Subsurface Utility Engineering and Megaprojects: Avoiding Underground Conflicts Helps Speed Project Delivery
Experienced project owners realize that utility conflicts can be risky and pose unexpected impacts on the cost and delivery of projects, especially in urban settings. To help overcome these impacts, Subsurface...

Trenchless Goes Hybrid: Old Tricks Are Finding New Applications
The International Society for Trenchless Technology defines trenchless technology as "Underground construction methods of utility installation, rehabilitation, inspection, location and leak detection,...

Beyond the Water’s Edge: Geotechnics in the Wet
Gaining insight into the subsurface and developing an understanding of what’s hidden below ground is a key to the design and construction process. Geotechnical engineers and geologists often develop their...

Poison Oak, Mistakes, and Lessons
When things go wrong in geotechnicalengineering — like ground movements andearthwork construction delays — failureinvestigations are often performed. In a typical geotechnical project, the path is relatively...

Finite Difference Analyses for Sand Drain Problems
The geotechnical literature contains a number of papers in which sand drain installations are described and field performance is compared with theoretical predictions. Some of the field...

Design-Build and Public-Private Partnerships: Risk Allocation of Subsurface Conditions
Project Owners, especially in the public sector, are exploring and utilizing alternative project delivery methods, such as design-build (D-B) and public-private partnerships (P3s). Some...

Prefabricated Vertical Drains — The Squeeze is On

Transport Model Uncertainty and Sensitivity Analysis for Groundwater Releases of Radionuclides from Subsurface Nuclear Tests
Uncertainty analysis of groundwater flow and transport models is a topic of considerable interest in the groundwater modeling communities. The Underground Test Area (UGTA) Project of the...

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...

Considerations Regarding Geochemical Transformations Downstream of Subsurface Wastewater Effluent Disposal Facilities
Many suburban and rural communities use subsurface disposal in conjunction with on-site and other small decentralized systems. In addition, to reduce the impacts of wastewater treatment...

Watershed Modeling for Surface-Groundwater Interaction
Groundwater use has increased rapidly due to irrigation development in the Great Plains. This is especially true in the Republican Basin that intersects the three states of Nebraska, Kansas...

Beans Help Build Deep Drainage Trenches

Pile-Head Behavior of Rigidly Capped Pile Group

Application of TOPNET in the Distributed Model Intercomparison Project (DMIP)
This paper describes the application of a networked version of TOPMODEL, TOPNET, as part of the Distributed Model Intercomparison Project, DMIP. The model implementation is based on a...

Water Quality Aspects of Irrigation and Drainage: Past History and Future Challenges for Civil Engineers
This paper presents a brief history of irrigation and drainage related to ASCE activities on its Jubilee. This paper discussed legislation and policies that affect irrigation and drainage...

Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data
Development of the referenced Standard began in 1996. It is slated for publication in summer of 2002. The intent of this standard guideline is to present a system of classifying the quality...

Non-Destructive Excavating Around Pipelines and Challenging Conditions
Hydrovac technology provides engineers and contractors with a unique solution for non-destructive excavating around sensitive buried lines. As a non-mechanical excavating method, it is...
