Airport on the Move
The Dallas/Fort Worth International Airport (DFW) is building an automated people mover (APM) system as part of a five-year, $2.6-billion capital development program that includes three...

Going Against the Grain
Conventional wisdom has it that granular soils perform better in mechanically stabilized earth (MSE) wall systems. Their properties are well known and simple to express in mathematical...

September Eleventh, The Days After, The Days Ahead
Civil engineers assumed prominent roles in the aftermath of the terrorist attacks on the World Trade Center and the Pentagon and are leading the efforts to evaluate not only the performance...

Good Vibrations
As advances in material technology and structural efficiency find reflection in structures that are lighter, more slender, and more daring architecturally, design teams must focus more...

Raising the Bar of BART
Although it was originally designed to withstand a strong earthquake, and did so admirably in 1989, the Bay Area Transit (BART) system was recently evaluated to determine its ability to...

Integration of Watershed and Ecological Site Land Classification Scales Using GIS Technology
Advanced analysis of hydrologic processes for use in natural resource simulation models and related applications including rangeland health assessments can be facilitated by the integration...

Watersheds: Preparing Students for the Future
Colorado State University continues to maintain the only undergraduate major in Watershed Science since its inception over four decades ago. As the flagship of Watershed Science, CSU has...

The Watershed Modeling System
The Watershed Modeling System (WMS) is a comprehensive environment for hydrologic analysis developed by the Environmental Modeling Research Laboratory (EMRL) at Brigham Young University...

Stochastic Simulation of the Colorado River Flows Using SAMS
The main purpose of this presentation is to illustrate the applicability of SAMS to the Colorado River system. For this purpose we have utilized monthly data at 29 sites in the basin....

Probabilistic Simplified and Detailed Subsurface Drainage Water Quality Modeling of Nitrate Leaching
A transparent uncertainty structure is derived for simplified and detailed conceptual nitrate leaching as a result of a probabilistic modelling procedure. The uncertainty structure consists...

Predicting Droughts for the South Platte River System
In this paper we apply probability theory and stochastic processes to determine drought properties, particularly drought duration. Spccilicslly, we model the sequences of wet and dry years...

Hydrogeology and Irrigated Agriculture
A review of drainage problems and groundwater processes on the west side of the San Joaquin Valley (SJV), California, provides useful perspectives on hydrogeology and irrigated agriculture....

Spatial Decision Support System for River Basin Management
MODSIM is a generalized river basin network flow model designed to simultaneously assure that water resources are allocated according to physical, hydrogeological, and institutional/administrative...
