Design and Construction of the Pier J Breakwaters at the Port of Long Beach, California
Several different alternatives to mitigate surge activity were investigated. The most acceptable solution was a pair of new breakwaters that altered the basin geometry to change the basin...

Construction Factors and Monitoring Methods Relating to the Performance of Ventura Breakwater Core Loc Repair
In 1999 the Los Angeles District of the U.S. Army Corps of Engineers (USACE) repaired the north Ventura breakwater head. The head was rebuilt using 2-ton underlayer stone armored with...

An Aggressive I/I Abatement Program is Underway as Part of Vallejos Wet Weather Program
The Vallejo Sanitation and Flood Control District (VSFCD) is undertaking an aggressive pilot program to control wet weather flows and eliminate sanitary sewer overflows (SSOs) that are...

Turbulence, Bottom Boundary Conditions, and Sediment Transport in a Shallow Water Habitat
Field experiments were designed to explore the effects of vegetation on the hydrodynamics and sediment transport in Franks Tract, a shallow water habitat in the Sacramento-San Joaquin...

Sediment and Nutrient Monitoring and Modeling in Lake Tahoe Basin, California, U.S.A.
The water quality of Trout Creek, South Lake Tahoe, California is monitored to assess the system's response to stream restoration. It is the principal endeavor to conduct a systematic...
