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...
Coastal Benefits and Impacts of Dismantling Matilija Dam
A numerical shoreline evolution model was used to examine the shoreline changes associated with the release of 2.3 million cubic meters of beach quality sediment from behind Matilija Dam....
Damn Sand Rights: Removing Rindge and Matilija Dams
Two dams built in the 1920's and 1940's within southern California coastal drainages have reached the end of their useful lives, and their decommissioning and removal is being actively...
Sand Rights: A Case Study of the Hamptons' Beaches
The long Federal groins emplaced at Westhampton Beach in the 1960s resulted in accelerated erosion downdrift. The severe nor'easter of December 11-12, 1992 brought the issue to a climax...

In order to undertake coastal development opportunities, the property owner must first establish the boundary between public and private property along the beachfront in order to demonstrate...
Technology in Support of Policy: The Sandag Regional Beach Monitoring Program
This paper describes a regional beach monitoring program conducted in San Diego County, California, by the San Diego Association of Governments (SANDAG). Initiated in 1996, the program...
The Economics of Our Beaches
An overview is given on the economics of beaches. Topics discussed include the role of beachfront properties in the local economy, beaches as free community open space, role of beaches...
The Beach: A Pile of Sand
Beaches are common features along most of the earth's coastlines. The presence of a beach requires at that site the processes of sediment accretion have dominated over the processes of...
Bringing Back the Beaches: A Return to Basics
California's beaches are among the state's most valuable and most intensively used natural resources. To date, although erosion is occurring in most part of California's coastline, there...
State and Federal Funding for Beach Restoration Projects
California's beaches are an integral part of its culture and identity. The state's beaches are eroding at an alarming rate. Addressing this concern, CalCoast and CSBPA co-sponsored legislation...

Hydraulics of Subsurface Flow Constructed Wetlands
Resistance to flow through subsurface flow wetlands is described by Darcy's law or by Ergun's equation. Both representations are combined with the continuity...
Siting Low Profile Grade Control Structures for the Muddy Creek Demonstration Stream Restoration Research Project
In the Fall of 1993 Reclamation began a demonstration stream restoration research project on Muddy Creek, near Great Falls, Montana. Muddy Creek captures return irrigation flow from a...
Hydraulic Effects of Habitat Structures in Flood Control Channels
Three field sites have been established and laboratory flume experiments begun to assess the effect of habitat enhancement measures on water-surface profiles and local scour in flood control...
Using HEC-RAS to Compute Scour at Bridges
HEC-RAS (River Analysis System) is an integrated system of software, designed for interactive use in a multi-tasking environment. The system is comprised of a graphical user interface...
The South Bay Ocean Outfall
For more than 60 years, raw sewage has flowed down the hills of Tijuana, Mexico into the Tijuana River, crossing the U.S.-Mexican border. The sewage contaminates the low-lying river valley...
The Effects of Water Surface Profiles on Manning's Roughness Coefficient
The Manning Equation has wide application in engineering practice. Nonetheless, certain aspects of it are still not widely understood. Often, engineers deduce the value of Manning's...
A Knowledge Based System for the Design of Open Channels
The design of open channel facilities often calls for evaluation of a unique set of physical conditions which do not lend themselves to standard designs and textbook solutions. Consequently,...
