Your Numerical Model Begins at the Site Investigation � Phase Improving the Suitability of Numerical Geotechnical Modeling
The success of an advanced geotechnical numerical analysis depends foremost on a thorough geologic and geotechnical understanding of the site, and thus the geometric definition and adequacy of input parameters...
Intelligent Geo-Construction Drilling Equipment: Delivering More Than Meets the Eye
The complexity, risk, and demands of engineered geo-structural projects have increased, seemingly exponentially, through the years. Physical and capital resources to deliver such projects, however, have...
Spin, Spin, Spin
A scalable, vertical axis windmill tower with dynamic shutters that decrease wind loading on the structure has won an energy efficiency design contest....
Delegate, Network, and Ask for What You Want
Justin Siegrist, P.E., M.ASCE, is the hydraulic modeling lead in the Cincinnati office of Wade Trim. His advice to young engineers: delegate, network, and ask for what you want....
Calibration of Jackup Leg Foundation Model Using Full-Scale Structural Measurements
The fitness of jack-up rigs to operate in varying water depths and weather conditions is determined by "site-specific" structural assessments. These assessments are conducted by a wide range of companies...
A Preliminary Case for the Existence of Hurricane Alleys in the Gulf of Mexico
A review of hurricance intensity in the Gulf of Mexico suggests there are two alleys where hurricanes are roughly 20% more intense than elsewhere. This paper develops a physical basis for the alleys using...
Heave Compensated Landing System - A Novel Tool for Subsea Intervention
This paper presents a new intervention system that allows the use of a low cost workboat to deploy and recover delicate payloads in subsea installations. Vessel motions are decoupled from the subsea package...
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...
Hydrologic and Hydraulic Design Methods
Computational methods for hydrologic analysis, hydraulic functions, and treatment capacity of permeable pavements vary depending on the complexity of the design and level of detail in...
Geo-Congress 2014
Technical Papers and Keynote Lectures
Proceedings of the 2014 Geo-Congress, held in Atlanta, Georgia, February 23-26, 2014. Sponsored by the Geo-Institute of ASCE. GSP 234, Geo-Congress...
Pile-Driving Formulas for Friction Piles in Sand
Dynamic pile-driving formulas are widely used in predicting the load-carrying capacity of friction piles and in writing pile-driving specifications. Further, when load tests are available,...
Design and Installation of Auger Steel Catenary Risers
The Auger export pipelines are connected to the TLP by steel catenary risers (SCRs). This is believed to be the first time steel pipe has been used for catenary risers. SCRs offer advantages...

Proceedings of the Geo-Shanghai 2014 International Conference, held in Shanghai, China, May 26-28, 2014. Sponsored by the Geo-Institute of ASCE. These...
Adapt to Dynamic Conditions and Practice
This chapter discusses the fourth guiding principle for critical infrastructure: adapt critical infrastructure in response to dynamic conditions and practice....
Groundwater Flow Model Development at the Nevada Test Site
The Underground Test Area Project (UGTA) of the National Nuclear Security Administration.s Nevada Site Office is in the process of assessing and developing regulatory decision options...
Maximum Weighted Log-Likelihood Estimation for Parameterization Selection Uncertainty
Hydraulic conductivity identification remains a challenging inverse problem in groundwater modeling because of inherent non-uniqueness and lack of flexibility in parameterization methods....
Evaluation of a Bias Aware Ensemble Kalman Filter Using a Scaled Aquifer Transport Experiment
In this study, a bias-aware Ensemble Kalman Filter (EnKF) is applied to a scaled aquifer transport experiment (1-cm of the model equals 1-m at field scale and 1-day of model transport...
Groundwater Transport Modeling Using Fuzzy Sets and Fuzzy Logic
Modeling of groundwater flow and transport is inherently uncertain. The predictive capability of the model depends upon both the quantity and quality of hydrogeologic data. The introduction...
Evaluation of IA SWAT Testing Protocol for ET Controllers
In recent years the Irrigation Association (IA) has developed a testing protocol for Smart Water Application Technologies (SWAT). These technologies consist of irrigation controllers such...
