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...

Design of Shoreline Protection Measures : The Importance of Geotechnical Engineering in Waterfront Design
Over the past decade, there�s been an increased realization of the need to better protect our shorelines, particularly in urban environments along coastlines that have already been impacted by storm surge...

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...

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...

Grid Pavement
Open grid pavements consist of concrete or plastic units with large surface openings filled with a permeable joint material, typically small aggregate (ASTM No. 8 or No. 89), sand, or...

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...

Estimation of Consolidation Properties of Clay from Field Observations
Analyses to obtain theoretical time-settlement curves for embankments typically make use of soil properties measured in the laboratory on small disturbed samples subject to strain rates...

Measurement of Hydraulic Conductivity of Partially Saturated Soils
Increased interest in protection of the environment has led to a need to be able to predict long-term movement of moisture, and contaminants, in the vicinity of shallow land disposal sites...

Grouting Methods
This chapter discusses common grouting methods used in underground applications in both soil and rock. Jet, compaction, permeation, and hydrofracture grouting methods are frequently used...

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...

Viral Fate and Transport Modeling under Salinity Impact
This research studied the impact of salinity on sorption and transport of MS-2 in saturated sand through one-dimensional column experiments. MS-2 was used as a surrogate to understand...

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...
