Two Options for Disposal of Desalination Reject Water
A major problem associated with the use of desalination plants for the production of fresh water is the disposal of the reject water. This water is typically double the salinity of the...
A Diffusion Hydrodynamic Model of a Shallow Estuary: Verification
Many of the hydrodynamic models used for estuary tidal flows and storm surges are based on two two-dimensional hydrodynamic equations which are obtained form the full three-dimensional...
Analysis of Local Scour at Bridge Piers
Many studies have been performed on the cause and effects of local scour at bridge piers, and various prediction equations have been generated based on these studies. The general approach...
Hydraulic Performance of a Flexible Curtain Used for Selective Withdrawal ? A Physical Model and Prototype Comparison
Reclamation (U.S. Bureau of Reclamation) studied a 1:120 scale undistorted density stratified physical model to develop a lightweight flexible curtain barrier that would control the outflow...
A Flexible Curtain Structure for Control of Vertical Reservoir Mixing Generated by Plunging Inflows
To maintain salmon habitat in the Sacramento River, efforts are being made to pass cold water inflows through Whiskeytown Reservoir, California, with minimal warming. In Whiskeytown, summer...
Sacramento River Environmental Requirements
Environmental requirements have altered bank protection engineering and construction on the Sacramento River, California. Conflicts between public safety and environmental protection remain...
Concrete Pipe for Sanitary Sewers Corrosion Protection Update
Significant advances have been made in the last decade in the area of sanitary sewer design techniques. Some of the most important advances have been in the prediction and prevention of...
Analysis and Design of Direct Burial Sections of San Diego County Water Authority's Pipeline 4 Extension
The pipeline 4 extension is one of the San Diego County Water Authority's Phase I projects that will run for about 13 miles. Majority of this new pipeline will be 96 inch in steel and...
Proactive Odor Control Using Computer Modeling
The City of Los Angeles (City) is currently designing the East Central Interceptor Sewer (ECIS) as a major relief sewer. The pipeline will convey wastewater flows that originate upstream...
CALTRANS Seismic Hazard/Risk Map and Proposed GIS Applications
The California Department of Transportation (CALTRANS) considers earthquake effects in planning, design, and construction of their structures. Obviously, CALTRANS has to respond to damaging...

Pricing Armor Rock for Rubble Mound Breakwaters
The pricing of armor rock by breakwater contractors is an inexact exercise. Each breakwater project is so site specific that standard costing methods are difficult to apply. The wide range...
Articulating Block Mat Revetment for Whaler's Village
The desire of homeowners to live along the California coastline presents the engineer with many unique design opportunities and constraints. Housing built atop coastal cliffs and bluffs...
Design, Construction, and Performance of a Baffled Breakwater
The Spud Point Marina breakwater is located within Bodega Harbor, a protected embayment on the northern California coast. Waves are attenuated by baffle panels hung between support piles....
The Talbert Channel Ocean Outlet Project
The Talbert Channel Ocean Outlet Project consisted of relocating and enlarging the outlet of a relatively narrow, shallow flood control channel in Southern California. Noteworthy aspects...
Design Considerations for Small Artificial Islands in Franks Tract, California
Small, artificially-created islands may provide significant recreation and habitat benefits. Costs, however, can also be high. The initial dollar cost of creating an artificial island,...
Environmental Constraints Associated with Dredging in Southern California
