A Framework for ATIS Safety
Advanced Traveler Information Systems utilize advance techniques to acquire, process, and disseminate information to motorists. The main purpose of ATIS is to provide motorists with information...

Establishing a Human Factors Focus and Approach for North Carolina's IVHS Efforts
The paper discusses the behavioral and human factors issues associated with the development and operation of North Carolina's CARAT program (Congestion Avoidance and Reduction for Autos...

Digital Mapping for Road Navigation in Japan
In Japan, more than 300,000 vehicles are presently equipped with car navigation systems. Development of these systems had been greatly aided by the completion of a standardized digital...

Technology Transfer: Encouraging the Use of Advanced Technologies in Your Organization
Encouraging the evaluation, use, and development of advanced technologies throughout an organization presents a special challenge, with the rewards of successful implementation far outweighing...

Arterial Street Incident Detection Using Multiple Data Sources: Plans for ADVANCE
An Advanced Traveler Information System demonstration called ADVANCE is being prepared for implementation on an arterial street network in the suburbs of Chicago. This paper will describe...

Simulation of Daily Climatic Series for the Assessment of Climate Change Impacts on Water Resources
A new approach to the generation of climatic time series for studies of the impact of climate change on water resources is presented. The method adapts a current stochastic weather generator...

Design Hydrographs in Coastal Wetland Watersheds
The use of synthetic unit-hydrographs for hydraulic design in ungaged watersheds has been an accepted practice for over 50 years. In southeastern U.S. coastal regions, which contain extremely...

Minimum Streamflow for Habitat?A Case Study. Menikganga River Diversion Project?Sri Lanka
Determination of minimum streamflows to be left in the stream channel for the sustenance of the downstream habitats becomes a difficult task when quantitative requirements of such habitats...

Nonpoint Source Pollution Model for Agricultural and Rural Watersheds
A dynamic hydrologic and nonpoint source pollution simulation model for agricultural and rural watersheds; capable of simulating rainfall-runoff, soil erosion, sediment transport, mixing...

A Comparison of L-Moments with Method of Moments
A comparison of the Conventional Moments Method (CMM) with the L-Moments Method (LMM) for selecting a distribution is made. Five distributions GEV (Generalized Extreme Value), LNO (Lognormal),...

Numerical Estimation of Macrodispersivities in Heterogeneous Self-similar Aquifers
Numerical simulations of contaminant transport in a stratified aquifer characterized by a self-similar distribution of hydraulic conductivity were performed. Macrodispersivities were calculated...

Simulation of the Propagation of Conserevative Contamination
The hydrodynamic model of the pollutant transport in water bodies was developed and adopted for Volga water supply system of Moscow, which includes five reservoirs and a channel. The model...

Unit Hydrograph Estimation Procedures Using Orthogonal Functions
All unit hydrograph estimation procedures based on orthogonal functions are reviewed in this paper. A more physically based orthogonal function (a gamma function) for unit hydrograph estimation...

Dam-Break Study for Large Floodplain Area - A Case Study
In simulating a dam break flood in a large floodplain, the maximum flood level is sensitive to the off-channel storage volume used in the channel routing. An incorrect estimate of the...

A Two-Dimensional Flow and Hydrogeochemical Transport Model
A two-dimensional flow and hydrogeochemical transport model is designed for estimating the movement and attenuation of chemicals after they are released into subsurface systems. This model...

Simulation of Contaminant Migration Under Conditions of Declining Ground Water Levels
A ground water flow and transport model was developed to simulate the migration of contaminants originating from an industrial site. The development and calibration of the model were based...

Modeling Contaminant Migration from an Unlined Pond
A hybrid one-dimensional (1-D) vertical model coupled with a two-dimensional (2-D) aquifer model was applied to study the fate and transport of arsenic, fluoride, and orthophosphate resulting...

Adjustment of Groundwater Quality Models
Groundwater quality models have been used lately in solving cases dealing with groundwater flow and pollutant transport problems. Finite element method is used in such problems and is...

A Numerical Model for Multiphase Flow and Transport Assessment of Migration of Petroleum Contaminants in the Subsurface
Modeling assessment of the subsurface migration and fate of petroleum hydrocarbons plays a critical role in addressing the environmental impacts of their numerous underground releases...

Investigation of Chloroform Plumes in a Porous Media
A sand box model was used in the laboratory to study the development and stability of the contaminant plume with respect to space and time. Steady, uniform flow velocities were established...
