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...
Review of Climate Science for Engineering Practice
Weather and climate are a factor in civil engineering design and practice. Weather is defined as the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure,...
Non-Destructive Strength Evaluation of a Continuous, Reinforced Concrete Slab Bridge
In the state of New Mexico, a significant number of reinforced concrete slab (RCS) bridges provide service on interstate highways I-10, I-25, and I-40 that are subjected to large amounts...
Marginal Permafrost a Foundation Material in Transition
At the edges of the world's cold regions lie areas of marginal permafrost. It is a changing landscape that seems to be growing in extent, yet it retains chameleon-like qualities...
Refrigerated Foundations
Refrigeration systems used to cool foundations on frozen ground can be classified as either active or passive, depending on whether external energy is used to power the systems. If pumps,...
Outdoor Human Comfort and Its Assessment
Prepared by the Task Committee on Outdoor Human Comfort of the Aerodynamics Committee of ASCE. This report describes state-of-the-art methods for assessing...
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...
Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...
Effect of Aluminum Compression on ACSR Conductor Sags at High Operating Temperatures
Deregulation and restructuring are sweeping the electric utility industry in the United States. As a result, many utility engineers are analyzing, re-rating, and upgrading their most critical...
High Performance Dampers for Bridges
A multi-disciplinary research study investigates the use of shape memory alloys as seismic dampers in bridges. Shape memory alloys are a class of alloys that display several unique characteristics,...
Monitoring the Fresh Kills Landfill (Available in the Geoenvironmental Special Section only)
A unique system has been developed to assess the stability of the Fresh Kills Landfill, in New York City, using more than 260 geotechnical instruments and automatic processes. The system...
Design Live Loads for Parking Garages
The objective of this research project is to obtain a better understanding of parking garage live loads and to recommend an appropriate value for design. A load survey was conducted in...
The SPRP Project: An Overview
The National Science Foundation's Office of Polar Programs (OPP), the lead agency for the U.S. Antarctic Program, has begun construction of a replacement station for the Amundsen-Scott...
Holding Court
Contractors had their work cut out for them when structural engineers specified concrete-filled steel tubes for the Thomas F. Eagleton Federal Courthouse's perimeter columns....
Order Amid Uncertainty (Available in Geoenvironmental special issue only)
Bayesian statistical methods allow engineers to deduce probabilities from incomplete information. If there is a theoretical or empirical reason why a particular probability distribution...
Basin Response Time: Potential Hydrologic Basin Handprint
Hydrologic lead time is an important factor in many water resources engineering applications. The determination of the response time of a watershed to runoff-producing rainfall is the...
Fuzzy Rule-Based Forecasting of Extreme Rainfall Probability Conditioned on Sea Surface Temperature
(No paper) The recent El Nino event demonstrated the importance of sea-surface temperature on rainfall anomalies. The purpose of this paper is to develop a methodology to forecast extreme...
Comparison of Complete Modeling/Simplified Modeling of Zaragoza City Water Supply Network
(No paper) Zaragoza is a Spanish city with 600.000 inhabitants and a water supply network of 900km long. The Council technical services uses a Microstation based GIS, GRED, for network...
Securing the Stone
To prevent spalling at edges on thin stone veneer, engineers who design stone cladding pay special attention to the connection details. Kerf clips, 100-150 mm long, that distribute load...
Casting Hot and Cold
Contractors and engineers battled the Minnesota winter to build a concrete segmental bridge with form travelers. Superstructure segments were poured in temperatures as low as -19F, using...
