Runoff Forecasting Using a Local Approximation Method
Forecasting of hydrological events, particularly floods, is an important topic of concern for hydrologists. Flood hazards can be prevented or their effects minimized if prior warning of...

SAMS: Software for Simulating Streamflow Series
This paper introduces SAMS, a computer software developed for the analysis, modeling, and generation of hydrologic time series such as annual and monthly streamfiows. It is written in...

An Engineering Information System Application for Water Supply and Distribution Systems
Engineering information systems are characterized by both static infrastructure and dynamic time dependent data. Telemetered readings can often be relatively substantial over an extended...

Measuring and Modeling Time Dependent Soil Behavior
This proceedings presents a series of papers on both laboratory and field investigations, as well as constitutive modeling efforts, that all deal with the time dependence of soils and...

Potential demand for passenger travel to orbit
In recent years the possibility of `space tourism', that is individual passenger travel to space on a commercial basis, has received increasing attention. The possibility of such an activity...

Inter-stellar Propulsion: The Need for Speed
Interstellar travel is certainly one of mankind's next step to reach for the stars. Four ideas for interstellar propulsion are discussed in this paper: the Orion Project, Deep Space Ramjets,...

Behavior of RC Beams under Sustained Load
Experimental results of eight reinforced concrete beams under 3-month's sustained load, with the ratio of shear span to depth equal to 2.5, are reported. It is shown by tests that the...

Time-Dependent Load-Distribution Behavior of Parallel-Member Wood Systems
The effect of differential member creep on the load-distribution behavior of parallel-member wood systems is examined. Variability in the creep response of the individual component members...

Observations Related to the Use of the Sigma Coordinate Transformation for Estuarine and Coastal Modeling Studies
One of the common techniques used in application of time-dependent, three-dimensional models addressing estuarine and coastal environmental problems is the sigma coordinate transformation....

A Method for Locating Spikes in a Measured Time Series
Raw directional wave sample time series are frequently contaminated with spikes from various sources. The standard procedure in correctly editing these time series includes locating and...

Evolutionary Fourier Analysis of Wave Data
A new method is presented for analyzing nonstationary water level height time series. The usual assumption of pseudo-stationary intervals is avoided and the wave spectra can be changing...

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...

California Airports: Ground Access Vehicle Trips, Emissions and Emission Reduction Strategies
The following paper discusses the volume of trips and emissions associated with ground access vehicles to an d from California airports, and potential ways to reduce these emissions. this...

Switzerland: Rail Access to Airports and the Fly-Luggage System
Swissair and the Swiss Federal Railways (SBB) offer a unique service for air passengers travelling to and from their Swiss airport of departure or arrival. In conjunction with private...

Demand/Supply Relationship in Transportation Network Design Problems: A Genetic Algorithm Approach
The cumulative genetic algorithm (CGA) has its significant advantages over the heuristic algorithms in dealing with transportation network design problems. Using CGA, the entire solution...

Electronic Yellow Pages for Pre-trip Planning Systems
An attempt has been made to introduce Electronic pages or Electronic yellow pages which work similarly to Yellow Pages. The overall system is divided into user interface, network building,...

Coastal Eutrophication and Temperature Variation
A 3-D hydroecological model has been developed to simulate the impact of climate-change-induced daily temperature variation on coastal water quality and eutrophication. Historical daily...

Long Term Predictability of River Stages under ENSO Influence
The paper explores the bases for alternative approaches to river flow and hydrologic time series forecasting. The precipitation that forces river flow contains significant modes of variability...

Validation and Application of THE Model's Trip Table Estimation Process
The Highway Emulator (THE) Model is a microcomputer based travel demand forecasting program maintained by the Central Transportation Planning Staff (CTPS). In addition to the traditional...

Policy Options and Highway Capacity Needs
One of the recurring criticisms levelled against FHWA's Report to Congress on the Status of the Nation's Highways is that the Report does not go far enough in examining the implications...
