An Expert System for Preliminary Ground Improvement Selection
Ground Improvement is an area which has rapidly advanced in the past two decades. Most of the work has resulted from experience in field work. Thus experience has played a vital role in...
Reliability in Rock Engineering
This paper reviews approaches to reliability in rock engineering through a survey of methods developed at MIT. Since these methods are intended to be applied in engineering decisions,...
Methodology for Optimizing Rock Slope Preventative Maintenance Programs
Rock slopes along transportation routes can fail in several different modes, with various types and magnitudes of consequences. The 'risks' associated with such...
Dune Maintenance
Beach nourishment and stabilization may be achieved through the replacement of sand eroded from the dune. A generalized description of the physical processes and the storm protection benefits...
Shore Protection Construction Along the California Coast
Severe beach, cliff and bluff erosion is occurring along the urban communities on the 1800 miles of ocean, bay and estuarine shoreline of California. This report is an overview of the...
Geotechnical Failure of Revetments
A calculation method is developed to analyse the stability of a granular subsoil underneath a revetment under wave attack. This method leads to a minimum revetment weight per square meter...
Geologic Controls on the Formation and Evolution of Quaternary Coastal Deposits of the Northern Gulf of Mexico
A study of the barrier islands and wetlands in the deltaic plain of Louisiana is presented. Its purpose was to document rapid changes and to learn more about the processes responsible...
Sand Bypassing at Indian River Inlet, Delaware
To solve a beach erosion problem north of Indian River Inlet, Delaware, the US Army Corps of Engineers Philadelphia District and the State of Delaware have constructed a fixed plant sand...
Processes of Shoreline Change Along the Nile Delta Coast of Egypt
A comprehensive program has been underway for more than a decade to collect nearshore data related to erosion problems experienced along the shoreline of the Nile Delta. The data include...
Implementation of Vertical Landfill Expansion
Montgomery County, Maryland, proposed to implement a vertical expansion or 'piggyback' design for the County's municipal solid waste landfill. The...
North Fork Feather River Erosion Control Program
PG&E, an investor owned gas and electric utility serving northern and central California, has been engaged since 1984 in the development and implementation of a regional erosion...
Potholes East Canal Headworks Project
The construction of 6.5 MW Potholes East Canal Headworks in Washington required near vertical excavation of about 100 ft (30 m) through the existing earthfill dam founded on columnar basalt....
The Stabilization of Minidoka Powerplant and Dam
The rehabilitation of structures can pose numerous challenges to the engineer. The structure historical preservation, the benefit cost ratio of the rehabilitation, and the stability of...
Dam Stabilization/Modification at Lighthouse Hill and Schuylerville Hydropower Developments
Remedial measures including posttensioning of concrete structures, earth dike armoring, tainter gate modification and replacement of deteriorated concrete to meet federal and state hydraulic...
Analysis and Stabilization of Ambursen Dams?Two Case Studies
Case studies are presented about the analysis and rehabilitation of two slab-and-buttress (Ambursen) dams. The paper discusses the investigation techniques used, including sampling of...
Design of Penstocks in Severe Earth Slide Locations
This paper deals with the problems of locating a penstock for a small hydroelectric plant at a site in Northern California that experiences considerable land movement during the rainy...
Penstock Monitoring System in Active Landslide Areas
During initial planning of a high-head, five megawatt hydroelectric plant in Northern California, it was identified that the entire three-mile length of a 40 inches welded steel penstock...
Application of Stable Channel Design Method
Systematic stable channel design methods are currently being developed by the US Army Engineer Waterways Experiment Station for use in the planning stages of local flood control projects....
Relationship Between Scour Depth and Bend Radius of Curvature on the Red River
Studies of bank and bend processes were undertaken on the Red River between Index, Arkansas and Shreveport, Louisiana in connection with the navigation project on the river downstream...
Riprap Design Criteria for the ARS Low Drop Structure
The ARS low drop grade control structure has proven to be an effective means to stabilize incised channels in Mississippi. However, field inspections and laboratory testing have indicated...
