The Design of Hail Suppression Operations
When hail suppression operations are being considered, it is already understood that hail damage is a significant problem in an area in which the political subdivision, organization, or...

Conduct of Operational Hail Suppression Projects
Those conducting hail suppression operations should be vigilant and always prepared to react when potential hailstorms begin to develop. In this chapter, some guidance is provided for...

Evaluation of Hail Suppression Efforts
The rationale for conducting project evaluations is to find out how successful the operations are in achieving the desired results. This assessment is more easily said than done. It is...

Applying Scanning Technology to Tunnel Inspections: Leveraging Technology to Reduce the Public Agita
A large number of transit and vehicular tunnels in the New York Metropolitan area were inundated by the tidal surge caused by Super Storm Sandy on October 29, 2012. The storm created major...

Landslide Risk Perception: Consequences of Failure to Reconcile Contradictory Beliefs
While the basis for geotechnical safety is important, public perceptions of risk and its apparent willingness to ignore or discount hazard warnings should also be considered. Why does...

Small Projects are Big Deals
Geotechnical engineers work on a wide array of projects, ranging from small retaining walls or pavement projects, to construction of dams, canals, and foundations for bridges and high-rise...

The Leaning Towers of Wilmington, Delaware: Emergency Response and Retrofit of the I-495 Viaduct to Address Lateral Squeeze
On a sunny, summer afternoon last June, the project manager for AECOM's open-end bridge design contract with the Delaware Department of Transportation (DelDOT) received an...

Geotechnical Risk Management: The Five Non-Technical Topics that are Crucial for the Successful Practice of Geotechnical Engineering
It is fair to state that the aspects of civil design and construction referred to as geotechnical engineering can be characterized as inherently risky. Geologic processes are complex,...

GeoTechTools – Your Ground Modification Website: Solutions for Improved Decision Making and Risk Mitigation
An immense web-based toolbox for the engineering and construction of earthworks is now available at GeoTechTools.org. This exciting collection...

A Light in the Deep: The Future of Offshore Site Investigations
For deep-water energy developments, hazard identification and risk assessments (that is, assessing the probability of occurrence along with the consequences of failure) are more important...

Making Big Data Work for You and Your Project: A 3-D Geotechnical Model is a Smart Way to Work
Modeling the stratigraphy beneath a site and assigning soil and rock properties are important steps in geotechnical engineering. Geotechnical engineers often need to model ground conditions...

BIM in Geotechnics: The Benefits of Including Geotechnical Data in Building Information Modelling
Building Information Modelling (BIM) is becoming increasingly common around the world on building and civil engineering projects, but what are the benefits to geotechnical engineers and...

Becoming Greener with Green Sand: An Iron Castings Company Devises an Environmentally Friendly Liner System Reusing Foundry Byproduct
Metalcasting is one of the oldest methods of recycling—humans have a few millennia worth of experience with the technique—but today's industry still battles public preconceptions...

Introduction
The purpose of this white paper is to: foster understanding and transparency of analytical methods necessary to update and describe climate, including possible changes in the frequency...

Failure of a Twenty-Foot High Retaining Wall
A cantilever retaining wall, designed in apparent accord with provisions in a civil engineering handbook, failed soon after construction. Analyses of the causes of the failure are presented....

Effective Stress Theory of Soil Compaction
The shape of the moisture-density curve obtained from compaction tests has been explained in terms of capillarity and lubrication, viscous water, and physico-chemical interactions. None...

Application of Model Pile Tests to Axial Pile Design
Experiments conducted with instrumented model pile segment probes at Harvey and Empire, Louisiana are summarized and the observed behavior interpreted. Correlations are developed for the...

Sustainable Development — A Geotechnical Perspective
Sustainability has become a key factor in major construction projects these days, and many geotechnical engineers have started focusing on the concept. Owners, public agencies, and the...

Managing Geotechnical Assets to Improve Highway System Performance
As geoprofessionals, we have a great opportunity to look at our work in new ways and to show its value to others. Highway agencies are looking to get the most from their assets and with...

Condition Indices, Performance Measures, and Managing Performance Data for Geotechnical Asset Management – Don't Get Buried!
Why don't transportation agency assets like pavements, bridges, and earthwork have a Check Engine light? Why can't you simply pull up the complete history and life cycle plan for them?...
