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...

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...

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...

Channel Entrenchment Along the Post Creek Cutoff in Southern Illinois
The Post Creek Cutoff was constructed in 1915 by the Cache River Drainage Commission to divert flow from the Upper Cache River to the Ohio River. The construction of the cutoff reduced...

Corps of Engineers' Mississippi River Sediment Studies
In conjunction with the 1838 U.S. Army Corps of Engineers hydrographic survey of the Mississippi River, CPT A. Talcott collected sediment samples in the passes 'to determine...

Critical Shear Stress of Armour Coat
The problem of the determination of the critical shear stress of the armour coat is important in sediment transport, river degradation and aggradation and flow discharge regulation. The...

Sediment Transport Model for Muddy Tidal Rivers
This paper describes the development and application of a one-dimensional mathematical model capable of simulating the changes to the cross-sections of a muddy tidal river over a time...

Implications of Deep Ocean Modelling on Coastal Sedimentation Prediction
The Harvard University Ocean Predictive Descriptive System is reviewed and recent results of mesoscale ocean prediction are presented for the Northeast Pacific and Gulf Stream Ring Stream...

Applications and Research in Sediment Delivery and Routing Models in the USDA-Forest Service
Sediment delivery and routing are important watershed management issues in the USDA-Forest Service. The relationship between forest management activities and stream morphology, resident...
