Natural Tracers of Coastal Sediments
The properties of natural sediments can be used to determine their sources and to trace their transport paths through coastal environments. These properties include the mineralogies of...

San Diego Regional Beach Sand Project
The San Diego Association of Governments (SANDAG) is proposing the San Diego Regional Beach Sand Project to replenish the County's beaches. SANDAG represents the Cities within San Diego...

Low Cost Sand Re-Nourishment to Combat Chronic Beach Erosion: Long Beach, California
The City of Long Beach has analyzed and attempted numerous methods of beach erosion control and mitigation along Peninsula Beach. With the exception of beach nourishment, nothing has proven...

Humboldt Beach and Dune Monitoring
Since 1881, the U.S. Army Corps of Engineers has maintained the entrance channel to Humboldt Bay on the Northern California Coast. This is accomplished through the annual dredging of approximately...

Potential Effects of San Mining and Debris Basins on Coastal Sediment Supply in Los Angeles County
The potential sediment supply to the coast in Los Angeles has been heavily impacted by human activity. In the context of rational management of beaches as a resource, it is fundamental...

Possible Sand Resources on the Reef Front Around Oahu
Large sediment deposits on the reef front around Oahu are a possible resource for replenishing eroded beaches. An overview is given on the collection of closely spaced, high-resolution...

A Whole New Experience
Experience Music Project co-founders Paul Allen and Jody Allen Patton wanted a new museum/interactive music facility for Seattle that reflected the creativity of Jimi Hendrix. In architect...

Sinking a Sewer Line
The design and construction of a sanitary sewer siphon using high density polyethylene (HDPE) pipe in San Juan, Puerto Rico, provided Black & Veatch with a challenging opportunity...

Sand Rights '99
Bringing Back the Beaches
The conference, Sand Rights '99: Bringing Back the Beaches, was organized by the Coastal Zone Foundation and the California Shore...

Blocking the Tide
The city of Venice is in peril as a result of increased tidal flooding, and a proposed system of movable gates offers the greatest promise of safeguarding the city's future....

Trenchless Transformation
The Framingham Extension Sewer (FES) was constructed of reinforced-concrete pipe in the mid-1950s as part of the wastewater collection system for the greater Boston area. Age and hydrogen...

Irrigation Method Selection Process
Intelligent selection of the irrigation method that best meets the goals and objectives of an irrigated agricultural development is of primary importance in the design process. A system...

Sprinkler Irrigation
In sprinkler irrigation, water is applied to the soil using a pressurized piping system with nozzles, jets, or perforated pipe that sprays the water into the air. These sprinkler devices...

Pipe Up
The East Bay Municipal Utility District (EBMUD) provides potable water for approximately 1.2 million people in San Francisco's East Bay area and is constructing seismic upgrades...

Guidelines for the Seismic Evaluation and Upgrade of Water Transmission Facilities
Prepared by the Technical Council on Lifeline Earthquake Engineering of ASCE This TCLEE Monograph provides guidelines for the seismic evaluation and...

Roughness Coefficients in Manning's Equation as an Estimating Tool for Bankfull Discharge in Natural Channels
(No paper) This paper compares the results of Annable's work to the roughness coefficients by stream type given in Rosgen (1994) as well as some additional coefficients from the eastern...

Stepwise Flood Routing for Gated Reservoirs and Conjunctive Optimization of Hydroelectricity Income with Flood Losses
A six-stage operation policy for routing of flood hydrographs of return periods from 1.01 year up to the Probable Maximum Flood (PMF) for dams having gated spillways is suggested. The...

Dynamic Groundwater Remediation Design with Genetic Algorithms
In groundwater remediation design it has been shown that dynamic policies, in which the pumping strategies may vary throughout the remediation period, can result in more cost-effective...

Simplification of Detailed Models of Water Distribution Systems Obtained from GIS Systems
For a long time simplified models have been used to simulate the behaviour of large water distribution networks. Often, simplification has been carried out by removing small diameter pipes...

Friction Factor Choice in Hydraulic Simulation Models: Does It Matter?
(no paper) To model water distribution systems using computer hydraulic simulation, a user is required to select a form of head loss-flow relationship for each pipe in the network. The...
