Airport Terminal Design Challenges
In February 1989, the Metropolitan Washington Airports Authority began the process of designing and constructing a new terminal at Washington National Airport to address the needs of its...
Dulles International Airport Construction Challenges
The expansion of the Main Terminal at Dulles International Airport was anticipated and planned for during the original construction of the building in 1962. The most difficult portions...
Utilization of Phosphogypsum-Based Slag Aggregate in Portland Cement and Asphaltic Concrete Mixtures
This study centers around the potential utilization of phosphogypsum-based slag aggregate as a substitute for coarse aggregate in both portland cement and asphaltic concrete surfaces for...
Nighttime Cement Concrete Pavement Replacement Seattle-Tacoma International Airport
Several airfield improvement projects are currently underway at Seattle-Tacoma International Airport (Sea-Tac), many of which are being constructed using cement concrete pavement. Due...
Cost Considerations in Planning Pier Terminals
The deregulation of the air transport economy is gradually leading to the involvement of private developers in airport terminal financing. Even the airports run by government agencies...
Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....
Aquifer Storage and Recovery in the Floridan Aquifer System of South Florida
This paper describes the feasibility, construction, testing, and storage zone development of the Boynton Beach Aquifer Storage and Recovery (ASR) well, the first successful ASR project...
Problems Faced by Faculty in Minority Institutions
The primary objective of this paper is to list some problems faced by faculty engaged in both research and instruction in Minority Institutions (MIs) and to suggest solutions to them....
Willingness and Ability to Pay for Rural Water
Estimates of willingness to pay for rural water systems were developed in South Dakota, Oklahoma, and Montana from responses to contingent valuation surveys. Ability to pay was also estimated...
Evaluating Sensitivity of Hydraulic Control Optimization Models
Sensitivity of hydraulic control optimization models to variation in gradient constraints is examined. Monte Carlo simulation is used in conjunction with repeated optimization runs to...
Probabilistic Characterization of Droughts
The Palmer Drought Severity Index (PDSI) uses a set of meteorologic and hydrologic variables to create a numerical value for drought severity. The index values are grouped into drought...
Water 2050-Supply for the Portland, Oregon Metropolitan Region Using the Integrated Resource Planning Process
This paper presents information about the long range regional water supply planning work that is being conducted in the Portland, Oregon metropolitan region. An integrated resources planning...
Application of the PCRSS Reservoir Simulation Model to the Salt River Project
PCRSS is a general purpose reservoir system model construction kit. It allows the user to specify the system configuration and parameters through the use of a windows based graphic user...
A Decision Support System for Multi-Purpose Reservoir Operations
A generalized decision support system (DSS) is presented for developing optimal operation policies for multi-purpose reservoirs. The model is designed for single reservoirs, although is...
Design Considerations for Night Storage in Irrigation Systems
Due to the farmer social and economical changes, irrigation during night became rare. Most of the night discharges flow to drains. A design procedure has been developed for storage in...
Modeling Flow in Variably-Saturated Porous Media
An expression for effective hydraulic conductivity to solve groundwater flow problems is developed. Also, a refined Monte Carlo (MC) simulation procedure is proposed. The developed methodologies...
Partnering in Environmental Restoration: The Coastal America Model
The Coastal America Partnership was initiated in 1993 with the underlying principal that collaborative efforts would be more successful than attempting individual agency solutions. To...
Grazing for Funding: Agency Hydrodiplomacy
Community leaders may be unaware of monies and expertize available to solve water-related problems. To remedy this situation, staff of the Mobile District of the U.S. Army Corps of Engineers...
Multiobjective Models for Determining Freshwater Inflows to Bays and Estuaries
This paper presents four multiobjective models for the estuary management problem, including goal programming, the epsilon constraint method, the surrogate worth tradeoff method and the...
Alternative Designs for a Water Resources Planning and Management Electronic Information Exchange Network
The proliferation of electronic bulletin boards, fax and other electronic media encourages the use of alternative information sharing and retrieval methods as a routine part of business...
