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...

Water Reclamation Potential in Southern California to the Year 2010
This is a summary of plans and projections for future water recycling by Southern California public and private water and sewerage agencies involved in water recycling. The central purpose...

Reducing Discharges from San Francisco to the Bay
The City and County of San Francisco (City) is fairly unique in the west because it has a combined sanitary and storm water system. When the current Wastewater Master Plan (WWMP) was completed...

Opportunities, Constraints and Change in Reservoir Management
Changing hydrologic, economic, social and environmental conditions have focused attention on the opportunities for changing reservoir management. Such change can occur in three areas....

A Salmon Population Model for Evaluating Alternative Flow Regimes
Salmon populations in many Pacific coast rivers are in decline and in danger of becoming threatened or endangered. A fish population model that tracks chinook salmon from eggs to the immature...

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...

Seismic Evaluation of the Macy Street Bridge, Los Angeles, California, Using 3-D Nonlinear Pushover Methodologies
Nonlinearity of the overall bridge response has begun to be incorporated in the design process through a method known as nonlinear static pushover analysis, and this step is now being...

Nonlinear Analysis and Experimental Validation of a Stiffening Truss Chord of the Golden Gate Bridge
Finite element analyses of a stiffening truss chord of the Golden Gate Bridge were conducted by the authors as part of a comprehensive seismic retrofit project conducted by T. Y. Lin International...

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 Deep Compacted Fills in California
Measured settlement of deep compacted engineered fills from a single site were summarized and compared to data from other sites. The data indicate that the rate and magnitude of movement...

Soil Improvement to Mitigate Settlements under Existing Structures
Settlements of sites with existing structures are more difficult to mitigate than those of sites without structures. Equipment access, work area, noise, dust, vibrations, and cost are...

Modifying One of the Nation's Most Successful Biosolids Lime Stabilization Operations
Since 1978, the Vallejo, California, Sanitation and Flood Control District has managed a tremendously successful biosolids program consisting of lime stabilization and agricultural land...

Pilot Test on Groundwater Organics Removal by Low-Pressure Membranes
A 1-year membrane pilot study has been performed to evaluate disinfection-byproduct (DBP) precursors and color removal by low-pressure membranes from groundwater with color values up to...

Evaluation and Management of Non-Point Source Pollutants in the Lake Tahoe Watershed
Lake Tahoe, California-Nevada, one of the most oligotrophic lakes in the world, is experiencing decreased water clarity and increased periphyton growth, and water supplies drawing from...

Modeling Pollutant Fate and Transport in Constructed Wetlands
The Constructed Wetlands Fate and Aquatic Transport Evaluation Model (CWFATE) was developed to evaluate alternative design and operations of the constructed wetlands treatment system (CWTS)...

Predicting the Impact from Significant Storm Events on a Hazardous Waste Site
The Stringfellow Hazardous Waste Site is a former Class I industrial waste disposal facility located near the community of Glen Avon in southern California. In response to community concerns...

Observations on the Growth of an Internal Boundary Layer with a Lidar Technique
The distribution of atmospheric water vapor across a step change in surface humidity (dry-wet) was observed by a Lidar measurement technique under neutral atmospheric stability condition....

Expert Analysis in Regulated Irrigation Canal Modelling
Application of riverine unsteady-flow numerical modelling techniques to problems of flow regulation in irrigation canals invokes the need for careful treatment of some situations not commonly...

Hydrodynamic Modeling of San Diego Bay
A two-dimensional vertically-averaged finite element model was adapted to study the hydrodynamics of San Diego Bay. The hydrodynamic model was interfaced with pre- and post-processors...
