Defining the Safe Navigable Depth of the Calcasieu River Ship Channel, Louisiana
Field research conducted in the Calcasieu River Ship Channel in Louisiana is described and some results of correlations between the echo sounder records and density measurements are presented....

Development and Modern Dynamics of Alluvial-Accumulative Coasts of the Eastern Black Sea
River regime, river sediment and wave processes are greatly important in the alluvial accumulative coast evolution. The Black Sea coast of the Georgia may be a good example of such coast...

Influence of River Mouth Migrations on the Caucasian Black Sea Coast Development
When studying modern coastal and river-issue processes and comparing last century and modern maps some regularities were revealed. River arms, which are upstream the longitudinal sediment...

State-of-the-Art and Dynamic of Some Beaches of the Bulgarian Black Sea Coast
The considerable decrease of the solid flow off in the sea coastal zone and the intensification of the abrasion impact on the shore determined the increase of the coastal protection activity...

Coastal and Sand Spit Evolution from 1958 to 1992: Saloum River Mouth (Senegal, West Africa)
From the bathymetric map made in 1958 with the Marine Hydrographical Service in France (Number 6147), the 1976 Landsat imagery, the 1981 SPOT simulations, the 1991 SPOT data and the field...

Filtering and Prediction on Freeways Using Markov Models
A Markov compartment model of freeway traffic flow is presented and used to derive a Kalman Filter which tracks a freeway section's density, broken down by destination. The filter is then...

A Dynamic Real-Time Incident Detection System for Urban Arterials?System Architecture and Preliminary Results
This study presents a system which is capable of detecting incidents in real-time and adjusting itself to traffic dynamics through the embedded learning mechanism. The entire system consists...

Overview of the FAST-TRAC IVHS Program
A major new IVHS initiative, called FAST-TRAC, is taking place in Oakland County, Michigan. It originated as a bottom-up strategy for solving mobility and highway safety problems in this...

Optimal Strategy Within a Traffic Control Center
This paper describes part of a new Central Traffic Control System (CTCS), implemented in several sites in Europe, and recently in Haifa, Israel. The CTCS effected in Haifa contains enhanced...

A Neural Network Model for Data Fusion in ADVANCE
As current state of the art technology on smart cars and Smart Highways is processing, applications of advanced technologies in transportation engineering are becoming more and more important....

Simulation of the Dynamic Traffic Flow on Urban Road Network
Methods of performing dynamic traffic assignment are needed to simulate traffic conditions on urban highways during peak periods of congestion. In this paper, the route choice behavior...

Detection of Incidents and Traffic Disturbances in Freeways
This research aims to develop methods for detecting incidents and compression waves through simulation. The detection methods are based on a macroscopic traffic flow model that focuses...

Temporal Variation of Precipitation Trend at Seoul, Korea, 1771-1991
This paper describes temporal variation of annual precipitation trend from 1771 to 1991 at Seoul, Korea. Analysis of the series shows no distinct trend over years. A linear trend would...

Scaling Laws of Gravity Driven Fingering During Organic Liquid Infiltration
Wetting front instability can occur during vertical infiltration of a liquid into porous media, particularly when a fine soil layer is overlying a coarse layer. The result of this instability...

Change of Estuarine Processes Due to Sea Level Rise and Navigation Channel Improvement
To investigate the relationship between the improvement of navigation channels and the change of estuarine environment under various sea level rise scenarios, numerical study was performed...

Hydrology of Wetland Treatment Systems in East Orange County, Florida
Wetlands are increasingly being used as final treatment systems for industrial and domestic wastewater effluent discharges and stormwater runoff discharges. Hydrological monitoring and...

Ecohydrological Processes in Almost Flat Wetlands
In spite of their modest relief almost flat wetlands are able to maintain definite topographically driven groundwater flow systems. Large seepage areas create ecohydrological gradients...

Travel Time in Mountain Basins
An empirical relationship is developed for estimating travel time in high gradient stream channels with natural beds of large gravel, cobbles and random boulders and which are flowing...

Lessons from Hurricane Andrew's Effects on Hydraulic Structures
Documentation and description of Andrew's effects on open channels and other hydraulic structures in South Dade County, Florida, are presented, based on observations made during field...

Back to the Unit Hydrograph Method
In this paper, the basic single area unit hydrograph model is shown to represent a highly complex, rational, link-node model which includes (i) variable effective rainfall distributions...
