Creep of a Strip Footing on Ice-Rich Permafrost
Creep settlement tests were performed on a strip footing founded on the surface of ice-rich aeolian silt permafrost. The tests consisted of applying four step loadings to a 10 in. (25....
Case Histories: Evaluation of Drilled Pier Integrity by the Stress Wave Propagation Method
The Stress Wave Propagation Method (SWPM) was used to nondestructively investigate the integrity of straight-shaft drilled pier foundations at two sites in the Denver, Colorado area. Drilled...
Predicted and Measured Performance of a Foundation
The predicted and measured short term foundation behavior of a 28 story building in downtown San Antonio, Texas is reported. The soil is a stiff to hard clay and clay shale. The design...
Geotechnical Behavior of Underreams in Pleistocene Clay
Enlarged bases are often constructed in cylindrical drilled-and-cast-in-situ foundation elements (footings, bored piles) to increase their capacity. Enlarged bases that are cut mechanically...
Comparison of Caisson Load Tests on Chicago Hardpan
The results from two relatively recent instrumented caisson load tests from different sites on Chicago Hardpan are compared with a 'classic' large scale caisson...
Quality Management in the US Army Corps of Engineers: An Evaluation
Quality management programs are employed to assure the achievement of specific standards of performance. In the construction industry, quality management personnel face common problems...
Construction Management: Dallas North Tollway Project
This article will attempt to illustrate the importance of flexibility of the design and construction inspection process to insure the project is constructed within the time and budget...
An Ecosystem Approach to Watershed Management
An example is drawn from the Little River Research Watersheds near Tifton, Georgia. Riparian hardwood forests (low management) and upland agricultural fields (high management) are the...
Tools for Managing Army Training Lands
Army land managers and planners are responsible for managing large, diverse parcels of training land for sustained use. The highly variable but often destructive training requires a systematic...
Chaparral Watershed Management: A Systems Approach
The predicted environmental and economic effects of partial chaparral conversion for increased water yield on an experimental watershed in the Prescott National Forest, Arizona, are examined...
Mass. Municipal Watershed Management?Case Study
Most of the estimated 200,000 acres of municipally-owned watershed land in Massachusetts currently suffers from a lack of wise, multiple-use forest management which has resulted in lost...
An Annual Water Balance for a Surface Mining Overburden Waste Embankment
The embankment contained a volume of 257 thousand cubic yards and resulted from a phosphate surface mining operation in southeastern Idaho. The elevation of the embankment is about 7500...
Simulation of Hillslope Hydrologic Response to Snowmelt in Southwestern Idaho
A two-dimensional, variably saturated porous media flow model was applied to vertical hillslope cross section on a first order study basin in southwestern Idaho. The dominant source of...
Modeling Streamflow Response from Minnesota Peatlands
A deterministic, continuous simulation model was developed to predict the effects of peatland development on streamflow. The Peatland Hydrologic Impact Model is largely physically based...
Landslide Hazard Rating for the Oregon Coast Range
The landslide hazard rating system for shallow soils on steep terrain over hard sandstone has three components: ground water response to precipitation, soil shear strength (including root...
Synthetic Unit Hydrographs for Ozark Watersheds
Few concepts in modern hydrology have been more widely used and abused than unit hydrograph theory. Nevertheless, during the years since its introduction in 1932 as an extension of the...
Predicting Forest Snow Water Equivalent
In California, the snowpack of the Sierra Nevada provides more than one-third of the state's water needs. Regression models used to forecast this supply do not include measurement...
Soil Movement and Surface Roughness on Wyoming Rangelands
Soil movement and surface roughness parameters were evaluated as a function of response to livestock grazing and semiarid shrub control treatments. Repeated elevation measurements of erosion...
Erosion, Productivity and Rangeland Watershed Planning
The Bureau of Land Management is responsible for the management of over 160 million acres of rangeland in the western United States. The principal uses of these rangelands are the grazing...
A Methodology of Assessing Nonpoint Source Pollution from Agricultural Watersheds
Appraisals of water quality impacts induced by applying watershed management practices are difficult due to many factors. Lack of existing research data base, the diffusive characteristics...
