What is Necessary to Forecast River Flows Reliably?
The problem of forecasting river flows employing conceptual rainfall-runoff models is reviewed stressing the important connections that exist among data requirements, model structure,...

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...

An Emerging Application of Microcomputers in Water Control
Plans being developed at the Corps' Hydrologic Engineering Center propose a gradual transfer of water control support from minicomputers to a network of microcomputer workstations....

Role of Data Management in Water Control
The success of a system of software that must provide the water control user with current information, model analysis results, and forecasts of future behavior, is closely associated with...

Development of the Hydrodata CD-ROM Data Storage System
To store and retrieve data from two of the USGS WATSTORE databases - the daily and peak values files - and the Summary of the Day file from the National Climatic Data Center, the authors...

Optimal Operation of Complex Multireservoir Systems
The paper provides brief descriptions of papers presented in two workshop sections, and of discussions on modeling reservoir systems. The sections are on optimal operation of complex multireservoir...

Optimal Management of Multi-Purpose Reservoirs in a Hydro-Thermal Power System
Proper management of multi-purpose hydro systems requires to take into account the largely stochastic nature of water inflows, electric loads, and water demands, as well as the often conflicting...

Decision Support for Short Term Export Sales From a Hydroelectric System
A stochastic dynamic programming (SDP) model was recently developed and implemented at British Columbia Hydro and Power Authority (B.C. Hydro) to provide decision support for short term...

Real-Time Hydrosystem Operations Using Probabilistic Balancing Rule Models
A Probabilistic Balancing Rule model is presented and shown to be effective in the prescription of real-time (daily) operations for a multi-purpose surface water reservoir system. In this...

Risk Management of the Ottawa River System
The Ottawa River System is a large-scale and complex system comprising 30 major reservoirs and 43 generating stations and has a long history of flooding that extends throughout the basin....

Heuristics and Network Flow Algorithms for Multireservoir System Regulation
A generalized model employing a network flow algorithm and a heuristic database is being tested on the Qu'Appelle River basin in Canada. The heuristic database consisting...

Development of a Large Network Model to Evaluate the Yield of a Proposed Reservoir
The model simulates the operation of the Colorado River system upstream of Grand Junction, Colorado, and both the West Slope and the East Slope components of Colorado-Big Thompson system....

Optimal Operational Analysis of the Colorado-Big Thompson Project
The Northern Colorado Water Conservancy District is currently investigating the feasibility of constructing a major water storage project on the mainstem of the Poudre River for water...
