Sustainable Management of Existing Reservoirs
Instead of a design and planning of new reservoirs in the future, more emphasis will be placed on the management of existing reservoirs. Reservoir storage reallocation and reassessment...

Design Considerations for Night Storage in Irrigation Systems
Due to the farmer social and economical changes, irrigation during night became rare. Most of the night discharges flow to drains. A design procedure has been developed for storage in...

Involving the Public to Reach Consensus in Water Resources Projects - An Interdisciplinary Perspective
The San Diego County Water Authority (Authority) is developing the Emergency Storage Project (ESP) to improve the reliability of the county's water supply in the event of an extreme emergency,...

Development of an Intergovernmental Agreement For a Major Multi-Party Recharge Project in Central Arizona
The Salt River Project (SRP), a major power and water utility in the Phoenix area, and several municipalities recently completed the development of an intergovernmental agreement (IGA)...

Reoperation of Existing Reservoirs to Serve Changing Needs: Observations on Institutional Inertia, Conflict, and Efficiency
The 'reoperation' of a reservoir system may in some circumstances provide a non-structural alternative for addressing changing water storage needs resulting from population growth or other...

Aquifer Storage and Recovery at the Centennial Water and Sanitation District
water in a suitable aquifer, the peak time capacity of CWSD could be increased while delaying the water treatment plant (WTP) expansion currently scheduled for 1996. To validate this assumption,...

The Scottsdale Water Campus: There's Nothing Like It
The Scottsdale Water Campus will house facilities to effectively enhance the management of the City's Water Resources in the central and northern section of the City. Wastewater generated...

Missouri River Least Tern and Piping Plover Model Development
As part of the update of the Missouri River Master Water Control Manual, the U.S. Army Corps of Engineers is evaluating the effects of numerous water management alternatives on endangered...

Using A Risk-Based Relative Position Analysis to Initiate Water Conservation Measures
When water utilities operate with annual demands close to safe yield, they must be prepared to invoke water conservation measures during droughts to assure adequate supply. Determining...

Wastewater Reclamation at Davenport, Washington
The City of Davenport, Washington went through an extended process to update their undersized wastewater treatment and irrigation reclamation systems for municipal wastewater. The process...

San Diego County Water Authority's Emergency Storage Project Supplying Water During Natural Disasters
The San Diego County Water Authority (Authority) is developing the Emergency Storage Project (ESP) to improve the dependability of the County's water supplies during a natural disaster...

Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...

The Use of SCADA for Real-time Calculation and Monitoring for CT Compliance at the Ralph D. Bollman Water Treatment Plant
The contra Costa Water District (CCWD) of Concord, CA was formed in 1935 under the authority of the State Water Code. CCWD purchases its water supply from the Central Valley Project (CVP),...

Settlement of Tanks on Clay
Steel tanks for storage of water, oil, and other liquids are capable of withstanding large, but not unlimited, settlements without damage. In most cases shallow foundations provide adequate...

Performance of Oil Storage Tanks on Vibroflotation Improved Hydraulic Fill in the Port of Tampa, Florida
The paper describes a case history of design, construction and performance monitoring of two 80,000 barrel oil storage tank foundations 35 meters in diameter on a soft hydraulic fill soil...

Performance of a Steel Tank Founded on a Marine Clay
For tanks on soft clays, the soil is often preloaded before tank construction to increase bearing capacity and minimize post-construction settlement. In the case history described here,...

Performance of Three Large-Diameter Oil Tanks on Soft Clay
Preloading using a clay surcharge at the proposed locations of 3 large-diameter steel oil storage tanks founded on a 20-m thick stratum of soft Nile-delta silty clay produced about 1.5...

Application of Numerical Models in the Design of Clarifiers
In this study, a numerical model of a circular clarifier was applied to reveal the effects of the water depth on the hydraulic and removal efficiency. The velocity and solids concentration...

Trihalomethanes in Chlorinated Sacramento-San Joaquin Delta Drinking Water Simulated with the EPA WTP-THM Model
Trihalomethane (THM) concentrations at a representative water treatment plant simulated with the EPA Water Treatment Plant THM (WTP-THM) model were used to assess potential drinking water...

Quasi-Two Dimensional Modelling of Flood Routing in Rivers and Flood Plains by Means of Storage Cells
A quasi-two dimensional numerical model for flood routing in rivers and flood plains has been developed. In the river, the St Venant equations are integrated using the implicit finite...
