Standards for Pile Load Tests in Permafrost
A requirement exists to establish standard procedures for conducting pile load tests in permanently frozen soils. The methods outlined in the ASTM Standards for piles in thawed soils do...
Attenuating Creep of Piles in Frozen Soils
Results of several long-term creep tests of piles in frozen soils are analyzed; the primary or attenuating creep is predominant in most cases. For effective design of pile foundations...
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....
Installation of Category I Caissons
Founding a proposed safety-related Category I structure of a nuclear power plant on rock socketed caissons necessitated using precision installation techniques. These techniques were chosen...
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...
Behavior of Drilled Piers in Layered Soils on Texas Barrier Islands
Twenty-eight full scale load tests and the results of 41 geotechnical studies were analyzed to correlate shear strength interpreted from field and laboratory test data with those derived...
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...
Observations on Load Tests for Drilled Shafts
This paper focuses on three specific areas pertaining to load tests for drilled shafts: 1) basic considerations and load testing procedures, 2) interpretation of uplift load test information,...
Watershed Management in 1985
Today's technology in subalpine watershed management is based on carefully designed watershed experiments beginning with Wagon Wheel Gap in 1909. Subsequent advances in process...
International and Educational Aspects of Watershed Management
International donor agencies involved in furnishing technical and economic assistance for increasing food and fiber production are focusing their attention towards rain-fed agricultural...
Cover Allocation in Rangeland Watershed Management (A Review)
The importance of cover on rangelands has been recognized for many years. This paper reviews the importance of cover in terms of infiltration and erosion and provides management recommendations...
South Branch Rockaway Storm Water Management Study
The Division of Water Resources of the New Jersey Department of Environmental Protection, the Hunterdon Soil Conservation District, the United States Department of Agriculture's...
Crown Corporation Approach to Watershed Management
On July 1, 1984, the Government of Saskatchewan proclaimed the Water Corporation Act. The Act formed the legislative basis for the newly formed Saskatchewan Water Corporation and ushered...
Modelling Transpiration of Subalpine Trees in the Central Rocky Mountains
Forest evapotranspiration (ET) has long been recognized to be a major component in the mass water balance of subalpine watersheds in the central Rocky Mountains. In recent years, research...
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...
The Improved SCS TR-20 Network Watershed Model
SCS Technical Release 20, 'Computer Program for Project Formulation - Hydrology' (TR-20), has been revised. Major revisions include new procedures for hydrograph...
Evaluation of Runoff Prediction Using Synthetic Rainfall and CREAMS
Of all the climatological data, rainfall is the variable to which a watershed responds most significantly. The amount and sequence of occurrence of rainfall are most important in the prediction...
