Working Platforms for Specialty Geo-Construction
A major cause of rigs toppling over is the state of the "working platform" that they must work from. A working platform is a layer of material, often compacted sand or gravel, placed over the subgrade,...
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....
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...
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...
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...
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....
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...
Effects of Impervious Area Estimation Methods on Simulated Peak Discharges
The variability of simulated flood discharges is evaluated using two methods for estimating impervious surfaces and common design methods in the Mission Creek watershed (31 sq km) located...
Geo-Denver 2007
New Peaks in Geotechnics
Proceedings of Geo-Denver 2007, New Peaks in Geotechnics, held in Denver, Colorado, February 18-21, 2007. Sponsored by the Geo-Institute of ASCE. This collection contains nearly 300 papers...
Contributing Factors
This chapter examines contributing factors of the hurricane protection system failures, including the underappreciated risk to New Orleans, a piecemeal implementation of the hurricane...
Stochastic Analysis of the Truckee River Flow System
The Truckee River system is a complex system that involves a number of hydraulic structures such as natural and artificial lakes and reservoirs and diversions. Streamflow data have been...
Firepower
The processes put in place by water utilities are designed with the quality of water normally received for treatment in mind. But the runoff from areas ravaged by fire can degrade that...
Water Treatment Plant Design
Let a team of water treatment plant design experts . with contributions from more than 30 international authorities -- give you comprehensive guidance on modernizing existing water treatment...
Long-Term Groundwater Monitoring
The State of the Art
Prepared by the Task Committee on the State of the Art in Long-Term Groundwater Monitoring Design of the Environmental and Water Resources Institute of ASCE. ...
Perspectives in Civil Engineering
Commemorating the 150th Anniversary of the American Society of Civil Engineers
This report contains 27 papers that serve as a testament to the state-of-the-art of civil engineering at the outset of the 21st century, as well as to commemorate the ASCE's...
