Currently Available Lake Dredging Techniques and the New Demand for Lake Sediments as a Beneficial Resource
Dredging is introduced as an effective lake restoration technique. The various techniques associated with each major category of equipment are explained. It is emphasized that large lake...
Application of the Texas A&M University (TAMU) Dredging Cost Model to Long Distance Transport
To develop intelligent decisions about moving sediment long distances to the coast from dams, the cost becomes a major factor. The cost will be a function of many factors including cleaning...
Environmentally Friendly Transport of Reservoir Sediment for Beach Nourishment with EDDY Pump
Sand impounded behind hydroelectric, flood-control and debris dams not only diminishes the intended function of the reservoir, but also starves downstream coastline by denying natural...
Regional Shoreline Group Session
California's beaches have suffered over the past decade. However to date, very little has been done to address the problem. The Sand Rights 99 conference serves as the venue for addressing...
Historical Sediment Budget Analysis of the Malibu Coastline
Sediment supply to the Malibu coastline has been continually decreasing since development began in the Santa Monica Mountains in the 1880's due to dam construction for irrigation and recreation,...
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...
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...
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...
Wireless Warnings
Formwork failures cause dozens of construction-related deaths per year, but most can be avoided by adequate monitoring. The problem is, most monitors must be hard-wired to a computer on...
Taking a New Approach (available in Structural Engineering Special Section only)
The first bridge rehabilitation project in Washington, DC to use the AASHTO Load and Resistant Factor Design (LRFD) specification reveals several lessons to be learned from using the newly...
Communicating in a Crisis
As professionals following the strictest ethical standards, civil engineers are entrusted with safety and well-being of the public, regardless of the scale or range of their designs. By...
Examining the Capitol Dome
The dome of the United States Capitol, designed and built from the 1850s to the 1860s, is a masterpiece of 19th-century engineering and construction. The majority of the dome is made of...
Design Live Loads for Parking Garages
The objective of this research project is to obtain a better understanding of parking garage live loads and to recommend an appropriate value for design. A load survey was conducted in...
Foundation Design for the Elevated Station
The Amundsen-Scott South Pole Station is located at an elevation of 2,850 m on the 3,200 m thick polar plateau, a field of ice and snow that is moving toward the ocean at a rate of 10...
Weighing Anchors
Modern anchorage systems offer design engineers and contractors unprecedented choice in load transfer mechanisms. Some anchors are highly specialized, while others are appropriate for...
Bridging Substance with Style
Engineers used an elegant form to come up with a functional solution when designing the new Damen Avenue Arch in Chicago. Two steel ribs, created using heat induction bending, closely...
Structural Surgery
Structural engineers had to transform four existing buildings and two new buildings into a new non-profit center for Jewish history. The buildings were of varying ages and had different...
