Model to Maximize Releases for Supplemental Generation in a Pump-Storage System
An optimization model has been developed to maximize releases for supplemental power generation in a pump-storage system. The model was developed to aid in the scheduling of pump-storage...
Transferring Conserved Water
The proposal to transfer water salvaged by water conservation programs from one area to another is a new concept. Imperial Irrigation District (District), located in the southeast portion...
Interstate Agreements for Water Transfers
Any state is typically subjected to opposing forces that wish to 1) preserve limited water resources for future in-state uses, or 2) to export that resource for out-of-state use. Statutes...
Corps of Engineers Automation of Real-Time Water Control Management
Automation of real-time water control management activities has enabled the Corps to keep pace with an ever increasing workload in a time of fiscal constraint and reduced manpower. Where...
Sedimentation Problems of the California Aqueduct
The California Aqueduct crosses the alluvial fans of many intermittent streams on the west side of the San Joaquin Valley. At two sites where watershed sediment yields were underestimated,...
Sedimentation in the All-American Canal
During the planning for the All-American Canal, by the U. S. Bureau of Reclamation as part of the Boulder Canyon Project, works were designed at the head of the canal to remove between...
Uncertainties in Groundwater Transport Modeling
Using synthetic data from a hypothetical aquifer, the effects of data availability and data uncertainty were studied by the combined use of a parameter identification (PI) algorithm and...
Estimation and Inference in the Inverse Problem
The estimation of groundwater flow and mass transport parameters is approached via maximum likelihood. Confidence intervals and hypothesis tests as well as the asymptotic properties of...
A Robustness Constraint for the Analysis of Uncertainty
A sensitivity-based definition of system robustness is presented that can be formulated as a constraint within an optimization framework. The optimization framework permits the tradeoffs...
Oxygenation of Releases from Richard B. Russell Dam
The oxygen injection system at the Richard B. Russell project has a continuous injection system located 1 mile upstream of the Russell damsite but also has supplemental injection capability...
The Reliability of Treatment Systems
The purpose of this paper is to present the results of case studies of zero and first order reactor systems and an activated sludge treatment system consisting of a primary settling tank...
On-Site Microcomputer Control of a Combined Sewer Overflow Diversion Structure
This paper describes the design of an inexpensive system for controlling combined sewer overflows using on-site equipment (raingauges, flow gauges, automatic gates, and microcomputers)....
Computer-Aided Analysis of Treatment Plant Hydraulics
This paper describes software for the hydraulic analysis of water and wastewater treatment works. HADES (the Hydraulic Analysis, Design, and Evaluation System,) provides interactive analysis...
Real-Time Monitoring and Flood Forecasting
An automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 150 sensors are automatically...
Heppner's User-Friendly Local Flood Warning System
The Heppner, Oregon, local flood warning system uses state-of-the-art technology with event-initiated data transmission, real-time monitoring, and automatic evaluation and notification....
Water Supply Infrastructure Needs: The Evolving Picture
Based on the findings from AWWA surveys conducted in 1983 and 1985, it appears that the earlier conclusion that the needs of the nation's water systems can be met by the local...
Financing Water Supply Infrastructure - A Public Works Perspective
The Massachusetts Water Resources Authority was established to ensure that the regional water and wastewater needs were properly addressed, removing the budget process from the legislature...
The United Kingdom Approach to Rehabilitation
Following concern over the condition and performance of its underground assets, the UK Water Industry has developed strategies for cost effective sewer and water main rehabilitation. These...
Water Infrastructure: Research and Education Needs
Problems with infrastructure have received considerable attention but not much has been written about implications for research and education. Education and research should be aimed at...
Verification of a Supply Reliability Model
Three versions of an analytical model for estimating the reliability of a water supply system including capacity components and small amounts of finished water storage are presented. Simplifying...
