On the Problem of Sediment Deposition in Large Reservoirs
Sediment deposition and its accumulation in a large reservoir depends on the inflow and reservoir storage content, respectively. This fact is used to model the cumulative deposition of...
Status and New Capabilities of Computer Program HEC-6: Scour and Deposition in Rivers and Reservoirs
Last year the Hydrologic Engineering Center (HEC) and the Waterways Experiment Center (WES) incorporated the results from more than ten years of research and development into a new version...
An Expert Advisor for Selective Withdrawal Operations
A rule-based computational advisor that aids in the selection of selective withdrawal operations for project release temperature maintenance is discussed. This advisor couples a one-dimensional...
Corps of Engineers Sediment Management Program
The existing sediment management program includes sediment investigations of reservoir, river and levee projects; gathering and maintaining sediment load records; providing sediment investigation...
Major Sedimentation Issues and Ongoing Investigations at the Federal Energy Regulatory Commission
There generally exist five types of sedimentation problems. These are watershed, stream, reservoir, estuary and coastal problems. At the Federal Energy Regulatory Commission's...
Measurement of Hydraulic and Environmental Effects of Aeration Devices in Douglas Reservoir
The releases from Douglas Reservoir experience periods of low dissolved oxygen (DO) content during the summer months. Tests were conducted during August 1989 to determine the effects of...
Diversion Closure Gate Schemes Used on B.C. Hydro Dams
Over the last 25 years B.C. Hydro has designed, built and has operated a number of large dams and continues to do so. This paper describes the design, erection and operating experiences...
Corps of Engineers Drought Management Experiences
The drought of 1988-89 was one of the most severe on record for many regions of the United States. Its severity can be measured in terms of the areal extent of hydrologic impact, the record...
Building in Reservoirs
The Croton Supply System, one of the three major water supply systems for New York City, is undergoing extensive rehabilitation. In an innovative use of space, some of the new construction...
Dams Reborn
The need to rehabilitate dams without draining their valuable reservoirs is impacting the way the Bureau of Reclamation makes modifications. There are no two better examples of this than...
Generation of Multiple Tier Instream Flow Requirements
Multiple tier scaling of instream flow requirements based on available water supply and reservoir storage state is proposed as a means of generating instream flow regimes. Rules for variable...
Training Water Delivery System Operators with Simulators
A graphical display training simulator has been developed on a microcomputer to mimic the operation of a multi-reservoir water delivery system. The simulator functions as a training device...
Savannah River Basin Drought Contingency Planning
Beginning in 1986, and continuing through the present time, the worst drought in recent history created severe water shortage conditions over extensive areas of the southeastern United...
Computer Support for TVA's Reservoir System Operations: Hardware
The current computer systems in use at TVA for hydrologic data collection and modeling are approaching ten years old. A study is in progress to determine the computer systems needed to...
Computer Support For TVA's Reservoir System Operations: Software
In the early 1980's, the Tennessee Valley Authority implemented its Water Resources Management Information (WATREMAIN) system to provide support for operation of its integrated multipurpose...
OMADSS?Operations and Maintenance Advanced Decision Support System
This paper presents a summary of the development of a prototype advanced decision-support system for operation and maintenance of dams and irrigation facilities. To set the development...
Stochastic Evaluation of Reservoir Operation Rules
The major water facilities in California encompass the State Water Project, operated by the State of California, and the Central Valley Project, owned and operated by the United States...
Limitations of Level-Pool Routing in Reservoirs
Storage routing is defined for purposes of this study as any routing technique which expresses reservoir storage as a single-valued function of stage, and hence it is sometimes termed...
Channel Routing for Improved Flood Control
Lake Wappapello, located on the St. Francis River in southeastern Missouri, is operated by the St. Louis District (SLD) Corps of Engineers for purposes of flood control and recreation....
Operational Forecasting in Complex River Basins with SSARR-Micro Versus Mainframe Computer
The Streamflow Synthesis and Reservoir Regulation, (SSARR), model has been used for many years for river forecasting and reservoir system modeling in the Columbia River Basin. Operational...
