Expert System for the Preloading Method of Ground Improvement
Design practice of the preloading method, which is one of the ground improvement techniques, applied for the hydraulic fill area includes quite complicated problems, especially when draining...
Deriving Alternative Structural Modifications Based on Qualitative Interpretation at the Conceptual Design Stage
Current computer tools provide little support in deriving alternative modifications based on qualitative structural interpretation of a conceptual design. This paper presents a behavior-based...
Application of Spencer's Method for Slope Stability Analysis
For slope stability analysis with general, arbitrarily shaped failure surfaces, the Spencer's method has been found to provide a reasonably accurate result. This method satisfies both...
High-Tech Landfill Caps
Just as federal and state regulations detail every aspect of landfill location, construction and operation, they now detail every aspect of its design closure. A typical municipal solid...
Maglev Guideway Route Alignment Parameters
Passenger comfort at high maglev vehicle speeds (110 to 134 meters per second) has significant impact on the proposed use of the existing highway and railroad rights-of-way for hosting...
Streambank Inventory and Protection Soldotna Reach, Kenai River, Alaska
This paper discusses bank conditions found along the Kenai River within the city of Soldotna in Alaska. River banks were inventoried in May 1990 by USDA Soil Conservation Service (SCS)...
Plant Establishment Enhancement Technique for Shoreline Stabilization and Protection
Once established, vegetation is capable of significantly reducing erosion along streams, rivers, bays, sounds and other tidal shorelines. In the last 15 years, many attempts to establish...
Sand Management Planning in Oregon
Under Statewide Planning Goal 18 dune grading or sand movement necessary to maintain views or prevent sand inundation is allowed only as part of an area-wide foredune management plan....
Evaluation of Plants for Coastal Dune Stabilization
The dune stabilization system used in the Phoenix Condominiums project can be used to enhance dunes all along the Atlantic and Gulf Coast. The plants and technology are available, which...
The Marine Mammal Health and Stranding Response Program
A National Marine Mammal Tissue Bank (NMMTB) has been established as part of a comprehensive effort to obtain reliable information on contaminant levels in marine mammal tissues. A four...
DUNECARE: Healing the Coast
DUNECARE is active community participation in environmental restoration. This document reports on the operation of the DUNECARE programme in coastal New South Wales, Australia. A Model...
A Method for Classifying Land Loss by Geomorphology and Process
There is great debate as to the causes of land loss in Louisiana and the restoration/preservation solutions that should be implemented. Much of the controversy can be attributed to a lack...
Bank Erosion at the Aransas National Wildlife Refuge
The Aransas National Wildlife Refuge has been experiencing problems with the erosion along the banks of the Gulf Intracoastal Waterway. In order to prevent future erosion it is necessary...
Case Studies for Coastal Protection: Dithmarschen; Eider Estuary; Sylt
Three cases along the Ger North Sea coast, north of the Elbe estuary are discussed. Land reclamation by building dikes started in the Dithmarschen-area almost eight hundred years ago....
Characteristic of the Yellow River Delta
The yellow river delta is a most unstable delta in the world. The river burst its lowstream bank 1500 times during the last 3000 years, 26 large shifting of the channel as well. The river...
The Planning and Design of Multipurpose Artificial Barrier Reefs
Multipurpose artificial barrier reef is proposed for the enhancement of fisheries as part of the purpose of entire system of structures in Japan. As part of our planning efforts we are...
Travel Time in Mountain Basins
An empirical relationship is developed for estimating travel time in high gradient stream channels with natural beds of large gravel, cobbles and random boulders and which are flowing...
Sediment Entrapment by Stream Channel Vegetation
Degraded headwater streams are common in the mountainous West. They have experienced a variety of stresses from public and private uses and will require specific management consideration...
Primary Metals and Criteria for Water use in the Columbia River, British Columbia
We assessed primarily concentrations of lead, cadmium, copper, zinc and water hardness in the Columbia River between Birchbank and Waneta. Water quality in this reach of the river is affected...
Stable Slopes of Alluvial Channels
An alluvial channel responds to the variation in the incoming sediment by changing its cross-section and especially the slope. Regime relations formulated by Lacey (1930) and many subsequent...
