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...
DSS: A Dam Site Selector Expert System
The Dam Site Selector (DSS) expert system is an aid for rating an area for use as a dam site and reservoir. It was developed for use in a graduate level hydrology design course at Purdue...
Recognizing Liquefaction Hazard
Technique for assessing liquefaction hazard are considered herein: Methods for compiling regional opportunity maps are reviewed and a crude national map is developed. Compilation of regional...
Jet Grouting: The Pace Quickens
Over the past year, use of jet grouting in the U.S. has nearly quadrupled. A versatile tool, it has performed well in settings as diverse as a railway tunnel, industrial waste site and...
Evaluating Potential Artificial Recharge Projects
The success of an artificial recharge project can be directly tied to the quality of planning of the potential projects and/or sites. The paper's purpose is to identify the...
Breakwater Breakthrough�Bold New Breakwaters
A new rubble-mound breakwater design is a departure from the conventional approach detailed in the U.S. Army Corps of Engineers Shore Protection Manual. The new concept, called the berm...
Effects of the 1985 Earthquake in Lazaro Cardenas, Mich.
An account is presented of a geotechnical survey made shortly after the major earthquake of September 19, 1985 (magnitude 8. 1) at the industrial port of Lazaro Cardenas in the state of...
Monitoring for Hazardous Waste Leaks
It is safer and cheaper to keep hazardous wastes out of the groundwater and the ground than to remove them. But better monitoring will be required. In this three-part article, the first...
Courting Public Opinion
Promoting good community relations is an integral part of hazardous waste projects. Before field investigations are conducted, neighboring communities should be advised of the proposed...
A Watery Grave
Subseabed disposal may be the most acceptable means of dealing with radioactive wastes. Land disposal sites are difficult to find and politically difficult to use. Little research has...
Probabilistic Site Strategy for Transmission Lines
A probability-based geotechnical site characterization strategy is presented for transmission line structures. Because site-specific data are sparse for these structures, a Bayesian model...
Construction and Design of Foundations for French Overhead Power Transmission Network
This paper summarizes present conception and design of foundations for 90 to 400 kV overhead lines in France. Firstly principles of geotechnical studies in use are presented: various types...
Investigation of Excavatability in the Piedmont
The lateral and vertical variability of rock weathering in the Piedmont presents significant problems in evaluating the probable cost of excavation for deep basements, pipeline, road cuts,...
Dispersive Soil and its Influence on the Design of Reach 1A of the Tucson Aqueduct?Central Arizona Project
An extensive geotechnical field exploration and laboratory testing program was conducted because of dispersive and erosive soils along the alignment of the canal. The canal design was...
Survey of Groundwater Contamination in Massachusetts
Public water supplies in Massachusetts have been contaminated or threatened from a number of sources. The purpose of this paper is to outline the nature of groundwater contamination and...
A Call for New Directions in Drilling and Sampling Monitoring Wells
