CPT Indexing of In Situ OCR in Clays
Cone penetration tests may be used to index the in situ preconsolidation pressure in clay deposits. A specified relationship between C//u/ sigma //vo and the overconsolidation ratio (OCR)...
A Study of the Potential for Groundwater Contamination by Alcohol Blended Gasolines
This paper describes the increased solubility of gasoline-hydrocarbons in groundwater when alcohols are used as octane enhancement additives and the effects of 'gasohol versus...
Relative Landslide Susceptibility in Davis County, Utah?A Multivariate Approach
The complex distribution of soil properties makes prediction of slope stability extremely difficult in these mountain watersheds. The need to assess these watersheds for their susceptibility...
Conjunctive Use and Managed Groundwater Recharge: Engineering and Politics in Arid Lands
In regions with alluvial groundwater basins, increasing consumer demands for water, irregular surface water flows, and high evapotranspiration rates, managed recharge and long-term conjunctive...
Modeling an Alluvial Aquifer with Flood Irrigation
Interaction between an unconfined alluvial aquifer, recharged by flood irrigation, and the associated stream system in a glacial outwash area of Wyoming was studied. The United States...
Making Water System Rehabilitation Decisions
Making decisions regarding water distribution systems has always involved a great deal of judgment due to the complexity of the decisions involved. This paper presents a framework for...
An Experimental Study on the Effect of Wastewater Application in Dry Wells and Its Impact on Groundwater
A study was conducted in order to gather accurate information on the effectiveness of dry wells for use in wastewater disposal and the effect of such disposal practice on groundwater....
Model for Optimal-Risk Based Water Distribution Network Design
Various models using a variety of optimization techniques were developed for determining pipe diameters, network layout, pump capacities, and other design parameters. The objective function...
Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....
Grand Canyon Water Line by Directional Drilling
The South Rim Village at Grand Canyon National Park obtains its water supply from a point called Roaring Springs which is located approximately 15 miles across the Canyon on the North...
The Past, Present & Future of Earthmoving Scrapers
This paper is a summary of the history and development and use of earthmoving scrapers. It will also take a look at the future of this type of machine. We'll build the discussion...
Use of In Situ Tests in Geotechnical Engineering
In the past ten years, many new types of in situ test equipment and many new techniques have been developed. The papers in this volume are concerned with applications of in situ measurement...
Ice Forces on Bridge Piers
The force that river ice exerts on bridge piers has been studied in the field and with models in the laboratory. Ice forces are a function of the strength, thickness, failure mode and...
Continuous Loading Consolidation Testing Using a Microcomputer for Control and Data Acquisition
An overview of some of the methods of one-dimensional consolidation testing currently in use is presented, including the load-increment test, the constant rate of strain test, the constant...
Designing for Flow
Geotextiles used for in-plane drainage can carry surprisingly large amounts of water within their structures. These composite drains, known as sheet drains, prefabricated drainage composites...
Porewater Pressure in Clays Below Caisson Islands
Unfrozen lightly overconsolidated clays are a significant factor in the design and performance of exploration caisson retained islands in the Canadian Beaufort Sea. At two sites (Tarsiut...
Electrical Resistivity Techniques for Offshore Arctic Geotechnical Engineering Applications
The electrical resistivity of an arctic marine soil depends on the porosity, pore water salinity, grain size and shape, clay content, and degree of ice-bonding of the soil. Therefore,...
Soil Strength Determinations from the Cone Penetrometer Test
Geotechnical exploration in offshore Arctic regions often relies upon the electric Cone Penetrometer Test (CPT) because of its speed, economy, data continuity, and general reliability....
Arctic Penetration Test Systems
Geotechnical exploration in offshore arctic regions relies upon the electric Cone Penetrometer Test (CPT) because of its speed, economy, data continuity, and general reliability. By adding...
Analysis of a Production Well Through Sediments Containing Gas Hydrates
In some of the petroleum reservoirs recently discovered north of the Arctic Circle, production wells extend through thick permafrost. Several authors have reported zones of gas hydrate...
