Computer-Aided Studies of Complex Soil Moduli
Low-cost microcomputers and new electronic components make it possible to measure accurately the phase and amplitude of mechanical waves in the frequency domain at a small fraction of...

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....

Snow Effects on Pile Design Temperatures
The construction of North Slope aboveground pipelines and gathering lines is generally from snow workpads constructed proximate to existing access roadways. The pile support centerline...

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...

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...

A Look to the Future in Watershed Management
The discipline of watershed management will continue as a viable specialized field as the scarcity, demand, and price of water increase in the future. Training of watershed managers should...

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...

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...

Santa Barbara Hydrograph with Green-Ampt Infiltration
Numerous models are available to estimate rainfall-induced runoff from watersheds. The leading criteria in model selection is often reproducibility. Models that are reproducible are often...

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...

Urban Hydrology for Small Watersheds (Revised 1985)
Urban Hydrology for Small Watersheds, Technical Release 55, was first issued by the Soil Conservation Service in January 1975. It is a guide for SCS field personnel for estimating hydraulic...

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...

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...

Assessing Risks of Impaired Hydrologic Function
This paper describes the rationale and use of a 'resource tolerance' to evaluate hydrologic function and presents a method to establish a relative tolerance threshold...

The Role of Multiple Level Hydrologic Analysis in Watershed Management?A Case Study in Trinidad
An accurate estimation of peak flood flows and its correlation with existing and future land use are basic requirements for the scientific management of Watersheds. An accurate estimation...

Streamflow Generation from Subalpine Forests
Much of the hydrologic modelling done in the subalpine forest of the central Rockies is based on the Subalpine Water Balance Model. This paper reports on plot studies on the Fraser Experimental...

Snow Management at Ski Areas: Hydrologic Effects
Several types of snow management are practiced at downhill ski areas. Each of these activities has a variety of hydrologic consequences. The extent to which these management practices...

Interrelating Infiltration Measurements
Field measurements of infiltration rates are frequently used to index environmental conditions, soil hydrology, and the potential for rainstorm response. However, the variety of methods...
