Geotechnical Judgment in Foundation Design
This paper summarizes the initial findings of a research project to investigate the judgment-making process of foundation engineers. Solutions for a typical design problem were solicited...

Structural Foundation Practices for Highway Projects
The state-of-practice by State transportation agencies, in the area of structural foundations, is compared between the late 1970's and the present. The structural foundation...

Interaction of Geology, Construction Practice and Foundation Design
The influence of geologic knowledge and construction practices on the geotechnical foundation design process has been assessed and summarized. Particular emphasis has been given to the...

Chemically Induced Foundation Heave
The Kerr-McGee Electrolysis Plant in Henderson, Nevada has had recorded upward movements of portions of the building in excess of 18 inches. Contours of the measured heave indicate that...

Cokriging for Evaluating Agricultural Pollution
Subsurface drainage data from irrigated lands near Twin Falls, Idaho were used. Total Dissolved Solids and NO3-N were selected as variables. The...

The Influence of Water Tables on Herbicide Losses
Atrazine and metolachlor were applied preemergent on April 22, 1987, to silage corn on high watertable fields which were either subsurface drained (104 mm drain tubes 1 m deep) or surface...

Safer Dams
During the last 11 years, thousands earth dams have been inspected. Here are four that were rehabilitated. Army Corps inspections are phase I of the program, and have been completed. The...

Evaluating Sinkhole Hazards in Mantled Karst Terrane
Sinkholes are the most serious geologic hazard in karst terrane because they can damage structures, drain ponds and lakes, and allow direct infiltration of groundwater contamination. The...

Exploration of Karst Conditions in Central Florida
Walt Disney World, which comprises some 28,000 acres (11,000 ha) in central Florida, is underlain by cavernous limestone and is characterized by karst topography; with distinct low ground...

Exploring Karst Terrain with Air Track Drilling
Pneumatic-powered track-mounted, percussion drills can be used to perform or augment geotechnical investigations in some karst settings. The air track drill is best suited to exploring...

Karstic Foundation Problems Sunny Point Railroad
Active limestone sinkholes have been causing problems and affecting the operation of the access railroad to the Military Ocean Terminal, Sunny Point, North Carolina (MOTSU) since 1962....

Irrigation Intervention Analysis of Drainage SAR
G.E.P. Box-G.M. Jenkins time series analysis, with irrigation applications as an intervention function, was used to study temporal and spatial variabilities of sodium adsorption ratios...

Investigation of Runoff from a Subsurface Drained Field
This paper examines the relationship among rainfall, water table level and runoff hydrographs for subsurface-drained farmlands. It was found that peak flows were greatly influenced by...

Atrazine in Subsurface Drain Water in Southern Louisiana
Atrazine was applied preemergent to corn on subsurface drained and undrained plots. Atrazine soil concentration and concentration and loss in drain water were determined for 243 days after...

Trace Elements and Pesticides in Salton Sea Area, California
Concentrations of numerous potentially toxic trace elements and pesticides were determined in water, sediment, and biota from the Salton Sea area in southestern California. Comparison...
