Dynamic Effect of Sediment on Dam Hydrodynamics
The dynamic behavior of reservoir sediment during earthquakes is important to an analysis of dam safety when the depth of the water is seriously reduced by the sediment. While the dynamic...

An Innovative Institutional Arrangement Which Incorporates the Risk Preferences of Water Users
An innovative institutional arrangement that incorporates the risk preferences of water users is being refined in Australia. It is especially relevant for river and reservoir management...

Maximum and Minimum Storage Trajectories That Meet Specific Risk Levels
One of Hydro-Quebec concerns is to operate its installations so as to satisfy the operating constraints. This paper describes a mathematical tool that enables the utility company to state...

Agricultural Drains and Safety of Dams
Bonny Dam is located in east central Colorado on the South Fork Republican River. The dam's foundation is in the relatively porous Ogallala formation. Throughout the history of the dam,...

Operation of the Tennessee Valley Authority Water Control System Under Extreme Drought Conditions
The Tennessee Valley region recently suffered through the most severe drought of record. As increasing demands were placed on the reservoir system, operating priorities were modified to...

Global Climate Change Effects on Water Quality
The annual thermal energy cycle of Shasta Reservoir in California is simulated under scenarios of climate corresponding to present conditions and as predicted by global climate models...

Rock Creek?Cresta Sediment Management Plan
Pacific Gas and Electric Company (PG&E), an investor owned utility serving northern and central California, is working to manage sediments at its Rock Creek - Cresta Hydroelectric...

Water Supply Operations During Drought
During years when water supply may not be adequate to cover water demands, water supply decision maker or managers need to decide how to spread projected shortages through the anticipated...

Planning and Operation of a Multi-Reservoir Water Distribution System
A water supply distribution system planning model (DSPM) is developed using a directed graph algorithm as its pre- and post-processors and a linear programming (LP) procedure as an `intelligent'...

Reservoir Operating Rules for Maximum Hydropower Production
A procedure for testing the effectiveness of reservoir operating rules for real-time, multi-purpose reservoir operation is presented. Particularly, models that may be used to achieve maximum...

Development of Storage Demand Relation for Reservoirs?A Probabilistic Approach
This paper presents a practical method for developing storage-demand relation for reservoirs by a probability analysis of the stream flow data. The method was employed by the author for...

Prescriptive Model for Missouri River Reservoir-operation Analysis
The six main-stem reservoirs of the Missouri river system are operated by the Corps of Engineers for flood control, navigation, irrigation, power, water supply, water quality control,...

A Demand Driven Decision Support System for Operation of Reservoirs
In this paper a stochastic optimization model, called Demand Driven Stochastic Dynamic Programming (DDSP) is developed and is compared with a Bayesian Stochastic Dynamic Programming (BSDP)....

Reservoir System Reliability Constrained by Natural Salt Pollution
A generalized reservoir system simulation model, which incorporates salinity considerations, has been developed and is presently being applied to a system of 12 reservoirs in the Brazos...

Development of a Phase I Prescriptive Reservoir Model
The U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC) has recently developed a Phase I generalized prescriptive reservoir model referred to as HEC-PRM. The purpose of the...

Managing Existing Reservoirs to Meet New Challenges
The current planning and management environment for many reservoirs differs significantly from the situation which existed when the projects were initially planned and constructed. Yet,...

Reservoir Water Quality Modeling in Northern Portugal?Some Case Studies
In the last two decades environmental problems have become a major concern in Portugal as the effects of water pollution have gradually impaired the quality of water resources. Mathematical...

BRASS Modeling of Lo?za Reservoir, Puerto Rico, for Sediment Management Operations
Loiza reservoir, the principal water supply for metropolitan San Juan, delivers 3.5 m3/s (80 mgd) to the Sergio Cuevas filter plant. Sedimentation...

Expert System for Operating A Treated Water Supply System
This paper presents a systematic approach to the development of an expert system to operate a treated water supply system for meeting daily water requirements. A treated water supply system...

Offshore Structures?Past, Present, and Future
A review of the evolution of offshore platforms concludes that the process is ongoing. New configurations continue to emerge and the range of applicability continues to expand. Today's...
