Short-Term Hydroelectric Scheduling Model for WAPA
An optimization model, data system, and a series of user-friendly input/output screens (the HYDRopower Optimization Program, HYDROP) have recently been implemented at the Loveland Area...

Utilization of the Ottawa River Regulation Modeling System (MORRO)
The MORRO model was developed in Canada for use by the Ottawa River Regulation Planning Board (ORRPB) to integrate the operation of the Ottawa River during the spring freshet season, when...

Alternative Methods of Generating Hydrologic Data for Reservoir Optimization
Given an historically based set of natural flows for the Colorado River at Lees Ferry, a series of 16 indexed sequential traces 78 years in length were derived using a 'wrap around' approach...

Application of Principal-Component Analysis to Long-Term Reservoir Management
Determining the optimal long-term operating policy of a multireservoir power system requires solution of a stochastic nonlinear programming problem. The paper presents a very efficient...

Computerized Decision-Guidance System for Management of the Trent River Multireservoir System
A computer simulation model has been implemented for a complex multireservoir system, composed of 44 reservoirs and 52 channels. The model is designed in modular form to forecast inflows,...

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....

City of Roseville, California, Alert System: Real Time Microcomputer Based Flood Warning System
The ALERT system was developed by the California-Nevada River Forecast Center of the National Weather Service. The System integrates self-reporting, field sensors, a base station microcomputer,...

Flood Warning Using Wide-Area Computer Networks
Wide-area computer networks are being used with increasing frequency to improve regional response to flood events, coordinate efforts between agencies and communities, and to improve flood...

Flash Flood Hydrologic Forecast Model, ADVIS
The Flash Flood Hydrologic Forecast Model, ADVIS, is the computer replacement of manual forecast procedures using tables. This interactive forecast model computes a crest forecast, plots...

Hydrologic and Institutional Water Availability
A simulation study was performed to evaluate the amount of water which can be supplied by a system of 12 reservoirs located in the Brazos River Basin. The generalized computer models HEC-3...

Meeting Environmental Commitments at Power Plants Using Real-Time Reservoir Scheduling
This paper describes two different real-time modeling systems that determine if scheduled hydro releases will affect meeting environmental commitments. The modeling system for John Sevier...

A Tale of Two Subjects: Modern Physics and River Mechanics
The Einsteins, father and son, made some of the greatest contributions to physics and to river mechanics, respectively. The modern phases of these two subjects are of roughly equal age....

Total Sediment Transport and Its Physical and Mathematical Modeling
Some main results in the field of sediment transport theories obtained by the author are presented. Based on these theories, the methods of physical and mathematical modeling for total...

Quasi-2D Transport and Morphological Forecasting in Large River Systems
Unused potentials of 1D morphological, and transport models were applied to predict not only the longitudinal but also the transverse distribution of concentrations and natural river bed...

The Formation of Meandering and Braided Channels
Flow in alluvial channels implies flow past boundaries that form and deform under the action of the flow. Interaction between the flow and the mobile boundaries produces channel patterns...

Bed Waves Generated by Internal Waves in Alluvial Channels
The flow in an alluvial channel is conceived as a stratified flow both with respect to the velocity- and density-distribution. In such flows internal waves may occur which influence the...

Modeling of Contaminant Transport in Rivers with Emphasis on the Interaction with Movable Boundaries
The transport of dissolved and absorbed pollutants is simulated by a one-dimensional convection-diffusion model which particularly accounts for the exchange processes at the river bed...

Comparison of n Values in Natural and Dredged Channels
Manning's n values were determined for three stream channels in two complex watersheds in North Mississippi. The study covered a wide range of channel conditions and flow...

Derivation of a Stability Principle from the Shields Criterion
The widely used specific energy equation, which defines the subcritical and supercritical states of the open channel flow, is a direct result of the integration of the Froude number corresponding...
