling screens. In this...

The Impact of Inlet Flow Characteristics on Low Head Hydro Projects
This paper discusses the intake civil designs, addressing head loss and flow distribution into the turbine intake. The impact of poor flow quality on head losses, turbine performance,...

Application of Split Roller Bearings in Small Vertical Hydro Turbines
The elimination of lower turbine bearing problems with regard to reliability and water flow contamination was the main concern of this project. A design was needed that would fit the existing...

Prototype Experience With Acoustic Flowmeters
The acoustic (ultrasonic) flowmeter offers many advantages over other methods for measuring discharge in penstocks for turbine performance tests. It is nonintrusive, inexpensive and may...

Tracer Dilution Flow Measurement Application to Short Penstock Length
Absolute performance evaluation of hydro-turbines requires the determination of flowrates. Flow measurement is probably the most difficult aspect of determining a unit's efficiency....

Turbine Efficiency Monitoring Utilizing Ultrasonic Flowrate Measurement
On-line turbine efficiency measurement can be achieved by ultrasonic flowrate measurement and state-of-the-art data acquisition techniques. A field performance test program conducted at...

Upper Yellow River Projects and Longyangxia Station
The river stretch from Longyangxia to Qingtongxia, with a head drop of 1,465 m in a distance of 1,023 km (including backwater length of the Longyangxia Reservoir) is the focus of this...

Evaluation of Reservoir Seepage in Karst Topography
Areas where seepage is likely to occur in the karst environment of the proposed West County Reservoir, Roanoke County, Virginia have been indentified. Solutioning exists in the form of...

Flow Behavior of Kinked Strip Drains
Due to the often expressed concern over the axial deformation of strip drains and the resulting impact on flow rate, this study has been undertaken. A laboratory experiment has been constructed,...
