Uplift Capacity of Model Group Anchors in Sand
Small-scale laboratory experimental results for the ultimate uplift capacity of shallow horizontal circular single and group anchors embedded in sand have been presented. The experimental...
Settlement of Residual Soils
The method previously suggested by the author in 1977 for calculating settlement of non-plastic to slightly plastic Piedmont Physiographic Region residual soils is reviewed. Additional...
Investigation of Excavatability in the Piedmont
The lateral and vertical variability of rock weathering in the Piedmont presents significant problems in evaluating the probable cost of excavation for deep basements, pipeline, road cuts,...
Pressure Injected Footings in Piedmont Profiles
Comparatively little has been published on the behavior of pressure injected footings in the Piedmont residual soils and weathered rocks. It is the purpose of this paper to describe some...
Design of Drilled Piers in the Atlantic Piedmont
The philosophy and methods of drilled pier foundation design in the Atlantic Piedmont are described. Consideration is also given to the unique characteristics of decomposed metamorphic...
Drilled Piers in the Piedmont?Minimizing Contractor-Engineer-Owner Conflicts
Drilled piers are used extensively in the Piedmont Physiographic Region, deriving support primarily from end-bearing on hard rock. Cost extras and contractor-engineer-owner conflicts are...
Dispersive Soil and its Influence on the Design of Reach 1A of the Tucson Aqueduct?Central Arizona Project
An extensive geotechnical field exploration and laboratory testing program was conducted because of dispersive and erosive soils along the alignment of the canal. The canal design was...
Techniques for Delineating Subsurface Organic Contamination: A Case Study
Selection of techniques to detect and map subsurface organic contamination depends on the type of source, contamination, and hydrogeologic setting. Ideally, an investigator, manager, or...

Collective Response to Erosion Along the Nigerian Coastline
Natural factors for the rapid coastal erosion include an intense wave climate, a low coastal plain topography, vulnerable sediment or soil characteristics and, the global eustatic rise...
Properties of Tin-Mined Land in Mangrove Forest, Thailand
Although mangrove forests occupy a very small area of Thailand, they contribute not only an ecosystem but also large tin ore deposits. Two provinces in the South, Ranong and Phangnga,...
Beach Nourishment at Myrtle Beach, South Carolina: An Overview
The purpose of this paper is to summarize the Myrtle Beach nourishment project as it proceeded from the geotechnical evaluation of potential borrow sands, to permitting and design, and...
Coastal Dunes for Protection and Sand Resources
Massive mining of dune sand on the north coast of Puerto Rico has impaired the natural ability of the dunes to protect the coast from high waves and long-term erosion. This paper presents...
Stabilization of West Coast Sand Dunes
Control of dune activity and the introduction of European beachgrass have generated far-reaching effects on the West Coast landscape. Between 1900 and 1935, a series of small sand stabilization...
Foredune Management on a Developed Shoreline: Nedonna Beach, Oregon
Nedonna Beach and Rockaway Beach are adjoining oceanfront communities with foredunes that were developed before state policies went into effect. The foredunes in these two communities...
Cause and Elimination of the Deflation Zones Along the Atlantic City (New Jersey) Shoreline
